AI Technical Summary

Technical Problem

Existing recombinant Pichinde virus vectors face challenges in maintaining genetic stability and consistent transgene expression, as well as the ability to infect and amplify in host cells effectively, while avoiding recombination and promoting long-lasting expression.

Method used

The Pichinde virus genome is engineered with ORFs positioned differently than their wild-type locations, utilizing 5' and 3' untranslated regions (UTRs) to control gene expression, and creating three-segmented virus particles that are replication-competent but unable to produce infectious progeny in non-complementing cells, ensuring stable and prolonged transgene expression.

Benefits of technology

This approach enhances genetic stability and ensures consistent transgene expression, allowing the virus to infect and amplify in host cells without producing further infectious particles, thus providing a reliable vector for immunotherapy and vaccine applications.

[0003] 1. Introduction This application relates to a recombinant human ovarian genome having a rearrangement of its open reading frame ("ORF") within the genome. In particular, the present specification relates to a modified Pichinde virus. A viral genome segment, the Pichinde virus genome segment being a virus The ORF has been engineered to carry an ORF in a position other than the wild-type position of that ORF. The document provides one L segment and two S segments, or two L segments and The present invention relates to a three-segmented Pichinde virus particle, which comprises one S segment and one H segment. The Pichinde virus described herein can be used in vaccines and / or or may be suitable for the treatment of disease and / or for use in immunotherapy. [Background technology]

[0004] 2. Background 2.1 General background and genomic organization of Pichinde virus Pichinde virus was isolated from Oryzomys albigularis (rice rat) in Colombia. (McLay et al., 2014, Journal of General Virology, 95: 1 Pichinde viruses are non-pathogenic and generally do not cause disease in humans. Serological evidence indicates that seroprevalence is high even in native populations. (Trapido et al., 1971, Am J Trop Med Hyg, 20: 631-6 41) The Arenaviridae family includes the Lassa fever virus (LASV) and lymphocytic venous Old World (OW) arenaviruses such as cholangiocarcinoma meningitis virus (LCMV), and Pichinde virus and Junin virus-like New World (NW) arenaviruses are classified into two groups (Buchmeier 2001, "Arenaviridae: The Viruses and Their Replication" Viruses and Their Replication), Fields Virology Vol 2, 1635-1668). Its genome consists of two strands of negative-sense single-stranded RNA. It consists of four segments (Figure 1A). (McLay et al., 2014, Journal of General Virology, 95: 1-15). Each segment encodes two viral genes in opposite orientations. The S segment encodes the viral glycoprotein (GP) and nucleoprotein (NP). The long segment (L segment) encodes RNA-dependent RNA polymerase (RdRp; L protein) and matrix protein Z (protein Z), a RING finger protein The two genes on each segment are separated by a non-coding intergenic region (IGR). The IGR is flanked by 5' and 3' untranslated regions (UTRs). It has been shown that the ribosome-specific ribosome-binding domain (RiB) forms a ribosome-specific ...nuclease (RiB) domain and is involved in the structure-dependent termination of viral mRNA transcription (Pinschewe (R. et al., 2005, J Virol 79(7): 4519-4526). The terminal nucleotides of the UTRs are highly homologous. These panhandle structures are essential for transcription and replication. It is known to function as a viral promoter for Their analysis by gene expression reveals sequence- and structure-dependent structures that cannot tolerate even minor sequence changes. (Perez and de la Torre, 2003, Virol 77(2): 1184-1194).

[0005] 2.2 Reverse genetic systems The isolated and purified RNA of negative-strand viruses such as Pichinde virus is expressed as mRNA. They are not capable of functioning directly, i.e., cannot be translated when introduced into a cell. As a result, transfection of cells with viral RNA results in the generation of infectious viral particles. Conversion of negative-strand RNA virus infection from cDNA to permissive cells in culture To make a viral particle, the viral RNA segment(s) undergoes transcription and replication. The gene must be trans-complemented with the minimum necessary factors. With the help of the viral signaling system, the viral symbionts involved in transcription, replication and formation of viral particles are The gene-acting elements and trans-acting factors could finally be analyzed (Lee et al., 2003). , 2000, J Virol 74(8): 3470-3477; Lee et al., 2002, J Virol 76(12): 6393-6 397; Perez and de la Torre, 2003, J Virol 77(2): 1184-1194; Pinschewer et al., 2003, J Virol 77(6): 3882-3887; Pinschewer et al., 2005, J Virol 79(7): 4519-4526). Such a reverse genetics system successfully rescued Pichinde virus. The method has been developed to successfully demonstrate the i, 1171: E65-E74; Lan et al., 2009, Journal of Virology, 83 (13): 6357-6362 (See ).

