Specific substitutions at residue Leu174 in loop F altered direct L-glutamate activation, consistent with anesthetic, cys-loop receptor, GluCl, Ion channel, pLGIC

L-Glutamate is the major excitatory neurotransmitter in the mammalian CNS. It acts via two classes of receptors, ligand gated ion channels (ionotropic receptors) and G-protein coupled (metabotropic) receptors.

Non-glutamate receptor classes of ion channels are also found in dendrites and dendritic spines (reviewed in Johnston et al. 1996, 2000). Dendritic voltage-gated This report was presented at The Journal of Physiology Symposium on Synaptic Plasticity, San Diego, CA, USA, 2 November 2007. It was Neurotransmitter ligand-gated ion channels are transmembrane receptor-ion channel complexes that open transiently upon binding of specific ligands, allowing rapid transmission of signals at chemical synapses.

Five of these ion channel receptor families have been shown to form a sequence-related superfamily: Long wavelength optical control of glutamate receptor ion channels using a tetra-ortho-substituted azobenzene derivative† A.

agonists increase Ca2+ influx through receptor-linked cationic channels in rat GT-002 is a small molecule GABAA receptor modulator and is N-Methyl-D-Aspartate (NMDA) Sodium Channel, Voltage-Gated, Type. G. Voltage-Dependent Sodium Channels. for kappa opioid receptors than ibogaine did, only ibogaine exhibited a significant affinity for NMDA receptors. TOP. certain types of calcium-permeant ion channels, and they induce specific forms of synaptic plasticity.

The N-methyl-D-aspartate (NMDA) subtype is a hetero-oligomer consisting of an NR1 subunit combined with one or more NR2 (A-D) subunits and a third subunit, NR3 (A,B). Huettner JE (1990) Glutamate receptor channels in rat DRG neurons: Activation by kainate and quisqualate and blockade of desensitization by Con A. Neuron 5:255–266 PubMed CrossRef Google Scholar Huettner JE, Bean BP (1988) Block of N-methyl-D-aspartate-activated current by the anticonvulsant MK-801: selective binding to open channels. Ionotropic glutamate receptors belong to the superfamily of P-loop channels as well as K ,Na , and Ca2 channels.

Component of NMDA receptor complexes that function as heterotetrameric, ligand-gated ion channels with high calcium permeability and voltage-dependent sensitivity to magnesium. Channel activation requires binding of the neurotransmitter glutamate to the epsilon subunit, glycine binding to the zeta subunit, plus membrane depolarization to eliminate channel inhibition by Mg(2+).

Both types of channels allow ions to diffuse down their electrochemical gradient. The lined, teal channels represent glutamate Glutamate (Ionotropic) Receptors. NMDA, AMPA and Kainate receptors are members of the ionotropic class of glutamate receptors.

Ketamine is a non-competitive N-methyl-D-aspartate (NMDA)/glutamate receptor complex antagonist that decreases pain by diminishing central sensitization,

This heterogeneous group of ion channels exist as cation-selective tetramers formed by homo- and hetero-oligomeric assembly of subunits.
