[Technical Field]
[0001] This application was filed on November 4, 2015, the disclosure of which is incorporated herein by reference in its entirety. The benefit of filed U.S. Provisional Patent Application No. 62 / 250,639 is claimed.
[0002] (Reference to electronically submitted sequence listing) This application is based on a file created on November 2, 2016, entitled "Sequence _Listing_13194-014-228.TXT" along with this application. The submitted sequence listing is incorporated by reference. [Background technology]
[0003] (1. Introduction) Provided herein are vaccines and methods for the prevention and treatment of hepatitis B virus infection. Also provided herein are genetically modified arenavirus vectors suitable for use in the Pharmaceutical compositions and methods for the treatment of hepatitis B virus infection. Provided are pharmaceutical compositions, vaccines, and methods for treating hepatitis B virus infection. Thus, the present application provides an immunotherapy for hepatitis B virus infection.
[0004] (2.Background) 2.1 Pathogens and Diseases Hepatitis B virus (HBV) is a double-stranded enveloped virus of the Hepadnaviridae family. Virus particles are icosahedral nuclei composed of an outer lipid envelope and proteins. The nucleocapsid contains the viral DNA and reverse transcriptase activity. The outer envelope contains the DNA polymerase that is responsible for the delivery of the virus to susceptible cells. HBV contains embedded proteins involved in the binding and entry of HBV. It replicates in monkey liver cells but does not grow in artificial cell cultures.
[0005] The outcome of HBV infection is age-dependent and includes asymptomatic infection, acute hepatitis B, chronic HBV infection, and liver cirrhosis. Acute hepatitis B accounts for approximately 1% of perinatal infections and 1% of childhood infections (ages 1-5 years). Fulminant hepatitis occurs in 10% of cases (children under 5 years of age) and 30% of cases of late infection (people over 5 years of age). It occurs in 0.1-0.6% of cases; the mortality rate from fulminant hepatitis B is approximately 70%. The incidence of HIV infection is inversely related to the age of acquisition, with approximately 80-90% of those infected perinatally and 90% of those infected before age 6. It occurs in approximately 30% of children with HIV infection, and less than 5% of infections occur in otherwise healthy adults (Hyams (1995, Clinical Infections Diseases 20:992-1000). HIV co-infection and alcohol Comorbidities, including ingestion of flu or aflotoxin or both, are associated with hepatitis B. It may play an important role in the development of associated pathologies. It is estimated that 10% of the 10 million people are co-infected with HBV.
[0006] Individuals with chronic HBV infection have a 15-20% increased risk of premature death due to HBV-related cirrhosis and HCC. 5% (Beasley and Hwang, 1991, 1990 National Survey of Viral Hepatitis and Liver Disease) Proceedings of the 1990 International Symposium: Current Issues and Future Prospects nal Symposium on Viral Hepatitis and Liver Disease: Contemporary Issues and Futu re Prospects), 532-535). Acute HBV infection is characterized by the surface antigen HBsAg and the core antigen HB It is characterized by the presence of immunoglobulin M (IgM) antibodies against cAg. During the replication phase, patients produce extracellular and secreted forms of HBcAg, which can be found in the patient's serum. They are also seropositive for HBeAg, a marker of active replication in chronic hepatitis. Antibodies to HBsAg (anti-HBs) are detected after a few weeks, and Chronic infection is characterized by persistence of HBsAg (>6 months). Persistence of HBsAg is associated with chronic liver disease and HBV later in life. The presence of HBeAg is a primary marker of risk for developing HBeAg in the blood and body of infected individuals. This indicates that the fluid is highly contagious.
[0007] (2.2 Epidemiology and Public Health) The disease caused by the hepatitis B virus is distributed worldwide. There are 2 billion people Of these, approximately 360 million people are chronically infected. This puts them at risk of serious illness and death, primarily from cirrhosis of the liver and hepatocellular carcinoma (HCC). Mathematical modelling for the year 2000 has estimated that the number of deaths from HBV-related diseases worldwide is It is estimated that there are approximately 600,000 cases each year (Goldstein et al., 2005, International J. Epidemiology gy 34:1329-1339). Humans are the only reservoir for HBV. The virus spreads through infected blood. Transmission is by percutaneous and mucosal exposure to semen and other body fluids, primarily semen and vaginal fluids. The average duration is 75 days, but can vary from approximately 30 to 180 days. The HBV surface antigen (HBsAg) is expressed during infection. It can be detected in serum 30-60 days after administration and persists for a variable period of time. Hepatitis B epidemics are characterized by the prevalence of HBsAg in the general population of a particular geographic area. This is explained by the rate, which varies considerably across the world: HBsAg prevalence of over 8% The prevalence is typical of high-incidence areas, with a prevalence of 2-7% seen in moderate-incidence areas. However, in low-incidence areas, less than 2% of the population is HBsAg positive.
