Tissue-resident Eomes+ NK cells are the major innate lymphoid cell population in human infant intestine

Abstract

Innate lymphoid cells (ILC), including natural killer (NK) cells, are important innate immune regulators. Here the authors show that, in human infant intestines, CD103+Eomes+ NK cells are the predominant ILC population, but are replaced gradually by Eomes+ T cells, while NKp44+ NK cells persist in adult intestines.
