Bicine promotes rapid formation of ?-sheet-rich amyloid-? fibrils.

ABSTRACT: Fibrillar aggregates of amyloid-? (A?) are the main component of plaques lining the cerebrovasculature in cerebral amyloid angiopathy. As the predominant A? isoform in vascular deposits, A?40 is a valuable target in cerebral amyloid angiopathy research. However, the slow process of A?40 aggregation in vitro is a bottleneck in the search for A?-targeting molecules. In this study, we sought a method to accelerate the aggregation of A?40 in vitro, to improve experimental screening procedures. We evaluated the aggregating ability of bicine, a biological buffer, using various in vitro methods. Our data suggest that bicine promotes the aggregation of A?40 with high speed and reproducibility, yielding a mixture of aggregates with significant ?-sheet-rich fibril formation and toxicity.