[0008] In areas with high incidence, HBV is transmitted from mother to child at birth or from person to person during early childhood. spread is most common (Goldstein et al., 2005, International J. Epidemiology y 34:1329-1339; Wong et al., 1984, Lancet 1:921-926; de la Hoz et al., 2008 In International J. Infectious Diseases 12:183-189). Perinatal or early childhood transmission is the most frequent. may account for over one-third of chronic infections in low-risk areas (Margolis et al., 1999 5, JAMA 274:1201-1208), these settings are prone to sexually transmitted infections and, particularly, to the risk of infection among injecting drug users. The primary route of infection is through the use of contaminated needles between patients (Goldstein et al., 2002, J.I. nfectious Diseases 185:713-719).
[0009] (2.3 Current Treatment) Widespread hepatitis B vaccination significantly reduces rates of HBV infection and HCC However, once chronic HBV infection is established, conventional therapy does not usually result in sustained control of viral replication and liver damage in most patients, Treatment remains a challenge.
[0010] Currently approved antiviral treatments for chronic hepatitis B include pegylated (PEG) recombinant interferon. These drugs include steroid alpha and viral DNA polymerase inhibitors. This may reduce liver cirrhosis progression, reduce the incidence of HCC, and improve long-term survival. However, treatment is complicated by drug toxicity and is difficult for chronically infected individuals. The virus level in the blood is low even after standard treatment. In individuals with HIV infection, the viral DNA in the liver is reduced to an almost undetectable level, but the decrease in the viral DNA in the liver is only slight. As a result, relapse of viremia often occurs after treatment interruption, leading to chronic HBV Those infected must continue lifelong treatment. Even after 10 years of treatment, the drugs only reduced liver failure by 40-70% and cirrhosis and mortality from liver cancer remains high.
[0011] (2.4 Hepatitis B and the Immune System) Chronic hepatitis B infection is characterized by dysfunction of innate and adaptive antiviral immunity (Bertoletti and Ferrari, 2012, Gut 61:1754-1764). In contrast, in patients with resolved HBV infection, HBV-specific immunity in the human body is strong and multifunctional. Several mechanisms contribute to the production of high levels of viral resistance. Dysfunction of HBV-specific T-cell immunity and hepatic tolerance in patients with chronic hepatitis B, including primary hematopoietic disease This may contribute to the immune microenvironment (Jenne and Kubes, 2013, Nat. Immunol. 14:996-1006). Previous studies have shown that suppression of viral replication induces a transient and partial increase in antiviral T cell immunity. It has been shown that the immune system can recover from high levels of antigenemia, which may contribute to long-term survival. This supports the hypothesis that early exposure can cause antiviral T cell dysfunction (Boni et al. References, 2003, J. Hepatol. 39:595-605).
[0012] It can reverse the impaired immune state of chronic hepatitis B and restore antiviral immunity. A therapeutic vaccine would theoretically eliminate viremia and reduce intrahepatic HBV DNA levels to zero. and therefore may hold considerable promise for the treatment of HBV.
[0013] Recently, HBV vaccines have been developed for the treatment and control of HBV infection in HBV carriers and persistently infected patients. has been identified as a promising treatment strategy for rheumatoid arthritis (Michel and Tiollais, 2010, Pathol. Biol. (Paris) 58:288-295; Liu et al., 2014, Virol. Sin. 29:10-16). chronic active HB In approximately 50% of patients with HBV, specific therapy with conventional anti-HBV vaccination effectively inhibits HBV replication. effectively reduced the immune tolerance to HBsAg protein (Couillin et al., 1999). , J. Infect. Dis. 180:15-26). However, to date, no HBsAg-based vaccines have been used. Monotherapy with HBV did not result in durable control of HBV replication and / or liver damage (Akbar et al., 2014). 13, Hepatobiliary Pancreat. Dis. Int. 12:363-369), new therapeutic strategies are powerful and long-lasting. There is a need to provide a sustained antiviral immune response and long-term control of HBV replication.
