Outline of Final Research Achievements

Interleukin-15 (IL-15) is an important cytokine for development and homeostasis of the immune system, and we previously identified a variety of IL-15-expressing cells in vivo. However, the local functions of these IL-15-expressing cells is poorly understood. To address this question, we established eleven types of IL-15 conditional knock out (cKO) mice. This study revealed the local function of IL-15-expressing cells in thymus, bone marrow, lymph node, liver and intestine by using these IL-15 cKO mice. IL-15-expressing cells contribute to the development, maturation, homeostasis and response of immune cells in vivo. Furthermore, IL-15-expressing cells in thymus also contribute to the anti-tumor immunity.

Academic Significance and Societal Importance of the Research Achievements

インターロイキン15(IL-15)は免疫細胞に重要な働きをしている。本研究において、IL-15コンディショナルノックアウトマウスなどを独自に作製した。これらのIL-15関連マウスモデルを用い、生体内の様々な組織におけるIL-15産生性免疫微小環境の局所機能を明らかにした。また、抗がん免疫機能について、胸腺内IL-15産生性免疫微小環境も重要であることを示唆した。
本研究によって、IL-15による免疫細胞の制御機構および生体防御機構に対する新たな知見を得ることができた。がんや慢性炎症、自己免疫疾患などに対するIL-15を標的とする治療薬や治療法の開発に有用であると考えられる。
