Cytokine and chemokine levels in the BAL fluid and lung homogenates. (A) KC, MIP-2, and IL-1β levels in BAL fluid. BAL fluid was obtained from the same groups as described in Figure 3A. Data represent the mean ± SEM (n=12 in each group). *p<0.01 compared to WT saline and IL-17A−/− saline. #p<0.05 versus WT PPE. ##p<0.01 versus WT PPE. (B) IL-17A levels in lung homogenates on day 4 after intratracheal instillation of PPE or saline. Data represent the mean ± SEM (n=8 in each group). (C) IL-17A levels in lung homogenates on day 21 after intratracheal instillation of PPE or saline. Data represent the mean ± SEM (n=8 in each group).
