| Outline of Final Research Achievements |
Transgenic mice in which interleukin 36 gamma is over-expressed specifically in epidermis were generated. A mouse line, Il1f9tg, was established from those mice. When imiquimod was applied on the skin of Il1f9tg F1 mice, the cutaneous inflammation scores of those mice were exacerbated by about 20% in comparison with wild-type mice. In SPF condition, Il1f9tg mice developed no spontaneous eruption. Even in Il1f9tg mice crossed with Il33tg mice, which overexpresses IL-33 in the epidermis, showed no psoriasis-like inflammation of the skin. In addition, 11 patients with pustular psoriasis were subjected to analysis of IL36RN mutations. Of those, a known mutation in IL36RN was found in 2 cases including an oldest case ever reported.
