Abstract

A growing body of evidence supports a central role for biometals in neurodegenerative disorders. Biometals induce oxidative stress through the generation of reactive oxygen species and contribute to neuronal cell dysfunction in Alzheimer's disease (AD), prion disorders and Parkinson's disease (PD). Therapies based on modulation of biometal metabolism are currently being developed and the metal ligand, 5-chloro-7-iodo-8-hydroxyquinoline (clioquinol or CQ) has been investigated for the treatment of AD. CQ has also shown therapeutic benefits in an animal model of PD. However, little is known about the neuroprotective processes of CQ in vivo. In this study, we examined the effect of CQ in BE(2)-..
