Neurofibrillary tangle - Wikipedia

WebOct 19, 2024 · Tau pathology accumulates intracellularly, as hyperphosphorylated tau fibrillates into the paired helical filaments that form neurofibrillary tangles, ultimately killing the neuron. In contrast, Aβps accumulate extracellularly from the aggregation and fibrillation of Aβ peptides that are released from neurons into the extracellular space. Neurofibrillary tangles (NFTs) are aggregates of hyperphosphorylated tau protein that are most commonly known as a primary biomarker of Alzheimer's disease. Their presence is also found in numerous other diseases known as tauopathies. Little is known about their exact relationship to the different pathologies. crypto post.at
