  • Method of inducing a T lymphocyte response using T-cell immunogens derived from anti-viral proteins
    Patent number: 9572873
    Abstract: Isolated polypeptides related to endogenous anti-viral polypeptides; and compositions, including immunogenic compositions, comprising a subject isolated polypeptide are disclosed herein. A subject isolated polypeptide comprises an amino acid sequence having substantial amino acid sequence identity to a contiguous stretch of amino acids of one or more endogenous anti-viral polypeptides, wherein the endogenous anti-viral polypeptides are polypeptides subject to proteolytic degradation as a result of the activity of one or more viral proteins. Also provided are diagnostic and treatment methods using the subject isolated polypeptides and compositions.
    Type: Grant
    Filed: July 7, 2015
    Date of Patent: February 21, 2017
    Assignee: The Regents of the University of California
    Inventors: Douglas F. Nixon, Stephane Champiat, Keith Garrison
