The expression level of immunosuppressive agents in hAECs. hAECs were cultured in the presence or absence of LPS for 6 h. The effects of LPS on the expression of PGE2 synthase, TGF-β1 and IL-10 in hAECs were evaluated by real-time PCR assay. All data are shown as mean ± SE. The depicted results are representative of ten independent experiments. Asterisk indicates that the difference in the expression levels are statistically significant. NS indicates that the difference in the expression levels is not statistically significant. *p < 0.05, ***p < 0.001
