  • Interferon tau compositions and methods of use
    Publication number: 20040146989
    Abstract: The present invention describes the production of interferon-&tgr; proteins and polypeptides derived therefrom. The antiviral and anticellular proliferation properties of these proteins and polypeptides are disclosed. One advantage of the proteins of the present invention is that they do not have cytotoxic side-effects when used to treat cells. Structure/function relationships for the interferon-&tgr; protein are also described. In one aspect, the invention includes ovine interferon-&tgr;. In another aspect the invention includes multiple forms of human interferon-&tgr;.
    Type: Application

  • Hybrid interferon &tgr;/type I interferon polypeptides
    Patent number: 6174996
    Abstract: The invention provides fusion proteins comprising an N-terminal region derived from an interferon-tau (IFN-&tgr;) polypeptide and a C-terminal region derived from another type I interferon polypeptide, such as IFN-&agr; or IFN-&bgr;. The fusion proteins exhibit reduced cytotoxicity as compared to the corresponding unmodified type I interferons.

  • Antitumor therapy using ovine or bovine interferon-tau
    Patent number: 5958402
    Abstract: The invention provides antitumor therapeutic methods employing bovine or ovine interferon-tau (IFN-.tau.) proteins and polypeptides. The IFN-.tau. proteins exhibit the antiviral and antiproliferative properties characteristic of type I interferons. An advantage of the invention is that IFN-.tau. has essentially no cytotoxic effects on treated cells as does, for example, IFN-.alpha..
    Type: Grant
    Filed: May 31, 1995
    Date of Patent: September 28, 1999
    Assignee: University of Florida
    Inventors: Fuller Warren Bazer, Howard Marcellus Johnson, Carol Hanlon Pontzer, Troy Lee Ott, Gino Van Heeke

  • Hybrid interferon tau/alpha polypeptides, their recombinant production, and methods using them
    Patent number: 5939286
    Abstract: The present invention describes hybrid interferon fusion polypeptides formed of a first segment that contains the N-terminal amino acid sequence of an interferon-tau polypeptide, and a second segment that contains the C-terminal amino acid sequence of a non-tau interferon type I polypeptide. The two segments are joined in the region of a mature interferon polypeptide between about residues 8 and 37. Also described are nucleic acid sequences encoding such interferon fusion polypeptides, expression vectors containing such sequences, and therapeutic applications of the interferon fusion polypeptides. The therapeutic applications include antiviral and anticellular proliferation applications. One advantage of the interferon fusion polypeptides of the present invention is that they do not have cytotoxic side-effects when used to treat cells.
