Comparing 2 hypotheses side-by-side
Differential neural activity during anesthesia creates 'eat-me' vs. 'don't-eat-me' synaptic signatures through CREB-mediated BDNF signaling. Spared circuits maintain CREB activation and autocrine BDNF release, which upregulates neuronal complement inhibitors (CD46, CD55) and downregulates C1q-binding phosphatidylserine exposure. Synapses in suppressed circuits lack this protection and become targets. However, the assumption of circuit-specific sparing during prolonged sevoflurane/isoflurane anes
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
