Aducanumab, sold under the brand name Aduhelm, is a monoclonal antibody designed to treat Alzheimer's disease. It is a monoclonal antibody that targets aggregated forms (plaque) of amyloid beta (Aβ) found in the brains of people with Alzheimer's disease to reduce its buildup. [10] It was developed by Biogen and Eisai. [11] Aducanumab is given via intravenous infusion. [5] Aducanumab was ...
Amyloid beta (Aβ) is composed of a family of peptides produced by proteolytic cleavage of the type I transmembrane spanning glycoprotein amyloid-beta precursor protein (APP). Amyloid plaque Aβ protein species ends in residue 40 or 42, [ 4 ] but it is suspected that Aβ42 form is crucial in the pathogenesis of AD.
Amyloid beta (Aβ, Abeta or beta-amyloid) 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. [2] The peptides derive from the amyloid-beta precursor protein (APP), which is cleaved by beta secretase and gamma secretase to yield Aβ in a cholesterol ...
p3 peptide also known as amyloid β- peptide (Aβ) 17–40/42 is the peptide resulting from the α-and γ-secretase cleavage from the amyloid precursor protein . It is known to be the major constituent of diffuse plaques observed in Alzheimer's disease (AD) brains and pre-amyloid plaques in people affected by Down syndrome. However, p3 peptide ...

A main theory behind the cause of Alzheimer’s disease is the build-up of the protein amyloid-beta in the brain. Researchers from the University of Cincinnati provide evidence suggesting it’s ...
From the age of 60 years (10%) to the age of 80 years (60%), the proportion of people with senile plaques increases linearly. Women are slightly more likely to have plaques than are men. [45] [44] Both plaques and Alzheimer's disease also are more common in aging persons with trisomy-21 (Down syndrome).
Cleavage by gamma secretase within the membrane-spanning domain after beta-secretase cleavage generates the amyloid-beta fragment; gamma secretase is a large multi-subunit complex whose components have not yet been fully characterized, but include presenilin, whose gene has been identified as a major genetic risk factor for Alzheimer's.
