Mice received oropharyngeal bleomycin or saline on day 0. Mice were maintained on low, regular, or high NaCl diets for 21 days. A) Lung sections were stained for CD45 to detect all leukocytes, B) CD3 to detect T lymphocytes, C) CD11c to detect resident alveolar macrophages and dendritic cells, D) CD11b to detect blood and inflammatory macrophages, E) Ly6c to detect inflammatory macrophages, or F) CD206 to detect macrophages and dendritic cells. Values are mean ± SEM, n = 3–4 per group. *p < 0.05, ** p < 0.01 (1-way ANOVA, Tukey’s test).
