Elevated expression of IL-33 in mice with ARDS. (a) The protein level of IL-33 in peripheral blood was measured by ELISA. (b) The mRNA expression of IL-33 in the lung was measured by qRT-PCR. (c) The level of IL-33 protein in lung tissue was measured by Western blotting. The data are expressed as the means ± SDs. Significant differences are shown by ^∗P < 0.05, ^∗∗P < 0.01, and ^∗∗∗P < 0.001 by unpaired Student's t-tests comparing the normal WT controls and ARDS groups. N = 5 for each group, and three independent repeated experiments were carried out.
