1.はじめに

 脂質メディエーターは,増殖因子やサイトカインなどの生理活性蛋白質と異なり,直接遺伝子にコードされていない1).つまり,脂質メディエーターの局在は,生合成や分解などの代謝経路や輸送体による細胞外への放出経路により時空間の制御を受ける.さらに,脂質メディエーターは,標的細胞に発現する特異的な受容体(複数のサブタイプを有する場合が多い)や共役するシグナル伝達系の組合わせにより,多様な器官形成や多彩な生理機能の制御に貢献している.

 本稿では,スフィンゴシン-1-リン酸(sphingosine-1-phosphate;S1P)の循環器系や免疫系における役割に焦点を絞り最近の知見を紹介する.
