Significance Chronic stress alters the hippocampal responses to familiar and novel stressors, behaviorally, physiologically, and epigenetically. In the aftermath of chronic stress in WT mice and in mice with a BDNF loss-of-function allele without any applied stress, there is a window of plasticity that allows familiar and novel experiences to alter anxiety- and depressive-like behaviors, reflected also in electrophysiological changes in the dentate gyrus (DG) in vitro. A consistent biomarker of mood-related behaviors in DG is reduced type 2 metabotropic glutamate (mGlu2), which regulates the release of glutamate. Within this window, familiar stress rapidly and epigenetically up-regulates mGlu2 by a P300-driven histone H3 lysine 27 acetylation and improves mood behaviors. This transient epigenetic plasticity may be useful for treatment of stress-related disorders where dysregulaton of glutamate is involved.
