Cigarette smoke induced DDR and airway inflammation in human samples. (A) Representative examples of immunohistochemistry of gH2AX expression in the lungs of human specimens. (B) Percentages of cells expressing gH2AX in smokers and non-smokers. (C) Representative examples of immunohistochemistry of IL-17 expression in human lung tissue. (D) Percentages of cells expressing IL-17 in smokers and non-smokers. (E) The relationship between IL-17 expression and DDR in lung specimens. (n = 6 mice per group in each experiment. Image magnification of immunohistochemistry: 10 × 100. Data are presented as means ± SEM, *** p < 0.001).
