The Non-Amyloidogenic Pathway: Structure and Function of α-Secretases
2006
The amyloid cascade hypothesis is the most accepted explanation for the pathogenesis of Alzheimer’s disease (AD). APP is the precursor of the amyloid β peptide (Aβ), the principal proteinaceous component of amyloid plaques in brains of Alzheimer’s disease patients. Proteolytic cleavage of APP by the α-secretase within the Aβ sequence precludes formation of amyloidogenic peptides and leads to a release of soluble APPsα which has neuroprotective properties. In several studies, a decreased amount of APPsα in the cerebrospinal fluid of AD patients has been observed. Three members of the ADAM family (a disintegrin and metalloproteinase) ADAM-10, ADAM-17 (TACE) and ADAM-9 have been proposed as α-…
