Abstract

Derangements in glutamate neurotransmission have been implicated in several neurodegenerative disorders including, stroke, epilepsy, Huntington's disease, Alzheimer's disease, and amyotrophic lateral sclerosis (ALS). Activation of the N-methyl-D-aspartate (NMDA) receptor subtype of glutamate receptors results in the influx of calcium which binds calmodulin and activates neuronal nitric oxide synthase (nNOS), to convent L-arginine to citrulline and nitric oxide (NO). NO has many roles in the central nervous system as a messenger molecule, however, when generated in excess NO can be neurotoxic. Excess NO is in part responsible for glutamate neurotoxicity in primary neuronal cell culture and in animal models of stroke. It is likely that most of the neurotoxic actions of NO are mediated by peroxynitrite (ONOO-), the reaction product from NO and superoxide anion. In pathologic conditions, peroxynitrite and oxygen free radicals can be generated in excess of a cell antioxidant capacity resulting in severe damage to cellular constituents including proteins, DNA and lipids. The inherent biochemical and physiological characteristics of the brain, including high lipid concentrations and energy requirements, make it particularly susceptible to free radical and oxidant mediated insult. Increasing evidence indicates that many neurologic disorders may have components of free radical and oxidative stress induced injury.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
