mediated, at least in part, by beta-amyloid protein. A relationship between the aggregation
state of beta-amyloid protein and its ability to promote degeneration in vitro has been
previously suggested. To evaluate this hypothesis and to define a structure-activity
relationship for beta-amyloid, aggregation properties of an overlapping series of synthetic
beta-amyloid peptides (beta APs) were investigated and compared with beta AP neurotoxic …
