The aryl hydrocarbon receptor: a sentinel safeguarding the survival of immune cells in the gut

Immunity. 2012 Jan 27;36(1):5-7. doi: 10.1016/j.immuni.2012.01.004.

Abstract

Innate lymphoid cells (ILCs) regulate the epithelial barrier function and immunity in the gut. How ILC numbers are maintained is unknown. In this issue of Immunity, Qiu et al. (2012) report that the transcription factor aryl hydrocarbon receptor controls survival and function of gut-residing ILCs.
