摘要:
Chimpanzee monoclonal antibodies and antigen binding fragments including a γ1-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.
摘要:
The present invention relates to the isolation and characterization of a novel neutralizing chimpanzee monoclonal antibody to hepatitis B virus. The invention provides such antibodies, fragments of such antibodies retaining hepatitis B virus-binding ability, fully human or humanized antibodies retaining hepatitis B virus-binding ability, and pharmaceutical compositions including such antibodies. The invention further provides for isolated nucleic acids encoding the antibodies of the invention and host cells transformed therewith. Additionally, the invention provides for prophylactic, therapeutic, and diagnostic methods employing the antibodies and nucleic acids of the invention.

摘要:
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.
摘要:
A strain of hepatitis E virus from Pakistan (SAR-55) implicated in an epidemic of enterically transmitted non-A, non-B hepatitis, now called hepatitis E, is disclosed. The invention relates to the expression of the whole structural region of SAR-55, designated open reading frame 2 (ORF-2), in a eukaryotic expression system. The expressed protein is capable of forming HEV virus-like particles which can serve as an antigen in diagnostic immunoassays and as an immunogen or vaccine to protect against infection by hepatitis E.

摘要:
The invention relates to the discovery of an HEV strain from a chronically infected patient. The virus grow unusually well in numerous cell cultures. Thus, the invention provides cell cultures, vectors, and vaccine compositions based on the virus. The invention relates, in part, on the identification of a new strain of HEV genotype 3 virus. Strain Kernow-C1 (genotype 3) of HEV, which was isolated from a chronically infected patient, was used to identify human, pig and deer cell lines permissive for infection. Adaptation of the Kernow-C 1 strain to growth in human hepatoma cells selected for a rare virus recombinant that contained an insertion of 174 ribonucleotides (58 amino acids) of a human ribosomal protein gene and additional mutations.