[0006] 2.3 Recombinant Pichinde expressing the gene of interest The creation of recombinant negative-strand RNA viruses expressing foreign genes of interest has long been pursued. Various strategies have been published for other viruses (Garcia-Sastre et al. , 1994, J Virol 68(10): 6254-6261; Percy et al., 1994, J Virol 68(7): 448 6-4492; Flick and Hobom, 1999, Virology 262(1): 93-103; Machado et al. , 2003, Virology 313(1): 235-249). Live Pichinde virus-based vectors have been published. (Dhanwani et al., 2015, Journal of Virology 90:2551-2560; International Patent Publication No. Publication number WO 2016 / 048949. A three-segmented Pichinde virus has been published (Dhanwa Ni et al., 2015, Journal of Virology 90:2551-2560; International Patent Application Publication No. WO 2015 / 023636 16 / 048949). In a three-segment virus published by Dhanwani in 2015, NP Both the and GP are retained in their native positions within the S segment, and therefore the They were expressed under their native promoters.

[0007] 2.4 Replication-deficient arenaviruses Infectious arenavirus particles have the ability to amplify and express their genetic material in infected cells. Normal cells that contain the genome but are not genetically engineered will generate additional progeny. However, it is possible to engineer an infectious, replication-deficient arenavirus such that it cannot replicate in the host (i.e., infectious replication-deficient arenaviruses). particles) (International Publication No. WO 2009 / 083210 A1 and International Publication No. WO 2014 / 140301 A1).

Alternatively, the L and S segments of the virus together with the NP and L proteins Intracellular synthesis of menthol is achieved by the L and S segments of two separate plasmids, one on each side. This can be done using an expression cassette with pol-I and pol-II promoters reading into the cDNA. can.

[0184] In one embodiment, the Pichinde virus genome segment is regulated by a promoter. Typically, RNA polymerase I-driven expression cassettes and RNA polymerase II-driven cassettes are used. Alternatively, a T7 bacteriophage RNA polymerase-driven cassette can be used. In one embodiment, a plasmid encoding the Pichinde virus genome segment The (multiple) may be the same, i.e., the genomic sequence and the trans-acting factors are the same as one The transcription can be initiated from the mide by a promoter.

However, when generated from cDNA, the infectious, replication-defective Pichinde virus provided herein can be propagated in complementing cells, which, due to modifications of their genome, are replication-deficient. These are cells that provide functionality excluded from the Pichimde virus (e.g., GP protein). When the ORF encoding the GP tag is deleted or functionally inactivated, complementing cells (providing protein).

[0191] One or more of the ORFs in the Pichinde virus vector have been deleted or are functionally inactive. The deletion of the glycoprotein GP is used as an example. The target gene is provided in trans to the deleted viral gene(s), e.g., in this example, GP. Such complementing cell lines, hereafter referred to as C cells, can be generated and propagated in BHK-2 1. Express the viral gene(s) of interest in a cell line such as HEK 293, VERO, or other cell line.

