Research Abstract

本研究は、Tリンパ球レパトア形成を担う胸腺微小環境の分子本態解明を目的とし、レパトア形成の再構築に基づく免疫疾患の根本的治療法の開発に近づくことを目指している。平成22年度の成果としては、まず、胸腺髄質上皮細胞は胸腺髄質上皮細胞に固有の核内因子Aire依存性にケモカインXCL1を産生し、XCLIによる胸腺内樹状細胞の髄質中央部への誘引が、胸腺における制御性T細胞め産生に重要であり自己寛容の確立に必要であることを明らかにした。また、胸腺皮質上皮細胞と胸腺髄質上皮細胞の分岐機構を明らかにすべく、皮質上皮細胞特異的に発現される胸腺プロテアソーム構成鎖β5tの遺伝子座にloxP特異的リコンビナーゼCreをコードする遺伝子を組み換えることで皮質上皮細胞特異的に遺伝子を改変させるマウスを作出するとともに、髄質上皮細胞の亜集団に発現されるケモカインCCL21の遺伝子座に赤色蛍光タンパク質dsTomatoをコードする遺伝子を組み換えることでCCL21を発現する髄質上皮細胞特異的に蛍光検出するマウスの作製を進めた。更に、モデル自己抗原ovalbuminをAire遺伝子座に組換えたマウスを作出しovalbumin応答性TCRトランスジェニックマウスおよびAire欠損マウスと交配させることによって、Aire発現細胞による自己抗原応答性T細胞の胸腺内排除には必ずしもAire依存的な下流分子機構が必要ではないことを明らかにした。
