Hyperoxia induced Th17 cell response in BPD mice. A Representative FACS analysis showing the gating strategy used to identify CD45⁺CD4⁺IL-17 A⁺Th17 in lung of BPD mice. B Representative results of Th17 cells detected by flow cytometry in lung tissues from the normoxia and hyperoxia groups. C Percentage of Th17 cells detected by flow cytometry in lung tissues from the normoxia and hyperoxia groups. D–F IL-17 A, IL-17 F, and IL-22 levels in the blood serum and lung tissues were assessed in the normoxia and hyperoxia groups. Data presented are the mean ± SD (n = 6); ** P < 0.05 vs. normoxia group
