Illustration：Contraryto β-amyloid peptides mutated at position 22 (Dutch, Italian, Arctic mutants)the Flemish mutation (A21G) shows a decreased tendency to aggregate and areduced neurotoxicity. In the studies of Betts and Tsubuki, A21G was degradedsignificantly more slowly by neprilysin than the wild-type Aβ (1-40) and theE22 mutants. The relative resistance to proteolytic degradation may account forthe pathogenicity of the Aβ mutant.
