Aluminium is an element suspected to contribute to the pathogenesis of Alzheimer's disease, but its mechanism of action is not clear. Neuropeptide Y (NPY) plays a significant role in feeding behaviour. Our spectroscopic, ELISA, and western blot studies indicate that aluminium interacts with neuropeptide Y and alters significantly the a-helical content. We found that aluminium reduced levels of NPY in the hypothalamus of aged rabbits. NPY polyclonal antibody interaction was found to depend upon the alpha-helical content of NPY. These results clearly show that aluminium alters NPY structure and this could explain the abnormality in feeding behaviour seen in patients with Alzheimer's disease.
