Patent number: 8716230Abstract: The inventors examined the role of MK in experimental autoimmune encephalomyelitis, which is a human model for multiple sclerosis. As a result, they discovered that MK has the effect of inhibiting regulatory T cells, and that the autoimmune mechanism induced by type 1 helper T cells can be suppressed by inhibiting MK expression or its activity, thereby increasing the number of regulatory T cells. Furthermore, it was found that diseases associated with the functional disorder of regulatory T cells can be treated with the administration of an inhibitor that inhibits MK expression or activity.Type: GrantFiled: October 12, 2010Date of Patent: May 6, 2014Assignee: Ribomic Inc.Inventors: Akio Suzumura, Jinyan Wang, Takashi Matsui, Sadatoshi Sakuma, Shin Miyakawa, Masatoshi Fujiwara, Yoshikazu Nakamura
