Tau hypothesis
WebJan 30, 2024 · Alzheimer’s disease (AD) is a progressive neurodegenerative disorder and the most common cause for dementia. There are many hypotheses about AD, including abnormal deposit of amyloid β (Aβ) protein in the extracellular spaces of neurons, formation of twisted fibers of tau proteins inside neurons, cholinergic neuron damage, inflammation, … WebSep 2, 2024 · Research in Alzheimer’s disease has recently been plagued by intense disappointment. For over 25 years, the majority of scientists pursued the so-called amyloid-beta hypothesis — the initially compelling idea that the key driver behind the disease is the accumulation of plaques of the amyloid-beta protein in the brain.

Web1.04.2.1.3. Tau hypothesis supports tau as an AD biomarker NFTs are fibrillar aggregates constituted mainly by PHFs of the abnormal hyperphosphorylated form of tau protein. Tau is a neuronal microtubule-associated protein, which is involved in microtubule stabilization, and plays an important physiological role in microtubule dynamics and axonal transport.
