Tangles of tau
Did you know?
The traditional understanding is that tau binds to microtubules and assists with their self-assembly, formation and stabilization. However, when tau is hyperphosphorylated, it is unable to bind and the microtubules become unstable and begin disintegrating. The unbound tau clumps together in formations called neurofibrillary tangles. More explicitly, intracellular lesions known as pretangle… WebNov 7, 2024 · A new study, led by investigators in NIA's Intramural Research Program, suggests that the presence of tau tangles might be associated with cognitive change early in the Alzheimer’s disease process. Results were reported in September in Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring.
WebFeb 16, 2024 · Researchers have discovered how a molecule found in green tea breaks apart tangles of the protein tau, a hallmark of Alzheimer’s disease. Based on this finding, the team identified other molecules that can also untangle tau and may be better drug candidates than the green tea molecule.
WebAlzheimer’s disease (AD) is a neurodegenerative disorder characterized by a progressive memory loss and cognitive decline that has been associated with an accumulation in the brain of intracellular neurofibrillary tangles (NFTs) formed by hyperphosphorylated tau protein, and extracellular senile plaques formed by β-amyloid peptides. WebIn Alzheimer's disease brain, tau is abnormally hyperphosphorylated to a stoichiometry of at least three-fold greater than normal tau, and in this altered state it is aggregated into paired helical filaments forming neurofibrillary tangles, a histopathological hallmark of the disease.
