Description
[0001] Split from patent application BR 11 2021 007221 7 filed on October 15, 2019. TECHNICAL FIELD
[0002] The present invention relates to constructs, vectors, related host cells and pharmaceutical compositions that enable effective gene therapy, in particular, for diseases due to mutations in genes with a coding sequence (CDS) greater than 5 kb. BACKGROUND OF THE INVENTION
[0003] Gene therapy with adeno-associated viral vectors (AAVs) is safe and effective in humans. AAV-based gene therapy products have been approved in recent years in the US and Europe for hereditary and metabolic diseases, while clinical trials for AAV-based gene therapy approaches for diseases in different therapeutic areas ranging from ophthalmology to hematology and musculoskeletal and metabolic disorders are constantly increasing.
[0004] However, the limited carrying capacity of AAV vectors prevents the development of AAV-based therapies for diseases due to mutations in genes with a coding sequence (CDS) larger than 5 kb (here also referred to as large genes).
[0005] Genetic diseases due to mutations in large genes (listed in Table 1 below) include, among others, Duchenne muscular dystrophy due to mutations in the DMD gene, cystic fibrosis due to mutations in the CFTR gene, Petition 870260074145, dated 07 / 24 / 2026, p. 13 / 259 2 / 192 hemophilia A due to mutations in the F8 gene, dysferlinopathies due to mutations in the DYSF gene, polycystic kidney disease due to a mutation in the PKD gene, Wilson's disease due to a mutation in the ATP7B gene, Huntington's disease due to a mutation in the HTT gene, Niemann-Pick type C due to a mutation in the NPC1 gene.

[0006] In addition, several hereditary retinal degenerations (IRDs) are due to mutations in large genes, as listed in Table 2 below. IRDs affect about 1 in 3,000 people in Europe and the United States (58).
[0007] Among the most frequent and serious IRDs are retinitis pigmentosa (RP), Leber congenital amaurosis (LCA), and Stargardt disease (STGD), which are most often inherited as monogenic conditions, with an overall global prevalence of 1 / 2,000 (1), and are a leading cause of blindness worldwide. Most mutations that cause IRDs occur in genes expressed in photoreceptors. Petition 870260074145, dated 07 / 24 / 2026, p. 14 / 259 3 / 192 neuronal (PR), rods and / or cones in the retina (2).
[0008] Gene therapy holds great promise for the treatment of IRDs. The first adeno-associated viral vector (AAV)-based gene therapy product for a hereditary form of blindness was approved in December 2017 (3). In addition, several other AAV-based products are currently in clinical development for gene therapy of rare and common forms of blindness (4). Although it is now well established that AAV represents, to date, the most efficient gene therapy vehicle for the retina (4,5), its limited payload capacity has hindered its use for conditions requiring the delivery of DNA sequences exceeding 5 kb in size (6) that include not only the transgene but also the cis regulatory elements that are necessary for its expression.
[0009] Examples of disease genes that exceed 5 kb in size are summarized in Table 2 below.

[0010] Stargardt disease (STGD; MIM # 248200) is the most common form of inherited macular degeneration caused by mutations in the ABCA4 gene (CDS: 6822 bp), which encodes the all-trans retinal transporter located in the outer PR segment (7); Usher syndrome type IB (USH1B; MIM # 276900) is the most severe form of RP and deafness caused by mutations in the MY07A gene (CDS: 6648 bp) (8) which encodes the unconventional MY07A, an actin-based motor expressed in both PR and RPE in the retina (9-11).
[0011] Conical rod dystrophy type 3, fundus flavimaculatus, age-related macular degeneration type 2, severe early-onset retinal dystrophy, and retinitis pigmentosa type 19 are also associated with ABCA4 mutations (referred to herein as ABCA4-associated diseases).
[0012] The inventors and others have shown that this limitation can be overcome by using double (up to 9 kb) (6, 12, 13) or triple (up to 14 kb) (14) AAV vectors, each Petition 870260074145, dated 07 / 24 / 2026, page 16 / 259 5 / 192 containing fragments of the coding sequence (CDS) of the large transgene expression cassette. Double and triple AAV vectors exploit the concatemerization and recombination of AAV genomes to reconstitute full-length genomes in cells co-infected with multiple AAV vectors. However, the efficiency of transgene expression achieved with double or triple AAV vectors in photoreceptors, which are the main therapeutic targets for most hereditary retinal diseases, is lower than that achieved with single AAV vectors (6, 14, 15). This may be due to the various limiting steps required for efficient transduction, including proper DNA concatemer formation, heterogeneous mRNA stability, and splicing efficiency across vector junctions.
[0013] The present inventors showed in document WO 2014 / 170480 and Colella et al (15) dual AAV vectors that reconstitute a large gene by splicing (transsplicing), homologous recombination (overlap) or a combination of the two (hybrid), finding that dual transsplicing and hybrid vectors are particularly efficient for the treatment of hereditary retinal degenerations. In addition, Maddalena et al. (14) demonstrated a triple AAV vector approach for genes up to 14 kb. However, the efficiency of transgene expression achieved with dual or triple AAV vectors is lower than that achieved with single AAV vectors (6, 13, 14). This may be due to the various limiting steps required for efficient transduction, including: proper formation of the DNA concatemer, stability of the heterogeneous mRNA and Petition 870260074145, dated 07 / 24 / 2026, page 17 / 259 6 / 192 splicing efficiency through vector junctions. Furthermore, the AAV triple vector strategy produces gene expression levels below the threshold required for a therapeutic approach.
[0014] Therefore, there is still a need for constructs and vectors that can be explored to reconstruct the expression of large genes for effective gene therapy.
[0015] The inventors have now discovered that delivering multiple AAV vectors, each encoding one of the fragments of either reporter or large therapeutic proteins flanked by short split inteins, results in protein trans-splicing and full-length protein reconstitution both in vitro and in vivo.
[0016] Inteins are genetic elements transcribed and translated within a host protein from which they self-excise in a manner similar to a protein intron, leaving no amino acid modifications in the final protein product, in the absence of energy supply, exogenous host-specific proteases, or cofactors (16, 17, 27, 28). Intein activity is context-dependent, with certain peptide sequences surrounding its linking junction (called N- and C-exteins) being necessary for efficient trans-splicing, the most important of which is an amino acid containing a thiol or hydroxyl group (i.e., Cys, Ser, or Thr) as the first residue in the C-extein (18). Split-inteins are a subset of inteins that are expressed as two separate polypeptides. Petition 870260074145, dated 07 / 24 / 2026, page 18 / 259 7 / 192 at the ends of two host proteins and catalyze their trans-splicing resulting in the generation of a single larger polypeptide (19). Inteins, including split inteins, are widely used in biotechnological applications including protein purification and labeling steps (19, 20), as well as the reconstitution of the widely used CRISPR / Cas9 genome editing nuclease (21, 22).
[0017] Several attempts have been made to explore intein-based protein splicing to reconstitute the expression of therapeutic genes, including the Factor gene. VIII, in which heavy and light chain genes fused with Synechocystis sp (Ssp) DnaB intein of Factor VIII have been shown to lead to the reconstitution of Factor VIII in cell culture and in animal models (23, 24). Similarly, a highly functional form of the dystrophin gene was expressed in vitro and in vivo, in which the 6.3 kb Becker dystrophin gene was split into two AAV vectors and each half was fused to split inteins obtained from Synechocystis sp. PCC 6803 (Ssp) DnaB intein or Rhodothermus marinus (Rma) DnaB intein (25). Furthermore, the split intein-mediated protein trans-splicing strategy (namely N. punctiforme DnaE split DnaE) has been reported to reconstitute the large pore-forming subunit of L-type calcium channels from two separate fragments in cardiac cells, (26). US patent 6,544,786 further reports the use of split inteins to deliver a dystrophin minigene.
[0018] The present inventors took advantage of the Petition 870260074145, dated 07 / 24 / 2026, page 19 / 259 8 / 192 intrinsic capacity of split inteins to mediate protein trans-splicing to reconstitute large full-length proteins after their fragmentation into two or three polypeptides flanked by split inteins, whose coding sequences fit into unique AAV vectors. The present invention, therefore, implements large protein cellular reconstitution by providing a target cell with two or more fragments of said large protein fused to split inteins to promote intein-mediated trans-splicing and reconstitute the functional protein. SUMMARY OF THE INVENTION
[0019] The present invention provides gene therapy with AAV vectors for diseases due to gene mutations, in particular, genes with coding regions exceeding 5 kb.
[0020] Based on findings that split-intein-mediated protein transsplicing is used by single-celled organisms to reconstitute proteins, the inventors constructed several AAV vectors, each encoding one of the fragments of either large reporter or therapeutic proteins flanked by short split inteins, resulting in protein trans-splicing and full-length protein reconstitution in vitro and in vivo.
[0021] Advantageously, the reconstitution of disease proteins mediated by AAV-based protein trans-splicing achieved by the present invention provided the expression of greater amounts of target proteins than AAV-based methods for large proteins known in Petition 870260074145, dated 07 / 24 / 2026, page 20 / 259 9 / 192 technique. This is likely due to overcoming several limiting steps required for efficient transduction of double vector-based systems, including: proper DNA concatemer formation, heterogeneous mRNA stability, and splicing efficiency between vector junctions.
[0022] The present invention provides a vector system for expressing a coding sequence in a cell, said coding sequence consisting of a first part (CDS1), a second part (CDS2) and, optionally, a third part (CDS3), said vector system comprising: a) a first vector comprising: - the aforementioned first portion of the aforementioned encoding sequence (CDS1), - a first nucleotide sequence of intein that codes for an N-intein, with said sequence located at the 3' end of CDS1; and b) a second vector comprising: - the aforementioned second portion of the aforementioned encoding sequence (CDS2), - a second nucleotide sequence of intein that codes for a C-intein, said sequence being located at the 5' end of CDS2; whereby when the first vector and the second vector are inserted into a cell, the protein product of the coding sequence is produced by protein splicing; or the aforementioned vector system comprising: a') a first vector comprising: Petition 870260074145, dated 07 / 24 / 2026, page 21 / 259 10 / 192 - the aforementioned first portion of the aforementioned encoding sequence (CDS1),
[0023] - a first intein nucleotide sequence encoding a first N-intein, said sequence being located at the 3' end of CDS1; and b') a second vector comprising: - the aforementioned second portion of the aforementioned encoding sequence (CDS2), - a second nucleotide sequence of intein that codes for a first C-intein, with said sequence located at the 5' end of CDS2; - a third nucleotide sequence of intein that codes for a second N-intein, with said sequence located at the 3' end of CDS2; and c') a third vector comprising: — the aforementioned third part of the said encoding sequence (CDS3) - a fourth intein nucleotide sequence that codes for a second C-intein, said sequence being located at the 5' end of CDS3, wherein the first intein nucleotide sequence is different from the third intein nucleotide sequence and the second intein sequence is different from the fourth intein nucleotide sequence, wherein when the first vector, the second vector, the third vector are inserted into a cell, the protein product of the coding sequence is produced by protein trans-splicing.
[0024] Preferably, in the vector system, the first integer, the second integer, the third integer and the Petition 870260074145, dated 07 / 24 / 2026, page 22 / 259 11 / 192 fourth protein codes for a split protein, preferably, said split protein has a maximum length of 150 amino acids, more preferably, said split protein is a DnaE or DnaB protein.
[0025] According to the present invention, an intein is a segment of a protein that is capable of excising itself and joining the remaining portions (the exteins) with a peptide bond in a process known as protein splicing. The segments are called inteins for the inner protein sequence and exteinos for the outer protein sequence, with the upstream exteins called N-exteins and the downstream exteins called C-exteins, the upstream intein called N-intein and the downstream intein called C-intein.Therefore, in the context of the present invention, an N-intein is an intein fragment located at the N-terminus of (and fused with) the first polypeptide, and a C-intein is an intein fragment located at the C-terminus of (and fused with) the second polypeptide, wherein after the expression of the two polypeptides, the two intein fragments undergo protein trans-splicing and are joined to form a complete intein, and the two polypeptides are joined, wherein when the two polypeptides form a full-length protein, said full-length protein is reconstituted.
[0026] According to the present invention, the first intein sequence is an N-intein sequence and the second intein sequence is a C-intein sequence, wherein said N-intein and said C-intein are preferably derived from the same intein or gene split. Petition 870260074145, dated 07 / 24 / 2026, page 23 / 259 12 / 192 intein. Alternatively, said N-intein and said C-intein derive from two different intein genes that are capable of undergoing the trans-splicing reaction naturally or are modified for this purpose. Consequently, the same gene may be from the same organism or from different organisms. For example, the widely used split inteins derive from the DnaE gene of different organisms. According to the present invention, when the coding sequence of the protein of interest is split into two portions, the N-intein coding sequence is fused in frame with the coding sequence for the N-terminal portion of the protein of interest; the C-intein coding sequence is fused in frame with the coding sequence for the C-terminal portion of the sequence of interest. After expression of the two precursor fusion proteins, the inteins undergo autocatalytic excision and form a linked extein, for example, the reconstituted protein of interest.
[0027] According to the present invention, the coding sequence of the protein of interest can be divided into three portions. Consequently, the first intein sequence is an N-intein sequence and the second intein sequence is a C-intein sequence, wherein the first intein coding sequence is fused into the C-terminus structure to the coding sequence for the N-portion of the protein of interest, and the second intein coding sequence is fused into the N-terminus structure to the coding sequence for the intermediate portion of the protein of interest. Consequently, said N-intein and said C-intein are preferably Petition 870260074145, dated 07 / 24 / 2026, page 24 / 259 13 / 192 derived from the same intein gene or split intein gene. Alternatively, said N-intein and said kintein derive from two different intein genes that are capable of undergoing the trans-splicing reaction naturally or are modified for this purpose. Consequently, the same gene may be from the same organism or from different organisms. Within the present configuration, the third intein is an N-intein coding sequence fused in-frame to the coding sequence for the C-terminus of the mid-portion of the protein of interest, and the fourth intein is a C-intein coding sequence fused in-frame to the sequence coding for the N-terminus of the C-portion of the protein of interest. Consequently, said third and fourth inteins are preferably derived from the same intein or split intein gene.Alternatively, said N-intein and said Kintein derive from two different intein genes that are capable of undergoing the trans-splicing reaction naturally or are modified for this purpose. Consequently, the same gene may be from the same organism or from different organisms. Within the scope of the present invention, said first and second inteins and said third and fourth inteins derive from different intein genes, and the first intein selectively ligates to the second intein, while the third intein selectively binds to the fourth intein.
[0028] In the present invention, when the first vector, the second vector and, optionally, the third vector are inserted into a cell, at least two fusion proteins or three fusion proteins are formed and upon entering Petition 870260074145, dated 07 / 24 / 2026, p. 25 / 259 14 / 192 contact with the aforementioned two or three fusion proteins, the protein product of the coding sequence is produced. The contact step is performed under conditions that allow the N-intein to bind to the C-intein.
[0029] In the present invention, when the first vector, the second vector, and the third vector are inserted into a cell, three independent polypeptides are produced and the full-length protein is produced via transsplicing. Fundamental to the development of the three AAV intein vectors has been the use of different inteins, i.e., DnaE and DnaB, which do not exhibit cross-reaction, thus avoiding improper trans-splicing between the polypeptides produced by the first and third vectors.
[0030] According to preferred embodiments of the present invention, a vector system for expressing the coding sequence of a gene of interest in a cell comprises two vectors, each vector comprising a portion of said coding sequence flanked by an intein sequence, wherein the 5' end of said coding sequence is flanked at the 3' end by an N-intein sequence, and the 3' end of the coding sequence of the gene of interest is flanked by a C-intein sequence, such that when both vectors are expressed in a cell, two fusion proteins are produced and the full-length protein of interest is generated as a result of a spontaneous trans-splicing reaction.
[0031] According to another embodiment Petition 870260074145, dated 07 / 24 / 2026, page 26 / 259 15 / 192 preferred version of the invention, the vector system for expressing the coding sequence of a gene of interest in a cell comprises three vectors, each vector comprising a portion of said coding sequence flanked by an intein sequence, wherein the coding sequence is divided into three portions such that the 5' end of said coding sequence is flanked at the 3' end by a first N-intein sequence; the middle portion of said coding sequence is flanked at the 5' end by a first C-intein, and at the 3' end with a second N-intein;The 3' portion of the aforementioned coding sequence is flanked at the 5' end by a second C-intein, so that when all three vectors are expressed in a cell, three fusion proteins are produced and the full-length protein of interest is generated as a result of a spontaneous trans-splicing reaction, in which the first N-intein reacts with the first C-intein and the second N-intein reacts with the second C-intein.
[0032] The split inteins of the invention may be encoded by a gene that is then modified to encode two separate fragments of inteins, for example, split inteins; alternatively, naturally occurring split inteins are encoded by two separate genes; for example, in cyanobacteria, DnaE, the catalytic α subunit of DNA polymerase III, is encoded by two separate genes, dnaE-n and dnaE-c. Preferred inteins within the present invention are inteins derived from protein inteins (e.g., mini inteins) or inteins Petition 870260074145, dated 07 / 24 / 2026, page 27 / 259 16 / 192 divided into proteins that form integers through the trans-splicing reaction, which are 150 aa in length or less.

