Aryl Hydrocarbon Receptor Signaling Cell Intrinsically Inhibits Intestinal Group 2 Innate Lymphoid Cell Function

The aryl hydrocarbon receptor (Ahr) promotes ILC3 maintenance and function. Li et al. report that Ahr restricts intestinal ILC2 function in a cell-intrinsic manner, suggesting a central role for gut adaptation of Ahr expression in regulating the ILC2-ILC3 balance.
