Levels of several inflammatory cytokines in culture medium of primary AMs treated with LPS. (a-d) Levels of IL-33 (a), TNF-α (b), MMP2 (c), and MMP9 (d) in the culture medium of primary AMs treated with or without LPS. (e) Protein levels of ST-2 and IL-1RAP in primary AMs treated with or without LPS. (f) Protein levels of p-STAT3 and STAT3 in primary AMs treated with or without LPS. Data are shown as means±SD (three independent repeats). Two-tailed t test was used in the statistical analyses. ** p < 0.01, *** p < 0.001 vs. control
