Senile plaque neurites in Alzheimer disease accumulate amyloid precursor protein.
Senile plaques are polymorphous beta-amyloid protein deposits found in the brain in Alzheimer disease and normal aging. This beta-amyloid protein is derived from a larger precursor molecule of which neurons are the principal producers in brain. We found that amyloid precursor protein (APP)-immunoreactive neurites were involved in senile plaques and that only a subset of these neurites showed ma...
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 کاملIs there a spatial association between senile plaques and neurofibrillary tangles in Alzheimer's disease?
OBJECTIVE To test the hypothesis that the clusters of senile plaques (SP) and neurofibrillary tangles (NFT) in patients with Alzheimer's disease (AD) are spatially associated as predicted by the 'Amyloid Cascade Hypothesis'. METHODS The spatial association between the SP and NFT was studied in the cerebral cortex and hippocampus in six cases of sporadic Alzheimer's disease (AD) using continge...
متن کاملSenile plaques and neurofibrillary tangles in cortical neurons in AD
Neurodegenerative disorders are characterized clinically by insidious onset and slowly progressive course, and are frequently hereditary. Pathologically, these diseases share a common feature: the selective loss of a particular subset of neurons for unknown reasons [e.g. cerebral cortical neurons in ALZHEIMER’S DISEASE (AD) (see Glossary), substantia nigra neurons in PARKINSON’S DISEASE (PD), s...
