Abstrakt: | Background and Purpose: Muscarinic acetylcholine receptors mediate alcohol consumption and seeking in rats. While M Experimental Approach: In Indiana alcohol-preferring (iP) male rats, we examined Chrm4 (M Key Results: Long-term alcohol and abstinence dysregulated the expression of genes for muscarinic receptors in the vSub, not in the VTA. Chrm4 was down-regulated following long-term alcohol and abstinence, while Chrm5 was up-regulated following long-term alcohol consumption. Consistent with these data, a positive allosteric modulator (VU0467154) of intra-vSub M Conclusion and Implications: Collectively, our data highlight alcohol-induced cholinergic dysregulation in the vSub and distinct roles for M (© 2021 The British Pharmacological Society.) |
