Blimp-1 supports Th2 development through suppression of Bcl6. Analysis of lungs isolated from control, Bcl6CD4Cre (Bcl6f/f CD4Cre+), Blimp-1CD4Cre (Blimp-1f/f CD4Cre+), or doubleKOCD4Cre (Bcl6f/f Blimp-1f/f CD4Cre+) animals i.n. immunized with HDM. (A) PAS staining (scale bar, 100 µm). (B) Percent of eosinophils in the BAL. (C) Percent of Th1 (IFN-γ+ T-bet+), Th2 (IL-13+ GATA3+), and T reg (FoxP3+) cells isolated from lungs (gated on live CD4+TCRβ+ [T reg], and FoxP3 [non-T reg]). (D) Total IgE in serum. (E) Flow analysis of IL-10 and FoxP3 T cells isolated from lungs of indicated mice after HDM-induced allergic asthma. Gated on live TCRβ+ CD4+. (F) Percent and geometric (Geo) MFI of IL-10+ cells in effector (CD4+TCRβ+FoxP3) or T reg (CD4+TCRβ+FoxP3+) cells in lung. Data from B–F are pooled from three experiments with 7–17 total mice per group, mean ± SD. Kruskal–Wallis one-way ANOVA. *, P < 0.05; **, P < 0.01; ***, P < 0.001; ****, P < 0.0001.
