Exercise Inhibits the Effects of Smoke-Induced COPD Involving Modulation of STAT3

Figure 4

The results obtained in the evaluation of total STAT3 expression in airway epithelial cells (a), peribronchial leukocytes (b), and parenchymal leukocytes (c) in the groups: control, exercise (Exe), chronic obstructive pulmonary disease (COPD), and chronic obstructive pulmonary disease submitted to aerobic exercise (COPD+Exe). Representative photomicrographs of lung slices focusing on epithelial STAT3 expression from the (d) control, (e) exercise, (f) chronic obstructive pulmonary disease, and (g) chronic obstructive pulmonary disease submitted to aerobic exercise (COPD+Exe) groups and on parenchyma STAT3 expression from the (h) control, (i) exercise (Exe), (j) chronic obstructive pulmonary disease (COPD), and (k) chronic obstructive pulmonary disease submitted to aerobic exercise (COPD+Exe) groups. Scale bars: 25 mm. Data are presented as means and SD. ; .
