LY-2183240 enhances reward-seeking behavior with inducing neuronal excitation and early apoptosis in mouse

Abstract Cannabinoids interact with cannabinoid receptors, influencing diverse central nervous system (CNS) and peripheral functions, including anxiety, depression, and cognition. CB1 and CB2 receptors modulate signaling cascades via G-protein coupling, with anandamide acting as an endogenous ligand for CB1 receptors. LY-2183240, a putative endocannabinoid transport blocker, elevates brain anandamide levels, showing therapeutic potential in pain management and alcohol-related behaviors. LY-2183240 enhances neuronal excitability and is classified as a new psychoactive substance (NPS). However, its precise cellular mechanisms within the CNS