[0014] The failure of past therapeutic vaccine approaches has undermined current knowledge about immune responses in chronic HBV infection. highlighting the challenges and limitations of this knowledge (Michel et al., 2011, J. Hepatol. 54:1286-1296). The combination of a high viral load state, such as chronic hepatitis B, and a permissive liver microenvironment may contribute to the development of antiviral T cells. This may make it difficult to achieve complete restoration of immune immunity.
[0015] Intensive research is currently underway to better understand the immune response in hepatocytes, how HBV circumvents innate immunity, and The focus is on the mechanisms of immune defence and the appropriate selection of patients likely to benefit from immunotherapy. This may increase the efficacy of therapeutic vaccination (Michel et al., 2015, Med. Mich. Crobiol. Immunol. 204:121-129). Summary of the Invention

The progeny modified arenaviruses can be generated as described in Section 6.3.
[0105] The wild-type arenavirus genome consists of a short (~3.4 kb) RNA segment and a large (~7.2 kb) RNA segment. The short segment is composed of the nucleoprotein NP gene and the glycoprotein GP gene. The large segment contains the ORF encoding the RNA-dependent RNA polymerase L gene. and matrix protein Z gene.
[0106] (a) Replication-deficient arenavirus vector In certain embodiments, the arenavirus vector is a replication-deficient, bipartite arenavirus vector. In certain embodiments, the arenavirus vector is replication-deficient. It is a tripartite arenavirus vector that encodes a glycoprotein gene to target the immune response to the protein. By substituting one or more HBV antigens that induce a response, wild-type ArenA virus Viruses can be made replication-deficient to generate vaccine vectors.

[0108] Arenavirus disease and immunosuppression in wild-type arenavirus infections are unchecked. It is known that they arise from viral replication without any specific mechanism for the release of particles from their genome, e.g. By deleting the Z gene, which is required for the infection of target cells, or the GP gene, which is required for the infection of target cells, Thus, replication of the arenavirus vector, i.e., production of infectious progeny virus particles, By disabling the ability to vaccinate, the total number of infected cells can be reduced, for example, by administering the vaccine to the recipient. inocula used in or inadvertently used on people or animals involved in medical or biotechnological applications. Therefore, the inoculum to be propagated can be limited. Disabling replication of vector particles is a consequence of intentional or unintentional propagation of vector particles. Provided herein is an important embodiment of a method for preventing HBV disease by administering to a subject a HBV-positive cell line expressing an HBV antigen. The object of this invention is to take advantage of the need for copy invalidation in a beneficial way. In embodiments, arenavirus particles are made replication-deficient by genetic modification of their genome. Such modifications to the Nomu include: deletion of an ORF (e.g., an ORF encoding a GP, NP, L, or Z protein); Functional inactivation of an ORF (e.g., an ORF encoding a GP, NP, L, or Z protein). For example, This can be achieved by introducing missense or nonsense mutations. ; Altering the sequence of the ORF (e.g., replacing the S1P cleavage site with the cleavage site of another protease); Mutagenesis of either the 5' or 3' end of one of the genome segments; Mutagenesis of intergenic regions (i.e., intergenic regions of L or S genome segments) Examples include:
[0109] In certain embodiments, an infectious arenavirus expressing an HBV antigen described herein The virus is lymphocytic choriomeningitis virus (LCMV), wherein the S segment of the virus was modified by replacing the ORF encoding the GP protein with the ORF encoding the HBV antigen. It has been done.
[0110] In one embodiment, the wild-type arenavirus vector genome (FIG. 1) contains both segments. At least the necessary 5' and 3' untranslated regions (UTRs) and / or intergenic regions (IGRs) of the Without wishing to be bound by theory, the gene can be designed to retain the necessary regulatory elements. However, minimal trans-acting factors for gene expression in infected cells are expressed. These remain in the vector genome as ORFs that can be used to and can be under the control of a promoter other than the native one, or can be expressed from an internal ribosome entry site. The nucleic acid encoding the antigen is driven by an endogenous arenavirus promoter (i.e., the promoter of the S segment The 5'UTR, 3'UTR, 5'UTR, 3'UTR of the L segment are transcribed from one of the following: In the HBV genome, the nucleic acid encoding the HBV antigen is synthesized by the viral RNA-dependent RNA polymerase. , read by cellular RNA polymerase I, RNA polymerase II, or RNA polymerase III A heterologous promoter sequence can be introduced, for example, a viral UTR. Duplicate viral promoter sequences found naturally in the 28S ribosomal RNA promoter, It is expressed from the β-actin promoter or the 5S ribosomal RNA promoter. In some embodiments, the ribonucleic acid encoding the HBV antigen is used alone or in combination with an arenavirus protein. The protein is transcribed and translated as a read-through by fusion with the protein ORF, and then expressed in the host cell. Expression of the ribosome may involve the insertion of one or more, e.g., two, three, or four, internal ribosome entry sites at appropriate locations. This can be enhanced by introducing it into the viral transcript sequence.

