Circuit-specific hippocampal ΔFosB underlies resilience to stress-induced social avoidance

Abstract

Chronic stress is a risk factor for mood disorders, yet the molecular and circuit mechanisms of stress-induced changes are not well understood. Here, the authors report the role of the transcription factor ΔFosB in driving activity changes in response to stress in glutamatergic neurons in the ventral hippocampus that project to nucleus accumben.
