**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
This hypothesis proposes that the CREB-BDNF-TrkB activity-dependent signaling cascade directly controls the spatial positioning and expression levels of complement regulators CD55 and CD46 on synaptic membranes, creating an activity-based tagging system for synaptic elimination. High-frequency neural activity triggers calcium influx and CaMKIV/PKA-mediated CREB1 phosphorylation at serine 133, which transcriptionally upregulates CD55 and CD46 expression while simultaneously promoting their traffi