[0193] The plasmids are of two types: i) the minimal transactivator of Pichinde virus; Two plasmids, called TF-plasmids for intracellular expression in C cells, e.g. in this case from the NP and L proteins of the Pichinde virus; and ii) from the Pichinde virus The vector genome segment, e.g., the segment having the engineered modification, is then cultured in a C cell. The TF-plasmid can be a plasmid called GS-plasmid for intracellular expression. The NP and L proteins of each Pichinde virus vector were expressed in mammalian cells. An expression cassette suitable for protein expression, typically a mammalian promoter such as the CMV or EF1α promoter. Either of these can be expressed as polyadenylation under the control of an animal polymerase II promoter. The GS-plasmid is a small ( It expresses the small (S) and large (L) genome segments. It is usually driven by polymerase I. A T7 bacteriophage RNA polymerase (T7-) driven expression cassette or The latter can be used to preferentially catalyze the 3' end ribozyme for processing of the primary transcript. When using a T7-based system, T Expression of T7 was constructed in a similar manner to the TF-plasmid, and an additional expression plasmid providing T7 was used. This must be brought about by including the In one embodiment, the cells are constructed to further express T7 in a stable manner. The plasmid and the GS plasmid can be the same, i.e., the genomic sequence and trans-acting factors are , T7, polI, and polII promoters can be used to transcribe from one plasmid.

[0194] For the recovery of the Pichinde virus vector, the following procedure can be used. Day 1: Incubate C cells, typically at 80% confluence in a 6-well plate, with two TF-plasmids and two In one embodiment, a mixture of TF and GS plasmids is transfected. The plasmids can be the same, i.e. the genomic sequence and trans-acting factors are T7, polI, and polII promoters from one plasmid. Commonly used protocols such as calcium, liposome-based protocols or electroporation Any of the strategies used in the study can be used.

[0195] After 3-5 days: Collect the culture supernatant (Pichindane virus vector preparation), aliquot it, and aliquot it before use. Store at 4°C, -20°C, or -80°C depending on how long the Chinde virus vector will be stored. The infectious titer of the Pichinde virus vector preparation was then determined by immunofluorescence assay for C cells. Alternatively, the transfected cells and supernatants were analyzed by a focus assay. Subculture the cells into a larger container (e.g., T75 tissue culture flask) 3–5 days after transfection. Culture supernatants may be collected up to 5 days after passaging.

[0198] ii) Alternatively, a lower MOI can be used and individual cell clones can be isolated from their viral load. The Pichinde virus vector can then be used to select for the level of expression of the antigen. Due to the non-lytic nature of the method, individual clones can be multiplied indefinitely. The antigen is then added either to the culture supernatant or to the cells themselves, depending on the nature of the antigen produced. However, the present invention is not limited to these two strategies. The antigen is expressed using an infectious, replication-deficient Pichinde virus as a vector. Other methods of driving the current may be considered.

However, when made from cDNA, the infectious, replication-defective vectors provided herein can be The genovirus can be propagated in complementation cells, which are capable of adapting to modifications of the genome. Thus, it is a cell that provides functionality that is excluded from the replication-deficient Pichinde virus (e.g., G Complementation when the ORF encoding the P protein is deleted or functionally inactivated cells provide the GP protein).

[0214] Removal or functional inactivation of one or more of the ORFs in the Pichinde virus vector (herein glycoproteins) For example, the Pichinde virus vector contains deleted viral genes. The gene(s), e.g., in this example, GP, can be produced and propagated in cells that provide the gene(s) in trans. Such complementing cell lines, hereafter referred to as C cells, may include BHK-21, HEK 293, VERO, or other The target viral gene (multiple genes) is transfected into a mammalian cell line such as HIV-1 (here, BHK-21 is used as an example).

This synthetic cDNA was used to express mouse polymerase I (pol-I). (Pinschewer et al., J Virol. 2003 Mar;77(6):3882-7) and pol-I-PIC-mi This resulted in niS-GFP (Figure 3).

[0313] We introduced noncoding mutations to delete both BbsI restriction sites in Pichinde virus Modification of the NP ORF of strain Munchique CoAn4763 isolate P18 (Genbank accession number EF529747.1) A mutant cDNA was synthesized. This synthetic ODNA was appropriately flanked by BbsI and EcoRI and NheI restriction sites. RF (NPΔBbsI; SEQ ID NO: 6) was introduced into the polymerase II (pol-II) expression vector pCAGGS, and the eukaryotic This resulted in pC-PIC-NP-Bbs (Figure 3) for the expression of Pichinde NP protein in cells.

