Excitotoxicity and mitochondria
Biochemical Society Symposia, 1999Excitotoxicity is the process whereby a massive glutamate release in the central nervous system in response to ischaemia or related trauma leads to the delayed, predominantly necrotic death of neurons. Excitotoxicity is also implicated in a variety of slow neurodegenerative disorders.

This review will summarize current understanding of the molecular and cellular mechanisms of excitotoxicity, the organization of glutamate systems in relation to ALS and evidence that excitotoxicity is relevant to the pathogenesis of ALS.

Excitotoxicity in the Pathogenesis of Autism
Neurotoxicity Research, 2012Autism is a debilitating neurodevelopment disorder characterised by stereotyped interests and behaviours, and abnormalities in verbal and non-verbal communication. It is a multifactorial disorder resulting from interactions between genetic, environmental and immunological factors.

Alternative excitotoxic hypotheses
Neurology, 1992The concept of excitotoxicity, neuronal death produced by overstimulation of excitatory amino acid receptors, has become a popular way of explaining the pathogenesis of neuronal death in a variety of acute and chronic neurologic diseases. While there is strong evidence supporting the role of excitotoxicity in acute processes such as hypoxia/ischemia ...

Excitotoxicity and neurodegenerative diseases
Current Opinion in Neurology, 1995Glutamate is an excitatory neurotransmitter in the mammalian central nervous system and a neurotoxin (excitotoxin) that has the potential to destroy neurones by activation of ionotropic receptors. In contrast to the well documented role of glutamate in the pathogenesis of neuronal degeneration resulting from hypoxia/ischaemia, hypoglycaemia, status ...

Pathophysiology of oligodendroglial excitotoxicity
Journal of Neuroscience Research, 1996Oligodendrocyte-like cells (OLD) derived from the rat oligodendroglial precursor line, CG-4, express Ca(2+)-permeable non-methyl-D-aspartate glutamate receptor channels (GluR). Exposure to kainate, an L-glutamate analogue, markedly elevates OLC Ca2+ influx and cytosolic [Ca2+], and results in damage to both OLC plasma membrane and OLC nuclear DNA.

Excitotoxins are a special group of neurotoxic substances that excite somatic and dendritic receptors in such a way that the neurons may die. All excitotoxins are in principle agonists of glutamate receptors in the brain and are structurally related to glutamate.
