Comparing 2 hypotheses side-by-side
The microglial-mediated tau clearance dysfunction hypothesis focuses on the disruption of TREM2-dependent phagocytic clearance of extracellular tau aggregates by activated microglia. Under normal conditions, TREM2 (triggering receptor expressed on myeloid cells 2) recognizes phosphatidylserine and other damage-associated molecular patterns on tau-containing extracellular vesicles and neuronal debris, initiating PI3K/AKT signaling cascades that promote microglial survival, proliferation, and enha
## Molecular Mechanism and Rationale The glymphatic-mediated tau clearance dysfunction hypothesis centers on the disruption of cerebrospinal fluid-interstitial fluid exchange through impaired aquaporin-4 (AQP4) water channel function at astrocytic endfeet. Under normal conditions, polarized AQP4 distribution facilitates bulk flow clearance of soluble tau and other metabolic waste products through perivascular spaces. However, hyperphosphorylated tau species, particularly those phosphorylated at
