This hypothesis proposes that astrocytic TREM2-like receptors (TREML2) regulate synaptic plasticity through a fundamentally different mechanism than microglial TREM2, focusing on synaptic strengthening rather than pruning. TREML2 expressed on astrocytic processes that contact synapses would detect damage-associated molecular patterns (DAMPs) and complement fragments deposited at weakened synapses. Upon activation, astrocytic TREML2 would trigger intracellular signaling cascades involving SYK kin
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