Within the scope of the present invention are fragments or variants of naturally occurring or modified inteins that retain trans-splicing activity.

DETAILED DESCRIPTION OF THE INVENTION Gene Therapy
[0101] During the last decade, gene therapy has been applied to the treatment of diseases in hundreds of clinical trials. Several tools have been developed to deliver genes to human cells; among them, viruses Petition 870260074145, dated 07 / 24 / 2026, page 56 / 259 Genetically modified 45 / 192 viruses, including adeno-associated viruses, are currently among the most popular tools for gene delivery.
[0102] Most systems contain vectors that are capable of accommodating genes of interest and helper cells that can provide the viral structural proteins and enzymes to enable the generation of infectious viral particles containing vectors.
[0103] Adeno-associated viruses are a family of viruses that differ in nucleotide and amino acid sequence, genome structure, pathogenicity, and host range. This diversity offers opportunities to use viruses with different biological characteristics to develop different therapeutic applications.
[0104] As with any delivery tool, the efficiency, ability to target a particular tissue or cell type, expression of the gene of interest, and safety of adeno-associated virus-based systems are important for the successful application of gene therapy. Significant efforts have been devoted to these research areas in recent years. Several modifications have been made to adeno-associated virus-based vectors and helper cells to alter gene expression, target delivery, improve viral titers, and increase safety.
[0105] The present invention represents an improvement in this design process, insofar as it acts to efficiently deliver genes of interest with a size that exceeds the payload limit for a single vector based on Petition 870260074145, dated 07 / 24 / 2026, page 57 / 259 46 / 192 adeno-associated virus.
[0106] Viruses are logical tools for gene delivery. They replicate inside cells and have therefore developed mechanisms to enter cells and use the cellular machinery to express their genes. The concept of virus-based gene delivery is to manipulate the virus so that it can express the gene of interest. Depending on the specific application and type of virus, most viral vectors contain mutations that hinder their ability to replicate freely as wild-type viruses in the host.
[0107] Viruses from several different families have been modified to generate viral vectors for gene delivery. These viruses include retroviruses, lentiviruses, adenoviruses, adeno-associated viruses, herpes simplex viruses, picornaviruses, and alphaviruses.
[0108] The present invention preferably employs adeno-associated viruses. Therefore, virus-based vectors for gene delivery include, without limitation, adenoviral vectors, adeno-associated viral vectors (AAVs), pseudotyped AAV vectors, herpes viral vectors, retroviral vectors, lentiviral vectors, baculoviral vectors.
[0109] An ideal adeno-associated virus-based vector for gene delivery must be efficient, cell-specific, regulated, and safe. Delivery efficiency is important because it can determine the effectiveness of the therapy. Current efforts aim to achieve cell-type-specific infection and gene expression with adeno-associated viral vectors. Furthermore, vectors Petition 870260074145, dated 07 / 24 / 2026, page 58 / 259 47 / 192 adeno-associated viral genes are being developed to regulate the expression of the gene of interest, since therapy may require regulated or long-lasting expression. Safety is an important issue for viral gene delivery because most viruses are pathogenic or have pathogenic potential.
[0110] Adeno-associated virus (AAV) is a small virus that infects humans and some other primate species. Currently, AAV is not known to cause disease, and consequently, the virus causes a very mild immune response. Gene therapy vectors using AAV can infect dividing and quiescent cells and persist in an extrachromosomal state without integrating into the host cell genome. These characteristics make AAV a very attractive candidate for creating viral vectors for gene therapy and for creating isogenic models of human diseases.
[0111] Wild-type AAV has attracted considerable interest from gene therapy researchers due to a number of characteristics. The main one is the apparent lack of pathogenicity of the virus. It can also infect non-dividing cells and has the ability to stably integrate into the host cell genome at a specific location (designated AAVS1) on human chromosome 19. This characteristic makes it somewhat more predictable than retroviruses, which present the threat of random insertion and mutagenesis, sometimes followed by the development of cancer. The AAV genome integrates more frequently at the aforementioned site, while random incorporations at Petition 870260074145, dated 07 / 24 / 2026, page 59 / 259 48 / 192 genome sequencing occurs with negligible frequency. The development of AAVs as gene therapy vectors, however, eliminated this integrative capacity by removing the rep and cap from the vector DNA. The desired gene, along with a promoter to drive gene transcription, is inserted between inverted terminal repeats (ITRs) that aid in the formation of the concatemer in the nucleus after the single-stranded vector DNA is converted by host cell DNA polymerase complexes into double-stranded DNA. AAV-based gene therapy vectors form episomal concatemers in the host cell nucleus. In non-dividing cells, these concatemers remain intact throughout the life of the host cell. Upon cell division, the AAV DNA is lost through cell division, since episomal DNA is not replicated along with host cell DNA.Random integration of AAV DNA into the host genome is detectable, but occurs at a very low frequency. AAVs also exhibit very low immunogenicity, apparently restricted to the generation of neutralizing antibodies, although they do not induce any clearly defined cytotoxic response. This characteristic, along with the ability to infect quiescent cells, demonstrates their dominance over adenoviruses as vectors for human gene therapy. AAV genome, transcriptome and proteome
[0112] The AAV genome is constructed of single-stranded deoxyribonucleic acid (ssDNA), with positive or negative detection, which is approximately 4.7 kilobases in length. The genome comprises terminal repeats Petition 870260074145, dated 07 / 24 / 2026, page 60 / 259 49 / 192 inverted receptors (ITRs) at both ends of the DNA strand and two open reading frames (ORFs): rep and cap. The former is composed of four overlapping genes that encode Rep proteins necessary for the AAV life cycle, and the latter contains overlapping nucleotide sequences of capsid proteins: VP1, VP2, and VP3, which interact with each other to form a capsid of icosahedral symmetry. ITR Sequences
[0113] Inverted Terminal Repeat (ITR) sequences comprise 145 bases each. They were named for their symmetry, which has proven necessary for the efficient multiplication of the AAV genome. Another property of these sequences is their ability to form a hairpin, which contributes to so-called self-priming, allowing for primase-independent synthesis of the second DNA strand. ITRs have also been shown to be necessary for the integration of AAV DNA into the host cell genome (19 chromosomes in humans) and its rescue, as well as for the efficient encapsulation of AAV DNA combined with the generation of fully assembled deoxyribonuclease-resistant AAV particles.
[0114] With regard to gene therapy, ITRs appear to be the only sequences required in cis alongside the therapeutic gene: structural (cap) and packaging (rep) genes can be delivered in trans. With this assumption, many methods have been established for the efficient production of recombinant AAV vectors (rAAV) containing a reporter or therapeutic gene. However, it has also been published that ITRs are not the only elements required in cis for the Petition 870260074145, dated 07 / 24 / 2026, page 61 / 259 50 / 192 effective replication and encapsidation. Some research groups have identified a sequence designated as cis-acting Rep-dependent element (CARE) within the coding sequence of the rep gene. CARE has been shown to enhance replication and encapsidation when present in cis. AAV serotypes
[0115] To date, dozens of different AAV variants (serotypes) have been identified and classified (60). All known serotypes can infect cells of various types of diverse tissues. Tissue specificity is determined by the capsid serotype, and pseudotyping AAV vectors to alter their tropism range will likely be important for their use in therapy. Pseudotyped AAV vectors are those that contain the genome of one AAV serotype in the capsid of a second AAV serotype; for example, an AAV2 / 8 vector contains the AAV8 capsid and the AAV2 genome (61). These vectors are also known as chimeric vectors. SEROTYPE 2
[0116] Serotype 2 (AAV2) has been the most extensively examined to date. AAV2 exhibits natural tropism for skeletal muscle, neurons, vascular smooth muscle cells, and hepatocytes. Three cellular receptors have been described for AAV2: heparan sulfate proteoglycan (HSPG), integrin qnb5, and fibroblast growth factor receptor 1 (FGFR-1). The first functions as a primary receptor, while the latter two have coreceptor activity and allow AAV to enter the cell via receptor-mediated endocytosis. The results of this study were Petition 870260074145, dated 07 / 24 / 2026, page 62 / 259 51 / 192 contested by Qju, Handa, et al. HSPG functions as the primary receptor, although its abundance in the extracellular matrix may eliminate AAV particles and impair infection efficiency.
[0117] Studies have shown that serotype 2 of the virus (AAV-2) apparently kills cancer cells without harming healthy ones. Our results suggest that adeno-associated virus type 2, which infects most of the population but has no known harmful effects, kills several types of cancer cells but has no effect on healthy cells, said Craig Meyers, professor of immunology and microbiology at Penn State College of Medicine in Pennsylvania. This could lead to a new anticancer agent. OTHER SEROTYPES
[0118] Although AAV2 is the most popular serotype in several AAV-based studies, other serotypes have been shown to be more effective as gene delivery vectors. For example, AAV6 appears much better at infecting airway epithelial cells, AAV7 exhibits a very high transduction rate of murine skeletal muscle cells (similar to AAV1 and AAV5), AAV8 excels at transducing hepatocytes and photoreceptors, and AAV1 and 5 have proven very efficient at delivering genes to vascular endothelial cells. In the brain, most AAV serotypes show neuronal tropism, while AAV5 also translates astrocytes. AAV6, a hybrid of AAV1 and AAV2, also shows lower immunogenicity than AAV2.
[0119] Serotypes may differ with respect to the receptors to which they are bound. For example, the Petition 870260074145, dated 07 / 24 / 2026, page 63 / 259 52 / 192 transduction of AAV4 and AAV5 can be inhibited by soluble sialic acids (differently for each of these serotypes), and AAV5 has been shown to enter cells via the platelet-derived growth factor receptor. Novel AAV variants, such as quad tyrosine mutants or AAV 2 / 7m8, have been shown to transduce the outer retina from the vitreous in small animal models (62, 63). Another AAV mutant, termed ShHIO, is an AAV6 variant with enhanced glial tropism after intravitreal administration (64). Another AAV mutant with particularly advantageous tropism for the retina is AAV2 (quad YF) (65).
[0120] The gene delivery vehicles of the present invention can be administered to a patient. Such administration can be in vivo or ex vivo. A skilled worker would be able to determine the appropriate dosage rates. The term administered includes delivery by viral or non-viral techniques.