[0171] 6.3 Generation of infectious arenaviruses expressing HBV antigens Typically, arenavirus particles are generated using standard reverse genetic techniques, as described for LCMV. It can be produced recombinantly by conventional techniques (L. Flatz, A. Bergthaler, J.C. de la To rre, and D.D. Pinschewer, Proc Natl Acad Sci USA 103:4663-4668, 2006; A. B. Sanchez and JC de la Torre, Virology 350:370, 2006; E. Ortiz-Riano, B References Y. Cheng, JC de la Torre, and L. Martinez-Sobrido, J Gen Virol. 94:1175-88. , 2013).
[0172] (a) Replication-deficient arenavirus To generate infectious, replication-deficient arenaviruses for use with the present invention, Although techniques such as these can be used, the genome of the rescued virus should be analyzed as described in Section 6.1. These modifications can be: i) Four arenavirus ORFs (glycoprotein (GP); nucleoprotein (NP); matrix protein Z) ; RNA-dependent RNA polymerase L) one or more, for example, two, three, or four It activates or functionally inactivates the virus, preventing the formation of infectious particles in normal cells, but still permitting gene expression in host cells infected with the virus vector; and and ii) the ability to introduce nucleic acids encoding HBV antigens. The replication-deficient viruses are described in International Patent Publication No. 2004 / 0022994, each of which is incorporated herein by reference in its entirety. Patent application publication WO 2009 / 083210 (application number PCT / EP2008 / 010994) and international patent application publication WO 20 and can be produced as described in PCT Application No. PCT / EP2014 / 055144. do.
[0173] Once generated from the cDNA, the infectious, replication-deficient arenaviruses provided herein can be propagated in complementing cells, which are replication-deficient due to modifications of their genomes. A cell that provides functionality that has been removed from the arenavirus (e.g., GP protein) Complementing cells can also express the nucleotide sequence of a gene encoding the nucleotide sequence of a ... , certainly providing GP proteins).
[0174] Have one or more of the viral genes in the arenavirus vector been removed? or functionally inactivated (here, deletion of glycoprotein GP is taken as an example), The viral vector is then transfected with a deleted viral gene, e.g., GP, in this example. Such complementing cell lines (hereafter referred to as C cells) can be generated and propagated in the cells provided. The cells are derived from mammalian cell lines such as BHK-21, HEK 293, VERO, or other cells (referred to herein as BHK -21) contains one or more plasmids (C-plasmids) for the expression of the viral gene of interest. It is produced by transfecting a complementary plasmid called a C-plasmid. The smid contains one or more expression vectors suitable for expression in mammalian cells, accompanied by a polyadenylation signal. The cassette may contain, for example, a mammalian polymerase II promoter, such as a CMV or EF1α promoter. The missing viral genes are expressed in arenavirus vectors generated under the control of a human virion gene promoter. Furthermore, the complementing plasmid contains an expression cassette suitable for gene expression in mammalian cells. a mammalian selection vector under the control of a polymerase II expression cassette, such as those described above. Markers, e.g., characterized by puromycin resistance or by the subsequent transcription of viral genes. In particular, internal ribosome entry sites, such as the internal ribosome entry site of the encephalomyocarditis virus, followed by a mammalian resistance marker. The plasmid further features a bacterial selection marker, such as an ampicillin resistance cassette. do.
[0175] Cells that can be used include, for example, BHK-21, HEK 293, MC57G, or others. They are maintained in culture and this is achieved by commonly used strategies, e.g., calcium phosphate, liposomes, Complementation plus fusion was performed using either a fusion-based protocol or electroporation. After several days, a suitable selection agent, e.g., puromycin, is gradually introduced. Surviving clones are isolated and subcloned according to standard procedures. and then analyzed by Western blotting or flow cytometry with an antibody against the viral protein of interest. High-expressing C-cell clones are identified using a cytometry method. As an alternative to the use of transfected C cells, transient transfection of normal cells can be used to can complement missing viral genes in each of the following steps: Additionally, helper viruses can be used to provide missing functionality in trans. do.
