Fig. 6From: Dual action of the cannabinoid receptor 1 ligand arachidonyl-2′-chloroethylamide on calcitonin gene-related peptide releaseGraphical illustration of the interaction of CB1 and TRPV1 by cannabinoids. A ACEA activates both TRPV1 and CB1 in a native setting, leading to no observed inhibition. B when TRPV1 is inhibited, activation of CB1 leads to an attenuation of the CGRP releaseBack to article page