[0314] We digested NPΔBbsI with BbsI and cloned the BbsI-mutated NP ORF into the pol-I-PIC-mi It was inserted into the niS-GFP backbone, thereby replacing the GFP ORF with the NP ORF for cloning purposes. The 3'UTR-NP-IGR portion of the Pichinde virus S segment cDNA with all restriction sites removed. The resulting plasmid expresses PIC-NP-Bsm (SEQ ID NO: 7) under the control of pol-I. The resulting pol-I-PIC-NP-Bsm plasmid (Figure 3) was used to express the resulting recombinant Pichinde virus S segment. For expression in eukaryotic cells, the 5'U is inserted by seamlessly replacing the BsmBI site. It is designed to accommodate a transgene of interest to be inserted between the TR and the IGR.

[0315] We introduced non-coding mutations to delete both BbsI restriction sites in a Pichinde virus strain. Modification of the GP ORF of Munchique CoAn4763 isolate P18 (Genbank accession number EF529747.1) DNA was synthesized. As with NPΔBbsI, this synthetic ORF was introduced into the pol-I-PIC-miniS-GFP backbone. thereby replacing the GFP ORF with the GP ORF and providing all restriction sites for cloning purposes. Seamless reconstruction of the 3'UTR-GP-IGR portion of the Pichinde virus S segment cDNA with deleted nucleotides The resulting pol-I-PIC-GP-Bsm plasmid expressing PIC-GP-Bsm (SEQ ID NO: 8) (Figure 3) For the expression of recombinant Pichinde virus S segment in eukaryotic cells, a BsmBI site was inserted. The transgene of interest to be introduced between the 5'UTR and IGR by seamless replacement Designed to accommodate children.

[0316] We then inserted the following genes and transgenes into pol-I-PIC-NP-Bsm: The plasmids containing the following genes were inserted: 1. GFP, 2. sP1AGM, and 3. PichindeGP. The vectors were pol-I-PIC-NP-GFP (expressing PIC-NP-GFP, also known as S-NP / GFP; SEQ ID NO: 11) and and pol-I-PIC-NP-sP1AGM (expressing PIC-NP-sP1AGM; SEQ ID NO: 12) and pol-I-PIC-S (expressing PIC-S; SEQ ID NO: 13).

[0317] 5.1.4 DNA transfection of cells and rescue of recombinant viruses 3. Stably Transfected to Express Lymphocytic Choriomeningitis Virus Glycoprotein The BHK-21 cells (BHK-GP cells, Flatz et al. Nat Med. 2010 Mar;16(3):339-45) 5 x 10 cells in a 6-well plate 5 Cells were seeded at a density of 100 cells / well and incubated for 24 hours as described by the manufacturer. We used Lipofectamine (approximately 3 μl / μg DNA; Invitrogen) according to the instructions provided with the kit. The recombinant two-segment virus was transfected from plasmid DNA in different amounts. For total rescue of viral vectors, two minimal viral transactivators, NP and L from pol-II-driven plasmids (0.8 μg pC-PIC-NP-Bbs, 1.4 μg pC-PIC-L-Bsm). The cells were delivered to the cells and co-transfected with 1 μg of pol-I-PIC-L and 0.8 μg of pol-I-PIC-S. In the case of rescue of a three-segment r3PIC consisting of an L segment and two S segments, the μg of both pol-I driven S segments were included in the transfection mix. 72 hours after transfection, the cells and supernatant were transferred to a 75 cm2 tissue culture flask and Supernatants were collected 48–96 h after incubation. Viral infectivity was assessed in a focus-forming assay. The virus was passaged 48 times in normal BHK-21 cells for further amplification (infectivity at 48 hours). The viral titer of the virus stock thus obtained was determined by focusing This was again determined by formation assay.

The viruses were generated by infecting either 100 or 1500 cells with 100% ethanol and the supernatants were collected 48 hours after infection. The proliferation curve of BHK021 cells was performed in vitro in a T75 cell culture flask format. The cells are 5 × 10 6 The cells were seeded at a density of 100 cells / flask and after 24 hours, the cells were inoculated into 5 ml of a 0.01 moi culture. Incubate with the virus inoculum for 90 min on a rocker plate at 37°C and 5% CO2. Fresh medium was added and the cells were incubated at 37°C / 5% CO2. At given time points (usually 24, 48, and 72 hours), supernatants were harvested and assayed for focus formation. The virus titer was analyzed.

