Research Abstract

CD45は免疫細胞に発現する膜型フォスファターゼであり、リンパ球の分化増殖に重要な機能を担っている。CD45のフォスファターゼ活性化がどのように制御されているかについては長年議論が続いている。一方、T細胞の活性化に重要な機能を担う抗原提示細胞には様々な免疫制御分子が発現しており、T細胞の活性化制御に深く関わっている。我々は、抗原提示細胞に発現する免疫制御分子としてPILRを同定した。PILRは細胞内領域に抑制化シグナルを伝達するITIM配列を持った細胞表面分子である。我々はPILRの解析により、可溶型CD45が抑制化レセプターPILRに特異的に会合することを発見した。そこで、本研究では、PILRによるCD45の機能制御がT細胞の自己認識制御にどのように関与しているかを解明し、新たなT細胞自己応答制御機構を解析した。その結果、抗原提示細胞の発現するPILRがT細胞の増殖を顕著に誘導することが明らかになり、PILRによるCD45の機能制御がT細胞応答制御に重要であることが判明した。また、PILRは顆粒球に発現しており、顆粒球上のCD45とcisの相互作用をし、抑制化シグナルを伝達している可能性が明らかになった。特に、PILRの非存在下では顆粒球の遊走能が顕著に亢進しており、Erkのリン酸化も更新することが明らかになった。以上より、PILRはリガンド分子とcisまたはtransの双方の相互作用によって免疫応答を負に制御していることが明らかになった。
