Cross-reference to related applications

[0001] This application claims the benefit of U.S. Provisional Application Serial No. 63 / 584,695, filed September 22, 2023, and U.S. Provisional Application Serial No. 63 / 603,581, filed November 28, 2023, each of which is incorporated herein by reference in its entirety.

[0002] sequence list This application contains references to amino acid sequences and / or nucleic acid sequences, which were submitted with this application as a sequence listing XML file entitled "823037_sequencelisting.xml", with a file size of 36,864 bytes, created on September 20, 2024. According to 37 CFR... 1.52(e)(5), the above sequence list is incorporated in full by reference. Technical Field

[0003] This disclosure generally relates to novel signal peptides, and more specifically to novel secretory signal peptides for guiding the export of encoded proteins from cells. Background Technology

[0004] Recent scientific discoveries have highlighted the numerous therapeutic applications of mRNA due to its modular nature and ability to provide customizable "instructions" to produce functional proteins. Clinical studies continue to confirm its beneficial efficacy, further emphasizing its potential as a next-generation genetic drug, where scientists are only beginning to scratch the surface of its potential applications. To date, most research has focused on enhancing the intracellular expression of encoded peptides. However, little attention has been paid to the post-translational control of the encoded protein and its targeted localization and / or secretion in vivo.

[0005] Within the cell, various unique pathways and processes exist that allow proteins to shuttle to various organelles and to be exported to the extracellular space via excretion pathways. However, in order to utilize these transport systems, the mRNA encoding each protein must also contain a metaphorical transport marker called a signal peptide (SP) upstream of the protein sequence. The design of novel SPs for therapeutic mRNAs can greatly benefit the delivery, localization, and clearance of the encoded therapeutic proteins. This disclosure addresses these and other needs.

[0029] Before describing the compositions and methods of the present invention, it should be understood that the scope of this disclosure is not limited to the specific processes, compositions, or methodologies described herein, as these are subject to variation. It should also be understood that the terminology used herein is for the purpose of describing a particular version or embodiment only and is not intended to limit the scope of this disclosure. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. It should be further understood that any methods and materials similar to or equivalent to those described and materials herein can be used in the practice or testing of embodiments of the methods and systems disclosed herein, and such equivalents are within the scope of this disclosure.

[0030] definition The following explanations of terms and methods are provided to better describe this disclosure and to guide those skilled in the art in practicing this disclosure.

[0031] As used herein, unless the context explicitly indicates otherwise, "comprising" means "including" and the singular forms "a," "an," or "the" include a plural number of indicators. For example, references to "comprising a therapeutic agent" include one or more such therapeutic agents. Unless the context explicitly indicates otherwise, the term "or" refers to a single element among the stated alternative elements. For example, the phrase "A or B" means A alone or B alone. The phrase "A, B, or a combination thereof" means A alone, B alone, or a combination of A and B. Similarly, "one or more of A and B" means A, B, or a combination of both A and B. The phrase "A and B" means a combination of A and B. Furthermore, the various elements, features, and steps discussed herein, as well as other known equivalents of each such element, feature, or step, can be mixed and matched by those skilled in the art to perform methods according to the principles described herein. Among the various elements, features, and steps, some will be specifically included in a particular instance, while others will be specifically excluded from a particular instance.

[0032] In some instances, figures used to describe and claim certain embodiments, representing the amount of an ingredient, properties such as molecular weight, reaction conditions, etc., should be understood to be modified in some cases by the terms “about” or “approximately.” For example, “about” or “approximately” can indicate a variation of + / - 10%, + / - 5%, or + / - 1% in the value it describes. Thus, in some embodiments, the numerical parameters set forth herein are approximate values that can vary depending on the desired characteristics of a particular embodiment. Furthermore, unless the context indicates otherwise, when the phrase enumerates “about x to y,” the term “about” modifies both x and y and can be used interchangeably with the phrase “about x to about y.”

