Increased neutrophils and macrophages in lungs of polymeric Ig receptor null (pIgR−/−) mice. Absolute number of (A) neutrophils and (B) macrophages in lungs of wild-type (WT) and pIgR−/− mice; n = 3–6 mice/group; *P < 0.05 (t test). Percentage of (C) neutrophils and (D) macrophages relative to CD45+ immune/inflammatory cells in lungs of 8- to 9-month-old WT and pIgR−/− mice; n = 3–6 mice/group; *P < 0.05 (t test). From CD45+ cells, alveolar macrophages were defined as CD11chiF4/80hiCD103-CD11b− and neutrophils were defined as CD11b+/Ly6G+. n.s. = not significant.
