" Senile plaques (SP) and neurofibrillary tangles (NFT) are the major histopathological changes that occur in Alzheimer's disease (AD). How these two different types of lesions are related to each other and to the dementia of AD is unknown. Recent studies lead to paradoxical conclusions: NFT and neuronal alterations such as synapse loss are much more closely related to the symptoms of dementia than are SP. However, mutations in the beta-amyloid protein of SP have been found in some patients with familial AD, suggesting that an abnormality in amyloid causes the development of SP, NFT and AD dementia. Examination of transgenic animals that produce amyloid precursor protein (APP), or altered forms of APP, may lead to the development of an animal model of AD, and ultimately to answers that link amyloid production to neuronal alterations, and cognitive impairments."
APBA1:
"The protein encoded by this gene is a member of the X11 protein family. It is a neuronal adapter protein that interacts with the Alzheimer's disease amyloid precursor protein (APP). It stabilizes APP and inhibits production of proteolytic APP fragments including the A beta peptide that is deposited in the brains of Alzheimer's disease patients. This gene product is believed to be involved in signal transduction processes. It is also regarded as a putative vesicular trafficking protein in the brain that can form a complex with the potential to couple synaptic vesicle exocytosis to neuronal cell adhesion.
