Unregulated cytosolic dopamine causes neurodegeneration associated with oxidative stress in mice.
The role of dopamine as a vulnerability factor and a toxic agent in Parkinson's disease (PD) is still controversial, yet the presumed dopamine toxicity is partly responsible for the "DOPA-sparing" clinical practice that avoids using L-3,4-dihydroxyphenylalanine (L-DOPA), a dopamine precursor, in early PD. There is a lack of studies on animal models that directly isolate dopamine as one determin...
متن کاملOxidative Stress in Neurodegeneration
It has been demonstrated that oxidative stress has a ubiquitous role in neurodegenerative diseases. Major source of oxidative stress due to reactive oxygen species (ROS) is related to mitochondria as an endogenous source. Although there is ample evidence from tissues of patients with neurodegenerative disorders of morphological, biochemical, and molecular abnormalities in mitochondria, it is st...
متن کاملoxidative stress and neurodegeneration
neurodegeneration is a complex and multifaceted process leading to many chronic disease states. a conventional definition implies a progressive neuronal death, which usually affects a specific population of nerve cells the vulnerability of which determines the clinical manifestations of a particular neurodegenerative disease. the neurodegenerative process is associated with many events. each ev...
متن کاملMitochondria, oxidative stress and neurodegeneration.
Mitochondria are involved in ATP supply to cells through oxidative phosphorylation (OXPHOS), synthesis of key molecules and response to oxidative stress, as well as in apoptosis. They contain many redox enzymes and naturally occurring inefficiencies of oxidative phosphorylation generate reactive oxygen species (ROS). CNS functions depend heavily on efficient mitochondrial function, since brain ...
متن کاملGlutathione, oxidative stress and neurodegeneration.
There is significant evidence that the pathogenesis of several neurodegenerative diseases, including Parkinson's disease, Alzheimer's disease, Friedreich's ataxia and amyotrophic lateral sclerosis, may involve the generation of reactive oxygen species and mitochondrial dysfunction. Here, we review the evidence for a disturbance of glutathione homeostasis that may either lead to or result from o...
