Effect of CS exposure and BMP-6 deficiency on inflammatory cell numbers in lung tissue. Macrophages (a), CD11b⁺ dendritic cells (DCs) (b), CD4⁺ CD69⁺ T lymphocytes (c), and CD8⁺ CD69⁺ T lymphocytes (d) in lung tissue of WT and BMP-6-deficient mice upon 4 weeks exposure to air or CS. All cell types were enumerated by flow cytometry. Data are expressed as mean ± SEM (n = 8−12 animals/group; *P < 0.05, **P < 0.01). Data shown are representative of two independent experiments
