WebAmyloid-β peptides are proteolytic fragments of the transmembrane amyloid precursor protein, whereas tau is a brain-specific, axon-enriched microtubule-associated protein. The behavioral symptoms of AD correlate with the accumulation of plaques and tangles, and they are a direct consequence of the damage and destruction of synapses that ... WebApr 19, 2024 · Tau tangles are more strongly associated with Alzheimer’s symptom severity, even if they are thought to form only after amyloid plaques. Some brain imaging studies suggest that tau tangles, as opposed to amyloid plaques, drive disease progression. Another study suggests that there are distinct trajectories of tau tangles in the brain.

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. WebToxic Aβ species stimulate formation of pathological tau by modulating protein kinases and phosphatases that regulate tau phosphorylation and by inducing tau misfolding. Toxic forms of tau mediate the synaptic dysfunction and neuron death that underlie memory and cognitive impairment in AD, so the signature adverse effects of Aβ require tau.
