**Molecular Mechanism and Rationale**
The molecular mechanism underlying MHC class I-mediated synaptic vulnerability centers on the intersection of neuronal stress responses and microglial complement-dependent phagocytosis. Under metabolic stress conditions, particularly during anesthesia-induced hypoxia or energy depletion, specific neuronal populations including CA1 pyramidal neurons and layer 2/3 prefrontal cortical neurons activate the unfolded protein response (UPR) and endoplasmic reticul
The activity-dependent trafficking of complement regulators CD55 and CD46 to synaptic surfaces represents a dynamic regulatory mechanism controlling complement-mediated synaptic pruning through vesicular transport and membrane insertion. Rather than static differential expression, CD55 and CD46 undergo rapid, activity-dependent translocation from intracellular vesicular pools to synaptic membranes via SNARE-mediated exocytosis. High-frequency synaptic activity triggers calcium influx through NMD