[0176] The plasmids that can be used are of two types: i) in this example, e.g., LCMV Minimal trans-acting factors of arenaviruses derived from NP and L proteins ii) two plasmids called TF-plasmids for intracellular expression of the alleles in C cells; and Transformation of viral vector genome fragments, e.g., segments with engineered modifications, into C cells For intracellular expression, a plasmid called a GS-plasmid can be used. The smids deliver the NP and L proteins of each arenavirus vector to mammalian cells. An expression cassette suitable for protein expression in animal cells, typically e.g., a mammalian polymerase Either of these may be under the control of a gene II promoter, such as a CMV or EF1α promoter. The GS-plasmid expresses either one of the two in combination with a polyadenylation signal. , expressing the small (S) and large (L) genome segments of the vector. Typically, a polymerase I-driven expression cassette or a T7 bacteriophage RNA polymerase (T7- ) driving expression cassette can be used, the latter incorporating a 3'-end ribozyme into the primary transcript. It is used preferentially for processing to generate accurate ends. When using a T7-based system Expression of T7 in C cells requires the use of a further plasmid that provides T7, constructed in a similar manner to the TF-plasmid. This must be achieved by including an expression plasmid containing the Alternatively, the C cells are engineered to further express T7 in a stable manner. In this case, the TF plasmid and the GS plasmid can be the same, i.e., the genomic sequence and trans-acting factors are expressed on one plasmid by T7, polI, and polII promoters. can be transcribed from
[0177] For recovery of the arenavirus vectors, the following procedure can be used: : In a 6-well plate, C cells (usually 80% confluent) were transfected with two TF-plasmids and two GS-plasmids. In one embodiment, a mixture of TF and G plasmids is transfected. The S plasmid can be the same, i.e., the genomic sequence and trans-acting factors are It can be transcribed from one plasmid by the T7, polI, and polII promoters. For this reason, commonly used strategies, such as calcium phosphate and liposome-based Either a direct transfer protocol or electroporation can be utilized.
[0178] After 3-5 days: Collect the culture supernatant (arenavirus vector preparation), dispense it, and incubate it in an aliquot. Store at 4°C, -20°C, or -80°C depending on how long the viral vector will be stored. The infectious titer of the arenavirus vector preparation was then determined by immunofocal assay on C cells. The results are evaluated by a ELISA.
[0179] The present invention further provides a cell culture infected with an infectious arenavirus that expresses an HBV antigen. When used to express HBV antigen in cultured cells, Two procedures can be used: i) injecting a cell type of interest with one or more of the arenavirus vector preparations described herein; For example, by infecting at a multiplicity of infection (MOI) of 2, 3, or 4, all cells were infected with HBV immediately after infection. Resulting in the production of V antigen. ii) Alternatively, a lower MOI can be used, allowing individual cell clones to express their viral load. The arenavirus vector can then be used to select for a dynamic HBV antigen expression level. Due to the non-cytolytic nature of the cloning medium, individual clones can be propagated indefinitely. Regardless of the method, HBV antigens are then extracted from the culture supernatant or the culture medium depending on the characteristics of the HBV antigens produced. However, the present invention provides a method for the preparation of a protein comprising: These two strategies are not limited to the above, and infectious replication-deficient arenavirus vectors may also be used. Other methods of using HBV antigens to drive expression can be considered.
[0180] Alternatively, a rescue system consisting of three plasmids can be used: (1) the first plasmid The smid is transfected by transcription with polymerase II and subsequent translation. (2) the second plasmid expresses the protein NP by transcription with polymerase I; This not only generates the (minus-strand) L-segment of the LCMV genome, but also The L protein is produced by transcription from the same template by polymerase II in the opposite direction to the promoter. (3) The third plasmid expresses the S sequence of the LCMV genome by transcription with polymerase I. -segment (encoding antigen coding sequences in place of LCMV glycoproteins). μg of each plasmid was used for electroporation of C-cells, and the cells were then cultured for 6 weeks. The cells are seeded onto well plates and incubated at 37°C. After incubation, the cells are transferred to the well plates. The cells and supernatant from the transfection were mixed with freshly plated C-cells and incubated at defined time points post-infection. Once the vector is produced, it is harvested and cleared from cells and debris. , antigens of oncogenic viruses and / or immunomodulatory peptides, polypeptides, or proteins The nucleic acid encoding the protein (see Section 6.2) can be inserted into a plasmid, from which The genome segment of the infectious replication-defective vector is transcribed by any technique known to those skilled in the art. will be done.