The pharmaceutical composition may be for human or animal use. Typically, a physician will determine the actual dosage that will be most appropriate for an individual subject and will vary with the age, weight and response of the particular individual.
[0123] The composition may optionally comprise a pharmaceutically acceptable carrier, diluent, excipient, or adjuvant. The choice of pharmaceutical carrier, excipient, or diluent may be selected in relation to the intended route of administration and standard pharmaceutical practice. Pharmaceutical compositions may comprise, as—or in addition to—the carrier, excipient, or diluent, any suitable binder(s), lubricant(s), suspending agent(s), coating agent(s), solubilizing agent(s), and other carrier agents that may assist or enhance viral entry at the target site (such as, for example, a lipid delivery system). When appropriate, pharmaceutical compositions may be administered by either or Petition 870260074145, dated 07 / 24 / 2026, page 65 / 259 54 / 192 more than: inhalation, in the form of a suppository or pessary, topically in the form of a lotion, solution, cream, ointment or powder for sprinkling, by the use of a skin patch, orally in the form of tablets containing excipients such as starch or lactose, or in capsules or ovules, either alone or in a mixture with excipients, or in the form of elixirs, solutions or suspensions containing flavoring or coloring agents; preferably, they may be injected parenterally, for example, intracavernosally, intravenously, intramuscularly or subcutaneously. For parenteral administration, the compositions may be best used in the form of a sterile aqueous solution which may contain other substances, for example, salts or monosaccharides sufficient to make the solution isotonic with blood. For oral or sublingual administration, the compositions can be administered in the form of tablets or lozenges, which can be formulated in a conventional manner.A preferred formulation is one in which the vector system is administered topically into the conjunctival sac or subconjunctivally, preferably administered 1 to 10 times daily, preferably for 1 to 6 months, preferably for 1 to 30 days.

[0125] Preferably, the pharmaceutical composition of the invention is for topical ocular use, and is therefore an ophthalmic composition. Petition 870260074145, dated 07 / 24 / 2026, page 66 / 259 55 / 192
[0126] The vector system, according to the present invention, can be administered by any convenient route, however the preferred route of administration is topically on the ocular surface and especially topically on the cornea. An even more preferred route is instillation into the conjunctival sac.
[0127] It is a specific objective of the present invention, the use of the vector system for the production of an ophthalmic composition to be administered topically to the eye for medical use.
[0128] More generally, a preferred embodiment of the present invention is a composition formulated for topical application to a local, superficial or restricted area of the eye and / or eye adnexa comprising the vector system optionally in conjunction with one or more pharmaceutically acceptable additives (such as diluents or vehicles).
[0129] As used in this descriptive report, the terms vehicle, diluent, carrier and additive are interchangeable.
[0130] The ophthalmic compositions of the invention may be in the form of a solution, emulsion or suspension (eye drops), ointment, gel, aerosol, mist or liniment together comprising a pharmaceutically acceptable, eye-tolerated and compatible ophthalmic vehicle of the active ingredient.

The ophthalmic solution may also include an ophthalmologically acceptable surfactant to aid in the dissolution of the vector system. Ophthalmic solution formulations may be prepared by dissolving the vector system in a physiologically acceptable isotonic aqueous buffer.
[0148] In order to prepare sterile ophthalmic ointment formulations, the Vector system can be combined with a preservative in a suitable vehicle, such as mineral oil, liquid lanolin or white petrolatum. Sterile ophthalmic gel formulations can be prepared by suspending the Vector system in a hydrophilic base prepared from the combination of, for example, carbopol-940 or similar, according to the published formulations for analogous ophthalmic preparations; preservatives and tonicity agents may be incorporated.

For example, the composition is incorporated into or coated within said polymer. The composition is chemically bonded or physically trapped by the polymer. The polymer is hydrophobic or hydrophilic. The polymer device comprises various physical arrangements. Exemplary physical forms of the polymer device include, but are not limited to, a film, a frame, a chamber, a sphere, a microsphere, a stent, or other structure. The polymer device has internal and external surfaces. The device has one or more internal chambers. These chambers contain one or more compositions.

[0152] Natural polyanionic mucoadhesive polymers Petition 870260074145, dated 07 / 24 / 2026, page 74 / 259 Examples of 63 / 192 or semi-synthetic materials from which the device can be formed include, but are not limited to, polygalacturonic acid, hyaluronic acid, carboxymethylamylose, carboxymethylchitin, chondroitin sulfate, heparin sulfate, and mesoglycan. In one embodiment, the device comprises a biocompatible polymer matrix that may optionally be biodegradable in whole or in part. A hydrogel is an example of a suitable polymer matrix material. Examples of materials that can form hydrogels include polylactic acid, polyglycolic acid, PLGA polymers, alginates and alginate derivatives, gelatin, collagen, agarose, natural and synthetic polysaccharides, polyamino acids such as polypeptides, particularly poly(lysine), polyesters such as polyhydroxybutyrate and poly-epsilon.- caprolactone, polyanhydrides; polyphosphazines, polyvinyl alcohols), poly(alkylene oxides) particularly polyethylene oxides), poly(allylamines) (PAM), poly(acrylates), modified styrene polymers such as poly(4-aminomethylstyrene), pluronic polyols, polyoxamers, poly(uronic acids), poly(vinylpyrrolidone) and copolymers of the foregoing, including graft copolymers. In another embodiment, the structures may be fabricated from a variety of synthetic polymers and naturally occurring polymers, such as, but not limited to, collagen, fibrin, hyaluronic acid, agarose and laminin-rich gels.
[0153] A preferred material for hydrogel is alginate or modified alginate material. The molecules of Petition 870260074145, dated 07 / 24 / 2026, page 75 / 259 64 / 192 Alginate polysaccharides are composed of monomers of β-D-mannuronic acid (M units) and L-guluronic acid (G units) that vary in proportion and sequential distribution along the polymer chain. Alginate polysaccharides are polyelectrolyte systems that have a strong affinity for divalent cations (e.g., Ca+2, Mg+2, Ba+2) and form stable hydrogels when exposed to these molecules.
[0154] The device is administered topically, subconjunctivally or into the episcleral space, subcutaneously or intraductally. Specifically, the device is placed on or just below the surface of an ocular tissue. Alternatively, the device is placed within a lacrimal duct or gland. The composition incorporated in or on the polymer is released or diffuses from the device.
[0155] In one embodiment, the composition is incorporated or coated onto a contact lens or drug delivery device, from which one or more molecules diffuse away from the lens or device or are released in a temporally controlled manner. In this embodiment, the contact lens composition remains on the ocular surface, e.g., if the lens is required for vision correction, or the contact lens dissolves over time, simultaneously releasing the composition into adjacent tissues. Similarly, the drug delivery device is optionally biodegradable or permanent in various embodiments.
[0156] For example, the composition is incorporated into or coated onto said lenses. The composition is chemically bonded or physically held in place by the lens polymer.

[0158] Within the scope of the invention are compositions formulated as a gel or gel-like substance, cream, or viscous emulsions. It is preferred that said compositions comprise at least one gelling component, polymer, or other suitable agent for increasing the viscosity of the composition. Any gelling component known to a person skilled in the art, which Petition 870260074145, dated 07 / 24 / 2026, page 78 / 259 67 / 192 has no harmful effect on the area to be treated and is applicable in the formulation of pharmaceutical compositions and compounds for topical administration to the skin, eyes or mucous membranes, it may be used. For example, the gelling component can be selected from the group of: acrylic acids, carbomer, carboxypolymethylene, such materials sold by BF Goodrich under the trade name Carbopol (e.g., Carbopol 940), polyethylene-polypropylene glycols, such materials sold by BASF under the trade name Poloxamer (e.g., Poloxamer 188), a cellulose derivative, e.g., hydroxypropyl cellulose, hydroxyethyl cellulose, hydroxyethylene cellulose, methyl cellulose, carboxymethyl cellulose, alginic acid-propylene glycol ester, polyvinylpyrrolidone, veegum (aluminum magnesium silicate), Pemulen, Simulgel (such as Simulgel 600, Simulgel EG and Simulgel NS), Capigel, Colafax, Plasdones and the like and mixtures thereof.
[0159] A gel or gel-like substance according to the present invention comprises, for example, less than 10% w / w water, for example, less than 20% w / w water, for example, at least 20% w / w water, such as at least 30% w / w water, for example, at least 40% w / w water, such as at least 50% w / w water, for example, at least 75% w / w water, such as at least 90% w / w water, for example, at least 95% w / w water. Preferably, said water is deionized water.
[0160] The gel-like substances of the invention include a hydrogel, a colloidal gel formed as a dispersion in water or another aqueous medium. Thus, a hydrogel Petition 870260074145, dated 07 / 24 / 2026, p. 79 / 259 68 / 192 is formed after the formation of a colloid in which a dispersed phase (the colloid) has combined with a continuous phase (i.e., water) to produce a viscous, jelly-like product; for example, coagulated silicic acid. A hydrogel is a three-dimensional network of hydrophilic polymer chains that are cross-linked by chemical or physical bonds. Due to the hydrophilic nature of the polymer chains, hydrogels absorb water and swell. The swelling process is the same as the dissolution of non-cross-linked hydrophilic polymers. By definition, water constitutes at least 10% of the total weight (or volume) of a hydrogel.
[0161] Examples of hydrogels include synthetic polymers such as polyhydroxyethyl methacrylate and chemically or physically crosslinked polyvinyl alcohol, polyacrylamide, poly(N-vinylpyrrolidone), polyethylene oxide, and hydrolyzed polyacrylonitrile. Examples of hydrogels that are organic polymers include hydrogels based on covalently or ionically crosslinked polysaccharides, such as polyvalent metal salts of alginate, pectin, carboxymethylcellulose, heparin, hyaluronate, and hydrogels of chitin, chitosan, pullulan, gellan, and xanthan gum. The particular hydrogels used in our experiment were a cellulose compound (i.e., hydroxypropylmethylcellulose [HPMC]) and a high molecular weight hyaluronic acid (HA). Hyaluronic acid is a polysaccharide produced by various tissues of the body. US patent 5,166,331 discusses the purification of different fractions of hyaluronic acid for use as a substitute for intraocular fluids and as a Petition 870260074145, dated 07 / 24 / 2026, page 80 / 259 69 / 192 topical ophthalmic drug carrier.

