Patents by Inventor Kazunobu Tachibana

Kazunobu Tachibana 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).

  • Publication number: 20130236889
    Abstract: This invention provides a therapeutic agent for inhibiting neovascularization, a therapeutic agent for a solid cancer, a therapeutic agent for a disease pathologically caused by neovascularization, and a therapeutic agent for repairing a tissue comprising as the effective ingredient, a substance that potentiates the action of CXCR4. Based on the finding that vascularization is suppressed in CXCR4 knockout mice, it becomes possible to prepare a therapeutic agent for suppressing vascularization, a therapeutic agent for a solid cancer, a therapeutic agent for a disease pathologically caused by neovascularization, each of which comprises as the effective ingredient, a substance that inhibits the action of CXCR4, as well as to prepare a therapeutic agent for repairing a tissue comprising as the effective ingredient, a substance that potentiates the action of CXCR4. Methods for treatment are made possible that use these therapeutic agents.

  • Patent number: 7361737
    Abstract: The present invention pertains to a DNA encoding a polypeptide including an entire sequence of the amino acid sequence as shown by SEQ ID NO: 2 or a partial sequence thereof, or a polypeptide including the polypeptide described above, wherein any of the polypeptides has an activity of a receptor capable of binding to a murine PBSF/SDF-1; a polypeptide encoded by the DNA described above, wherein the polypeptide has an activity of a receptor capable of binding to a murine PBSF/SDF-1; cells expressing the polypeptide described above and a human CD4 protein; and a method of screening an AIDS onset inhibitor or an HIV-1 infection inhibitor, characterized by the use of the cells described above. According to the present invention, there can be provided a novel murine CXC chemokine receptor gene, a method of screening an HIV-1 infection inhibitor, and the like, each of which is useful in studies of a therapeutic agent for AIDS and the functional mechanism of HIV-1 infection.
