Amyloid beta (Aβ or Abeta) denotes peptides of 36–43 amino acids that are the main component of the amyloid plaques found in the brains of people with Alzheimer's disease. The peptides derive from the amyloid-beta precursor protein (APP), which is cleaved by beta secretase and gamma secretase to yield Aβ in a … See more The normal function of Aβ is not well understood. Though some animal studies have shown that the absence of Aβ does not lead to any obvious loss of physiological function, several potential activities have been … See more Aβ is formed after sequential cleavage of the amyloid precursor protein (APP), a transmembrane glycoprotein of undetermined function. APP can be cleaved by the See more Amyloid beta is commonly thought to be intrinsically unstructured, meaning that in solution it does not acquire a unique tertiary fold but rather populates a set of structures. As such, … See more Imaging compounds, notably Pittsburgh compound B, (6-OH-BTA-1, a thioflavin), can selectively bind to amyloid beta in vitro and in vivo. This technique, combined with PET imaging, is used to image areas of plaque deposits in those with Alzheimer's. Post mortem or in … See more Aβ is the main component of amyloid plaques, extracellular deposits found in the brains of people with Alzheimer's disease. Aβ can also form the deposits that line See more Autosomal-dominant mutations in APP cause hereditary early-onset Alzheimer's disease (familial AD, fAD). This form of AD accounts for no more than 10% of all cases, and the vast majority of AD is not accompanied by such mutations. However, familial … See more Researchers in Alzheimer's disease have identified several strategies as possible interventions against amyloid: • β-Secretase inhibitors. These work to block the first cleavage of APP inside of the cell, at the endoplasmic reticulum. • γ-Secretase inhibitors … See more WebTranslations in context of "bêta-amyloïdes" in French-English from Reverso Context: Les zones rouges sont des agrégats de bêta-amyloïdes.

WebBackground: The amyloid beta (Abeta) peptide is a key molecule in the pathogenesis of Alzheimer's disease. Reliable methods to detect and quantify soluble forms of this peptide in human biological fluids and in model systems, such as cell cultures and transgenic animals, are of great importance for further understanding the disease mechanisms.
