摘要：
Aggregation of the beta-amyloid peptide (A beta) underlies the development of Alzheimer's disease. The review considers the main steps of the A beta formation and aggregation. Emphasis is placed on the interaction of zinc ions with the metal-binding domain 1-16 of A beta as a molecular mechanism leading to A beta aggregation. Recent studies of native modifications in the A beta metal-binding domain revealed its structural polymorphism. The prospects of further studying the modifications to determine the pathogenetic mechanism of A beta aggregation are discussed.
