Figure 3From: IL-17A is essential to the development of elastase-induced pulmonary inflammation and emphysema in miceCellular composition in bronchoalveolar lavage (BAL) fluid after intratracheal instillation of PPE or saline. BAL fluid was obtained as described in Methods. Data represent the mean ± SEM (n=12 in each group). (A) Cellular composition in BAL fluid on day 4 after intratracheal instillation of PPE or saline. *p<0.01 compared to WT saline and IL-17A−/− saline. #p<0.05 versus WT PPE. ##p<0.01 versus WT PPE. (B) Cellular composition in BAL fluid on day 21 after intratracheal instillation of PPE or saline. *p<0.05 compared to WT saline and IL-17A−/− saline.Back to article page
