Effects of PGA2, PGE2, PGD2, PGF2α, PGJ2, and PGI2 on LPS-induced sICAM1 and IL-8 production. Pulmonary EC were treated with indicated PG (0.5 µM, 15 min) followed by addition of LPS (300 ng/ml, 6 h). Secretion of inflammation markers into the culture medium was detected by ELISA assays. A: sICAM1. B: IL-8. n = 3. *P < 0.05 vs. LPS.
