N-arachidonoyl ethanolamine (AEA) and 2-arachidonoyl glycerol (2-AG) are endogenous cannabinoids binding to the cannabinoid receptors CB1 and CB2 to modulate neuronal excitability and synaptic transmission in primary afferent neurons. To investigate the compartmentalization of the machinery for AEA and 2-AG signalling, we studied their partitioning into lipid raft fractions isolated from a dorsal root ganglion X neuroblastoma cell line (F-11).
