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. WebApr 2, 2024 · During this maturation process, neurofibrillary tangles (NFTs) form inside the affected neuron resulting in axonal instability that impairs transport of nutrients and cell signal communication. Advances in PET imaging allow for the detection of abnormal tau accumulation in the living brain. fnb ortopedie
