Early life experience modulates resilience to stress in later life. Previous research implicated maternal care as a key mediator of behavioral responses the adversity adolescence, but details molecular mechanisms remain elusive. Here, we show social activates transcription factor C/EBPβ mPFC neurons adolescent mice, which transcriptionally upregulates Dnm1l and promotes mitochondrial dysfunction, thereby conferring susceptibility mice. Moreover, different separation differentially regulates susceptibility. Mechanistically, this differential effect depends on behavior-stimulated IGF-1, inhibits neuronal through mTORC1-induced C/EBPβ-LIP translation. Furthermore, identify IGF-1 is mainly released from microglia. Notably, increased under an environmental enrichment condition or behavior impairment induced by repeated MPOAEsr1+ cells inhibition dams prevents via microglial-to-neuronal IGF-1-C/EBPβ-DRP1 signaling. In work, these findings have unveiled adolescents. Here authors that triggers microglia-derived levels, suppresses C/EBPβ-DRP1 axis, promoting
