Abstract

AbstractStress resilience is the ability of neuronal networks to maintain function despite exposure to stress. In this study, we investigated whether stress resilience is an actively developed dynamic process in adult mice. To assess the resilient and anhedonic behavioral phenotypes developed after induction the chronic unpredictable stress, we quantitatively characterized the structural and functional plasticity of excitatory synapses in the hippocampus using a combination of proteomic, electrophysiological, and imaging methods. Our results indicate that stress resilience is a dynamic and multifactorial process manifested by structural, functional, and molecular changes in synapses. We reveal that chronic stress influences palmitoylation, the profiles of which differ between resilient and anhedonic animals. We also observed that stress resilience is associated with structural compensatory plasticity of the postsynaptic parts of synapses.One Sentence SummaryCompensatory remodeling of dendritic spines at the structural and molecular levels underlies stress resilience.
