Abstract: The present invention relates to molecular approaches to the production of nucleic acid sequences, which comprises the genome of infectious hepatitis C virus. In particular, the invention provides nucleic acid sequences which comprise the genomes of infectious hepatitis C viruses of either genotype 3a (strain S52) or genotype 4a (strain ED43). The invention therefore relates to the use of the nucleic acid sequences and polypeptides encoded by all or part of the sequences in the development of vaccines and diagnostic assays for HCV and in the development of screening assays for the identification of antiviral agents for HCV. The invention therefore also relates to the use of viral particles derived from laboratory animals infected with S52 and ED43 viruses.

Abstract: The invention relates to anti-HCV antibodies and more specifically to neutralizing anti-HCV antibodies and their variable and complementarity determining regions (CDR). In particular, the neutralizing anti-HCV antibodies are neutralizing anti-HCV envelope protein 1 (HCV E1) antibodies. Also subject of the invention are compositions comprising these antibodies, CDRs or variable regions, and compounds comprising at least one of the CDRs or variable regions of said antibodies. Further subject of the invention are the application of any of said antibodies, CDRs, variable regions or compounds in HCV prophylaxis, therapy, and diagnosis, as well as methods for producing the antibodies.

Abstract: The present invention discloses nucleic acid sequences which encode infectious hepatitis C viruses and the use of these sequences, and polypeptides encoded by all or part of these sequences, in the development of vaccines and diagnostics for HCV and in the development of screening assays for the identification of antiviral agents for HCV.

Abstract: Chimpanzee monoclonal antibodies and antigen binding fragments including a ?1-chain CDR3 region that bind hepatitis A virus (HAV) antigen are disclosed herein. The antibodies neutralize HAV. Also disclosed are methods for using these antibodies and antigen binding fragments in the detection of hepatitis A virus, the inhibition of infection of a subject with hepatitis A virus, and in screening for agents that affect HAV.

Abstract: The present invention discloses nucleic acid sequence which encodes infectious hepatitis C virus of strain HC-J6CH, genotype 2a, and the use of the sequence, and polypeptides encoded by all or part of the sequence, in the development of vaccines and diagnostics for HCV and in the development of screening assays for the identification of antiviral agents for HCV.
