Astrocytes express multiple phagocytic receptors including MEGF10 (multiple EGF-like domains 10) that enable direct synaptic material engulfment independent of microglial activation. This hypothesis proposes that targeted upregulation of astrocytic MEGF10 expression can provide more precise temporal and spatial control over synaptic pruning compared to microglial TREM2 activation. MEGF10 functions through recognition of phosphatidylserine exposure on synaptic terminals marked for elimination, tr
This hypothesis proposes that microglial TREM2 activation serves as a master regulator that coordinates both synaptic pruning and oligodendrocyte precursor cell (OPC) maturation to restore structural connectome integrity. TREM2-activated microglia would function as central orchestrators, using their synaptic pruning machinery to identify damaged or dysfunctional neural circuits while simultaneously releasing specific trophic factors and cytokines that promote OPC differentiation into mature olig