[0033] As used herein, the terms “transformation” and “transfection” are intended to refer to a variety of art-recognized techniques for introducing exogenous nucleic acids into host cells, including calcium phosphate or calcium chloride coprecipitation, DEAE-dextran-mediated transfection, lipid transfection (e.g., using commercially available reagents such as, for example, LIPOFECTIN® (Invitrogen Corp., San Diego, CA), LIPOFECTAMINE® (Invitrogen), FUGENE® (Roche Applied Science, Basel, Switzerland), JETPEI™ (Polyplus-transfection Inc., New York, NY), EFFECTENE® (Qiagen, Valencia, CA), DREAMFECT™ (OZ Biosciences, France)), or electroporation (e.g., in vivo electroporation). Suitable methods for transforming or transfecting host cells can be found in Sambrook et al. ( Molecular Cloning: A Laboratory Manual. (2nd edition, Cold Spring Harbor Laboratory, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY, 1989) and other laboratory manuals.

[0034] Methods and materials for non-viral delivery of nucleic acids to cells also include biolistics, virions, liposomes, lipid nanoparticles, immunoliposomes, polycationic or lipid-nucleic acid conjugates, naked DNA, artificial viral particles, and drug-enhanced DNA uptake. Lipid transfection is described in U.S. Patent Nos. 5,049,386, 4,946,787, and 4,897,355, and lipid transfection reagents are commercially available (e.g., TRANSFECTAM™ and LIPOFECTIN™). Cationic and neutral lipids suitable for effective receptor recognition of polynucleotides in lipid transfection include those disclosed in WO 91 / 17424 and WO 91 / 16024.

[0035] The chemical composition of peptides will be described herein by a series of single-letter abbreviations of amino acids, or “amino acid sequence” or “sequence”, which are conventional and known to those skilled in the art. Although a reference sequence will be explicitly disclosed, it may be modified in any aspect and embodiment to include conserved amino acid substitutions, as well as variants and fragments, while maintaining the characteristics and functionality of the reference sequence.

[0036] As used herein, a "payload protein" or "protein of interest" refers to a protein that will be produced by the host cell and subsequently exported from the cell due to the presence of a secreted signal peptide. During export, all, some, or none of the novel signal peptides may fuse with the payload protein. Optionally, the payload protein, still partially or completely attached to the novel signal peptide, may be further processed, for example, to remove any remaining novel signal peptide. The payload protein can be any protein known or yet to be known, such as enzymes, enzyme inhibitors, growth factors, hormones, antibodies, antigens, vaccines, therapeutics, or any combination thereof. More specific examples are given below.

[0037] As used herein, the terms “fused” or “linked” when referring to proteins with different domains or heterologous sequences mean that the protein domains are parts of the same peptide chain linked together by peptide bonds or other covalent bonds. Domains or segments may be directly linked or fused to each other, or another domain or peptide sequence may be between two domains or sequences, and such sequences will still be considered fused or linked together. In some embodiments, the various domains or proteins provided herein are directly linked or fused to each other or with adapter sequences, such as the glycine / serine sequence described herein that links two domains together.

[0038] As used herein, “identity” refers to the subunit sequence identity between two polymeric molecules, such as two nucleic acid or amino acid molecules, or between two polynucleotide or polypeptide molecules. Two amino acid sequences are identical when they have the same residue at the same position; for example, if each of two polypeptide molecules has an arginine residue at that position, then they are identical at that position. The degree of identity, or similarity, between two amino acid or two nucleic acid sequences having the same residue at the same position in an alignment is usually expressed as a percentage. Identity between two amino acid or two nucleic acid sequences is a direct function of the number of matching or identical positions; for example, if half of the positions in two sequences are identical, then the two sequences have 50% identity; if 90% of the positions (e.g., 9 out of 10) match or are identical, then the two amino acid sequences have 90% identity.

[0039] "Substantially identical" means a polypeptide or nucleic acid molecule that exhibits at least 50% identity with a reference amino acid sequence (e.g., any of the amino acid sequences described herein) or nucleic acid sequence (e.g., any of the nucleic acid sequences described herein). In some embodiments, this sequence has at least 60%, 80%, or 85%, or 90%, 95%, or even 99% identity with the sequence used for comparison at the amino acid level or nucleic acid level. Other percentages of identity with a particular sequence are described herein.

