Perturbed development of intestinal CD3−GFP+ cell subsets in Ncr1GFP/+ mice that overexpress IL-15 in the intestinal epithelium. (A) NK1.1 versus CD127 expression on gated CD3−GFP+ cells from small intestinal (SI) LPL and intraepithelial (IEL) compartments. Subset frequencies are indicated. Representative results from one out of six independent experiments are shown. (B) Absolute numbers of total CD3−NKp46+ cells and CD127/NK1.1 subsets from small intestinal LPLs in WT and IL-15 Tg mice (n = 5–8 mice of each genotype analyzed). Only CD127−NK1.1+ cells were significantly increased in IL-15 Tg mice. Values are presented as means ± SD. (C) RORγt expression in intestinal CD3−NKp46+ subsets in WT (bold line) and IL-15 Tg mice (shaded histogram). The dotted line depicts staining of CD3−NKp46+ cells from Rorc−/− mice. (D) IL-22 production from intestinal CD3−NKp46+ subsets in WT and IL-15 Tg mice. Results indicate frequencies from one out of three independent experiments.
