  • Mutant rex genes encoding transdominant repressors of HIV/HTLV replication
    Patent number: 6339150
    Abstract: Transdominant repressors of viral gene phenotypic expression derived from the rev gene product of HIV-1 or the rex gene product of HTLV-1 and corresponding mutated genes, having the capability of repressing the Rev function in HIV-1 and/or the Rex function in HTLV-I and HTLV-II and, in some cases, both the Rev and the Rex function and are, therefore, active in more than one viral species. Such transdominant viral mutants are useful as anti-viral agents to, for example protect cells against the deleterious effects of viral, e.g. HIV-1, infection.
    Type: Grant
    Filed: August 21, 1998
    Date of Patent: January 15, 2002
    Assignee: Duke University
    Inventors: Helmut Bachmayer, Ernst Boehnlein, Warner C. Greene, Joachim Hauber

  • Influenza sub-unit vaccine
    Patent number: 4140762
    Abstract: This invention provides a novel sub-unit vaccine comprising a mixture of the hemagglutinin and neuraminidase components of the virus in the substantial absence of non-essential viral particles.

    Filed: September 23, 1977
    Date of Patent: February 20, 1979
    Assignee: Sandoz Ltd.
    Inventors: Helmut Bachmayer, Gerhard Schmidt
  • Process for isolating the immunogenic components of influenza viruses
    Patent number: 4064232
    Abstract: The immunogenic components from influenze viruses are isolated by selectively solubilizing the component in an aqueous media with a cationic detergent.
