Cytokine and chemokine dosages in lung homogenate were significantly lower at 48 hours after pneumonia induction, in the exercised group compared with control (interleukin [IL]-1β: 31.2 ± 65.4 vs. 13.1 ± 56.1 μg/g of lung, p = 0.04; tumor necrosis factor-α: 37 ± 15.14 vs. 94.35 ± 27.5 μg/g of lung, p = 0.046; IL-6: 6.2 ± 2.2 vs. 25.7 ± 13.7 μg/g of lung, p = 0.047; and IL-10: 2.254 ± 0.445 vs. 5 ± 1 μg/g of lung, p = 0.02; Fig. 3). This evidence concerns the gene TNF and pneumonia.
