How do neurofibrillary tangles form
WebThe pathology of Alzheimer’s disease involves two types of protein aggregates: intracellular occlusions, termed neurofibrillary tangles, composed of hyperphosphorylated tau protein or neuritic plaques which are extracellular aggregates of Aβ peptide, a product of amyloid precursor protein ( Ross & Poirier, 2004 ). WebNeurofibrillary tangles (NFTs) are a fundamental neuropathological hallmark of AD. NFT-bearing neurons have been characterised by loss of cytoskeletal microtubules and …
