Outline of Final Research Achievements

Group 2 innate lymphoid cell (ILC2) play important roles in asthma and parasitic worm infection. ILC2 development heavily depends on IL-7, however, the in vivo source of IL-7 required for ILC2 development is unidentified. In other words, it is unknown where and how ILC2s are generated in vivo.
In this study, we analyzed immune microenvironment essential for ILC2 development. By using IL-7 conditional knockout mice and IL-7 reporter mice, we narrowed down the candidate cells that support ILC2 development.

Academic Significance and Societal Importance of the Research Achievements

本研究は、IL-7遺伝子座に蛍光タンパクGFPをノックインしたマウス及び、ストローマ細胞特異的IL-7遺伝子欠損マウスを用いて、ILC2の分化の場となるIL-7産生性の局所的環境(ニッチ)を明らかにすることを目的とした。本研究成果により、気管支喘息や寄生虫感染症などの疾患に対して、ニッチ細胞特異的にIL-7産生を薬物で調節し、自然リンパ球の発生をコントロールする治療法の開発が可能になると予想される。
