Comparing 2 hypotheses side-by-side
Galectin-3 (LGALS3) is an emerging opsonin that bridges damaged membranes to C1q. During prolonged anesthesia, oxidative stress and mitochondrial dysfunction cause specific synaptic populations to externalize phosphatidylserine (PS) and accumulate AGEs on synaptic proteins. Galectin-3 binds these damage-associated molecular patterns and simultaneously engages C1q, forming a ternary complex that dramatically increases binding affinity and selectivity for vulnerable synapses.
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
