Patents by Inventor Shuichi Mitsunaga

Shuichi Mitsunaga 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: 20220175919
    Abstract: We achieved the present invention on the basis of the finding that an excellent therapeutic effect against pancreatic cancer can be obtained by administering an IL-6 inhibitor and an antimetabolite to pancreatic cancer patients. We also found that metastatic lesions from human pancreatic cancer can be reduced and ascites can be eliminated.
    Type: Application

  • Patent number: 10717781
    Abstract: The present inventors discovered that neural invasion is suppressed by inhibiting IL-6 in a model for neural invasion of pancreatic cancer, and completed the present invention. The present inventors also demonstrated that: an IL-6 receptor is expressed in cells of human pancreatic cancer cell lines; and IL-6 enhances the chemotactic and migratory activities and intracellular signaling of pancreatic cancer cells; and thus pancreatic cancer can be treated by inhibiting IL-6. Furthermore, the present inventors found that neural invasion of human pancreatic cancer can be suppressed, from the results of administering IL-6 inhibitors to neural invasion model mice.
