text_1: Crosstalk between dendritic cells (DCs) and innate lymphoid cells (ILCs) is important in the regulation of intestinal homeostasis.
text_2: TNF-α produced by CD103(-)CD11b(+) dendritic cells synergized with IL-23 to drive IL-17A production by ILCs, demonstrating a previously unrecognized layer of cellular crosstalk between dendritic cells and ILCs. Crucially, T-bet also suppressed the expression of IL-7R, a key molecule involved in controlling intestinal ILC homeostasis.
