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 ...

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

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).

STUDIES OF NMDA- AND NON-NMDA-MEDIATED NEUROTOXICITY IN CULTURED NEURONS
Neurochemistry International, 1996The neurotoxic effects of various glutamate agonists were studied using whole fetal rat brain cultures. The results showed that L-glutamate (L-glu) and N-methyl-D-aspartate (NMDA) were the most potent agonists for inducing neurotoxicity, producing significant toxicity at 0.10 and 0.01 mM concentrations, respectively.

General Pharmacology: The Vascular System, 1993
1. Beginning with electrophysiological evidence for two populations of receptors for N-methyl-D-aspartate (NMDA) which did or did not respond to the agonist quinolinic acid, evidence has grown for such subdivision. 2. Data from binding studies is consistent with differences between three NMDA receptors in the striatum, thalamus and cerebellum with ...

Fundamental & Clinical Pharmacology, 1993
Summary—The synaptic responses elicited by glutamate and aspartate in the CNS are mediated by distinct groups of receptors which include the ionotropic NMDA receptor. The NMDA receptor is activated by high‐strength synaptic input and produces relatively sustained depolarization which can lead to repetitive burst firing.

Brief periods of anoxia cause a marked, but apparently fully reversible interruption of integrated brain function, whose cellular mechanism is not yet fully understood. For some 50 years it has been known that the hippocampus is one of the first brain regions to be affected by anoxia (Sugar and Gerard 1937).

Determination of NMDA NR1 subunit copy number in recombinant NMDA receptors
Proceedings of the Royal Society of London. Series B: Biological Sciences, 1995Co-expression of wild-type and mutated NMDA NR1 (N598R) subunits in Xenopus oocytes has been used to determine the stoichiometry of the NMDA receptor-channel. When expressed together, wild-type NR2A and mutant NR1 (N598R) subunits produced channels with a main conductance of 2.6 pS and a sublevel of 1.2 pS.
