Endocannabinoid Activity Remodulation for Psychosis Liability in Youth

"Palmitoylethanolamide (PEA) is an N-acylethanolamine (AE), produced on demand by different cell types as a response to actual or potential damage, proven to down-regulate central and peripheral activity of mast cells and non-neuronal cells (e.g., astrocytes, microglia) and to exert protective functions against glutamate neuro-toxicity, accounting for its naturally-occurring anti-inflammatory, analgesic, and anticonvulsant properties. Due to the shared pharmacodynamic properties, PEA is considered as the endogenous equivalent of Cannabidiol (CBD). A growing body of literature has confirmed the role of PEA in most neurobiological mechanisms underpinning several neuropsychiatric conditions both in clinical and preclinical settings. The effect of PEA over neuroinflammation and glutamate signaling may represent a promising biobehavioral mechanism underlying the clinical utility of its oral supplementation in CHR state."