[0181] Have one or more of the viral genes in the arenavirus vector been removed? or functionally inactivated (here, deletion of glycoprotein GP is taken as an example), The viral vector can be engineered to contain a deleted or functionally inactivated viral gene (e.g., GP). The resulting virus can be produced and propagated in cells that provide the virus in trans. The body is infectious but contains deleted or functionally inactivated viral genes (e.g., GP). Complementation is a process whereby the host cells lack the necessary complementation to produce additional infectious progeny particles. Cells may be stably transfected, transiently transfected, or transfected with The missing functionality can be provided by infection with a helper virus that expresses the missing functionality. This can be done.

[0407] (6.9 Assay) Assay for measuring the infectivity of arenavirus vectors Any assay known to one of skill in the art can be used to measure the infectivity of an arenavirus vector preparation. For example, determining the virus / vector titer can be used to This can be done by a Fully Functional Unit Assay (FFU assay). For example, HEK 293 cells expressing LCMV GP protein are plated and the virus / vector is then transfected. After an incubation period, cells form a monolayer. The plate is then covered with methylcellulose to allow the virus to attach to the cells. Upon further incubation, the originally infected cells release viral progeny. Because the cells are layered, the spread of new viruses is restricted to neighboring cells. Each infectious particle gives rise to a circular zone of infected cells called a focus. Such foci can be visualized using antibodies against LCMV-NP and an HRP-based color reaction. This allows for counting of the virus / vector titer. can be calculated in focus-forming units per milliliter (FFU / mL).

To detect specific peptides, T cells are incubated with the peptide (usually fluorescently labeled). The antigen-specific T cells must recognize both the tetramer of MHC molecules that are specifically designed for them. The tetramers are then detected by flow cytometry via the fluorescent label.
[0417] ELISPOT assay for detection of antigen-specific CD4+ T cell proliferation Any assay known to those skilled in the art can be used to test antigen-specific CD4+ T cell responses. For example, an ELISPOT assay can be used (see, for example, Czerkinsky CC et al. J Immunol Methods. 1983; 65:109-121; and Hutchings PR et al., J Immuno (See Methods. 1989; 120:1-8). Briefly, the assay involves the following steps: Coat the immunospot plate with anti-cytokine antibodies. The cells secrete cytokines, which are then washed away. The plate is then coated with a second biotinylated anti-cytokine antibody. Visualize with the Gin-HRP system.
[0418] Intracellular cytokine assay for detecting the functionality of CD8+ and CD4+ T cell responses Test the functionality of CD8+ and CD4+ T cell responses using any assay known to one of skill in the art. For example, intracellular cytokine assays combined with flow cytometry can be used. (See, for example, Suni MA et al., J Immunol Methods. 1998; 212 :89-98; Nomura LE et al., Cytometry. 2000; 40:60-68; and Ghanekar SA et al. (See Clinical and Diagnostic Laboratory Immunology. 2001; 8:628-63). In summary, this assay involves the following steps: infecting cells with specific peptides or proteins; activation of cytokines, and inhibitors of protein transport (e.g., brefeldin A) After washing, antibodies against other cell markers can be added to the cells. The cells are then fixed and permeabilized. Anti-cytokine antibodies are added, and the cells are then flow- It can be analyzed by cytometry.
[0419] Assay to confirm replication deficiency of viral vectors Any assay known to those skilled in the art that determines the concentration of infectious and replicative viral particles can be used to measure replication-deficient viral particles in a sample. For example, non-complementing cells An FFU assay using (as described in
[0408] ) can be used for this purpose. .
[0420] Additionally, plaque-based assays provide information on plaque-forming units (PFU) in virus samples. This is the standard method used to determine virus concentration. Confluent monolayers of host cells are infected with various dilutions of virus and plated onto a semi-solid medium such as agar. Cover with medium to prevent the virus from spreading uncontrollably. When the virus successfully replicates itself in cells within the cell monolayer, viral plaques are formed. (See, for example, Kaufmann, SH; Kabelitz, D. (2002). Methods in Microbiology Immunology of Infection. Academic Press. ISBN Plaque formation occurs over a period of 3 to 14 days, depending on the virus being analyzed. Plaques can be roughly counted manually and the results used to prepare plates. This was used in conjunction with the dilution factor used to determine the number of plaque formation units per unit volume of sample. Calculate the number of PFU / mL. The PFU / mL result represents the number of infectious, replicative particles in the sample.