Macromolecular formulations for intraocular use are known. See, for example, US patent applications serial numbers US 11 / 370,301; US 11 / 364,687; US 60 / 721,600; US 11 / 116,698 and US 60 / 567,423; US 11 / 695,527. The use of multiple active agents is known as high-viscosity hyaluronic acid. See, for example, the serial numbers of patent applications US 10 / 966,764; US 11 / 091,977; US 11 / 354,415; US 60 / 519,237; US 60 / 530,062 and US 11 / 695,527.

Suitable host cells are known in the art and include, for example, DH5a, E. coli cells, Chinese hamster ovary cells, monkey VERO cells, COS cells, HEK293 cells and the like.In the case of ex vivo gene therapy, a host cell can be a cell isolated from a patient, for example, hematopoietic stem cells, which after the introduction of the transgene is reintroduced into the patient in need. Viral delivery systems based on AAVs
[0166] The construction of an AAV vector can be carried out following procedures and using techniques known to a skilled technician. The theory and practice for the construction of adeno-associated viral vectors and their use in therapy are illustrated in several scientific and patent publications (the following bibliography is here).

[0169] An intein is a segment of a protein that is capable of being excised and joined to the remaining portions (the exteins) with a peptide bond in a process known as protein splicing. The segments are called intein for the inner protein sequence and extein for the outer protein sequence, with upstream exteins called N-exteins and downstream exteins called C-exteins. The products of the protein splicing process are two stable proteins: the mature protein and the intein.
[0170] Inteins can also exist as two fragments encoded by two genes transcribed and translated separately, here called split inteins.
[0171] Proteins of the present invention include, without limitation, split proteins listed in the New England Biolabs Protein database, disclosed in (66).
[0172] Split inteins can be produced from inteins by first removing the endonuclease homing domain sequence to produce a mini intein. This mini intein can then be split at one or more designed sites via protein sequence alignments with inteins of known crystal structures to generate split inteins, tested for trans-splicing activity according to the protocols included in this disclosure.
[0173] Split proteins can be further improved in desirable characteristics, including Petition 870260074145, dated 07 / 24 / 2026, page 84 / 259 73 / 192 activity, efficiency, generality and stability through site-directed mutagenesis or modifications of intein sequences based on rational design and / or through directed evolution using methods such as functional selection, phage display and ribosome display.
[0174] An example of split inteins are the inteins derived from DnaE, which is the catalytic α subunit of DNA polymerase III in cyanobacteria, encoded by two separate genes, dnaE-n and dnaE-c. The intein encoded by the dnaE-n gene is referred to here as the N-intein. The intein encoded by the dnaE-c gene is referred to here as the C-intein. Generally, the N-part of a split intein is referred to as the N-intein and the C-part of a split intein is referred to as the C-intein. Split inteins self-associate and catalyze the trans-splicing activity of the protein (here trans splicing).
[0175] Other examples of split inteins of the present invention comprise Nostoc punctiforme (Npu) DnaE inteins (27, 28)), indicated in Table 3 below as SEQ ID 1 encoded by the nucleotide sequence NpuDnaE-n and SEQ ID 2 encoded by the nucleotide sequence Npu-DnaE-c; the Rhodothermus marinus DnaB (Rma) (29) intein indicated in the table below as SEQ ID 4 encoded by the nucleotide sequence Rma-DnaB-n and SEQ ID 5 encoded by the nucleotide sequence Rma-DnaB-c; N- and C-inteins mutated wherein the Nl intein is from Npu DnaE (SEQ ID 5) and the Cl intein is from Synechocystis strain PCC6803 (Ssp (SEQ ID 6), respectively (30); the Synechocystis strain PCC6803 Nintein and Cintein are Petition 870260074145, dated 07 / 24 / 2026, page 85 / 259 74 / 192 included as SEQ ID 13 and 14, respectively, in the Table below. Other intein systems may also be used. For example, a synthetic fast intein based on dnaE intein, the Cfa-N and Cfa-C intein pair, has been described (e.g., (31) and in WO 2017 / 132580, incorporated herein by reference). Additional internals have been described in U.S. Patent No. 8,394,604, including Ssp GyrB intein, Ssp DnaX intein, Ter DnaE3, Ter ThyX intein, and Cne Prp8 intein. Other internals within the present invention are the internals disclosed in WO2018071868, wherein the first pair of internals is listed in the table below and named as SEQ ID 9 (Nintein) and SEQ ID 10 (Kintein); A second pair of internals is listed, for example, SEQ ID 11 and SEQ ID 12.
[0176] Alternatively, the intein system may be a ligand-dependent intein that exhibits no or minimal protein splicing activity in the absence of ligand (e.g., small molecules such as 4-hydroxytamoxifen, peptides, proteins, polynucleotides, amino acids, and nucleotides). Ligand-dependent inteins include, for example, those described in US document 2014 / 0065711 A1, which is incorporated herein by reference. Table 3.

[0177] As described in this descriptive report, within the scope of the present invention are inteins originating from the same gene of different organisms, retaining trans-splicing activity. As a non-limiting example, the split DNA-E intein can be derived from split inteins of the DnaE gene (e.g., alpha subunit of DNA polymerase III) from cyanobacteria including Nostoc punctiforme (Npu), Synechocystis sp. PCC6803 (Ssp), Fischerella sp. PCC 9605, Scytonema tolypothrichoidesf, Cyanobacteria bacterium SW_9_47_5, Nodularia spumigena, Nostoc flagelliformi, Crocosphaera watsonii WH 8502, Chroococcidiopsis cubana CCALA 043, Trichodesmium erythraeum. As another example, the DNA-B ssplit intein can be derived from the DnaB gene of cyanobacteria including R. marinus (Rma), Synechocystis sp. PC6803 (Ssp), Porphyra purpurea chloroplast (Ppu) which are described for example in (59).
[0178] Therefore, the split inteins of the invention can be 100% identical, 98%, 80%, 75%, 70%, 65%, or 50% identical to naturally occurring inteins, wherein said inteins retain the ability to undergo trans-splicing reactions. Within the scope of the present invention are Petition 870260074145, dated 07 / 24 / 2026, p. 88 / 259 77 / 192 fragments of naturally occurring or modified inteins that retain trans-splicing activity.

[0183] Therefore, within the scope of the present invention are also variants and fragments of split inteins of the inteins of the invention that retain trans-splicing activity.
[0184] Interestingly, it has been reported that internal Petition 870260074145, dated 07 / 24 / 2026, p. 89 / 259 78 / 192 retained functional features that ensure their splicing activity. In particular, four intein motifs were identified (see below for their consensus sequence): AH blocks (Pietrokovski 1994 and Perler 1997) and N2 and N4 blocks (Pietrokovski 1998). The A, N2, B, N4, F, and G blocks are involved in protein splicing. The O, D, E, and H blocks are in the endonuclease domain, which is absent from split inteins. Thus, split inteins retain conserved motifs that are essential for trans-splicing activity. (Intein Database, published in [Perler, FB (2002). InBase, the Intein Database.

[0185] Although no residue is invariant, Ser and Cys in Block A, His in Block B, His, Asn and Ser / Cys / Thr in Block G are the most conserved residues in splice motifs.

[0188] In summary, the activity of interna is context-dependent, with certain peptide sequences around its linking junction (called N- and C-exsteines) being required for efficient trans-splicing to occur, the most important of which is an amino acid containing a nucleophilic element thiol or hydroxyl group (i.e., Cys, Ser, or Thr) as the first residue in the C-exsteine.
[0189] The present inventors used intein-mediated protein transplication in order to reconstitute large proteins in vivo. The split intes encoded by the inteina gene sequences are produced as precursor polypeptides, which through their structural complementarity can reassemble and catalyze a protein transsplicing reaction.
[0190] In the context of protein trans-splicing, the N-intein gene is fused into the structure with the sequence encoding the N-terminal portion of the protein of interest; the C-intein gene is fused into the structure with the sequence encoding the C-terminal portion of the sequence of interest. After Petition 870260074145, dated 07 / 24 / 2026, page 92 / 259 81 / 192 the expression of the two precursor fusion proteins, the inteins undergo autocatalytic excision and form an extein linked, for example, to the reconstituted protein of interest.
[0191] Therefore, the reconstitution of a protein of interest requires the division of said protein into two or three fragments, whose coding sequences are cloned separately into the AAV vector, fused to an N- or C-Intein and under the control of a promoter. The cleavage points for each protein are selected taking into account the need for amino acids at the junction point (e.g., the presence of an amino acid containing a nucleophilic thiol or hydroxyl group (i.e., Cys, Ser, or Thr) as the first residue in the C-Intein), as well as the preservation of the integrity of critical protein domains in order to favor proper protein folding and the stability of each precursor polypeptide of the Intein polypeptide and the resulting reconstituted protein.
[0192] In particular, the present inventors selected junction points within two proteins of interest: the ABCA4 protein is split into the amino acids Cys1150, Ser1168, Ser1090 and a split intein is inserted at the junction point. The CEP290 protein is split into amino acids Cys1076, Ser1275, Cys929 and 1474; Ser453 and Cys1474. Signs of degradation
[0193] Regulated protein degradation protects cells from misfolded, aggregated, or otherwise abnormal proteins, and also controls the levels of proteins that have evolved for a short lifespan in vivo and is largely mediated by the ubiquitin (Ub) proteasome system (UPS) and Petition 870260074145, dated 07 / 24 / 2026, page 93 / 259 82 / 192 via autophagy-lysosome pathways, with molecular chaperones being a part of both systems. Degradation signals are protein characteristics that make them targets of protein degradation pathways, resulting in a decrease in their half-life. In particular, N-degrons and C-degrons are degradation signals whose main determinants are, respectively, the N-terminal and C-terminal residues of cellular proteins. N-degrons and C-degrons include, to varying extents, adjacent sequence motifs and also internal lysine residues that function as polyubiquitylation sites.
[0194] Within the meaning of the present invention, internal degrons are defined as degradation signals located within a protein sequence neither at the N-terminus nor the C-terminus and whose functionally essential elements do not include N-terminus residues or C-terminus residues and mediate protein degradation.
[0195] Degron pathways comprise sets of proteolytic systems whose unifying characteristic is the ability to recognize proteins containing N- or C- or internal degrons, thus causing the degradation of these proteins by the 26S proteasome or autophagy.
[0196] E. coli dihydrofolate reductase (ecDHFR) is a 159-residue enzyme that catalyzes the reduction of dihydrofolate to tetrahydrofolate, an essential cofactor for several steps in primary prokaryotic metabolism. Numerous DHFR inhibitors have been developed as drugs, and one such inhibitor, trimethoprim (TMP), inhibits ecDHFR much more potently than mammalian DHFR. This Petition 870260074145, dated 07 / 24 / 2026, page 94 / 259 83 / 192 large therapeutic window makes TMP biologically silent in mammalian cells. The specificity of the ecDHFR-TMP interaction, along with the commercial availability and attractive pharmacological properties of TMP, makes this protein-ligand pair ideal for development as a degradation system. (69) Thus, the presence of the DHFR amino acid sequence, preferably the ecDHFR amino acid sequence, within a protein, functions as a target signal for the proteasome system, resulting in protein degradation. In the presence of TMP, the protein in question is stabilized.
[0197] Conveniently, degron signals derived from ecDHFR carrying dot points developed by Iwamoto et al. include three amino acid mutations, R12Y, Y100I and G67S (69) which confers functional activity (e.g., fusion protein degradation) only when placed at the N-terminus or within an internal position.
[0198] Further improvements to the ecDHFR-derived degron have been made by the present inventors who have identified the shortest active peptide. Conveniently, a shorter sequence allows for the fitting of longer coding sequences within the same AAV vector.
[0199] In the present invention, the degron derived from ecDHFR was fused to the N-terminal of the Intein where it is inactive. After protein transplication, the degron is located within the reconstituted Intein and mediates its degradation. The ecDHFRs of the present invention are WT ecDHFR, mutant DHFR, full-length ecDHFR, and shorter ecDHFR.
[0200] DHFR can be 105 to 159 aa in length, Petition 870260074145, dated 07 / 24 / 2026, page 95 / 259 84 / 192 in which shortening occurs at the C-terminal end ecDHFR derived from wild-type E. coli Nucleotide sequence (623 nt) SEQ ID NO: 27 AtcagectgatcgccgccctggccgtKRactacgtgatcggcatggaKaacgccatgxctggaacttecccgccgacctggcctgg ttcaagaKgaacaccctgaacaagcccgtgatcatggKcagficacacCtgERagagcatcKgCaEEcCcCtgcwEEçaREaaga scat ca tcctgagca gccaficccagcaccgacgaca gggtfia cctggg tRaagagcatfigacRa ggccatcgccgcctgcRgcga cfitgcccgagatcat&Etflatcfigcggcggcagggtfiatcgaficagttcctgcccaagficccafiaagctgtacctgacccacatcg acgccga gEtgga ggRCgaca cccacttccccga ctacflagcccgaceacti^aflagcgtEttc^^ cflcccagaacagccacaEctactgcÍtcgaRatcctgfiagafigafigtga amino acid sequence 159 aa- WT SEQ !□ Na. 28 Ml 15 LI A AL AVDR VIG MEN AM PWNL PA D LAW F KR NTL DKP VI MG RHTW ESI GRP LPG RK N11LSSQP G TD D R VT W VKS VD EA IAACG DV PE IM VIG GG R VY E QF LPKA QK LYLT HID AEV EG DTH F PDY EPDDWES VFS EF HDADAQNSHSYCFEiLERR ecDHFR E.Coli derived.

