  2. Amyloid plaques - Wikipedia

    en.wikipedia.org/wiki/Amyloid_plaques

    Two amyloid plaques from the brain of a patient with Alzheimer's disease. In this photomicrograph, neurites are darkly stained with the Naoumenko-Feigin silver method, and the pink elements (including the plaque cores) are stained with the periodic acid-Schiff (PAS) counterstain. The bar is 20 microns (0.02 mm) in length.

    en.wikipedia.org/wiki/Amyloid_beta

    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 ...

    The biochemistry of Alzheimer's disease, the most common cause of dementia, is not yet very well understood. Alzheimer's disease (AD) has been identified as a proteopathy: a protein misfolding disease due to the accumulation of abnormally folded amyloid beta (Aβ) protein in the brain. [1]