[0421] (Measurement of viral load in blood or liver) The volume in the blood or liver can be determined using any assay known to those skilled in the art to determine viral load. The number of HBV particles per 1000 μg / ml can be detected (see, e.g., Mendy et al., 2010, J. Viral Hepat. 17(2): 115-122). Non-limiting examples of such assays include nucleic acid-based These include nucleic acid-based tests, such as PCR, and non-nucleic acid-based tests.
[0422] (liver biopsy) For example, those skilled in the art would be able to perform liver biopsies to screen patients for chronic HBV infection or liver cancer. Any known procedure can be used to determine the extent of liver damage. Typical examples include percutaneous needle biopsy, laparoscopic biopsy, and intravenous biopsy. In an embodiment, a liver biopsy is used to identify ground-glass liver cells when the cells are examined under a light microscope. The observation of ground-glass hepatocytes indicates the presence of HBsAg in the liver cells. It is something that is.
[0423] Assay for viral antigen expression Any assay known to one of skill in the art may be used to measure viral antigen expression. For example, an FFU assay (as described in
[0408] ) can be performed. For detection, monoclonal or polyclonal antibodies against each viral antigen are used. Use a whole body preparation (transgene-specific FFU).
[0424] Additionally, Western blotting (as described in
[0415] ) can be performed. can.
[0425] (microparticle enzyme immunoassay) AXSYM® HbsAg (Abbott) is a sera or antibody prepared from adult, pediatric, and neonatal samples, including those from pregnant women. This is a microparticle enzyme immunoassay (MEIA) for the detection of HBsAg in plasma. It can be used as a diagnostic aid for acute or chronic HBV. It can also be used to check the presence of
[0426] To perform the assay, a sample of the patient's blood is subjected to a test for detection antibodies and a test for HBV (e.g., The blood sample is placed in a reaction well containing microparticles coated with antibodies (anti-HBV antigen). If HBV proteins (e.g., HBsAg) are included, they will bind to the microparticles in the reaction wells. This reaction is detected by another substance that emits light, and then this light is measured to If the initial test is positive, the patient's blood is then The fluid is retested to confirm the presence of HBV (e.g., HBV antigen). Enzyme immunoassays can be used to measure the presence of HBsAg or other HBV antigens.
[0427] (Other HBV assays) A sample of the patient's blood is contacted with either HBV antibodies or HBV antigens. Antibodies against HBsAg and HBeAg, antibodies against HBsAg, IgM antibodies against HBeAg and HBcAg These include antibodies against the HBV antibody, and HBcAg. If a patient is infected with HBV, The antigens and / or antibodies that react with the test will cause a chemical reaction when the test is being performed. This assay identifies which HBV antigens and / or antibodies are present in the patient's blood. This allows for the detection of the stage of HBV.

[0433] 7. Working Example 7.1 Arenavirus Vector Genome Design / Vector Construction Established techniques (U.S. Patent Application Publication No. US 2010 / 0297172 A1; and Flatz L. et al., Nat Med. 2010 March; 16(3): 339-345), each HBV antigen or its specific Designing LCMV- and Junin virus (JUNV)-based vaccine vectors expressing the domains (Figure 1).
[0434] (7.2 Vaccine against Hepatitis B Virus) Candidate vaccines against hepatitis B virus (HBV) include rLCMV systems expressing pre-S2 / S and rJUN. Junin virus strain Candid#1 vectors (rLCMV / pre-S2 / S, rJUNV / pre-S2 / S), expressing HBc The vectors (rLCMV / HBc, rJUNV / HBc) that produce HBs and HBc ORF-containing fusion proteins The vector expressing HBsHBc (rLCMV / HBs), and the vector expressing HBe (rLCMV / HBe, rJUNV / HBe). The vector contains a replication-deficient construct (rLCMV, also known as r2LCMV, rJUNV, and Also called r2JUNV) and replication-competent tripartite constructs (r3LCMV, r3JUNV; e.g., Emon et al., 2009, PNAS, 106(9):3473-3478), where the transgene is So-called "artificial" arrangement (r3LCMV art , r3JUNV art ). Mouse (e.g., C 57BL / 6 mice) in a homologous or heterologous primary-boost vaccination The animals are immunized with one or a combination of the constructs. Administration can be intraperitoneal, intramuscular, or intravenous. It is administered by intravenous route. The dose is 10 4 ~10 7 Within the scope of the focus forming unit (FFU) HBV-specific CD8+ T cells were measured in the blood and / or spleen at time points ranging from 7 to 100 days after immunization. For example, to determine the magnitude of CD8+ T cell responses to HBV-derived epitopes, Measure T cells using HC class I tetramers in combination with anti-CD8 antibodies can be done.
