报告摘要：Peptide self-assembly has attracted great interest due to its important role in the design of novel biomaterials and its close link with many ageing-related degenerative diseases (such as Alzheimer’s disease and type 2 diabetes). Inhibition of the pathological self-assembly of proteins and disruption of preformed proto?brils by natural small molecules are two major attractive strategies in combating amyloidosis diseases. Deciphering the microscopic mechanisms of peptide self-assembly and amyloid fibril inhibition is of fundamental importance for the design of peptide-based bio-nanomaterials and the development of potent inhibitors targeting the fibril formation of amyloid proteins. Molecular dynamic (MD) simulations play an essential role by allowing generation of sufficiently accurate conformational ensembles which can be used to interpret experimental observations, predict new nanostructures and reveal the molecular interaction mechanisms. Here, I present our recent MD simulation results of the self-/co-assembly of ultra-short peptides and the molecular mechanisms by which natural small molecules disrupt A? protofibrils - the intermediates of the A? fibril formation and elongation.
