a Cells in BALF were stained with Gr1-PE, CD11b-FITC, and CD3-APC and then analyzed by flow cytometry. Cytokines in serum (b) and BALF (c) from each group were detected by ELISA. d Relative mRNA expression of IL-1β, IL-6, and TNF-α was measured by qPCR. Data are expressed as the mean ± S.E.M., n = 6 mice per group, *P < 0.05 vs the IR group.
