This hypothesis proposes that activity-dependent CREB signaling creates spatially distinct complement vulnerability maps by differentially regulating CD55 and CD46 expression across synaptic populations. Low-activity synapses maintain high CREB1 phosphorylation through sustained calcium influx, driving transcription of CD55 and CD46 complement regulators via CRE-binding sites in their promoters. This creates complement-protected synaptic microenvironments where CD55 accelerates C3/C5 convertase
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
