IL-33 deficiency alleviated pulmonary histopathology in mice with ARDS. (a) Representative images of HE staining of lung sections; the magnification of histological images is ×200. (b) Lung injury scores were measured by the Smith method. The data are expressed as the means ± SDs. Significant differences are shown by ^∗P < 0.05, ^∗∗P < 0.01, and ^∗∗∗P < 0.001 by one-way ANOVA followed by Bonferroni's post hoc test comparing the WT control, LPS, LPS+rmIL-33, and LPS+IL-33^−/− groups. N = 3‐5 for each group, and three independent repeated experiments were carried out.
