What This Experiment Tests

Validation experiment designed to validate causal mechanisms targeting HOMER1A,GRIA1,GRIA2,GRIA3,GRIA4 in C57BL/6J mice with stress-induced depression. Primary outcome: Sleep architecture parameters and glutamatergic plasticity markers

Description

This experiment examined sleep regulation and homeostatic glutamatergic plasticity in the medial prefrontal cortex (mPFC) of mice with stress-induced depression-like phenotype. The study characterized altered sleep architecture, impaired sleep homeostasis, and disrupted day-night oscillations of glutamatergic plasticity markers including Homer1a and synaptic AMPAR expression. The mice showed blunted response to sleep deprivation with impaired rebound slow-wave activity, attenuated recovery sleep, and altered upregulation of Homer1a and AMPAR compared to controls.
