WebPolymerization of amyloid β-peptide (Aβ) into amyloid fibrils is a critical step in the pathogenesis of Alzheimer's disease. Here, we show that peptides incorporating a short Aβ fragment (KLVFF; Aβ) can bind full-length Aβ and prevent its assembly into amyloid fibrils. Through alanine substitution, it was demonstrated that amino acids Lys, Leu, and Phe are … WebThe release of the loaded DOX can be promoted by pH and laser stimulation. Compared with single therapy modality, the combination of chemotherapy and photothermal therapy showed higher cancer cell killing effect.

WebThe short Aβ fragment, KLVFF (Aβ 16–20 ), is crucial for Aβ assembly and considered to be an Aβ aggregation inhibitor. Here, we show that acetylation of KLVFF turns it into an extremely fast self-assembling molecule, reaching macroscopic ( i.e., mm) size in seconds. WebWhen 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 … WebAmyloidogenic peptide fragment KLVFF (H 2 N-Lys-Leu-Val-Phe-Phe-COOH, Aβ 16-20), the core-sequence of the polypeptide Aβ40, is a well-studied model for amyloid formation.However, due to its low crystallinity, detailed atomic information of KLVFF structure is lacking.
