Δ9-Tetrahydrocannabinol changes the brain lipidome and transcriptome differentially in the adolescent and the adult.

ABSTRACT: Exposing the adolescent brain to drugs of abuse is associated with increased risk for adult onset psychopathologies. Cannabis use peaks during adolescence, with largely unknown effects on the developing brain. Cannabis' major psychoactive component, Δ9-tetrahydrocannabinol (THC) alters neuronal, astrocytic, and microglial signaling. Therefore, multiple cellular and signaling pathways are affected with a single dose of THC. The endogenous cannabinoids (eCBs), N-arachidonoyl ethanolamine (AEA) and 2-arachidonoyl glycerol (2-AG) are members of an interconnected lipidome that includes an emerging class of AEA structural analogs, the lipoamines, additional 2-acyl glycerols, free fatty acids, and prostaglandins (PGs). Lipids in this lipidome share many biosynthetic and metabolic pathways, yet ha
