abstract：:The precise mechanism by which the cellular uptake of the endocannabinoid anandamide (AEA) occurs has been the source of much debate. In the current study, we show that neuronal differentiated CAD (dCAD) cells accumulate anandamide by a process that is inhibited in a dose-dependent manner by N-(4-hydroxyphenyl)arachid...
