IL-15 sustains IL-7R-independent ILC2 and ILC3 development

Abstract

ILC2 and ILC3 are generally thought to require IL-7. Here the authors use IL-7 ko mice and provide side-by-side comparison of ILCs from different tissues to show that IL-7 signalling is not required for intestinal ILC maintenance or function and that IL-15 can compensate for absence of IL-7.
