Webpeptides are generated from amyloid precursor protein as a result of sequential b-secretase and g-secretase proteolytic activity (De Strooper et al.,1998 ;Vassar 1999 Wolfe et al., 1999). Imprecise cleavage specificity by g-secretase results in the generation of a range of Ab peptides varying in C-terminal length from 37 up to 46 amino acids ... WebSeveral neurodegenerative diseases are correlated with amyloid fibrillar deposits ().For a number of these diseases, it has been postulated that amyloid fibers may not play the primary causative role ().Rather, soluble aggregates of the amyloidogenic proteins are likely the relevant etiological agents (2, 3).The most prevalent of these neurodegenerative …