[0040] Sequence identity can be measured / determined using sequence analysis software (e.g., sequence analysis packages from the Genetics Computing Group of the University of Wisconsin Biotechnology Center, 1710 University Avenue, Madison, Wis. 53705, including BLAST, BESTFIT, GAP, BLAST-2, ALIGN, MEGALIGN (DNASTAR), CLUSTALW, CLUSTALOMEGA, MUSCLE, or PILEUP / PRETTYBOX programs). Such software matches identical or similar sequences by specifying degrees of homology for various substitutions, deletions, and / or other modifications. Conserved substitutions typically include substitutions within the following groups: glycine, alanine; valine, isoleucine, leucine; aspartic acid, glutamic acid, asparagine, glutamine; serine, threonine; lysine, arginine; and phenylalanine, tyrosine. In exemplary methods for determining the degree of identity, a BLAST program can be used, where a probability score between e3 and e100 indicates closely related sequences. In some embodiments, sequence identity is determined using BLAST with default settings. In some implementations, Clustal Omega is used to determine sequence identity.

[0041] For the purposes of the embodiments provided herein, compositions comprising various proteins may be included, in some cases, containing amino acid sequences that have sequence identity with the amino acid sequences disclosed herein. Therefore, in some embodiments, depending on the specific sequence, the degree of sequence identity with the SEQ ID NO disclosed herein is preferably greater than 50% (e.g., 60%, 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more). In addition to these percentages, other percentages of identity are also provided herein. Identity between peptides can be determined using an affine gap search with parameters vacancy opening penalty – 12 and vacancy extension penalty = 1, as implemented in the MPSRCH (Oxford Molecular) program.

[0042] Compared to the disclosed protein sequence, these proteins may include one or more (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc.) conserved amino acid substitutions, i.e., one amino acid is replaced by another amino acid with a related side chain. Genetically encoded amino acids are generally classified into four families: (1) acidic, i.e., aspartic acid and glutamic acid; (2) basic, i.e., lysine, arginine, and histidine; (3) nonpolar, i.e., alanine, valine, leucine, isoleucine, proline, phenylalanine, methionine, and tryptophan; and (4) nonpolar, i.e., glycine, asparagine, glutamine, cysteine, serine, threonine, and tyrosine. Phenylalanine, tryptophan, and tyrosine are sometimes collectively classified as aromatic amino acids. Generally, substitution of a single amino acid within these families does not have a significant impact on biological activity. Compared to the disclosed protein sequence, proteins may have one or more (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc.) single amino acid deletions. In addition to the disclosed protein sequence, the protein may also include one or more (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc.) insertions (e.g., each of 1, 2, 3, 4, or 5 amino acids).

[0043] "Encoding" refers to the inherent property of a specific nucleotide sequence in a polynucleotide (such as a gene, cDNA, or mRNA) to serve as a template for the synthesis of other polymers and macromolecules in biological processes. These polymers and macromolecules have defined nucleotide sequences (i.e., rRNA, tRNA, and mRNA) or defined amino acid sequences, and the resulting biological properties. Therefore, if the transcription and translation of the mRNA corresponding to a gene produces a protein in a cell or other biological system, then that gene encodes a protein. Both the coding strand, whose nucleotide sequence is identical to the mRNA sequence and is typically provided in sequence listings, and the non-coding strand, which serves as a template for transcription of a gene or cDNA, can be referred to as encoding the protein or other product of that gene or cDNA.

[0044] As used in this article, the following abbreviations for common nucleic acid bases are used: "A" refers to adenosine, "C" refers to cytosine, "G" refers to guanosine, "T" refers to thymidine, and "U" refers to uridine.

[0045] Unless otherwise specified, "nucleotide sequence encoding an amino acid sequence" includes all nucleotide sequences that are degenerate versions of each other and encode the same amino acid sequence. A phrase encoding a protein or RNA nucleotide sequence may also include introns, provided that the nucleotide sequence encoding that protein may contain introns in some versions.

