Neurofibrillary tangle - Wikipedia
Neurofibrillary tangles (NFTs) are intracellular 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.

Neurofibrillary Tangle - an overview | ScienceDirect Topics
Neurofibrillary tangles are neuronal inclusions composed largely of filamentous aggregates of hyperphosphorylated tau proteins that are variably ubiquitylated and glycated. In sections stained with hematoxylin and eosin, intracellular NFTs are faintly basophilic and extracellular NFTs appear eosinophilic (Fig. 31.16).
Neurofibrillary tangles and tau phosphorylation - PubMed
Neurofibrillary tangles (NFTs) are a characteristic neuropathological lesion of Alzheimer's disease (AD). They are composed of a highly-phosphorylated form of the microtubule-associated protein tau. We are investigating the relationship between …

2023年2月9日 · 淀粉样蛋白(aβ)斑块和高度磷酸化的神经原纤维缠结(nft)是阿尔茨海默病(ad)的两大主要病理表现。 Aβ斑块可以在痴呆发病前数年甚至数十年被检测到,说明其对认知正常人群的作用似乎不明显;相反地,NFT则与神经变性和认知损害有极大的关联。
Tau, tangles, and Alzheimer's disease - PubMed
2005年1月3日 · Neurofibrillary tangles (NFT) are comprised of the microtubule-associated protein tau, in the form of filamentous aggregates. In addition to the well-known changes in phosphorylation state, tau undergoes multiple truncations and shifts in conformation as it transforms from an unfolded monomer to the …
