Enteric neurons and immune cells shape anti-helminth immunity.

Wang et al. recently reported that during helminth infection, innate lymphoid cell (ILC)-derived IL-13 is sensed by gut neurons, which in turn secretes CGRP to inhibit ILC2 proliferation and anti-helminth responses. Hence, this study demonstrates a bidirectional crosstalk between enteric neurons and immune cells that regulates type-2 immunity.
