Résumé :

Friedreich's ataxia (FRDA) is a neurological disease related to a deficiency of the protein frataxin involved in iron-sulfur (Fe-S) cluster biogenesis. This leads to an increased cellular iron uptake accumulating in mitochondria, and a subsequently disturbed iron homeostasis. The detailed mechanism of iron regulation of frataxin expression is yet unknown. Deferiprone, an iron chelator that may cross the blood-brain barrier, was shown to shuttle iron between subcellular compartments. It could also transfer iron from iron-overloaded cells to extracellular apotransferrin and pre-erythroid cells for heme synthesis. Here, clinical studies on Deferiprone are reviewed in the context of alternative agents such as desferoxamine, with specific regard to its mechanistic and clinical implications.
