The expression of CD68+ macrophages (A-C), CD86+ CD68+ macrophages (D-F), and CD11c+ MHCIIhi dendritic cells (G-I) are reported as percent of large cells in the BALF (A, D, G), total cells in the BALF (B, E, H), and total cells in digested whole lung tissue (C, F, I) following treatment with IFNγ or PBS. Mean and SEM are reported with ≥ 5 mice per group; a one-way ANOVA describes group differences: *p<0.05; ***p<0.001.
