Cuprizone Administration Alters the Iron Metabolism in the Mouse Model of Multiple Sclerosis.

ABSTRACT: Cuprizone (CZ) is a widely used copper chelating agent to develop non-autoimmune animal model of multiple sclerosis, characterized by demyelination of the corpus callosum (CC) and other brain regions. The exact mechanisms of CZ action are still arguable, but it seems that the only affected cells are the mature oligodendrocytes, possibly via metabolic disturbances caused by copper deficiency. During the pathogenesis of multiple sclerosis, high amount of deposited iron can be found throughout the demyelinated areas of the brain in the form of extracellular iron deposits and intracellularly accumulated iron in microglia. In the present study, we used the accepted experimental model of 0.2% CZ-containing diet with standard iron concentration to induce demyelination in the brain of C57BL/6 mice
