Amyloid β Peptides

Amyloid β (Aβ) peptides are the major component of amyloid plaques found in the brains of Alzheimer's patients. Aβ is formed from the progressive cleavage of amyloid precursor protein (APP) by β- and γ-secretase. Two Aβ peptides are formed from APP degradation.

    Amyloid β (Aβ) peptides are the major component of amyloid plaques found in the brains of Alzheimer's patients. Aβ is formed from the progressive cleavage of amyloid precursor protein (APP) by β- and γ-secretase. Two Aβ peptides are formed from APP degradation; Aβ40 and Aβ42. Aβ40 is the most abundant form, but Aβ42 is more fibrillogenic, thus is associated with disease states.

    Mutations in APP have been linked to early onset Alzheimer's disease, as proteolytic cleavage of the altered protein increases the levels of Aβ42 relative to Aβ40. Furthermore, Aβ proteins have been associated with other diseases including Lewy body dementia, inclusion body myositis and cerebral amyloid angiopathy.
