Patents by Inventor Hans-Guenther Grigoleit

Hans-Guenther Grigoleit has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9359421
    Abstract: The invention relates to suppressors of endogenous human interferon-gamma (INF-?) applicable in treatment of diseases associated with impaired activity of endogenous IFN-?. The suppressors of the invention are useful in treating autoimmune diseases and for prevention of graft arteriosclerosis and rejection of organs in allograft transplanted patients. The invention includes inactive analogues or variants of IFN-? having preserved affinity to the IFN-? receptor, genetically modified in the domain responsible for triggering the signal transduction pathway.
    Type: Grant
    Filed: April 2, 2014
    Date of Patent: June 7, 2016
    Assignee: TIGO GmbH
    Inventors: Ivan Ivanov, Genoveva Nacheva, Stefan Petrov, Hans-Guenther Grigoleit

  • Patent number: 7973133
    Abstract: The invention relates to an inhibitor of endogenous human interferon-gamma (hIFN-ϝ) in autoimmune diseases, especially in multiple sclerosis. More precisely, the invention relates to inactivated protein derivatives of the hIFN-ϝ with preserved affinity to the hIFN-ϝ receptor. The derivatives represent genetically modified variants of hIFN-ϝ where the C-terminal part of the molecule is either deleted or replaced with a polypeptide sequence of another human protein and a recombinant hIFN-ϝ inactivated by physical or chemical methods.

  • Publication number: 20110135602
    Abstract: The invention relates to suppressor of the endogenous human interferon-gamma (hlFN-?) applicable in treatment of diseases associated with impaired activity of endogenous hlFN-?, especially autoimmune diseases and for prevention of graft arteriosclerosis and rejection of organs in allograft transplanted patients. It is based on inactive analogues of the hlFN-? with pre-served affinity to the hlFN-? receptor, genetically modified in the domain responsible for triggering the signal transduction pathway.
