Can microglial polarization states selectively target excitatory vs inhibitory synapses during complement-mediated elimination?

OPEN

The hypothesis that M1-like microglia eliminate excitatory synapses (cognition) while M2-like target inhibitory synapses (anxiety) was proposed but remains untested. This synapse-type selectivity could explain dual behavioral phenotypes.
