While there is evidence that iron may play a pathogenic role in both type 2 diabetes mellitus and Alzheimer’s disease, this can be extended to other biometals. For example, zinc transport has been suggested as a therapeutic target in type 2 diabetes mellitus [1]. Similarly, a role for zinc transporters has been proposed for Alzheimer’s and Pick’s disease [2]. Copper is a third biometals which has been implicated in both diseases [3, 4].
