Human Amyloidosis and In Vitro Formation of Alzheimer Amyloid Fibrils,e proteins share the properties of a β-pleated sheet secondary structure, insolubility, green birefringence after Congo red staining and the formation of fibrils with a typical electron microscopic appearance.. The deposition of amyloid fibrils is the resultant of a diversity of pathological conditi

Cloning of Neurofibrillary Tangle-Related Genes,ary tangles (NFT). Electron microscopists were among the first to observe the relative paucity of microtubules in NFT-containing neurons. The microtubular system was later implicated immunochemically, based on an antiserum that cross-reacted with NFT and microtubules.. In 1980 Eng et al.. demonstrat

The theory is based on determination of the intensity of tangle formation and plaque counts carried out at the light microscope level, on one hand, and measures of dementia, on the other. Twenty years have passed since this theory was formulated. During t

Alteration of the Neurofilament-Microtubule Network in Alzheimer Disease and Other NeurodegenerativNFT and SP have been found to correlate with the severity of the dementia (1–3). NFT are primarily composed of paired helical filaments (PHF), although 15 nm straight filaments and amorphous components are also common constituents (4). SP, or neuritic plaques, are composed of a core of cerebral amyl

Immunochemical Studies of the Relationship Between the Neuronal Cytoskeleton and Neurofibrillary Tatangles in the cerebral cortex has a diagnostic significance in that the frequency of these structures and the extent of choline acetyltransferase loss is correlated with the degree of dementia .. Tangles are large accumulations of fibrous proteins, the bulk of which has been shown to be composed of
