neurofibrillary tangle

[‚nu̇·rō‚fīb·rə‚ler·ē ′taŋ·gəl]
(pathology)
The accumulation of twisted protein filaments (neurofibrils) within neurons of the cerebral cortex; a characteristic pathological feature found in the brains of Alzheimer's disease patients.

The combination of A[beta] oligomers, A[beta] plaques, P tau, and neurofibrillary tangles is thought to interfere with normal neural function in the brain, leading to synaptic dysfunction, impaired neuronal metabolism, and neuronal death (Ballard, 2011; Bekris et al.
PKC Isozymes Regulate Amyloid Plaque and Neurofibrillary Tangle Metabolism
The biogenesis of neurofibrillary tangles remains an important question in understanding AD, but an important consideration is that NFTs are associated with a number of diseases such as dementia pugilistica while other causes remain unclear.
Neurofibrillary tangles form in the transport system of nerve cells (neurons).
Neurofibrillary tangles (Figure 3, C) were present in the hippocampus and neocortex in the 2 oldest DS patients (ages 51 and 56 years) and in the hippocampus and entorhinal cortex of the same 23-year-old patient who showed neuritic plaques.
For decades now, scientists have known about two lesions that are characteristic of Alzheimer's disease - amyloid plaques and neurofibrillary tangles - that are found in the brains of all affected individuals.
The neuropathological features of AD are the presence of extracellular amyloid plaques and intracellular neurofibrillary tangles in the hippocampus and cortical grey matter of the AD brain.
2]N-8E12 is a humanized antibody targeting the tau protein found in neurofibrillary tangles in the brain of patients with tauopathies such as PSP and Alzheimer's disease (AD).
a) Therapeutic activity of curcuminoids in AD may target amyloid precursor protein and Ap activity, decrease in neurofibrillary tangles and improved cognition via attenuation of muscarinic insufficiency
Prof Lawrence Rajendran from the University of Zurich, Switzerland, who elaborated on the cellular complexities underlying Alzheimer s Disease, in his plenary lecture, said that the disease presents itself with two distinguishing features in terms of its pathogenesis, one formation of neurofibrillary tangles and the other, amyloid plaques.
The focus on a downstream target to treat Alzheimer's, rather than on amyloid beta plaques and neurofibrillary tangles -- approaches which have shown little success -- "is very exciting because everyone is now looking for an earlier treatment of the disease," Lipton said.
Several experimental studies suggest that some anaesthetics could promote inflammation of neural tissues leading to POCD and/or Alzheimer's disease (AD) precursors including beta-amyloid plaques and neurofibrillary tangles.
