Perineuronal Net Depolymerization as Early Synaptic Vulnerability Trigger
🧪 Overview
CSPG degradation of perineuronal nets precedes synaptic loss in prodromal neurodegeneration. Early increases in MMP activity initiate PNN loss around parvalbumin+ inhibitory interneurons. PNN removal exposes synaptic sites to oxidative stress and dysregulates calcium buffering, accelerating excitatory synapse loss and creating network hyperexcitability.
