Formation of Nanostructures by Peptides

摘要

Background: Amyloid fibrils, which are implicated in several diseases, are highly ordered structures formed by aggregation of proteins. Intriguingly, several short peptides, some of which are unrelated to the disease-causing proteins, also aggregate to form amyloid fibrils in vitro. The aggregation behavior of these short peptides can be modulated so that they form nanostructures that are not in any way related to amyloid fibrils. These observations have led to extensive research aimed at getting insights into how peptides aggregate to form amyloids as well as non-amyloidogenic structures.
