...Ana Pavić; Alexandra O. M. Holmes; Vincent L. G. Postis; Adrian Goldman Glutamate transporters play important roles in bacteria, archaea and eukaryotes. Their function in the mammalian central nervous system is essential for preventing excitotoxicity, and their dysregulation is implicated in many...

... homoeostasis. GS (glutamine synthetase), which catalyses the ATP-dependent condensation of ammonia and glutamate to form glutamine, is an enzyme particularly found in astrocytes. GS plays a pivotal role in glutamate and glutamine homoeostasis, orchestrating astrocyte glutamate uptake/release and the glutamate...

...David G. Nicholls Chronic exposure to glutamate (glutamate excitotoxicity) exacerbates neuronal damage in the aftermath of stroke and is implicated in a variety of neurodegenerative disorders. Mitochondria play a central role in the survival or death of the exposed neuron. Calcium, oxidative stress...

...G.P. Reynolds; M.K. Harte There is an accumulation of evidence for abnormalities in schizophrenia of both the major neurotransmitter systems of the brain – those of GABA (γ-aminobutyric acid) and glutamate. Initial studies have found deficits in the putative neuronal marker, N -acetylaspartate, in...

...R. Simon; Z. Xiong Intracellular calcium toxicity remains the central feature in the pathophysiology of ischaemic cell death in brain. Glutamate-gated channels have been thought to be the major sites of ischaemia-induced toxic calcium entry, but the failure of glutamate antagonists in clinical...

Almost 90°% of l cystine transport is by a low-affinity, sodium-dependent mechanism ( K m = 473 ± 146 μM), that is mediated by the X AG -family of glutamate transporters. Both l glutamate (IC 50 = 9.1 ± 0.4 μM) and l cysteine...