[0319] 5.1.6 Focus formation assay The titer of Pichinde virus was then determined by focus-forming assay. If not, 293-T cells or 3T3 cells were used for focus formation assays. 3 × 10 4 Cells were seeded in 96-well plates at a density of 100 cells / well and incubated with 100 mM NaCl, 0.5% CO2, and 0.5% ethanol. After 2–4 h of incubation at 37°C, the 100 μl of 3.17-fold serial dilutions of the virus were mixed with the Then, 80 μl of viscous medium (2% methylcellulose in 2× supplemented DMEM) was added per well. After 48 hours at 37°C, the supernatant was The cells were flicked off and lysed by adding 100 μl of methanol for 20 min at room temperature. The cells were then fixed (all subsequent steps were performed at room temperature). The cells were then plated in 100 μl / well of BSS / 1% Tris The cells were permeabilized with ton X-100 (Merck Millipore) for 20 min, followed by blocking with PBS / 5% FCS for 60 min. For anti-NP staining, rat anti-pichin de NP monoclonal antibody was used as the primary staining antibody. The plates were washed three times with tap water and the secondary HRP -Add goat anti-rat IgG at a dilution of 1:100 in PBS / 2.5% FCS and incubate for 1 hour. The plate was washed again three times with tap water. Color reaction (0.5 g / l DAB (Sigma D-5637), 0.5 g / l nickel ammonium sulfate in PBS / 0.015% H2O2) was added and the reaction was incubated for 10 min before dilution with water. The stained foci were counted and the final titer was calculated according to the dilution factor.

[0320] 5.1.7 Mouse BALB / c mice were purchased from Charles River Laboratories and were specific pathogen-free for the experiments. All animal experiments were performed under specific pathogen-free (SPF) conditions at the University of Basel. The infections were carried out in accordance with the Swiss legislation and with the permission of the respective responsible cantonal authorities. , 1 × 10 per mouse 5 The treatment was performed intravenously at a dose of FFU.

[0323] 5.2 Results 5.2.1 Trisegmented Pichinde virus-based vectors with artificial genome organization design The genome of wild-type Pichinde virus contains two negative polarity single-stranded RNA segments (one The 5' untranslated region (5'UTR) and Allows seamless insertion of a transgene of choice between the intergenic regions (IGRs) of duplicated S segments Based on the cassette system that enables the generation of replicable three-segment peptides with artificial genome organization, Polymerase-I / II-driven for r3PIC-art virus vectors (Figures 1B, 1C, and 1D) A cDNA rescue system was designed to completely remove the transgene upon insertion, thus obtaining Insertion of a gene into the arenavirus S segment using a BsmBI site that is not present in the recombinant virus Seamless insertion of the gene (i.e., the remaining nucleotide sequence derived from molecular cloning) A molecular cloning strategy for See Pinschewer et al., Proc Natl Acad Sci U S A. 2003 Jun 24;100(13):7895-90 0 and in supporting FIG. 4. The BbsI enzyme is described in Flick et al., J Vir For seamless cloning, as reviewed in ol. 2001 Feb;75(4):1643-55, These Pichinde virus-based r3PIC-art genomes were used in the same way to identify human It consists of the wild-type Pichinde virus L segment with a randomly duplicated S segment, and the 3'UTR Under the control of the nucleoprotein (NP) or glycoprotein (GP), i.e., between the 3'UTR and the IGR, This allows for the insertion of a transgene into each S segment. i.e., each transgene is inserted into two S segments, leaving one position for each S segment. The vectors could be inserted between the 5'UTR and IGR of each of the vectors.

[0324] 5.2.2 Rescue from three-segment recombinant virus vectors with artificial genome configuration Isolated infectious GFP-expressing virus To generate the three-segment recombinant Pichinde virus, we used the We synthesized multiple plasmids as described above. We synthesized the following combinations of plasmids: (A) S segment minigenome: pC-PIC-L-Bsm, pC-PIC-NP-Bbs, pol-I-PIC-miniS-GFP ; (B) L segment minigenome: pC-PIC-L-Bsm, pC-PIC-NP-Bbs, pol-I-PIC-L-GFP-Bsm ; (C)r3PIC-GFP art : pC-PIC-L-Bsm, pC-PIC-NP-Bbs, pol-I-PIC-L, pol-I-PIC-NP-GF P, pol-I-PIC-GP-GFP; (D)rPIC wt : pC-PIC-L-Bsm, pC-PIC-NP-Bbs, pol-I-PIC-L, pol-I-PIC-S was used to transfect BHK-21 cells.

