Edward J. Massaro and a panel of leading biomedical researchers and clinical practitioners review, in-depth, the status of our current knowledge concerning the biochemistry of copper in general and its role in health and disease in particular. Drawing on the wealth of new information emerging from the molecular biology revolution, these experts survey the most important research areas of copper pharmacology and toxicology, including copper proteins and transport, copper toxicity and therapeutics, and copper metabolism and homeostasis. They also discuss the molecular pathogenesis of copper in a variety of metabolic diseases, Menkes and Wilson’s diseases and occipital horn syndrome, as well as the role of copper in Parkinson’s disease, prion disease, familial amytrophic lateral sclerosis (ALS), and Alzheimer’s disease.
