Different concentrations of Dex (10 nM, 100 nM, 1000 nM, and 10,000 nM) can attenuate the inflammatory response induced by IL-1β (10 ng/mL). IL-1β and Dex were added at the same time as the stimuli. a. mRNA levels of the inflammatory genes were determined via RT-PCR. b. Levels of the inflammatory cytokines were determined via ELISA. Data are presented as mean ± SD. N = 3. *P < 0.05 vs. A549 0 h, **P < 0.01 vs. A549 0 h, ##P < 0.01. Dex: dexamethasone, IL-1β: interleukin-1β
