ABSTRACT
Innate lymphoid cells (ILCs) are lymphocyte-like cells that lack T cell or B cell antigen receptors and mediate protective and repair functions through cytokine secretion. Among these, type 2 ILCs (ILC2 cells) are able to produce type 2 cytokines. We report the existence of an inflammatory ILC2 (iILC2) population responsive to interleukin 25 (IL-25) that complemented IL-33-responsive natural ILC2 (nILC2) cells. iILC2 cells developed into nILC2-like cells in vitro and in vivo and contributed to the expulsion of Nippostrongylus brasiliensis. They also acquired IL-17-producing ability and provided partial protection against Candida albicans. We propose that iILC2 cells are transient progenitors of ILCs mobilized by inflammation and infection that develop into nILC2-like cells or ILC3-like cells and contribute to immunity to both helminths and fungi.
