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.
Direct evidence of phosphorylated neuronal intermediate filament ...
2011年3月28日 · Here, we provide direct evidence on the identity of NFs in NFTs by immunochemical and mass spectrometric analysis. We have purified sarkosyl-insoluble NFTs and performed liquid chromatography/tandem mass spectrometry of NFT tryptic digests.

Physiology and pathology of tau protein kinases in relation to ...
The main component of NFT is paired helical filaments (PHF), which mainly consist of hyperphosphorylated tau protein. Tau protein kinases I and II were found as candidate enzymes responsible for hyperphosphorylation of tau to induce the formation of PHF.

2020年2月25日 · Neurofibrillary tangle (NFT), bundle of paired helical filaments in neurons is one of the defining features of Alzheimer’s disease (AD) and their spreads well correlate with disease symptoms and progression of AD. Using the unusual insolubility, NFTs were partially purified and the antibodies were produced.
