Research Interests or Current Research Focus
Our lab focuses on the molecular mechanisms of inflammation and immune regulation, preliminary based on intestinal immunity context. We study the function of innate immune system and adaptive immune system under the steady state and inflammatory status, particularly the cross-talk among the immune cells in the intestine; the cross-talk between immune cells and commensals, and the significance of intestinal immunity to diseases.

1) Examine the molecular mechanisms of the development of group 3 Innate lymphoid cells (ILC3).
2) Examine the cross-talk between ILC3 and other immune cell types.
3) Determine the relationship between ILC3 and commensals.
4) Determine the significance of ILC3 to diseases.

Major Research Achievement
Group 3 Innate lymphoid cell (ILC3) is important for maintaining intestinal immune surveillance and immune regulation. We have found that aryl hydrocarbon receptor (Ahr), a nuclear transcription factor, is essential for the development and function of ILC3. Particularly, Ahr is required for maintenance of adult ILC3s and their IL-22 production, which is important for the clearance of pathogens in the intestine. In addition, ILC3 can inhibit the expansion of segmented filamentous bacteria (SFB), a commensal that can induce Th17 cell mediated inflammatory responses. Thus, ILC3 also plays immune regulatory role by inhibiting autoimmunity. Besides, Ahr regulates the function of Tregs through multiple mechanisms. We are interested in understanding the intricate mechanisms of inflammation and immune regulation, mediated mainly by ILC3 and its cross-talk with other cell types.