[0046] The term "oligonucleotide" generally refers to short polynucleotides. It should be understood that when a nucleotide sequence is represented by a DNA sequence (i.e., A, T, C, G), this also provides a corresponding RNA sequence (i.e., A, U, C, G), where "U" replaces "T".

[0047] As used herein, the term "polynucleotide" is defined as a nucleotide chain. Furthermore, nucleic acids are polymers of nucleotides. Therefore, as used herein, the terms "nucleic acid" or "nucleic acid molecule" and "polynucleotide" are interchangeable. As used herein, polynucleotides include, but are not limited to, all nucleic acid sequences obtained by any method available in the art and by synthetic means, including but not limited to recombinant methods, i.e., cloning nucleic acid sequences from recombinant libraries or cell genomes using cloning techniques such as PCR.

[0048] As used herein, the terms “peptide,” “polypeptide,” and “protein” are used interchangeably and refer to compounds comprising a plurality of amino acid residues covalently linked by peptide bonds. As used herein, the term refers to short chains, which are also commonly referred to in the art as, for example, peptides, oligopeptides, and oligomers; and long chains, which are commonly referred to in the art as proteins, which exist in many types. “Polypeptide” includes, for example, biologically active fragments, substantially homologous polypeptides, oligopeptides, homodimers, heterodimers, variants of polypeptides, modified polypeptides, derivatives, analogs, fusion proteins, etc. Polypeptides include natural peptides, recombinant peptides, synthetic peptides, or combinations thereof.

[0049] As used herein, unless otherwise stated, "antibody fragment" or "antigen-binding fragment" means an antigen-binding fragment of an antibody, i.e., an antibody fragment that retains the ability to specifically bind to the antigen to which the full-length antibody is bound, such as a fragment retaining one or more CDR regions. Examples of antibody-binding fragments include, but are not limited to, Fab, Fab', F(ab')2, and Fv fragments; bivalent antibodies; linear antibodies; single-chain antibody molecules, such as sc-Fv; nanobodies (single-domain antibodies); and multispecific antibodies formed from antibody fragments.

[0050] The "Fab fragment" contains a light chain and a heavy chain of C. H 1. Variable region. The heavy chain of a Fab molecule cannot form a disulfide bond with another heavy chain molecule.

[0051] The “Fc” region contains two C-cells containing antibodies. H 2 and C H 3. Heavy chain segments of structural domains. Two heavy chain segments are connected by two or more disulfide bonds and by C... H The hydrophobic interactions of the three structural domains are combined.

[0052] A “Fab fragment” contains a portion or fragment of a light chain and a heavy chain, and contains V H Domain and C H 1. Structural domains and C H 1 and C H The region between the two domains allows interchain disulfide bonds to form between the two heavy chains of the two Fab' segments to form the F(ab')2 molecule.

[0053] The “F(ab')2 fragment” contains two light chains and two chains containing C. H 1 and C H The heavy chains, which constitute a portion of the constant region between the two heavy chains, allow interchain disulfide bonds to form between them. Therefore, the F(ab')2 segment consists of two Fab' segments bonded together by disulfide bonds between the two heavy chains.

[0054] The “Fv region” contains variable regions from both the heavy and light chains, but lacks constant regions.

[0055] The term "single-chain Fv" or "scFv" antibody refers to a V antibody containing an antibody. H and V L Antibody fragments containing domains, wherein these domains are present within a single polypeptide chain. Generally, Fv polypeptides also contain V... H With V LA peptide linker between the domains allows scFv to form the structure required for antigen binding. For a review of scFv, see Pluckthun (1994). Volume 113, edited by Rosenburg and Moore, Springer-Verlag, New York, pp. 269-315. See also International Patent Application Publication No. WO 88 / 01649 and U.S. Patent Nos. 4,946,778 and 5,260,203.

[0056] Antibody molecules can be monospecific (e.g., monovalent or bivalent), bispecific (e.g., bivalent, trivalent, tetravalent, pentavalent, or hexavalent), trispecific (e.g., trivalent, tetravalent, pentavalent, or hexavalent), or have a higher order of specificity (e.g., tetraspecific) and / or a higher order of valence than hexavalent. Antibody molecules can contain functional fragments of both the light chain variable region and the heavy chain variable region, or the heavy and light chains can be fused together to form a single polypeptide.