[0435] In a complementary approach, synthetic peptides are used in intracellular cytokine assays to Directly and selectively stimulates ex vivo blood and / or spleen-derived CD8+ T cells. The cytokine assays include interferon (IFN)-γ, tumor necrosis factor (TNF)-α, and / or It measures the frequency of interleukin (IL)-2-producing CD8+ T cells. Surface expression of CD107a serves as a marker of cytolytic degranulation in flow cytometry (FACS). HBs-derived epitope [ka] , HBs-derived epitopes [ka] , and HBc-derived epitopes [ka] The peptide specificity is analyzed, including:
[0436] 7.3 Immunogenicity of replication-deficient arenavirus-based vectors expressing HBV antigens C57BL / 6 mice (5 mice per group) were administered 10 5 FFU of rLCMV / HBs-HBc (Group 1), rLCMV / HBc (Group 3), rLCMV / pre-S2 (Group 4), or 10 4 FFU of rLCMV / HBs-HBc (second Control mice were left untreated. Ten days after immunization, MHC class II antibodies were detected. CD8+ T cells were measured in blood using HBs-derived epitopes. [ka] H-2K complexed with b Dextramers and HBc-derived epitopes [ka] H-2K complexed with b Dextramer in combination with anti-CD8α antibody was used to treat hepatitis B. Virus-specific CD8+ T cells were identified. The enumerated cells were compared with the total CD8 + B220 - T cells Expressed as a percentage of the pool.
[0437] The results shown in Figure 3 show that the vaccines with rLCMV / HBs-HBc, rLCMV / HBc, and rLCMV / pre-S2 Vaccination resulted in substantial antigen-specific CD8+ responses to the antigens expressed by each vector. These results suggest that vaccination with rLCMV / HBs-HBc induces T cell responses. The induced anti-HBs and anti-HBc CD8+ T cell responses showed a clear dose-dependence. The higher frequency of anti-HBc CD8+ T cells with rLCMV / HBs-HBc immunization compared with HBs-HBc immunization was associated with a higher incidence of HBs-HBc CD8+ T cells. These results indicate that fusion of the two results in enhanced immunogenicity of HBc.
[0438] The frequency of anti-HBs CD8+ T cells was higher after immunization with rLCMV / pre-S2 than after immunization with rLCMV / HBs-HBc. The level was slightly higher after the first 24 h, suggesting that the anti-HBc CD8+ T cell response may have competed with the anti-HBs response for antigen utilization. It's happening.
[0439] 7.4 Immunogenicity of Attenuated Replication-Competent Arenavirus-Based Vectors Expressing HBV Antigens C57BL / 6 mice (5 mice per group) were administered 10 5 FFU r3LCMV / HBs-HB c (group 1), r3LCMV / HBc (group 2), r3LCMV / pre-S2 (group 3), or 10 5 FFU of rLCMV / HBs-HBc( Control mice were left unvaccinated. Eight days after the first injection, HBs and HBc epitope-specific CD8+ T cells were identified using MHC class I multimers. HBs-derived epitopes were measured in blood. [ka] H-2K complexed with b Dextramers and HBc-derived epitopes [ka] H-2K complexed with b Dextramer in combination with anti-CD8α antibody was used to treat hepatitis B. Virus-specific CD8+ T cells were identified. The enumerated cells were compared with the total CD8 + B220 - T cells as a percentage of the pool (Figure 4A) or as a percentage of circulating lymphocytes in the blood ( Figure 4B).
[0440] The results shown in Figure 4 demonstrate that all r3LCMV-based constructs and the replication-deficient rLCMV / H Bs-HBc reference vectors are immunogenic and, respectively, specific for their vectored antigens. Furthermore, the results show that epitope-specific CD8+ T cells were generated. When target CD8+ T cells were enumerated as a percentage of circulating lymphocytes, replicating r3LCMV / HBs -HBc is shown to be more immunogenic than its replication-deficient counterpart, rLCMV / HBs-HBc.
