From: Maternal behavior promotes resilience to adolescent stress in mice through a microglia-neuron axis

In the mPFC of adolescent mice with low maternal care, social stress activates transcription factor C/EBPβ in mPFC neurons, upregulating Dnm1l expression and promoting mitochondrial dysfunction, which confers to stress susceptible in adolescent mice. However, high maternal care stimulates microglia to relieve IGF-1, which inhibit neuronal C/EBPβ activity through mTOR-induced C/EBPβ-LIP translation via binding to IGF-1R on the neurons in the mPFC of offspring, which protects stress resilience in adolescence.
