True prions stably maintain unique conformations ("strains") in vivo that link structure to patterns of pathology. We now find that tau meets this criterion. WebApr 5, 2024 · In Alzheimer's disease, tau inclusions co-exist with extracellular plaques of amyloid-β, yet the severity of cognitive decline correlates with the burden of tau inclusions.1 In Alzheimer's disease and in other tauopathies, pathological tau appears to spread via a prion-like mechanism (referred to as seeded aggregation). take note another word