[0202] Optionally, the promoter sequence includes an enhancer sequence, such as the chimeric IgG globin 0 intron.
[0203] For the purposes of this invention, an EGFP (YP_009062989), ABCA4 and CEP290 coding sequence, which are preferably selected respectively from the sequences included herein, or sequences that encode the same amino acid sequence due to genetic code degeneracy, is functionally linked to a promoter sequence capable of regulating its expression in a mammalian retinal cell, particularly in photoreceptor cells.
[0204] Illustrative polyadenylation signals include, without limitation, the bovine growth hormone (bGHpA) polyadenylation signal, the human beta globin polyadenylation signal or a short synthetic version (68), the SV40 polyadenylation signal or other artificial or naturally occurring polyadenylation signal.
[0205] The present invention provides the use of a nucleotide sequence of a degradation signal in order to decrease the stability of the reconstituted protein. Conveniently, one or more sequences can be repeated in order to retain the maximum effect.
[0206] Suitable degradation signals according to the present invention include: (i) the short degron CL1, a C-terminal destabilizing peptide that shares structural similarities with misfolded proteins and is therefore recognized by the ubiquitination system, (ii) Petition 870260074145, dated 07 / 24 / 2026, page 98 / 259 87 / 192 ubiquitin, whose fusion at the N-terminal of a donor protein mediates both direct protein degradation and degradation via the N-end rule pathway, (iii) the N-terminal degron PB29 which is a 9 amino acid-long peptide that, similarly to degron CL1, is predicted to fold into structures that are recognized by enzymes of the ubiquitination pathway, variant ecDHFR and fragments thereof as described herein and in (69), particularly ecDHFR-derived degron signals carrying point mutations that include three amino acid mutations, R12Y, Y100I and G67S conferring functional activity (e.g., fusion protein degradation) only when placed at the N-terminal or within an internal position.
[0207] Exemplary signs of degradation are described in document WO 2016 / 13932, which is incorporated herein by reference.
[0208] As those skilled in the art can readily appreciate, there may be a number of variant sequences of a protein found in nature, in addition to those variants that can be artificially created by the laboratory specialist. The polynucleotides and polypeptides of the present invention encompass those specifically exemplified herein, as well as any natural variants thereof, as well as any variants that may be artificially created, provided that such variants retain the desired functional activity. Furthermore, within the scope of the present invention are polypeptides that have the same amino acid sequences as a polypeptide exemplified herein, except for Petition 870260074145, dated 07 / 24 / 2026, page 99 / 259 88 / 192 amino acid substitutions, additions, or deletions in the polypeptide sequence, provided that these variant polypeptides retain substantially the same relevant functional activities as the polypeptides specifically exemplified herein. For example, conservative amino acid substitutions within a polypeptide that do not affect the polypeptide's function would fall within the scope of the present invention. Thus, the polypeptides disclosed herein should be understood as including variants and fragments, as discussed above, of the sequences specifically exemplified. The present invention further includes nucleotide sequences encoding the polypeptides disclosed herein. These nucleotide sequences can be easily constructed by those skilled in the art having knowledge of the protein and amino acid sequences presented herein.As would be appreciated by a person skilled in the art, the degeneracy of the genetic code allows the specialist to construct a variety of nucleotide sequences that encode a particular polypeptide or protein. The choice of a particular nucleotide sequence may depend, for example, on the use of codons from a particular expression system or host cell. Polypeptides with amino acid substitutions different from those specifically exemplified in the polypeptides in question are also contemplated within the scope of the present invention. For example, non-natural amino acids may be substituted for the amino acids of a polypeptide of the invention, provided that the polypeptide possesses amino acids. Petition 870260074145, dated 07 / 24 / 2026, pp. 100 / 259 89 / 192 substituted amino acids retain substantially the same activity as the polypeptide in which the amino acids have not been substituted. Examples of unnatural amino acids include, but are not limited to, ornithine, citrulline, hydroxyproline, homoserine, phenylglycine, taurine, iodotyrosine, 2,4-diaminobutyric acid, α-aminoisobutyric acid, 4-aminobutyric acid, 2-aminobutyric acid, γ-aminobutyric acid, ε-aminohexanoic acid, 6-aminohexanoic acid, 2-aminoisobutylic acid, 3-aminopropionic acid, norleucine, norvaline, sarcosine, homocitrulline, cysteic acid, t-butylglycine, t-butylalanine, phenylglycine, cyclohexylalanine, β-alanine, fluoroamino acids, designer amino acids such as β-methyl amino acids, C-methyl amino acids, N-methyl amino acids, and amino acid analogs in general. Unnatural amino acids also include amino acids with derivatized side groups. Furthermore, any of the amino acids in the protein can be of the D (dextrorotatory) or L (levorotatory) form.Amino acids can generally be classified into the following classes: nonpolar, uncharged polar, basic, and acidic. Conservative substitutions, in which a polypeptide with an amino acid from one class is replaced by another amino acid from the same class, fall within the scope of the present invention, provided that the polypeptide with the substitution still retains substantially the same biological activity as a polypeptide that does not have the substitution. Table 4 provides a list of examples of amino acids belonging to each class. Petition 870260074145, dated 07 / 24 / 2026, p. 101 / 259 90 / 192 Table 4. List of examples of amino acids belonging to each class. Amino acid classes Examples of amino acids Nonpolar Ala, Val, Leu, Ile, Pro, Met, Phe, Trp Polar Uncharged Gly, Ser, Thr, Cys, Tyr, Asn Acidic Gln Asp, Glu Basic Lys, Arg, His
[0209] Also within the scope of the present invention are polynucleotides that have the same nucleotide sequences as a polynucleotide exemplified herein, except for substitutions, additions, or deletions of nucleotides in the polynucleotide sequence, provided that such variant polynucleotides retain substantially the same relevant functional activity as the polynucleotides specifically exemplified herein (for example, they encode a protein having the same amino acid sequence or the same functional activity as encoded by the exemplified polynucleotide). Thus, the polynucleotides disclosed herein should be understood as including variants and fragments, as discussed above, of the sequences specifically exemplified.
[0210] The present invention also contemplates those polynucleotide molecules having sequences that are sufficiently homologous to the polynucleotide sequences of the invention so as to permit hybridization with that sequence under strict standard conditions and standard methods (Maniatis, T. et al, 1982). The Petition 870260074145, dated 07 / 24 / 2026, p. 102 / 259 The 91 / 192 polynucleotides described in this document may also be defined in terms of more particular identity and / or similarity ranges with those exemplified in this document. Sequence identity will typically be greater than 60%, preferably greater than 75%, more preferably greater than 80%, even more preferably greater than 90%, and may be greater than 95%. The identity and / or similarity of a sequence may be 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98 or 99% or more compared to a sequence exemplified here. Unless otherwise specified, as used herein, the percentile sequence identity and / or similarity of two sequences can be determined using the Karlin and Altschul (1990) algorithm, modified as in Karlin and Altschul (1993).This algorithm is incorporated into the NBLAST and XBLAST programs of Altschul et al. (1990). BLAST searches can be performed with the NBLAST program, score = 100, word length = 12, to obtain sequences with the desired sequence identity percentage. To obtain gapped alignments for comparison purposes, Gapped BLAST can be used as described in Altschul et al. (1997). When using the BLAST and Gapped BLAST programs, the default parameters of the respective programs (NBLAST and XBLAST) can be used. See the NCBI / N1H website.

