oxidative 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 کاملEarly oxidative damage underlying neurodegeneration in X-adrenoleukodystrophy.
X-linked adrenoleukodystrophy (X-ALD) is a fatal neurodegenerative disorder, characterized by progressive cerebral demyelination cerebral childhood adrenoleukodystrophy (CCALD) or spinal cord neurodegeneration (adrenomyeloneuropathy, AMN), adrenal insufficiency and accumulation of very long-chain fatty acids (VLCFA) in tissues. The disease is caused by mutations in the ABCD1 gene, which encodes...
متن کاملOxidative Damage to RNA in Neurodegenerative Diseases
Since 1999, oxidative damage to RNA molecules has been described in several neurological diseases including Alzheimer's disease, Parkinson's disease, Down syndrome, dementia with Lewy bodies, prion disease, subacute sclerosing panencephalitis, and xeroderma pigmentosum. An early involvement of RNA oxidation of vulnerable neuronal population in the neurodegenerative diseases has been demonstrate...
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...
