Cell count and cytokine levels of bronchial alveolar lavage (BAL). Total and differential cell counts and ELISA were performed on BAL fluid isolated from sedentary controls (controls), exercise-only (EX), Pseudomonas-only (PS), and PS + EX groups. n = 2 × 10/group. Total cells (a), neutrophils (b), lymphocytes (c), and the levels of IL-1β (d), IL-6 (e), CXCL1 (f), TNF-α (g), and IL-10 (h) were assessed. * p < 0.05, ** p < 0.01, *** p < 0.001.
