Alcohol use disorder (AUD) is characterized by alcohol use coupled with chronic relapse and involves brain regions including the bed nucleus of the stria terminalis (BNST). Here, we explore whether a subpopulation of BNST neurons, somatostatin (SST) expressing GABAergic neurons, play a role in an animal model of binge-like alcohol consumption, the Drinking in the Dark (DID) model. Chemogenetic activation of BNST SST neurons reduced binge alcohol consumption in female but not male SST-Cre mice, while inhibition of these neurons in the same mice had no effect. In addition, chemogenetic activation of these neurons did not cause apparent changes in models of anxiety-like behavior in either sex. Basal SST cell counts and intrinsic excitability of SST neurons were compared to attempt to understand sex differences in DREADD-induced changes in drinking, and while males had a greater number of BNST SST neurons, this effect went away when normalizing for total BNST volume. Together, these results suggest SST neurons in the BNST should be further explored as a potential neuronal subtype modulated by AUD, and for their therapeutic potential. |
