Repeated CS exposure increases KC, MIP-2, TNF-α and IL-1β in BAL fluid. Mice were repeatedly exposed to CS for up to 10 days and the levels of KC (A), MIP-2 (B), TNF-α (C) and IL-1β (D) in the BAL fluid were determined by ELISA. Data represent the average concentration per ml BAL fluid ± SEM from eight mice. Statistical significance: * = p < 0.05; ** = p < 0.01; *** = p < 0.001.
