This essential molecule has three different receptors in the mammalian nervous system: NMDA, AMPA, and kainite receptors. All of these receptors allow the influx of Ca 2+ ions into the neuron. 2019-04-02 This study investigated synovial fluid glutamate concentrations and glutamate receptor (GluR) expression in injured human joints and compared the efficacy of GluR antagonists with current treatments in a mouse model of injury-induced osteoarthritis (ACL rupture). Glutamate receptor antagonists for tinnitus (Protocol) Imsuwansri T, Hoare DJ, Phaisaltuntiwongs W, Srisubat A, Snidvongs K Imsuwansri T, Hoare DJ, Phaisaltuntiwongs W, Srisubat A, Snidvongs K. The purpose of this study was to determine whether this apparent excitotoxicity can be attenuated by kynurenic acid (KYNA), a broad-spectrum glutamate receptor antagonist, and protect against noise-induced temporary threshold shifts (TTS). Guinea pigs were randomly assigned to three separate groups. Ethanol is an antagonist of the N-methyl-D-aspartate (NMDA) glutamate receptor. Ethanol dependence upregulates NMDA receptors and contributes to crosstolerance with selective NMDA receptor OBJECTIVE: A family history of alcoholism is a risk factor for the development of ethanol dependence.Ethanol is an antagonist of the N-methyl-d-aspartate (NMDA) glutamate receptor, and alterations in NMDA receptor function are thought to be involved in ethanol abuse and dependence.The purpose of this study was to determine in healthy individuals with no ethanol dependence whether … The effect of (E)-2-methyl-6-styryl-pyridine (SIB1893), a selective metabotropic glutamate (subtype 5) receptor (mGlu(5)R) antagonist, on glutamate release from isolated nerve terminals (synaptosomes) was examined.

NMDA receptors are members of the ionotropic class of glutamate receptors, which also includes Kainate and AMPA receptors. NMDA receptors are tetramers that consist of GluN1 subunits combined with GluN2 (A-D) or GluN3 (A-B) subunits.

The salient point here is that, of all the glutamate-receptor channels (there are three basic types) the NMDA receptor is the most sensitive to alcohol (Weight et al. 1993). Experiments show a 30 percent reduction in LTP at alcohol concentrations reached after only a single drink (Blitzer et al. 1990).
