intestine (A and B), lung (C and D), and mLN (E and F) from ChAT-eGFP reporter
mice analyzed on Day 7 of N. brasiliensis infection, stained

show representative ChAT-eGFP+ ILC2s. Data are representative of two
independent experiments. Scale bars = 100 μm in (A), (C) and (E), and 30
μm in (B), (D) and (F).
