Amyloid Beta: The Alternate Hypothesis
Current Alzheimer Research, 2006Alzheimer disease (AD) is a devastating condition and patients, caregivers, clinicians, and scientists are eager to decipher the underlying disease mechanism and, thereafter, target this therapeutically. Most investigators studying the underlying cause of AD have focused on amyloid-beta (Abeta) such that the Amyloid Cascade Hypothesis is the ...

Alzheimer's disease (AD), exhibiting accumulation of amyloid beta (Aβ) peptide as a foremost protagonist, is one of the top five causes of deaths. It is a neurodegenerative disorder (ND) that causes a progressive decline in memory and cognitive abilities. It is characterized by deposition of Aβ plaques and neurofibrillary tangles (NFTs) in the neurons,

Amyloid beta antagonizes insulin promoted secretion of the amyloid beta protein precursor
Journal of Alzheimer's Disease, 2002Amyloid β (Aβ) peptides are direct competitive inhibitors of insulin binding and action [25]. We demonstrate that Aβ peptides can inhibit the effect of insulin on the metabolic processing of the amyloid β protein precursor (AβPP). As evidence emerges concerning the role of insulin and insulin like growth factors (IGFs) in learning and memory, recent ...

Clinical outcomes of conversion to amyloid‐beta positivity in amyloid‐beta negative elderly
Alzheimer's & Dementia, 2023AbstractBackgroundEarly detection of amyloid beta (Aβ) accumulation has become important as Aβ accumulation begins before clinical symptoms appear. Previous longitudinal studies of Aβ‐negative (Aβ‐) people have shown that some of them convert to amyloid‐positive (Aβ+) and others remain amyloid‐negative.

Amyloid beta (A beta) is a 39-43 residue amyloidogenic peptide that is deposited into the extracellular amyloid plaques which characterize an Alzheimer's disease (AD) brain. A beta is derived from the amyloid precursor protein (APP) and undergoes a toxic conformational change (gain of toxic function).

Cholesterol, Lipids, Amyloid Beta, and Alzheimers
Current Alzheimer Research, 2010High levels of cholesterol have been proposed as a risk factor for Alzheimer's disease (AD). Polymorphism of genes encoding proteins that regulate cholesterol metabolism have also been associated with the frequency of Alzheimer's development. Some studies have shown that cholesterol-lowering drugs reduce the frequency of AD development.

Neuro-degenerative diseases, 2007
Alzheimer's disease (AD) is the most prevalent neurodegenerative disease in the growing population of elderly people. A hallmark of AD is the accumulation of plaques in the brain of AD patients. The plaques predominantly consist of aggregates of amyloid-beta (Abeta), a peptide of 39-42 amino acids generated in vivo by specific, proteolytic cleavage of ...
