Most of the clinical effects can be explained by the interaction of ethanol with various neurotransmitters and neuroreceptors in the brain, including those interacting with gamma-aminobutyric acid (GABA), glutamate (NMDA), and opiates. (medscape.com)
Sodium ions4
Upon binding glutamate, they permit calcium and sodium ions, respectively, to flow into the cell. (brainfacts.org)
It is well-established that the secondary active transporters Glt Tk and Glt Ph catalyze coupled uptake of aspartate and three sodium ions, but insight in the kinetic mechanism of transport is fragmentary. (nature.com)
Here, we systematically measured aspartate uptake rates in proteoliposomes containing purified Glt Tk , and derived the rate equation for a mechanism in which two sodium ions bind before and another after aspartate. (nature.com)
These experiments have indicated that most likely two sodium ions bind first, then aspartate, and finally the third sodium ion. (nature.com)

PPDA is a subtype-selective NMDA receptor antagonist that preferentially binds to GluN2C/GluN2D (formally NR2C/NR2D) containing receptors (K i values are 0.096, 0.125, 0.31 and 0.55 μ M for GluN2C, GluN2D, GluN2B and GluN2A subunits respectively). (tocris.com)
Glutamate (Glu), the major excitatory neurotransmitter, elicits its action through the activation of membrane receptors and transporters expressed in neurons and glial cells. (intechopen.com)

v DISSERTATION ABSTRACT DIFFERENTIAL MODULATION OF GLUTAMATERGIC SYNAPTIC TRANSMISSION BY POLYSIALIC ACID Catrina Sims-Robinson Doctor of Philosophy, December 17, 2007 (B.S., Auburn University, 2004) 180 Typed Pages Directed by Vishnu Suppiramaniam Controlled modulation and regulation of glutamate receptors are essential for synaptogenesis and synaptic plasticity. (auburn.edu)
The two major types of excitatory glutamate receptors found at the synapse are AMPA and NMDA, which during over-activation leads to glutamate induced excitotoxicity. (auburn.edu)
There are several studies that established a link between PSA-NCAM and glutamate vi receptors. (auburn.edu)
However, the mechanisms whereby PSA-NCAM modulates glutamate receptors have not been studied. (auburn.edu)
Therefore, this study will investigate the effects of endogenous and soluble PSA-NCAM on synaptic glutamate receptors. (auburn.edu)
Elucidating the functional properties of single synaptic glutamate receptors and the modulation of these receptors by PSA will be a step towards understanding many neurodegenerative disorders where PSA expression is altered. (auburn.edu)
PSA also inhibited with the binding of glutamate to NR2B subunit- containing NMDA receptors. (auburn.edu)

Ketamine works by binding to the N-methyl-d-aspartate, or NMDA receptors. (seattleregen.com)
This means that it binds these receptors and prevents them from being overstimulated. (seattleregen.com)
When ketamine enters the brain, it binds to the N-methyl-D-aspartate receptor (NMDA) receptors, ultimately causing a surge of glutamate. (headinghealth.com)
Ketamine is believed to target N-Methyl-D-Aspartate (NMDA) receptors in the brain. (tallyclinics.com)
By binding to these receptors, Ketamine appears to increase the number of neurotransmitters called glutamine in the space between neurons. (tallyclinics.com)
It binds to opioid receptors and acts as a pain relief medication in the Central Nervous System. (tallyclinics.com)
When Ketamine is introduced into the central nervous system via intravenous infusions, it binds onto the NMDA receptor, causing an increase of circulating glutamate. (cicus.org)
