Outline of Final Research Achievements

In this study, I showed, by using gene-modified mice, that CEACAM20, Src family kinases, and Csk, which are signaling molecules related to the intestinal epithelial-specific protein tyrosine phosphatase SAP-1, were involved in the pathogenesis of colitis, and I revealed some of the molecular mechanisms for the regulation of immune responses in the intestine by these molecules in intestinal epithelial cells.

Academic Significance and Societal Importance of the Research Achievements

腸管における免疫応答の異常は大腸炎や大腸がんの病態形成に深く関わることが知られている。しかしながら、腸管を構成する腸上皮細胞による免疫制御機構については不明な点が多い。本研究により、腸上皮細胞による腸管免疫制御機構の一端が明らかとなった。また、その制御機構の異常が腸炎の病態形成に関わることが腸炎モデル動物を用いた解析から示唆された。今後、更に本研究を進めることにより、免疫異常と関連する腸炎や大腸がんなどの消化管疾患の新たな診断法や治療法の開発の糸口が得られることが期待される。
