Cadmium (Cd)–promoted infiltration of monocytes and lymphocytes in lung. The lung tissues (A–C) and bronchoalveolar lavage (BAL) fluid (D–F) from individual mice were collected from individual mouse of each group (Figure 1). Monocytes (F4/80⁺CD11c⁻CD11b⁺Ly6C^hiSiglecF⁻) and CD4 (CD3, CD4) and CD8 (CD3, CD8) lymphocytes were analyzed by flow cytometry, and quantified cells are shown in bar graphs using an unpaired two-tailed t-test. Error bars indicate means ± SEM of cell counts from individual animals (A–F). n = 8 per group (A–F). ^∗P < 0.05 versus control (cont); ^†P < 0.05 versus respiratory syncytial virus (RSV) only group.
