Abstract:Transient forebrain or global ischemia in rats induces selective and delayed damage of hippocampal CA1 neurons. In a previous sludy, we have shown that expression of GIuR2, the kainate/a‐amino‐3‐hydroxy‐5‐ methyl‐4‐isoxazolepropionic acid (AMPA) receptor subunit that governs Ca′ permeability, is preferentially reduced in CA1 at a time point ...

The actions of glutamate, the major excitatory amino acid in the CNS, are mediated by three receptor subtypes: kainate, quisqualate and N-methyl-D-aspartate (NMDA) receptors. Ethanol, in vitro, is a potent and selective inhibitor of the actions of agonists at the NMDA receptor.

Current Opinion in Neurobiology, 2004
Dynamic modulation of the number of postsynaptic glutamate receptors is considered one of the main mechanisms for altering the strength of excitatory synapses in the central nervous system (CNS). However, until recently N-methyl-d-aspartate (NMDA) receptors were considered relatively stable once in the plasma membrane, especially in comparison with ...

Synapse, 1991
AbstractIdentified crayfish visual interneurons respond to illumination with a compound EPSP of up to 40 mV. L‐gultamate, quisqualate, and kainate mimic the depolarizing action of the natural transmitter. In reduced Mg2+, N‐methyl‐D‐aspartate (NMDA) elicits a depolarization with a reversal potential (Erev) = −60 mV. Erev is independent of extracellular

NMDA receptors and schizophrenia
Current Opinion in Pharmacology, 2007The pathophysiology of schizophrenia is poorly understood but is likely to involve alterations in excitatory glutamatergic signaling molecules in several areas of the brain. Clinical and experimental evidence has shown that expression of the N-methyl-D-aspartate (NMDA) receptor and intracellular NMDA receptor-interacting proteins of the glutaminergic ...

NMDA Receptor Antagonists and Glycine Site NMDA Antagonists
Current Medical Research and Opinion, 2002Extracellular concentrations of excitatory amino acids increase substantially within cerebral tissue beds exposed to ischaemic conditions. This leads to excessive stimulation of N-methyl-D-aspartate (NMDA) receptors, a major cerebral excitatory neurotransmitter receptor that likely plays a critical role in the propagation of ischaemic injury in neurons.

Annual Review of Pharmacology and Toxicology, 2003
The NMDA receptor (NMDAR) plays a central role in the function of excitatory synapses. Recent studies have provided interesting insights into several aspects of the trafficking of this receptor in neurons. The NMDAR is not a static resident of the synapse. Rather, the number and composition of synaptic NMDARs can be modulated by several factors.

A Fast Synaptic Potential Mediated by NMDA and Non-NMDA Receptors
Journal of Neurophysiology, 1997Wolszon, Laura R., Alberto E. Pereda, and Donald S. Faber. A fast synaptic potential mediated by NMDA and non-NMDA receptors. J. Neurophysiol. 78: 2693–2706, 1997. Excitatory synaptic transmission in the CNS often is mediated by two kinetically distinct glutamate receptor subtypes that frequently are colocalized, the N-methyl-d-aspartate (NMDA) and ...

Increased NMDA affinity of the H780Q mutant of the NMDA receptor
Inorganica Chimica Acta, 1996A point mutation within the coding sequence of the primary subunit of the N-methyl-d-aspartatge (NMDA) subtypr of glutamate receptor (glutamine substitution for histidine at position 780) exhibits a higher affinity for NMDA than the wild type receptor (EC50 5 versus 27 μM).

NMDA retseptorsüsteemid NMDA retseptorsüsteemid
2009N-metüül-D-aspartaadi (NMDA) retseptorite kaudu toimuv kaltsiumiioonide sissevool närvirakkudesse on vajalik närvisüsteemis toimuvateks füsioloogilisteks protsessideks. Selle süsteemi üleaktivatsiooni tingimustes suureneb markantselt postsünaptilistes neuronites intratsellullarse Ca2+ hulk ning see on neuronite degeneratsiooni üks võtmeprotsesse. Selle
