Fig 3. Alveolar macrophages in T-CNT-expose mice.

(A) CD11b and F4/80 expression of mononuclear cells in BALF from control and T-CNT-exposed mice were detected by flow cytometric analysis. The results are representative of each group. F4/80⁺CD11b^low and F4/80⁺CD11b^high populations are shown. (B) The proportion of F4/80⁺CD11b^low and F4/80⁺CD11b^high macrophage in BALF from control and T-CNT-exposed mice were detected by flow cytometric analysis. Data are presented as the average ± SD of five mice of each group. *p < 0.05, **p < 0.005, vs controls.
