Strategy to discover full-length amyloid-beta peptide ligands using high-efficiency microarray technology.

ABSTRACT: Although the formation of β-amyloid (Aβ) fibrils in neuronal tissues is a hallmark of Alzheimer disease (AD), small-sized Aβ oligomers rather than mature fibrils have been identified as the most neurotoxic species. Therefore, the design of new inhibitors, able to prevent the aggregation of Aβ, is believed to be a promising therapeutic approach to AD. Unfortunately, the short-lived intermediate structures that occur in a solution along the Aβ aggregation pathway escape conventional experimental investigations and there is urgent need of new tools aimed at the discovery of agents targeting monomeric Aβ and blocking the early steps of amyloid aggregation. Here, we show the combination of high-efficiency slides (HESs) with peptide microarrays as a promising tool for identifying small peptides
