By combining KLVFF peptide and self-assembly chaperone we fabricate a new system to achieve the synchronization between Aβ fibril disaggregation and reducing toxicity of Aβ 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.
通过将KLVFF肽与自组装伴侣蛋白相结合,我们构建了一个新系统,以实现Aβ纤维解聚与降低由此形成的Aβ片段(单体或寡聚体)毒性之间的同步。当KLVFF肽将纤维解聚成片段时,自组装伴侣蛋白的疏水结构域会立即同时与它们结合。这种结合阻止了片段的重新聚集及其与细胞的相互作用,从而降低了这些危险片段 的毒性。
