Iron and calcium in the central nervous system: a close …

Iron and calcium are required for general cellular functions, as well as for specific neuronal-related activities. However, a pathological increase in their levels favours oxidative stress and mitochondrial damage, leading to neuronal death. Neurodegeneration can thus be determined by alterations in ionic homoeostasis and/or pro-oxidative–antioxidative equilibrium, two conditions that vary
