However, this … WebOne of the major hallmarks of Alzheimer’s disease is the accumulation of the so-called “beta-amyloid plaques”. These plaques are formed when a type of protein in the brain, called amyloid precursor protein (APP), is broken down into smaller fragments. These fragments, which are called beta-amyloid, then clump together to form plaques.

WebProtein aggregation and subsequent accumulation of insoluble amyloid fibrils with cross-β structure is an intrinsic characteristic of amyloid diseases, i.e., amyloidoses. Amyloid formation involves a series of on-pathway and off-pathway protein aggregation events, leading to mature insoluble fibrils that eventually accumulate in multiple tissues. … WebAmyloid is a term used to characterize protein fragments that are produced by the body. When the brain is healthy and functioning correctly, these protein fragments are broken down and eliminated. But if the brain is not working as it should, these amyloid plaques clump together between nerve cells and can negatively affect brain function.
