Phosphatidylinositol-4,5-bisphosphate is enriched in granulovacuolar degeneration bodies and neurofibrillary tangles
AIMS Among the pathological findings in Alzheimer's disease (AD), the temporal and spatial profiles of granulovacuolar degeneration (GVD) bodies are characteristic in that they seem to be related to those of neurofibrillary tangles (NFTs), suggesting a common mechanism underlying the pathogenesis of these structures. Flotillin-1, a marker of lipid rafts, accumulates in lysosomes of tangle-beari...
متن کاملCyclin-dependent kinase 5 immunoreactivity for granulovacuolar degeneration.
In addition to senile plaque and neurofibrillary tangles, granulovacuolar degeneration is a hallmark of Alzheimer's disease. A number of tau kinases, such as c-jun N-terminal kinase (JNK), glycogen-synthase kinase-3β (GSK3β), and casein kinase 1 (CK1), have been reported to be markers of granulovacuolar degeneration. In addition, cyclin-dependent kinase 5 (CDK5), which phosphorylates tau, has b...
متن کاملNeurofibrillary Tangles of Aβx-40 in Alzheimer's Disease Brains.
The two pathognomonic lesions in the brain of AD patients are senile plaques and intraneuronal neurofibrillary tangles (NFT). Previous studies have demonstrated that amyloid-β (Aβ) is a component of both senile plaques and NFTs, and have showed that intracellular accumulation of Aβ is toxic for cells and precedes the appearance of extracellular amyloid deposits. Here we report that there are nu...
متن کاملNeurofibrillary tangles in nondemented elderly subjects and mild Alzheimer disease.
BACKGROUND The relationship between neuropathological lesions and mild, "preclinical," cognitive impairments of Alzheimer disease is poorly understood. Identification of the lesions that are most closely associated with the earliest symptoms of Alzheimer disease is crucial to the understanding of the disease process and the development of treatment strategies to affect its progression. DESIGN...
متن کاملPhosphorylated neurofilament antigens in neurofibrillary tangles in Alzheimer's disease.
Neurofibrillary tangles (NFT) are a hallmark of Alzheimer's disease (AD), and their presence correlates with the presence of dementia. A major constituent of NFT is the insoluble paired helical filament which shares some antigenic relationships with normal cytoskeletal elements, particularly neurofilaments. If neurofilament proteins (200, 145-160, and 68 kilodaltons [kd]) participate in the for...
