Reduced alternatively activated M2 macrophage numbers in total lung of AdOSM-treated RELMα–/– mice. (A) Enumeration of eosinophils, lymphocytes, macrophages and neutrophils recovered from BAL fluid. (B) Gating strategy (left panel) of F4/80+ macrophages and total CD38+ M1 or CD206+ M2 macrophages (right panel). (C) Gating strategy (left panel) and total IFNγ-producing CD4+ T cells. Data are represented as mean ± SEM (n = 5 mice/group). Statistical significance was determined by two-way ANOVA with Tukey’s post hoc test (*
p < 0.05, **
p < 0.01, ***
p < 0.001, ****
p < 0.0001 between indicated groups).
