Amyloid β protein (Aβ) from Alzheimer's disease formed fibrillar aggregates and their morphology depended on oxidized and negatively charged liposomes. The morphology of fibrillar aggregates was affected by Cu 2+, together with their growth kinetics. This is because Cu 2+ inhibited the nucleation step in the formation of amyloid Aβ fibrillar aggregates by forming Aβ/Cu complex inactive to the growth of fibrillar aggregates. In addition, this is probably because Cu 2+ affected the fibrillar aggregate formed on the surface of liposomes. These findings would give a better understanding of the formation mechanism of amyloid fibrils on biomembranes.
