Definitions for "Amyloid plaque"
a plaque consisting of tangles of amyloid protein in nervous tissue (a pathological mark of Alzheimer's disease)
a build up of beta-amyloid protein. Amyloid plaques are one of the characteristic structural abnormalities found in the brains of Alzheimer patients. Upon autopsy, the presence of amyloid plaques and neurofibrillary tangles is used to positively diagnose Alzheimer's disease.
amyloid proteins involved in Alzheimer's Disease and other diseases of amyloidosis aggregate into insoluble fibrils that are deposited in amyloid plaques in the brains of Alzheimer's patients.
