Comparing 2 hypotheses side-by-side
Under physiological conditions, microglia maintain non-overlapping territorial domains regulated by P2Y12 purinergic receptors sensing extracellular ATP/ADP gradients from active synapses. Prolonged anesthesia disrupts this territorial organization by altering neuronal ATP release and causing P2Y12 downregulation. Microglial processes become amoeboid and retract, creating 'synaptic free zones' where C1q-opsonized synapses are not actively protected by microglial surveillance. Synapses near retai
Excitatory synapses on specific neuronal compartments (distal dendrites of CA1 pyramidal neurons) express low levels of membrane complement regulators CD46 and CD55, while inhibitory synapses and synapses on interneurons express high levels. During anesthesia, C1q binds preferentially to synapses lacking these regulators. Local C3a generation serves as a potent 'find-me' signal to recruiting microglia specifically to these unprotected synapses. Peptidomimetic enhancement of complement regulation
