Alzheimer's disease is a neurodegenerative condition characterized by an accumulation of toxic amyloid beta- (A-)peptides in the brain causing progressive neuronal death. A-peptides are produced by aspartyl proteinase-mediated cleavage of the larger amyloid precursor protein (APP). In contrast to this detrimental “amyloidogenic” form of proteolysis, a range of zinc metalloproteinases can process APP via an alternative “nonamyloidogenic” pathway in which the protein is cleaved within its A region thereby precluding the formation of intact A-peptides. In addition, other members of the zinc metalloproteinase family can degrade preformed A-peptides. As such, the zinc metalloproteinases, collectively, are key to downregulating A generation and enhancing its degradation. It is the role of zinc metalloproteinases in this “positive side of proteolysis in Alzheimer's disease” that is discussed in the current paper.
