![]() Superoxide radical and NO are the most commonly synthesized reactive species produced by NADPH oxidases and NO synthases, respectively. Free radicals such as ROS and RNS arise as intermediates in many metabolic processes, are generated specifically as part of a cellular defense mechanism against invaded pathogens, and regulate several processes including glucose metabolism, cellular growth, and proliferation. Besides ROS, reactive nitrogen species (RNS), including nitric oxide (NO), peroxynitrite (NO 3 −), S-nitrosothiols also contribute to the generation of free radicals. ![]() Major ROS include superoxide anion (O 2 −), hydrogen peroxide (H 2O 2), and hydroxyl radical ( In biological systems, the term free radicals mostly refers to reactive oxygen species (ROS) and are oxygen centered. Alterations in transcriptional activity of various pathways, including nuclear factor erythroid 2-related factor 2, glycogen synthase kinase 3β, mitogen activated protein kinase, nuclear factor kappa B, and reduced activity of superoxide dismutase, catalase and glutathione with aging might be correlated with the increased incidence of PD.Ĭhemical species with unpaired or an odd number of electrons are called free radicals. Moreover, neurons encounter more oxidative stress as a counteracting mechanism with advancing age does not function properly. Oxidative damage includes mitochondrial dysfunction, dopamine auto-oxidation, α-synuclein aggregation, glial cell activation, alterations in calcium signaling, and excess free iron. ![]() Here, we enumerate the common link between aging and PD at the cellular level with special reference to oxidative damage caused by free radicals. Dopaminergic neurons show linear fallout of 5–10% per decade with aging however, the rate and intensity of neuronal loss in patients with PD is more marked than that of aging. There is an age-associated increase in oxidative damage to the brain, and aging is considered a risk factor for PD.
