Loftén A, Adermark L, Ericson M, Söderpalm B (2023) Regulation of ethanol-mediated dopamine elevation by glycine receptors located on cholinergic interneurons in the nucleus accumbens. Addict Biol 28(12):e13349. doi: 10.1111/adb.13349 PMID: 38017639
Objective: The aim of this study was to explore the role of glycine receptors (GlyRs) on cholinergic interneurons (CIN) in sustaining extracellular dopamine levels and in ethanol-induced dopamine release.
Summary: Alcohol use disorder is one of the major psychiatric disorders worldwide. Ethanol reward is one of the many factors contributing to the disorder. The rewarding and reinforcing properties of ethanol have been linked to activation of the mesolimbic dopamine system, an effect that involves glycine receptors (GlyRs) in the nucleus accumbens. The study suggests that CIN are not important for GlyR-mediated regulation of basal dopamine output, but that CIN ablation blunts the ethanol-induced dopamine release by reducing the release of GlyR agonists.
Usage: CIN were ablated by Anti-ChAT-SAP administered locally in the nucleus accumbens of male Wistar rats. Rabbit-IgG-SAP was used as a control. Microinfusion was performed unilaterally into the nAc at a concentration of 0.5 ug/ul at 0.05 ul/min for 10 min for a total of 0.5 ul.