[0325] We observed GFP expression 48 hours after transfection of the S and L segment minigenomes. Heading (Figure 4, Plasmid combinations A and B outlined above), active in gene expression Pichinde virus S and L segment analytes as functional ribonucleoproteins (RNPs) We documented the intracellular reconstruction of the log. Similarly, r3PIC-GFP art The purpose of the production of Transfection C demonstrated GFP-positive cells 48 hours after transfection, whereas , rPIC wt The plasmid combination D for constructing the vector showed green fluorescence as expected. At 168 hours after transfection, GFP-positive cells were found to be S and L segment myoglobin-dependent. In the two genome transfection, most of the genes disappeared, but in the r3PIC-GFP art have Infectious GFP-expressing viruses were reconstituted from the cDNA and expressed in the cells. It was shown that it spread during cultivation.

[0326] 5.2.3 Recombinant three-segment viruses grow to lower titers than wild-type Pichinde virus rPIC wt and r3PIC-GFP art Comparative growth curves were performed with the viruses obtained using the above methods (Figure 2). Supernatants from transfections C and D in Section 5.2.2 were pooled and serially replicated in parallel in BHK-21 cells. For both viruses, peak infectivity was reached after 48 h. However, r3PIC-GFP art The latter is essentially rPIC wt This was lower than that of the three segments. r3PIC-GFP art showed that the two-segmented wild-type parent virus was attenuated compared to its parent virus. Ta.

[0327] 5.2.4 Recombinant r3PIC expressing sP1AGM induces rapid, potent, and versatile P1A-specific CD8+ T cell responses Derive the answer. r3PIC for vaccination purposes art To test the utility of vector delivery technology, we , r3PIC-GFP art r3PIC-sP1AGM, which has a similar genomic organization to (Fig. 1C). art Vaccine Vectors We created r3PIC-GFP (Figure 1D). art Similar to that outlined above for procedure, but instead of the plasmids pol-I-PIC-NP-GFP and pol-I-PIC-GP-GFP, Virus expressing sP1AGM using pol-I-PIC-NP-sP1AGM and pol-I-PIC-GP-sP1AGM (r3PIC-sP1AGM art We created a BALB / c mouse lineage that was injected intravenously with 10e5 focus-forming monoclonal antibodies. r3PIC-sP1AGM (FFU) art After immunization with 100 μg / mL of ...

A distinct population of IgG1 expression was observed in the peripheral blood of mice that was not present in the blood of non-immunized mice (Figure 5A). and 5B). These observations suggest that r3PIC-art-based viral vectors are highly immunogenic and , have demonstrated to be a promising tool for immunotherapy and vaccination.

[0328] 5.2.5 When tested at early passages after rescue from cDNA, A recombinant three-segment construct designed to express certain glycoprotein and nucleoprotein genes. and expressing its glycoprotein under the control of the 3' untranslated region (UTR) promoter. Both recombinant three-segment viruses engineered to inhibit wild-type Pichindewi It grows to lower titers than We expressed the GFP gene under the control of the 5' and 3' UTR promoters, respectively, i.e., S-GP / GFPnat (sequence No. 15) and an artificial duplicate of S-NP / GFP (also known as PIC-NP-GFP; SEQ ID NO: 11). The glycoprotein (GP) and We generated a three-segmented Pichinde virus expressing the ribosomal and nucleoprotein (NP) genes (Figure 6). This r3PIC-GFP nat The virus is a three-segment r3PIC-GFP art The virus is outlined above. was created by a procedure similar to that shown. nat The outline is shown in Fig. 6. When grown in culture in BHK-21 cells (multiplicity of infection = 0.01 , collected at 48 hours), r3PIC-GFP nat is effectively rPIC wt Lower titer, r3PIC-GFP art About The low titers reached were similar to those observed with the 100% HO cells cultured in the same wells (Figure 7; symbols represent individual parallel cell culture wells). (Titers for 300-fold increase in 300-fold increase in 1 ... C-GFP nat was shown to be attenuated compared to its bisegmented wild-type parent virus.