[0212] The present invention will now be illustrated by means of non-limiting examples. MATERIALS AND METHODS Generation of AAV Vector Plasmids
[0213] The plasmids used for the production of the AAV vector are derived from pAAV2.1 (36) or pZac (37) plasmids containing the ITRs of AAV serotype 2. The AAV intein plasmids were designed as detailed in Figure 1A and Figure S5. The EGFP protein was cleaved at amino acid (aa) C71. The ABCA4 protein was cleaved at the large cytoplasmic domain GDI (34, 35) at aa C1150 (Set 1), aa Petition 870260074145, dated 07 / 24 / 2026, pp. 165 / 259 154 / 192 S1168 (Set 2) and aa C1090 (Set 3). While aa C1150 (Set 1) and S1168 (Set 2) are within regions that are not associated with a known ABCA4 function, C1090 is included in the ABCA4 nucleotide-binding domain that extends from aa929 to aa1148. All CEP290 splitting points fall within the coiled-coil domains (36): when CEP290 was split into two polypeptides, this occurred at either aa C1076 (Set 1) or S1275 (Set 2-3), when it was split into three polypeptides, this was at aa C929 and C1474 (Set 4) or aa S453 and C1474 (Set 5).
[0214] The inteins included in the plasmids were the DnaE intein from Nostoc punctiforme (Npu) (27, 28), or an intein composed of mutated N- and C-inteins from DnaE of Npu and Synechocystis sp. strain PCC6803 (Ssp), respectively (30), or the DnaB intein from Rhodothermus marinus (Rma) (29). The plasmids used in the study were under the control of the promoters of ubiquitous cytomegalovirus (CMV) (38) and short CMV (39) or the promoters of the human photoreceptor-specific G protein-coupled receptor kinase 1 (GRK1) 40. Plasmids encoding EGFP and CEP290 include the bovine growth hormone polyadenylation signal (bGHpA), while plasmids encoding ABCA4 include the simian virus polyadenylation signal 40 (SV40). Production and characterization of the AAV vector
[0215] The AAV vectors were produced by TIGEM AAV Vector Core by triple transfection of HEK293 cells as previously described (14, 41). No differences were observed. Petition 870260074145, dated 07 / 24 / 2026, pp. 166 / 259 155 / 192 in vector yields between AAV vectors including or excluding intein sequences. Transfection and infection of AAV cells
[0216] HEK293 cells were maintained and transfected using the calcium phosphate method (1 pg of each plasmid / well in a 6-well plate format) as previously described (14). For the experiments described in Figure S9, a plasmid quantity encoding the full-length gene corresponding to the same number of molecules contained in 1 pg of AAV intein plasmids was used. The total amount of DNA transfected in each well was kept equal by adding an encoding plasmid when necessary. HeLa cells used for experiments in Figures 2C and 2D were transfected (1 or 0.5 pg of each plasmid / well in a 24-well plate format) using Lipofectamine LTX (Invitrogen). AAV infections were performed as previously described (14). iPSCs and retinal differentiation culture
[0217] Human induced pluripotent stem cells (iPSCs) were derived from fibroblasts that were cultured from skin biopsies using methods described in (42). The STGD1 cell lines carry the heterozygous variants of the ABCA4 compound c.4892T>C and c.4539+2001G>A, also described in (43), or the heterozygous variants of the compound c.[2919-?_3328+?del;4462T>C] and c.5196+1137G>A. c.[2919-?_3328+?del;4462T>C] is an allele consisting of two variations, c.2919-?3328+? Del constitutes a deletion of exons 20, 21, and 22, as well as unknown segments of introns 19 and 22. This deletion Petition 870260074145, dated 07 / 24 / 2026, pp. 167 / 259 156 / 192 was found in a c / s configuration with c.4462T>C. The iPSCs were maintained in matrigel (#354277, Corning®). Matrigel <®> hESC-Qualified Matrix; Corning, NY) coated with 6-well plates containing mTeSR™ medium (# 85850; stem cell technologies). The cells were passed at approximately 80% confluence using 0.5 mM EDTA (# AM9260G; Ambion) for 2–6 minutes. Retinal differentiation was based on a combination of previously described protocols (44, 45). Briefly, iPSCs were seeded in 96-well V-bottom plates (9,000 cells / well) containing RevitaCell supplement (# A-2644501; Gibco, ThermoFisher) and 1% matrigel to induce aggregate formation. The aggregates were then cultured to generate 3D retinal organoids, as reported in (46). Western blot and ELISA analysis
[0218] Samples (HEK293 cells, retinas, and retinal organoids) were lysed in RIPA buffer to extract EGFP, ABCA4, and CEP290 proteins. The lysis buffers were supplemented with protease inhibitors (complete protease inhibitor cocktail tablets; Roche, Basel, Switzerland) and 1 mM phenylmethylsulfonyl. After lysis, ABCA4 samples were denatured at 37°C for 15 minutes in Laemmli sample buffer IX supplemented with 2 M of urea. The EGFP and CEP290 samples were denatured at °C for 5 minutes in Laemmli sample buffer IX. The lysates were separated by electrophoresis on 12% SDS-polyacrylamide gel (for the EGFP sample) or 6% (for the ABCA4 and CEP290 samples). The antibodies used for immunoblotting are as follows: anti-3xflag (1:1000, A8592; Petition 870260074145, dated 07 / 24 / 2026, pp. 168 / 259 157 / 192 Sigma-Aldrich, Saint Louis, MO, USA) to detect EGFP, ABCA4, and CEP290 proteins; anti-ABCA4 (1:500, LSC87292; LifeSpan BioSciences, Inc., Seattle, USA) to detect ABCA4; anti-Filamin A (1:1000, #4762; Cell Signaling Technology, Danvers, MA, USA); anti-β-Actin (1:1000, NB600-501; Novus Biological LLC, Littleton, CO, USA) to detect Filamine A, β-Actin used as a loading control in in vitro experiments; anti-Dysferlin (1:500, Dysferlin, clone Haml / 7B6, MONX10795; Tebu-bio, Le Perrayen-Yveline, France) to detect Dysferlin used as a loading control in in vivo experiments. The quantification of EGFP, ABCA4, and CEP290 bands detected by Western blot was performed using ImageJ software (free download available at http: / / rsbweb.nih.gov / ijy).
[0219] For the experiments shown in Fig. 21, retinal lysates from both Abca4 - / - mice injected with AAV intein vectors and Abca4 + / control litter mice were lysed in 30 L of lysis buffer, as described above, and 25 or 50 L of lysate, respectively, were used for Western blotting using anti-ABCA4 antibodies (LS-C87292; epitope conservation: 100% for human ABCA4; 86% for murine Abca4). The amounts of ABCA4 in retinal lysates, measured by quantifying band intensity using ImageJ software, were then normalized to the volume of retinal lysate loaded onto the acrylamide gel. For the experiments in Fig. 9, HEK293 cells were treated daily with an increased dose of trimethoprim (T7883, Sigma-Aldrich), as reported in the figure. Petition 870260074145, dated 07 / 24 / 2026, pp. 169 / 259 158 / 192
[0220] ELISA was performed on mouse and pig retinal cells or lysates using the Max Discovery Green Fluorescent Protein ELISA kit (Bioo Scientific Corporation, Austin, TX, USA). Southern blot analysis of rAAV vector DNA.
[0221] DNA was extracted from 1.5 to 6 x 10 <10> Viral particles (measured as GC). To digest unpackaged genomes, the vector solution was incubated with 30 µg of DNase (Roche) in a total volume of 300 ml, containing 50 mM Tris, pH 7.5, and 1 mM MgCl2 for 2 hours at 37°C. The DNase was then inactivated with 50 mM EDTA, followed by incubation at 50°C for 1 hour with proteinase K and a 2.5% / V-laurylsarcosyl solution to lyse the capsids. DNA was extracted twice with phenol-chloroform and precipitated with 2 volumes of 100% ethanol and 10% sodium acetate (3 M) and 1 µg of glycogen (200 g). Alkaline agarose gel electrophoresis was performed as previously described (Sambrook, J., and Russel, DW 2001. Molecular cloning: a laboratory manual. Cold Spring Harbor Laboratory Press. Cold Spring Harbor, New York, USA. 999 pp). The markers were produced by double digestion of pF8-V3 with Smal to produce a 5102 bp band. A specific probe for the HLP promoter was used. Activated partial thromboplastin time (aPTT)
[0222] Nine parts of blood were collected by retro-orbital swab in one part of 0.109 M buffered trisodium citrate (BD, Franklin Lakes, NJ, USA). Blood plasma was isolated by centrifuging the samples at 13,000 rpm for 15 minutes.
[0223] aPTT was measured in Coatron M4 (Teco, Biinde, Petition 870260074145, dated 07 / 24 / 2026, pp. 170 / 259 159 / 192 Germany) using the aPTT program following the manufacturer's manual. Immunoprecipitation analysis and liquid chromatography / mass spectrometry.
[0224] Cells were plated in 100 mm plates (cells / plate lx l07) and transfected in suspension with AAV-EGFP plasmids or ABCA4 intein using the calcium phosphate method (20 pg of each plasmid / plate). Cells were harvested 72 hours after transfection and both EGFP and ABCA4 proteins were immunoprecipitated using M2 anti-flag magnetic beads (M8823; Sigma-Aldrich), according to the manufacturer's instructions. Proteins were eluted from the beads by incubation for 15 minutes in sample buffer supplemented with 4 M urea at 37°C. The proteins were then loaded onto 12% (for EGFP) or 6% (for ABCA4) SDS-polyacrylamide gel electrophoresis. Twenty-six and thirty protein bands (from HEK293 cells transfected 2 and 3 times independently with AAV-EGFP and ABCA4 intein plasmids, respectively) cut after staining with Coomassie Blue were used for protein sequencing (Creative proteomics, Shirley, NY).In summary, 3 gel sheets were used for digestion by each of the following enzymes: Trypsin, Chymotrypsin, Glu-C, Arg-C, Asp-N, and LysN. Pepsin was also used to digest ABCA4. The resulting peptides were identified and quantified using nanoscale liquid chromatography coupled with tandem mass spectrometry analysis (nano LC-MS / MS). The mass spectrometry data obtained were analyzed using PEAKS STUDIO 8.5. The inventors achieved... Petition 870260074145, dated 07 / 24 / 2026, pp. 171 / 259 160 / 192 100% protein sequence coverage for EGFP and ABCA4 proteins. Animal models
[0225] The animals were housed at the TIGEM animal facility (Naples) and kept under a 12-hour light / dark cycle.
[0226] C57BL / 6J mice were acquired from Envigo (Italy). Abca4- / - albino mice were generated by successive crosses and backcrosses with BALB / c mice (homozygous for Rpe65 Leu450) and kept inbred. BXD24 / TyJ-Cep290rd16 / J mice (referred to as rdl6) were imported from Jackson Laboratory (stock JAX # 000031). The rdl6 mouse carries an 897 bp in-frame deletion spanning exons 35-39 (46). Mice were maintained by crossing homozygous females with homozygous males. Hemophilic B6;129S-F8tmlKaz / J mice (referred to as F8tml) were imported from The Jackson Laboratory (JAX stock # 004424). The F8tml mouse has a neomycin resistance cassette that replaces 293 bp of the sequence, including 7 bp at the 3' end of exon 16 and 286 bp at the 5' end of intron 16. The mouse colony was maintained by crossing homozygous females with hemizygous males.
[0227] The Large White female sows (Azienda Agricola Pasotti, Imola, Italy) used in this study were registered as purebred in the LWHerd Book of the National Association of Pig Breeders of Italy and were housed at the Centro di Biotecnologie AORN Antonio Cardarelli (Naples, Italy) and kept under a clear cycle / Petition 870260074145, dated 07 / 24 / 2026, pp. 172 / 259 161 / 192 dark for 12 hours. Subretinal injection of AAV vectors in mice and pigs
[0228] This study was conducted in accordance with the Declaration from the Association for Research in Vision and Ophthalmology regarding the Use of Animals in Ophthalmic and Vision Research and in accordance with the regulations of the Italian Ministry of Health for procedures on animals. All procedures on rats were approved by the Italian Ministry of Health; Department of Public Health, Animal Health, Nutrition and Food Safety on March 6, 2015.
[0229] Subretinal injections in mice and pigs were performed as previously described (e.g., in 14). Mouse eyes were injected with 1 pi or 0.5 pi (for rdl6 pups) of vector solution. AAV2 / 8 doses varied in different mouse experiments, as described in the Results section. Pig eyes were injected with 2 adjacent subretinal blebs of 100 ml of AAV2 / 8 vector solution. The AAV2 / 8 dose was 2 x 1011GC per vector / eye, therefore, co-injection of two AAV vectors resulted in a total dose of 4 x 10 GC / Eye. Histology, Light Microscopy and Fluorescence
[0230] To evaluate EGFP expression in histological sections, retinal organoids, C57BL / 6J mouse eyes, and Large White pig eyes were fixed and sectioned as previously described. EGFP-positive cryosections, mounted with Vectashield with DAPI (Vector Lab Inc., Peterborough, UK), were analyzed under an LSM-700 confocal microscope (Carl Zeiss, Oberkochen, Germany) using excitation Petition 870260074145, dated 07 / 24 / 2026, pp. 173 / 259 162 / 192 and appropriate detection settings acquired at 40x magnification. Due to the prevalence of red-green color blindness, to avoid the presence of red and green together, the colors in the original images were modified in Fig. 14.
[0231] To evaluate the thickness of the outer nuclear layer in rdl6 mice injected with AAV intein vectors. CEP290, the eyes were fixed in 4% paraformaldehyde (PFA) overnight, followed by dehydration in serial ethanols and then embedded in paraffin blocks. Serial sections of rdl6 mice (22h) were cut along the horizontal meridian, progressively distributed onto slides, and stained with hematoxylin and eosin (H&E). The sections were then analyzed under a microscope (Leica Microsystems GmbH; DM5000) and acquired at 20x magnification. For each eye, an image of the temporal side injected from a slice in the central region of the eye was used for analysis. Three ONL thickness measurements were made on each image by an operator masked to the genotype / treatment group using the freehand line tool of ImageJ software. Immunofluorescence analysis
[0232] HeLa cells transfected with ABCA4 intein plasmids or CEP290 AAV were fixed 24 hours after transfection in 4% PFA for 10 minutes. The cells were blocked in blocking buffer (0.05% saponin, 0.5% BSA, 50 mM NH4Cl, 0.02% NaI in PBS, pH 7.2) for 30 minutes and then incubated as follows: - for 1 hour with anti-FLAG M2 antibody (F1804, Sigma) Petition 870260074145, dated 07 / 24 / 2026, pp. 174 / 259 163 / 192 Aldrich) to detect ABCA4 proteins; with anti-VAP-B antibody [produced in the Antonella De Matteis laboratory ((47)], to stain the endoplasmic reticulum and with TGN46 (AHP-499, Serotech) to stain the Trans-Golgi network. After washing in PBS, the cells were incubated with secondary antibodies for 30 min: goat anti-mouse Alexa Fluor 568; goat anti-rabbit Alexa Fluor 488, donkey anti-sheep Alexa Fluor 633 directed against anti-FLAG, -VAP-B and -TGN46 antibodies, respectively. - overnight with anti-FLAG antibody (F7425, Sigma-Aldrich) to detect CEP290 proteins and with anti-acetylated tubulin antibody (T6793, Sigma-Aldrich) to stain microtubules. After washing in PBS, the cells were incubated with appropriate secondary antibodies for one hour: goat anti-rabbit Alexa Fluor 594 and Alexa Fluor 488 donkey anti-mouse, directed against the anti-FLAG and -Ac-Tubulin antibodies, respectively.
[0233] The nuclei were stained with DAPI. Due to the prevalence of red-green color blindness, to avoid the presence of red and green together, the colors of the original images were modified in Fig. 2 CD and Fig. 18.
[0234] The antibodies used for immunofluorescence of human retinal organoids are as follows: anti-human chone arrestin (CAR) (50, 51) (1:10000, 'Luminaire founders' hCAR; gift of Dr. Cheryl M. Craft, Doheny Eye Institute, Los Angeles, CA, USA); anti-Opsin, Red / Green (1:200, AB5405; Merck Millipore, Darmstadt, Germany); anti-Recoverin (1:500, AB5585; Merck Millipore); anti-CRX (A-9, 1:250, sc377138; Santa Cruz Biotechnology, Dallas, Petition 870260074145, dated 07 / 24 / 2026, pp. 175 / 259 164 / 192 Texas, USA); anti-rhodopsin (1D4, 1:200, ab5417, Abeam, Cambridge, MA, USA. Transmission electron microscopy and scanning electron microscopy analyses
[0235] For electron microscopy (EM) analyses, Abca4- / - mice 3 months after subretinal injection of AAV were dark-adapted overnight, and then the eyes were harvested. The eyes were fixed in 0.2% glutaraldehyde (GA)-2% PFA in 0.1 M PHEM buffer pH 6.9 for 18 hours and then rinsed in 0.1 M PHEM buffer. The eyes were then dissected under a light microscope to select the injected temporal area of the eyepieces. This portion of the eyepieces was subsequently embedded in 12% gelatin infused with 2.3 M sucrose. Cryosections (60 nm) were frozen in liquid nitrogen and sectioned using a Leica Ultramicrotome EM FC7 (Leica Microsystems).To avoid bias in assigning data to the various experimental groups, measurements of the area occupied by lipofuscin granules in the retinal pigment epithelium were performed by an operator masked to the genotype / treatment group using iTEM software (Olympus SYS, Hamburg, Germany). The area of each lipofuscin granule in each field was measured in at least 20 different images (areas of 25 pm2) using the 'Free hand polygon' tool of the iTEM software. For scanning electron microscopy (SEM) analysis, retinal organoids were fixed in GA, stained with Os04, dehydrated in ethanol, and dried using a critical point drying procedure. The dried specimens were then mounted on a SEM specimen outline and coated with a... Petition 870260074145, dated 07 / 24 / 2026, pp. 176 / 259 165 / 192 thin layer of gold. The three-dimensional organization of the sample surfaces was analyzed and images were acquired using a JEOL 6700F scanning electron microscope (JEOL Ltd., Tokyo, Japan).
[0236] For ultrastructure analysis, retinal organoids were fixed overnight with a mixture of 2% PFA and 1% GA in 0.2 M PHEM buffer, pH 7.3. After fixation, the specimens were subsequently fixed as previously described. They were then dehydrated, embedded in epoxy resin, and polymerized at 60°C for 72 hours. Thin serial sections of 60 nm were cut using a Leica EM UC7 microtome.
[0237] EM images were acquired using a FEI Tecnai-12 electron microscope equipped with a VELETTA CCD digital camera (FEI, Eindhoven, Netherlands). Electrophysiological recordings and spectral-domain optical coherence tomography
[0238] Functional and morphological analyses were performed as described above (14). Pupillary light response
[0239] Pupillary light responses of rdl6 mice were recorded in the dark using the TRC-50IX retinal camera connected to a NikonDlH digital camera with a charge-coupled device (Topcon Biomedical Systems, Oakland, NJ). Mice were exposed to 10 lux light stimuli for approximately 10 seconds, and one image per eye was acquired using IMAGEnet software (Topcon Biomedical Systems). For each eye, pupil diameter was normalized to eye diameter (from the temporal side to Petition 870260074145, dated 07 / 24 / 2026, pp. 177 / 259 166 / 192 (nasal). Statistical analysis
[0240] One-way ANOVA (parametric test) or Kruskal-Wallis rank-sum test (non-parametric test) were performed to determine whether there were statistically significant differences between two or more groups of an independent variable in a dependent variable. The P-values are as follows: ELISA assay for EGFP protein quantification in vitro (Kruskal-Wallis p = 0.006036), in mouse retina (ANOVA p = 0.00585) and in pig retina (Kruskal-Wallis p = 0.009005); Figure 5A (p ANOVA = 0.00585); Figure 5B (p Kruskal-Wallis = 5.547E-5); Figure 5C (p ANOVA = 5.81E-10); ERG analyses (p ANOVA or p Kruskal-Wallis > 0.05 in all luminances analyzed for the amplitudes of the a and b waves); OCT analysis in Fig. 14 (p ANOVA = 0.52 for ABCA4 and p ANOVA = 0.965 for CEP290). The statistically significant differences between the groups determined with multiple pairwise comparisons between the group means are as follows: ELISA assay for quantification of EGFP protein in vitro (single AAV versus double AAV = 0.012; AAV intein versus double AAV = 0.012; single AAV versus AAV intein = 0.222), in mouse retina (single AAV versus double AAV = 0.0044; AAV intein versus double AAV = 0.3754; single AAV versus AAV intein = 0.0561) and in pig retina (single AAV versus double AAV = 0.012; Figure 5A: + / + versus - / - AAV inteina = 0.4530; + / + versus - / - = 0.0002; Figure 5B: wild type versus rdl6 AAV inteina = 0.00131; Figure 5C: type Petition 870260074145, dated 07 / 24 / 2026, pp. 178 / 259 167 / 192 wild type versus rdl6 AAV internal IE-07; wild type versus rdl6 negative <IE-06. EXAMPLES Example 1. AAV-EGFP protein reconstitutes the full-length protein in vitro.
[0241] The present inventors tested the efficiency of intein-mediated protein trans-splicing in the retina; two AAV vectors were generated, each encoding the N- or C-terminal half of the EGFP reporter protein fused to the N- and C-terminal halves of the Nostoc punctiform split-intein DnaE [Npu Fig. 1A], respectively. The EGFP protein was spliced at amino acid (aa) C71. Each AAV vector included appropriate regulatory elements (i.e., the bovine growth hormone (bGHpA) polyadenylation promoter and signal) and a triple marker (3xflag) to allow detection of both halves as well as the reconstituted full-length EGFP protein (Fig. 1A).
[0242] AAV-EGFP DnaE intein plasmids were used to transfect human embryonic kidney cells 293 (HEK293) and evaluate the production of single N- and C-terminal halves, as well as full-length EGFP protein. EGFP fluorescence, comparable to that observed in cells transfected with a single AAV plasmid encoding full-length EGFP, was detected in cells co-transfected with AAV-EGFP intein plasmids, but not with the single AAV-EGFP N- and C-terminal intein plasmids, as shown in Fig. 12. The presence of transdivided EGFP protein of the expected size (~28 kDa) along with DnaE intein (~17 kDa) split from the mature protein was confirmed. Petition 870260074145, dated 07 / 24 / 2026, pp. 179 / 259 168 / 192 by Western blot (WB) analysis of HEK293 cell lysates only after co-transfection of both AAV-EGFP intein plasmids, as shown in Fig. IB. Furthermore, quantification of band intensity showed that the amounts of EGFP protein from the AAV intein plasmids were 76 ± 37% (n = 3 independent experiments) of those observed from a single AAV plasmid. To define the accuracy of protein reconstitution, EGFP was immunopurified from HEK293 cells transfected with the AAV-EGFP intein plasmids and liquid chromatography-mass spectrometry (LC-MS) analysis was performed to define its protein sequence. The 3539 peptides obtained from the proteolytic digestion of this sample, 7 of which included the split point (Table 5), covered the entire protein and confirmed that the amino acid sequence of EGFP reconstituted by AAV plasmid-containing proteins corresponds precisely to that of wild-type EGFP.

