This article identifies the important roles of selenium and calcium in the pathogenesis of Parkinson's disease. The antioxidant properties of selenium can affect calcium signaling and alleviate complications associated with oxidative stress.
Parkinson's disease (PD) is a neurological disorder in which oxidative stress and reactive oxygen species productions are proposed to be involved in its pathogenesis. Despite considerable advancement in Selenium's (Se) molecular biology and metabolism, we do not know much about the cell type-specific pattern of Se distribution in the brain of PD humans and experimental animals. Although, there is plenty of evidence around the role of Se deficiency in PD's pathogenesis impacting lipid peroxidation and reducing glutathione (GSH) and glutathione peroxidase (GPX). It has been suggested that Se has an inducible role in selenium-dependent GPX activity in PD animals and humans. However, calcium as a second messenger regulates the neuron cells' essential activities, but its overloading leads to cellular oxidative stress and apoptosis. Therefore, Se's antioxidant role can affect calcium signaling and alleviate its complications. There are signs of Se and Selenoproteins incorporation in protecting stress oxidative in various pathways. In conclusion, there is convincing proof for the crucial role of Se and Calcium in PD pathogenesis.