[0329] 5.2.6 Recombinant three-segment virus with artificial genomic organization is expressed during persistent infection of immunodeficient mice. Virus (r3PIC-GFP art ) maintained transgenic GFP expression and expressed wild-type Pichin Deu Illus (rPIC wt ) maintains a consistently lower viral titer in the blood, while its glycoprotein and and a three-segment fusion protein designed to express nuclear protein genes in their respective natural locations. Virus (r3PIC-GFP nat ) eventually lost GFP expression and wt equivalent to animals infected with The blood viral load is reached. We developed a triple-deficient mouse model of type I and type II interferon receptors and RAG1 (AGR mouse). Grob et al., 1999, "Effects of attenuated pseudorabies virus on the control of systemic outbreaks Role of the individual interferon system and specific immunity in mice al interferon systems and specific immunity in mice in controlling systemic diss 'emission of attenuated pseudorabies virus infection)', J Virol, 4748-54). On day 0, 10e5 focus forming units ("FFU") of r3PIC-GFP art , r3PIC-GFP nat , or rPIC wt We infected mice intravenously (iv) with one of the following viruses: Blood was collected on days 56, 77, 98, 120, and 147, and viral infectivity was determined by FFU assay. In these assays, we detected the Pichinde virus nucleoprotein (NP FFU; Fig. 8). or r3PIC-GFP nat and r3PIC-GFP art detected the viral GFP transgene (GFP FFU; Fig. 9 ). From these values, we calculated the NP:GFP FFU ratio for each animal and each time point (Figure 10). .

[0330] r3PIC-GFP for the first 21 days postinfection natand r3PIC-GFP art Total infectivity (NP FFU assay) (as determined by I) persisted at similar levels in the blood of AGR mice and wt infection This was approximately 10-fold lower than in the control (Figure 8). However, from day 28 onwards, nat infection Potency is determined by NP FFU assay, as well as rPIC wt reached a level that was indistinguishable from In contrast, r3PIC-GFP art NP FFU titers were higher for rPICwt than for rPICwt throughout the 147-day observation period. The levels remained approximately 10-fold lower than those observed in the control group (Figure 8).

[0331] In addition to detecting the viral structural protein NP to determine total viral infectivity (Figure 8) We used r3PIC-GFP nat - and r3PIC-GFP art -Infectivity expressed in the blood of infected AGR mice To evaluate the transgene expressing GFP, an FFU assay was performed (GFP FFU, FIG. 9). In striking contrast to the NP FFU titers (Figure 8), r3PIC-GFP nat GFP FFU titers in -infected AGR mice After the 28th day, the levels of r3PIC-GFP decreased, and after the 120th day, the levels were undetectable (Figure 9). a rt - This was in contrast to the almost constant GFP FFU titers in the blood of infected mice (Figure 9). By calculating the “P:GFP FFU ratio” (Figure 10), we found that r3PIC-GFP art -In infected mice It was determined that virtually all of the infectivity (NP FFU) also expressed the GFP transgene. This was supported by a NP:GFP FFU ratio in the range of 1 throughout the 147-day observation period (Figure 10). In striking contrast, r3PIC-GFP nat - The NP:GFP FFU ratio in the blood of infected mice The number of storms started around 1 on the 28th, but by the 28th, it had reached several hundred and more (Figure 10). Populations of virions circulating in the blood of r3PIC-GFPnat-infected mice on day 28 and later Within the 100 or fewer cells, only one in 100 still expressed the GFP transgene, and the GFP-expressing infectivity , which eventually dropped below detectable levels. art A.G. GFP transgene expression was maintained through 147 days of persistent infection in R mice.

