Because inhibition of DG GCs is necessary for the response to antidepressant treatment, we assessed whether direct inhibition of GCs in the ventral DG mimicked antidepressant treatment. We show that Gi-DREADD-mediated inhibition of the ventral DG results in a decrease in negative valence behaviors, like what is seen after chronic antidepressant treatment. We also assessed whether direct inhibition or stimulation of GCs in the ventral DG could alter response to antidepressant treatment. We show that Gi-DREADD-mediated inhibition of the ventral DG results in the conversion of non-responders to fluoxetine (an antidepressant; FLX) treatment into responders, while Gq-DREADD-mediated stimulation results in conversion the of responders to FLX treatment into non-responders. Taken together, these data suggest that inhibition in the ventral DG is necessary for the antidepressant response and illustrate that it is possible to bidirectionally alter the behavioral response to FLX treatment.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Listen to the audio presentation Title:\u00a0 The Effect of Chemogenetic DREADD Manipulation in the Ventral Dentate Gyrus of Chronically Stressed Females on the Behavioral Antidepressant Response Name:\u00a0Allyson Barzer Major: \u00a0Psychology &hellip; <a href=\"https:\/\/sites.rutgers.edu\/nb-senior-exhibits\/partners\/aresty-research-virtual-symposium-2020\/bazer-allyson-the-effect-of-chemogenetic-dreadd-manipulation-in-the-ventral-dentate-gyrus-of-chronically-stressed-females-on-the-behavioral-antidepressant-response\/\" class=\"\">Read More<\/a><\/p>\n","protected":false},"author":970,"featured_media":0,"parent":441,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"template-custom.php","meta":{"_acf_changed":false,"footnotes":""},"class_list":["post-853","page","type-page","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v23.5 -
