Outline of Final Research Achievements

Innate lymphoid cells (ILCs) are newly described immune lymphoid cells but do not express antigen-specific receptors. ILC type 2 (ILC2) cells have important functions in innate immune responses to helminth infection and in the regulation of allergic inflammation in the lung. ILC2 cells are abundant in colonic lamina propria, however, the regulatory mechanisms of the development and the role of ILC2 cells in the intestine are poorly understood. We identified that gut ILC2 expressed high level of Il4, H2-Ab1 (MHC class II) and Apoe compared with lung ILC2. We also discovered Il4 expression in gut ILC2 is dependent on dietary vitamin B1. These results indicate that gut ILC2 exhibit unique development programs and functions.