[0332] 5.2.7 r3PIC-GFP art -Viruses recovered from the serum of infected mice were r3PIC wt -An infected animal? r3PIC-GFP reached titers similar to those of viruses isolated from nat -Compared to those from infected animals and maintained attenuated To evaluate the growth characteristics of viruses circulating in the serum of persistently infected AGR mice, we Viremic serum collected 147 days after infection of BHK-21 cells was passaged and NP FFU antigen was obtained 48 hours later. Viral infectivity was determined by r3PIC-GFP assay. nat -Grown in serum from infected mice The virus was rPIC wt Reaching IFF titers similar to or higher than those from virus-infected animals (Figure 11; symbols indicate virus titers from individual mouse sera; error bars indicate mean (Mean values ​​are shown + / - SD). In contrast, r3PIC-GFP art-obtained after passage of sera from infected mice Viral titers were substantially lower than in any of the previously described groups (Figure 11).

[0333] From these viruses that were passaged for 48 h, we further analyzed cell culture growth. Four were randomly selected from each group for the experiment shown in Figure 11 (direct measurement of infectivity from serum). Unlike the previous experiment (passages), this experiment (Figure 12) was normalized for input infectivity, as a potential confounding factor in the assessment of viral titers achieved in culture. Different amounts of input infectivity were excluded. Therefore, we standardized the BHK-21 cells. The cells were infected at a multiplicity of infection of 0.01, and the virus titer was determined 48 hours later (Figure 12; symbols indicate Titers from virus derived from individual mouse sera are shown; error bars represent the mean + / - SD). Similar to the differences in titers found after direct ex vivo passaging from serum, r3PIC-GF P nat -The virus was derived from rPIC wt - Reached a titer at least equivalent to that of the source virus. In contrast, in vivo passaged r3PIC-GFP art The titers achieved by the virus derived from was substantially lower than that of the other two groups.

[0334] This is r3PIC-GFP nat - The virus recovered from the serum of infected animals is already attenuated. However, r3PIC-GFP art -The virus circulating in the blood of infected mice was rPIC wt -Origin of Wii These results suggest that the virus was still clearly attenuated compared to the AGR mice. Through experiments in rPIC wtViremia lower than r3PIC-GFP art Viremia (section 5.2.6 ), and also rPICs when re-amplified from blood in cell culture. wt Potency Lower r3PIC-GFP art Judging from the titer, r3PIC-GFP art In vivo duplication in mice The attenuation was maintained throughout the 147-day production period.

[0335] 5.2.8 r3PIC-GFP nat Unlike the above, the recombinant three-segment virus has an artificial genome structure. Rus(r3PIC-GFP art ) did not recombine its two S segments and maintained its transgene. We demonstrated that r3PIC-GFP was expressed during the course of persistent infection in AGR mice. nat But those two S-segments recombining the NP and GP genes onto a single RNA segment, thereby We wanted to determine whether the FP transgene had been eliminated. To test this possibility, We extracted viral RNA from serum samples collected from each animal 147 days after viral infection. We have designed and constructed two NP and GP-binding domains, which bind to the Pichinde virus NP and GP, respectively. rPIC wt PCR on genomic templates is predicted to produce an amplicon of 357 base pairs. Using primers spanning the intergenic region ("IGR") of the Pichinde virus S segment, Such amplicons were indeed rPIC wt or r3PIC-GFP nat Noise When viral RNA from animals infected with either r3PIC-GFP was used, art Feeling When viral RNA from blood of infected mice was used, no results were obtained (Figure 13; each lane is 8–10 represent RT-PCR products from one individual mouse in the experiment shown).

[0336] Taken together, these data suggest that r3PIC-GFP is a novel marker for the pathogenesis of persistent infection in AGR mice. nat The two S segments (S-GP / GFPnat and S-NP / GFP) were recombined to form the NP and GP open reads. This shows that the binding frame of the RNA is recombined into one single segment of RNA. This resulted in loss of GFP transgene expression and re-expansion upon collection from blood and in cell culture. The increased viremia seen in cell cultures and in levels of viremia was evident In mice, the proliferation ability of rPIC wt In contrast, r3PIC-GFP increased the proliferation ability of art teeth , as evidenced by the lack of RT-PCR amplicons spanning the NP and GP genes. The S segment did not recombine.
