Amyloid fibrils are "alive": spontaneous refolding from one polymorph to another.

Dmitry Kurouski1, William Lauro, Igor K Lednev.   

Abstract

Mature fibrils prepared from apo-alpha-lactalbumin spontaneously refold from one polymorph to another as a result of a mild alteration in solution temperature and salinity. This discovery changes the very concept of the extraordinary stability of amyloid fibrils and presages a new approach for potentially regulating the biological activity of fibrils and their associated toxicity.
