Microglial GPR56 in synaptic pruning: mechanisms, comparative receptor biology, and context-dependent roles in brain disorders.
Microglia regulate synaptic remodelling, eliminating weakened and dysfunctional synapses to maintain circuit development and homeostasis. Adhesion G protein-coupled receptor G1 (ADGRG1/GPR56) has emerged as a distinctive regulator integrating phosphatidylserine recognition, mechano-transduction, and G-protein signallin...
