Fig. 3: Lung lineage-negative CD25+CD127+ST2+ ILC2s in RV-infected 6-day-old mice.

a and b Six-day-old wild-type C57BL/6 mice were inoculated with sham, RV-A1B, or RV-C15. Four, 7, 10 or 14 days later, live ILC2s were identified as lineage-negative (upper panels), CD25+ and CD127+ (middle panels, both dot plot and contour plots are shown) and ST2+ (lower panels). ILC2s were quantified as a percentage of lin− cells and as a total ILC2s per lung. b, time course of viral-induced lung lineage-negative CD25+ CD127+ST2+ ILC2s (n = 6–9, mean ± SEM from two experiments for day 7; n = 3–4, mean ± SEM from one experiment for days 4, 10, and 14, *different from sham, †different from RV-A1B, p < 0.05, one-way ANOVA).
