Abstract

By combining KLVFF peptide and self-assembly chaperone we fabricate a new system to achieve the synchronization between Ab fibril disaggregation and reducing toxicity of Ab fragments (monomers or oligomers) that consequently formed. When the KLVFF peptides disaggregate fibrils into fragments, the hydrophobic domains of self-assembly chaperones promptly bind them at the same time. This binding blocks the re-aggregation of the fragments and their interaction with cells, and hence reduces the toxicity of these dangerous fragments.
