CRH neurons receive two forms of GABAergic inhibition, phasic and tonic, but the specific roles of these two types of signaling have not yet been studied in this cell type. Our lab recently demonstrated a role for the GABAAR δ subunit in the tonic GABAergic regulation of CRH neurons. Using a floxed Gabrd mouse model established in our laboratory, we generated mice in which the GABAAR δ subunit is selectively removed from CRH neurons (Gabrd/Crh mice), resulting in a loss of tonic GABAergic inhibition in these neurons. Interestingly, the loss of this tonic GABAergic constraint did not significantly alter basal levels of corticosterone (CORT). However, the loss of the GABAAR δ subunit in CRH neurons blunted the CORT response to stress, likely due to the loss of the disinhibitory effect of GABA following acute stress. This blunting of HPA axis reactivity was associated with a decrease in depression-like and anxiety-like behaviors. Exogenous CORT was sufficient to increase anxiety-like and depression-like behaviors in Gabrd/Crh mice. Together, these results show the importance of the GABAAR δ subunit in the regulation of CRH neurons, and thus the HPA axis, and demonstrate that dysregulation of CRH neurons alters stress-related behaviors."xsd:string |
