Iron overload contributes to the development of neurodegeneration and the exacerbation of normal apoptosis rates, largely due to its participation in the Fenton reaction and production of reactive oxygen species (ROS). Mitochondria constitute the major intracellular source of ROS and the main target of attack by free radicals. They are dynamic organelles that bind (fusion) and divide (fission) in...
