Cadmium (Cd) intake enhanced proinflammatory cytokine levels in the lung after respiratory syncytial virus (RSV) infection. Inflammatory cytokines were determined in lung lysates and bronchoalveolar lavage (BAL) fluids and analyzed for interferon (IFN)-γ (A and E), IL-1β (B and F), IL-6 (C and G), and IL-4 (D and H) quantitation by corresponding cytokine enzyme-linked immunosorbent assay kits. Data are expressed as means ± SEM (A–H). n = 8 per group (A–H). ^∗P < 0.05 versus control (cont).
