CB1 activation eliminates TRPV1 induced increases in IL-8 release. HCEC were pretreated with Anandamide (AEA; 10 μM) and/or AM251 (5 μM) for 1 h and then incubated with capsaicin (CAP; 10 μM). At the end of the incubation period, the levels of IL-8 were determined by ELISA. The data represent the means ± SEM (n=3, *P < 0.01).
