Outline of Final Research Achievements

Using Rag2-/- mice lacking adaptive immune cells and γc-/-Rag2-/- mice lacking all lymphocytes, we have revealed that group 2 innate lymphoid cells (ILC2) and group 3 innate lymphoid cells (ILC3) from small intestine (SI-ILC2 and SI-ILC3, respectively) and IL-2 derived from those SI-ILCs are involved in the diet-induced obesity. Contrary to SI-ILC2, ILC2 derived from white adipose tissue (WAT-ILC2) suppressed adipocyte differentiation in an in vitro culture system, indicating that SI-ILC2 and WAT-ILC2 have different functions.

Academic Significance and Societal Importance of the Research Achievements

肥満は様々な生活習慣病の背景となることから、社会的な問題となっている。我々の研究は過去10年の間にその存在が明らかにされた、抗原受容体を持たないリンパ球である自然リンパ球が肥満の誘導に関わることを明らかにした。さらに、寄生虫に対する感染防御やアレルギー性炎症に関係すると考えられてきた2型自然リンパ球(ILC2)が腸管と脂肪組織において異なる性質を持つこと、すなわち、腸管のILC2は肥満を誘導するのに対し、脂肪組織のILC2が脂肪細胞の分化を抑制する点は興味深い。今後これらの活性の分子機構の詳細を明らかにすることで肥満の予防や治療に繋がる新たな発見が期待される。
