Evidence for (5)
Glymphatic impairment directly reduces tau clearance in AD mouse models, with AQP4 polarization loss as the primary mechanism — foundational evidence for the hypothesis.
Glymphatic and meningeal lymphatic dysfunction are core features of AD pathophysiology, reducing both amyloid-beta and tau clearance and representing a disease-modifying therapeutic target.
Removal of astrocytic PERK restores glymphatic function and reduces pathological tau aggregate clearance failure, linking ER stress to glymphatic tau accumulation.
Glymphatic pathway impairment promotes tau pathology accumulation after TBI — establishes the causal link between glymphatic failure and tau spreading.
Sleep-dependent glymphatic clearance of tau and amyloid is impaired in AD, with proteomics data identifying specific transport proteins dysregulated in glymphatic failure.
