Brain-derived neurotrophic factor (BDNF) exon VI promoter is implicated in mediating activity-induced synthesis of hippocampal BDNF. BDNF is implicated in (R,S)-ketamine's antidepressant effects, but its role in (R,S)-ketamine-mediated prophylaxis is unknown. Using BDNF-e6 mice, in which promoter VI-driven BDNF production is disrupted, we tested its necessity for (R,S)-ketamine's prophylactic...
There has been a recent renewal of interest in the therapeutic potential of serotonergic psychedelics. Here, we uncover the essential role of ventral hippocampus (vHpc) GABAergic interneurons in the anxiolytic effect evoked by the serotonergic psychedelic 2,5-dimethoxy-4-iodoamphetamine (DOI). Integrating anatomical, pharmacological, and genetic approaches, we show that 5-HT2A receptors in the...

Childhood trauma and neglect influence emotional development and increase the risk for and severity of mental illness. Women have a heightened susceptibility to the effects of early life stress (ELS) and are twice as likely as men to develop debilitating, stress-associated disorders later in life, such as major depressive disorder (MDD). Until now, mouse models of depression have been largely...