AAV-EGFP internals are more efficient than dual AAV vectors in vitro.
[0243] To confirm the reconstitution of the EGFP protein from the AAV intein vectors, HEK293 cells were infected with AAV2 / 2-CMV-EGFP DnaE intein or with single and double AAV vectors that included the same expression cassette. Multiplicity of infection (moi), 5 x 104 genome copies (GC) / cell of each vector, meaning a similar dose among the 3 systems, assuming that the double vectors undergo complete recombination of DNA or protein. In order to precisely quantify the amounts of EGFP, cell lysates were harvested seventy-two hours after infection. EGFP expression was evaluated by WB and enzyme-linked immunosorbent assay (ELISA): EGFP expression obtained with AAV intein vectors was approximately half that achieved with a single AAV (single AAV = 0.735 ± 0.2 ng EGFP / pg total lysate, n = 5 independent experiments; AAV intein = 0.403 ± 0.04 ng EGFP / pg total lysate, n = 5). Petition 870260074145, dated 07 / 24 / 2026, pp. 181 / 259 170 / 192 independent experiments) and 10 times greater than that obtained with double AAV vectors, as shown in Fig. 1C (double AAV = 0.046 ± 0.01 ng EGFP / pg total lysate, n = 5 independent experiments). Furthermore, the intensity of full-length EGFP relative to that of excised intein was quantified by WB; its relative abundance was found to be 1:0.2 (n = 6 independent experiments, Fig. 13A). Example 3. Subretinal administration of AAV-EGFP integer vectors results in efficient reconstitution of full-length proteins in the mouse and pig retina.
[0244] To investigate whether trans-splicing mediated by AAV intein reconstitutes full-length protein expression in the retina, 4-week-old C57BL / 6J mice were injected subretinally with AAV2 / 8-CMV-EGFP Dna E intein vectors (dose of each vector / eye: 5.8 x 109GC). Eyes were harvested 1 month later and analyzed by microscopy. EGFP fluorescence was detected in all eyes in the retinal pigment epithelium and, most importantly, in the photoreceptors (Fig. ID). To compare the expression of the AAV intein transgene to that of single and double AAV in photoreceptors, AAV2 / 8 vectors encoding EGFP under the control of the photoreceptor-specific human G protein-coupled receptor kinase 1 (GRK1) promoter were subretinally injected into one-week-old 4-C57BL / 6J mice (dose of each vector / eye: 5c10 <l>9 GC). Eyes were collected 1 month after injection and analyzed by fluorescence microscopy, ELISA, or WB.
[0245] EGFP fluorescence was detected in the layer Petition 870260074145, dated 07 / 24 / 2026, pp. 182 / 259 171 / 192 of photoreceptor cells in eyes injected with all vector sets, as seen in Fig. IE. Precise quantification of EGFP protein amounts by ELISA confirmed that AAV intein reconstituted EGFP protein less efficiently than a single AAV and approximately 3 times more efficiently than double AAV (single AAV = 8.41 ± 2.48 ng EGFP / retina, n = 5 eyes; AAV intein = 3.72 ± 0.85 ng EGFP / retina, n = 7 eyes; double AAV = 1.38 ± 0.43 ng EGFP / retina, n = 7 eyes). The relative amounts of full-length EGFP to excised intein after quantification of WB band intensities were 1:3 (n = 14 eyes analyzed, Fig. 13B).
[0246] The inventors then evaluated the efficiency of AAV intein vectors in photoreceptor transduction in the porcine retina, which is an excellent preclinical model for evaluating viral vector transduction due to its size and architecture ((48). Thus, Large White pigs were injected subretinally with single and double AAV2 / 8-GRK1-EGFP vectors (dose of each vector / eye: 2 x 1011GC, delivered through two adjacent subretinal blebs). The eyes were harvested 1 month after injection and analyzed by either fluorescence microscopy, ELISA, or WB. Notably, the reconstitution of EGFP protein mediated by AAV intein in the photoreceptor cell layer was greater than that mediated by double AAV and indistinguishable from vectors. Single AAVs, as assessed by EGFP fluorescence (Fig. IF). Precise quantification of EGFP in retinal lysates confirmed that AAVs reconstitute the protein in amounts similar to those achieved with a single AAV. Petition 870260074145, dated 07 / 24 / 2026, pp. 183 / 259 172 / 192 AAV is approximately 3 times greater than those obtained with double AAV vectors (single AV AAV = 247.5 ± 45.1 ng EGFP / retina, n = 5 eyes; intein AAV = 227.0 ± 15.7 ng EGFP / retina, n = 5 eyes; double AAV = 82.3 ± 9.6 ng EGFP / retina, n = 5 eyes). The relative amount of full-length EGFP to excised intein after quantification of WB band intensities was 1:2 (n = 8 eyes, Fig. 13C). Example 4. Full-length EGFP is reconstituted by AAV-mediated protein trans-splicing in 3D human retinal organoids.
[0247] As an additional representative preclinical model of the human retina, the inventors generated 3D retinal organoids ((49, 50)) from human induced pluripotent stem cells (iPSCs). Six-month-old organoids (Fig. 14A) contained cells stained with mature photoreceptor markers, as shown in Fig. 14B; the organoids were successfully transduced by AAV2 vectors with a photoreceptor-specific promoter, namely AAV2 / 2 CMV EGFP and AAV2 / 2 IRBP DsRed vectors, as shown in Fig. 14C by fluorescence analysis. (Fig. 14D) and electron microscopies (Fig. 14E-F) show the presence of outer segment buttons of photoreceptors. Nine-month-old 3D human retinal organoids incubated for 30 days with AAV-GRK1-EGFP intein vectors (dose of each vector / organoid: 1 x 1012GC) show EGFP fluorescence (Fig. 1G). WB analysis of retinal organoid lysates (Fig.15) confirms the expression of full-length EGFP which was approximately 5 times more abundant than excised intein after band intensity quantification (n = 4. Petition 870260074145, dated 07 / 24 / 2026, pp. 184 / 259 173 / 192 organoids). Example 5. Trans-splicing mediated by the intein of large proteins (identification of ideal ABCA4 and CEP90 cleavage points is necessary for efficient AAV intein-mediated protein trans-splicing)
[0248] To test whether protein trans-splicing can be developed as a mechanism for reconstituting large therapeutic proteins, the inventors developed the AAV-ABCA4 and -CEP290 intein vectors. ABCA4 and CEP290 were split into two (AAV I, AAV II) or three (AAV I, AAV II, AAV III) fragments whose coding sequences were cloned separately into single AAV vectors, fused with the coding sequences of the split N- and C-terminal inteins as shown in Fig. 16. The AAV intein vectors included the ubiquitous short CMV [(shCMV), for all sets] or the GRK1 promoter (set 1 for ABCA4 and set 5 for CEP290).The splicing points for each protein were selected taking into account the amino acid residue requirements at the junction points for efficient protein trans-splicing 18, 51), as well as the preservation of the integrity of critical protein domains, which should favor proper folding and stability of each independent polypeptide and, therefore, of the final reconstituted protein. Additional split inteins were also considered. CEP290 sets in which the protein was split into 3 polypeptides (sets 4 and 5, Fig. 16B) were generated to allow the inclusion of the marmot hepatitis virus Post-transcriptional Regulatory Element [WPRE, (52)] to increase transgene expression. Para. Petition 870260074145, dated 07 / 24 / 2026, pp. 185 / 259 174 / 192 to avoid unwanted trans-splicing between AAV I and AAV III, which could reduce the amount of total length protein generated, sets 4 and 5 included two different split inteins at the two cleavage junctions, specifically DnaB intein from Rhodothermus marinus and any type or a mutated DnaE intein that the inventors show do not exhibit cross-reactivity (Fig. 17).
[0249] The inventors compared the ability of each set of AAV interen plasmids to reconstitute ABCA4 and CEP290 after transfection of HEK293 cells. The analysis of WB of cell lysates 72 hours after transfection showed that full-length ABCA4 and CEP290 proteins of the expected size (~250 kDa and ~290 kDa, respectively) were reconstituted from each set of AAV intein plasmids, although with variable efficiency (Fig. 2A-B). Sets 1 and 5 were considered the most efficient for the reconstitution of ABCA4 and CEP290 proteins, respectively, and therefore used in all subsequent experiments.
[0250] To determine the accuracy of protein reconstitution, the inventors immunopurified ABCA4 from HEK293 cells transfected with set 1 and performed LC-MS analysis to define its protein sequence. The 3108 peptides obtained from the proteolytic digestion of this sample, 22 of which included the split point (Table 6), covered the entire protein and confirmed that the amino acid sequence of ABCA4 reconstituted by AAV plasmids corresponds precisely to that of wild-type ABCA4. The amino acid sequence of reconstituted ABCA4 Petition 870260074145, dated 07 / 24 / 2026, pp. 186 / 259 The 175 / 192 sequence of AAV intein corresponds to that of wild-type ABCA4. Alignment was performed between the wild-type ABCA4 sequence and the peptides identified in the liquid chromatography-mass spectrometry analysis of ABCA4 reconstituted from AAV inteins. Table 6.

