Aβ peptides are generated in neuronal secretory vesicles by proteolytic cleavage of the amyloid precursor protein (APP) by proteases, called β-secretase and γ-secretase that cleave at the N-terminus and variant C-termini of Aβ within APP, respectively, resulting in Aβ of 40 or 42 amino acids (Aβ40 and Aβ42, respectively) (Figure 1). Because the N-termini of Aβ40 and Aβ42 are identical, development of inhibitors that reduce cleavage of APP at the β-secretase site are likely to be effective for reducing Aβ peptide forms with alleviation of neurodegeneration and memory deficit. The APP in the vast majority of AD patients possesses the wild-type β-secretase site sequence. <ref>14</ref> | Aβ peptides are generated in neuronal secretory vesicles by proteolytic cleavage of the amyloid precursor protein (APP) by proteases, called β-secretase and γ-secretase that cleave at the N-terminus and variant C-termini of Aβ within APP, respectively, resulting in Aβ of 40 or 42 amino acids (Aβ40 and Aβ42, respectively) (Figure 1).
