FIG 3.

MARCO and TLR-2 expression is not impaired on monocytes or macrophages from mir155KO mice. The surface expression of MARCO and TLR-2 on nasal macrophages (F4/80⁺) (A, D), and Ly6C⁺ blood monocytes subsets (Ly6C^hi, HI; Ly6C^lo, LO) (B, E) in uninfected mice (D0) and over the course of colonization and elicited peritoneal macrophages (C, F) are shown. WT mice, squares with solid lines; mir155KO mice, circles with dashed lines. n = 3 to 5 per time point per group. Statistical significance was determined by Wilcoxon rank sum test. dMFI, mean fluorescent intensity minus isotype control level. *, P < 0.05.
