Abstract: Here we present atomic force microscopy images of the fibrils formed by human amylin(20-29). This peptide is a fragment of the polypeptide amylin, the major proteinaceous component of amyloid deposits found in cases of type-II diabetes mellitus. Our results demonstrate that the amylin(20-29) peptide fragment forms amyloid-like fibrils that display polymorphic structures. Twisting along the axis of fibrils was often observed in fibrils aged for 6 hours but disappeared in mature fibrils aged for longer time periods.
