Sorting strategy for ILC2 and NK cells from lung and liver. (A and B) ILC2 were sorted as Lin (CD3 and CD19)⁻CD127⁺Tbet⁻Gata3⁺RORγt⁻; NK cells were sorted as Lin⁻CD127⁻NK1.1⁺Tbet⁺ from lung (A) and liver (B) of both control and IL-33–treated mice. The histograms depicted the Gata3 expression against cell count.
