Figure 2

Morphometric assessment performed on day 21 after instillation of PPE or saline. Representative photographs of lungs of WT mice treated with saline (A), IL-17A−/− mice treated with saline (B), WT mice treated with PPE (C), and IL-17A−/− mice treated with PPE (D) groups. (E) Mean linear intercepts (Lm) values of alveoli. Lm values were obtained as described in Methods. Bar = 200 μm. 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.