[0251] The inventors then evaluated the intracellular localization of the protein products of the different intein-containing plasmids, comparing them with the localization of the full-length protein. The full-length ABCA4 is known to localize in the endoplasmic reticulum (ER) when expressed in cultured cell lines (53, 54). The two ABCA4 polypeptides from set 1 were found to co-localize in the ER, while no colocalization was found in the Trans-Golgi network (Fig. 20). A similar localization was observed in cells co-transfected with both AAV intein plasmids, as well as in cells transfected with a plasmid encoding the full-length ABCA4 protein, thus confirming the predominant localization in the ER of ABCA4 exogenously expressed in cell lines).
[0252] Regarding CEP290, it has been reported that the full-length protein shows a mixed distribution pattern with a predominantly speckled pattern and a fibrillar pattern. Petition 870260074145, dated 07 / 24 / 2026, pp. 188 / 259 177 / 192 smaller (55). Dissection of the domains responsible for the subcellular targeting of CEP290 showed that the N-terminal domain (aa 1-362) directs the protein to vesicular structures thanks to its ability to interact with membranes, while a region near the C-terminal of CEP290, encompassing much of the myosin tail homology domain of the protein, mediates microtubule binding (aa 580-2479) and when expressed as a truncated form has a prominent fibrillar distribution coinciding with acetylated tubulin (Ac-Tub). According to Drivas et al.Immunofluorescence analysis in HeLa cells transfected with AAV I, II, or III intein plasmids individually or cotransfected with AAV I + II, AAV I + III, and AAV II + III showed that AAV I and AAV II products have a predominantly speckled pattern, while AAV III (encompassing the myosin tail homology domain of the protein) shows a fibrillar pattern and is the only one to completely co-localize to Ac-tub (Fig. 2D). Thus, AAV I + II products have a predominantly speckled pattern, while those of AAV I + III and AAV II + III have a combined fibrillar and speckled microtubule pattern. Cells cotransfected with the three AAV CEP290 intein plasmids showed a predominantly speckled signal partially aligned along the microtubules that is comparable to the signal observed in cells transfected with a plasmid encoding the full-length CEP290 protein (Fig. 2D and Fig. 18).
[0253] The present inventors then compared the amount of protein obtained with the best set of Petition 870260074145, dated 07 / 24 / 2026, pp. 189 / 259 178 / 192 AAV-ABCA4 and -CEP290 intein plasmids were compared with those obtained from a single AAV plasmid encoding the corresponding full-length protein. For this purpose, HEK293 cells were transfected with the same equimolar amounts of the single AAV intein plasmid, and 72 hours after transfection, cell lysates were analyzed by WB (Fig. 19). Quantification of band intensity showed that the expression of ABCA4 and CEP290 from AAV intein plasmids was 61 ± 4% (n = 3 independent experiments) and 58 ± 4% (n = 3 independent experiments) of that observed with the corresponding single AAV plasmids, respectively. Example 6. AAV intraocular vectors mediate the expression of large therapeutic proteins in vitro and in the retina.
[0254] The inventors compared the efficiency of large protein reconstitution mediated by AAV intein with that of dual AAV vectors both in vitro and in mouse and pig retinas. HEK293 cells were infected with dual AAV2 / 2 vectors or inteins encoding ABCA4 (set 1) or CEP290 (set 5) (moi: 5x 10 <l>4 GC / cell of each vector) and cell lysates were analyzed 72 hours later by WB. As shown in Figures 3A and 3B, the AAV-ABCA4 and -CEP290 intein vectors mediated the reconstitution of large proteins more efficiently than the double AAV vectors. As expected, in addition to full-length proteins, shorter polypeptides derived from either of the AAV intein vectors (in the case of ABCA4 and CEP290) or from trans-splicing occurring between AAV II and AAV III (in the case of CEP290) were observed (Fig. 3A and 3B). Petition 870260074145, dated 07 / 24 / 2026, pp. 190 / 259 179 / 192 3B).
[0255] In addition, 4-week-old wild-type mice were subretinally injected with AAVGRK1-ABCA4 or -CEP290 intein (sets 1 and 5, respectively) compared with double vectors (dose of each vector / eye ABCA4: 3.3 x 109GC, dose of each vector / eye CEP290: 1.1 x 109GC). Animals were sacrificed 47 weeks after injection and protein expression in retinal lysates was assessed by WB. Full-length proteins were detected in 10 / 11 (91%) of eyes injected with AAV-ABCA4 intein (Fig. 4A and 20) and in 5 / 10 (50%) of eyes injected with AAV-CEP290 intein (Fig. 4B). On the other hand, full-length protein expression was evident in 5 / 9 (56%) and in 0 / 5 eyes injected with the dual AAV vectors ABCA4 and CEP290, respectively.Similar to what was observed in vitro, polypeptides derived from single AAV integer vectors (in the case of ABCA4 and CEP290) and from transsplicing occurring between AAV II and AAV III (in the case of CEP290) were detected (Figs. 4A and 4B).
[0256] To investigate the efficiency of AAV-mediated protein reconstitution in relation to endogenous ABCA4, 1-4 month old Abca4- / - mice were injected subretinally with AAVGRK1-ABCA4 intein vectors (set 1) (dose of each ABCA4 vector / eye: 5.5 x 109GC). One month later, ABCA4 expression in retinal lysates from unaffected Abca4- / - mice injected with AAV intein was analyzed by WB using an antibody that recognizes human and murine ABCA4 (Fig. 21). AAV ABCA4 intein expression was 8.6 ± 1.3% of endogenous ABCA4. Petition 870260074145, dated 07 / 24 / 2026, pp. 191 / 259 180 / 192
[0257] To confirm the efficient reconstitution of large proteins in clinically relevant pig retinas, Large White pigs were injected subretinally with AAV2 / 8-GRK1-ABCA4 intein (set 1) or dual vectors (dose of each vector / eye: 2x 1011GC, delivered through two adjacent subretinal blebs) and protein expression after 1 month of injection was analyzed by WB. Notably, AAV intein was found to reconstitute full-length ABCA4 protein more efficiently than dual AAV vectors (Fig. 4C).
[0258] Lastly, human retinal organoids from iPSCs of healthy individuals or STGD1 patients at 121 days of culture [when photoreceptor maturation begins (20)] were infected with AAV2 / 2-GRK1-ABCA...