[0057] As used herein, the terms “comprising” (and any form of inclusion, such as “comprise”, “comprises”, and “comprised”), “having” (and any form of having, such as “have” and “has”), “including” (and any form of including, such as “includes” and “include”), or “containing” (and any form of containing, such as “contains” and “contain”) are inclusive or open-ended and do not exclude additional, unlisted elements or method steps. Any step or composition using the transitional phrase “comprise” or “comprising” can also be described using the transitional phrase “consisting of” or “consists”.

[0058] As used herein, the term “contact” means bringing together two elements of an in vitro or in vivo system. For example, “contacting” a virus or vector described herein with an individual or patient or cell includes administering the virus to an individual or patient (such as a human), and, for example, introducing a compound into a sample containing a cell preparation or a purified preparation containing such cells.

[0059] As used herein, the interchangeable terms “individual” or “subject” or “patient” mean any animal, including mammals such as mice, rats, other rodents, rabbits, dogs, cats, pigs, cattle, sheep, horses, or primates such as humans. In some embodiments, the subject is a human. A “subject in need” means a subject who has been identified as requiring treatment for a condition to be treated and is being treated with the specific intent to treat such condition. A condition can be any condition described herein, for example.

[0060] The compositions disclosed herein can be administered to a subject in a variety of ways by administering the composition to the subject. As used herein, administering or administering means providing or providing the composition to a subject. As used herein, oral administration means delivery of the active agent through the mouth. As used herein, topical administration means delivery of the active agent to the body surface, such as the skin, mucous membranes (e.g., nasal membranes, vaginal membranes, buccal membranes, etc.).

[0061] "Disease" is a health condition in which an animal is unable to maintain homeostasis, and if the disease is not treated, the animal's health continues to deteriorate. In contrast, an animal's "symptom" is a health condition in which the animal is able to maintain homeostasis, but the animal's health is not as good as it would be in the absence of the symptom. A symptom, if left untreated, does not necessarily lead to further deterioration of the animal's health.

[0062] The terms "effective amount" or "therapeutic effective amount" are used interchangeably herein and refer to the amount of a compound, formulation, material, or composition as described herein that effectively achieves a particular biological outcome or provides a therapeutic or preventative benefit. Such outcomes may include, but are not limited to, the amount of immune cell activation induced at a detectable level when administered to a mammal, compared to immune cell activation detected in the absence of the composition. Immune responses can be readily assessed using a wide range of methods recognized in the art. Those skilled in the art will understand that variations in the amount of the composition administered herein can be readily determined based on a number of factors, such as the disease or symptom being treated, the age and health status and physical condition of the mammal being treated, the severity of the disease, and the specific compound administered.

[0063] Scope: Throughout this disclosure, various aspects of the embodiments may be presented in the form of scope. It should be understood that the description in scope form is merely for convenience and brevity and should not be construed as an immutable limitation. Therefore, the description of scope should be considered as having specifically disclosed all possible sub-scopes and individual numerical values within that scope. For example, a description of a scope such as 1 to 6 should be considered as having specifically disclosed sub-scopes such as 1 to 3, 1 to 4, 1 to 5, 2 to 4, 2 to 6, 3 to 6, etc., and individual numbers within that scope, such as 1, 2, 2.7, 3, 4, 5, 5.3, and 6. This applies regardless of the width of the scope. Unless otherwise explicitly stated to the contrary, the disclosed scope also includes the endpoints of the scope.

[0064] Novel signal peptides Unbound by any particular theory, it has been found that the embodiments provided herein demonstrate that novel signal peptides can direct the secretion of payload proteins, as described herein, from cells. The payload proteins may or may not naturally contain a signal peptide that directs the protein to a specific cellular compartment, such as a signal peptide secreted from cells. Therefore, the novel signal peptides provided can direct the enhanced expression and secretion of proteins that naturally contain secretory signal peptides, or can direct the secretion of payload proteins (e.g., therapeutic proteins) that do not naturally contain secretory signal peptides from cells.
