Cleavage of amyloid precursor protein (APP). Aβ-peptides, which are sequentially released from the amyloid precursor protein (APP) by β- and γ-secretase, are responsible for amyloid plaques. In addition, α-secretase and γ-secretase can sequentially cleave APP, yielding non-amyloidogenic fragments. Since APP and β-secretase are primarily expressed in neurons, most Aβ is produced in neurons
