MUC5B determinations in infant lungs. (A) Representative MUC5B western blot showing Pneumocystis negative (Pc−) and Pneumocystis positive (Pc+) infant lung samples. Actin was measured as loading control. (B) Graph plot of MUC5B western blot quantification levels. Each bar represents the mean +/− SD of 8 observations normalized by actin. P. value was calculated using Mann-Whitney test. *** indicates P = 0.0002.
