The amino acid L-Glutamate acts as the most ubiquitous mediator of excitatory synaptic transmission in the central nervous system. Glutamatergic transmission is central for diverse brain functions, being particularly important for learning, memory, and cognition. In brain pathology, excessive release of glutamate triggers excitotoxic neural cell death

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 ...

Biochemistry (Moscow)
Astrocytic NMDA receptors (NMDARs) are heterotetramers, whose expression and properties are largely determined by their subunit composition. Astrocytic NMDARs are characterized by a low sensitivity to magnesium ions and low calcium conductivity. Their activation plays an important role in the regulation of various intracellular processes, such as gene ...

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.

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

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

Autoimmune NMDA receptor encephalitis
Clinica Chimica Acta, 2015Anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis is a treatable autoimmune disease of the central nervous system (CNS) with prominent neurologic and psychiatric features at disease onset. The disease is associated with the production of autoantibodies to NMDAR, a protein involved in memory function and synaptic plasticity. Affected patients
