Comparing 2 hypotheses side-by-side
This hypothesis proposes that TREM2-mediated microglial signaling serves as the master regulator of thalamocortical oscillatory networks that drive glymphatic tau clearance. The mechanistic framework centers on TREM2/DAP12 signaling in perivascular microglia directly modulating the function of extrasynaptic GluN2B receptors in thalamocortical circuits through microglial cytokine release and synaptic pruning. When TREM2 signaling is intact, microglia maintain optimal thalamocortical connectivity
**Background and Rationale** TREM2 variants represent major genetic risk factors for Alzheimer's disease, with loss-of-function mutations increasing dementia risk threefold. While TREM2 is exclusively expressed on microglia, emerging evidence suggests its primary pathogenic role occurs through disrupted astrocyte-microglia communication rather than intrinsic microglial dysfunction. Healthy brain homeostasis depends on coordinated responses between these glial populations, where TREM2+ microglia
