Astrocytes play a critical role in synaptic pruning and maintenance of neural circuits through complement-mediated elimination of weak or aberrant synaptic connections. This hypothesis proposes that targeted activation of astrocytic complement cascade, specifically through C1q upregulation and subsequent C3 tagging of synapses, can restore optimal functional connectivity patterns in disrupted neural networks. Unlike structural remyelination approaches, this mechanism focuses on refining existing
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
