  • Patent number: 9701982
    Abstract: The present invention relates generally to viral variants exhibiting reduced sensitivity to particular agents and/or reduced interactivity with immunological reagents. More particularly, the present invention is directed to hepatitis B virus (HBV) variants exhibiting complete or partial resistance to nucleoside or nucleotide analogs and/or reduced interactivity with antibodies to viral surface components including reduced sensitivity to these antibodies. The present invention further contemplates assays for detecting such viral variants, which assays are useful in monitoring anti-viral therapeutic regimens and in developing new or modified vaccines directed against viral agents and in particular HBV variants. The present invention also contemplates the use of the viral variants to screen for and/or develop or design agents capable of inhibiting infection, replication and/or release of the virus.

  • Publication number: 20100003262
    Abstract: The present invention provides regulation of expression of toll-like receptors by the hepatitis B (HBV) pre-core protein, or its extracellular expression product the hepatitis B E antigen (HbeAg). Compounds regulating such expression have use in the treatment and prophylaxis of HBV infection in animal. The invention also provides methods for diagnosing HBV and agents useful in diagnostic protocols. The present invention further contemplates methods for monitoring disease states in humans and other animal species, including animal models, and providing an indication of the subject for infection by HBV, or development of other diseased states.
