  • Patent number: 8716230
    Abstract: 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.
