WebOct 23, 2013 · Accumulation and aggregation of the microtubule-associated protein tau are a pathological hallmark of neurodegenerative disorders such as Alzheimer’s disease (AD). In AD, tau becomes abnormally phosphorylated and forms inclusions throughout the brain, starting in the entorhinal cortex and progressively affecting additional brain regions as the …
WebMay 2, 2024 · The findings may lead to strategies that could help detect the condition early. For years, researchers have known that amyloid-β and tau pathologies, the hallmarks of Alzheimer’s disease, can cause the death of neurons — the brain’s most abundant cells — which eventually leads to impairment and dementia. “But we did not know how the ... WebMay 24, 2016 · The brain scans revealed markedly increased tau levels in the brains of people with early Alzheimer’s disease compared to healthy participants. Those differences were particularly notable in the temporal lobe, a portion of the brain known to play a role in memory, and in the cerebral cortex. The researchers also observed increases in beta ...
Web2 days ago · The role of metals in the pathogenesis of Alzheimer’s disease (AD) is still debated.
