The molecular and cellular processes that lead to the production of the amyloid beta (A beta) peptide and some of the processes associated with A beta fibrillogenesis and neurotoxicity have recently been elucidated. Experimental results have suggested that abnormalities in the processing of the beta-amyloid precursor protein (beta APP) are central to the pathogenesis of Alzheimer's disease (AD). beta APP processing includes two mutually exclusive proteolytic cleavage pathways, one involving the putative gamma-secretase enzyme, the identity of which remains unknown. Recent evidence has suggested the presenilin 1 and presenilin 2 genes are necessary for gamma-secretase activities. Another gene associated with susceptibility to AD is the apolipoprotein E (APOE) gene. Given the important role that abnormal processing of beta APP plays in the genesis of AD, most current efforts are directed at either modulating A beta peptide production or inhibiting its ability to aggregate into fibrils and cause neurotoxicity. To inhibit A beta production, one strategy might be to inhibit either beta-secretase or gamma-secretase. Several approaches to the inhibition of A beta aggregation are under investigation.
