Abstract

Alcohol use disorder (AUD) is characterized by compulsive binge alcohol intake, leading to various health and social harms. Protein Kinase C epsilon (PKCε), a specific family of PKC isoen-zyme, regulates binge alcohol intake, and potentiates alcohol-related cues. Alcohol via upstream kinas-es like the mammalian target to rapamycin complex 1 (mTORC1) or 2 (mTORC2), may affect the activities of PKCε or vice versa in AUD. mTORC2 phosphorylates PKCε at hydrophobic and turn motif, and was recently reported to be associated with alcohol-seeking behavior, suggesting the potential role of mTORC2-PKCε interactions in the pathophysiology of AUD. mTORC1 regulates translation of synaptic proteins involved in alcohol-induced plasticity. Hence, in this article, we aimed to review the molecular composition of mTORC1 and mTORC2, drugs targeting PKCε, mTORC1, and mTORC2 in AUD, upstream regulation of mTORC1 and mTORC2 in AUD and downstream cellular mechanisms of mTORCs in the pathogenesis of AUD.
