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

Figure 5

The results obtained in the evaluation of phosphorylated STAT3 (p-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 p-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 p-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. ; .
