a Simplified scheme of PRDM5-MAGL-2-AG-CB1R pathway in normal mice. b Simplified scheme of PRDM5-MAGL-2-AG-CB1R pathway in mice under ketamine conditioning paradigm. Ketamine represses Mgll gene transcription by enhancing the binding of PRDM5 at the promoter of gene Mgll, leading to the decreased MGL expression and 2-AG hydrolysis. Consequently, increased 2-AG activates CB1R signaling, resulting in ketamine addiction-related dendritic remodeling and behaviors.
