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 cerebral blood vessels in cerebral amyloid angiopathy. The plaques are composed of a tangle of Aβ oligomers and regularly ordered aggregates called amyloid fibrils, a protein fold shared by other peptides such as the prions associated with protein misfolding diseases.
