2006-01-01 · Two glutamate receptor subtypes at the NMJ. Glutamate receptors containing either the DGluRIIA (left) or DGluRIIB (right) are physiologically different. The top two traces show single channel responses to the brief application of glutamate (upper line). While the current amplitude is the same, the IIB‐containing receptors desensitize more

In Caenorhabditis elegans , 10 putative ionotropic glutamate receptor subunits have been identified, a surprising number for an organism with only 302 neurons. discriminating between receptor subtypes remain surprisingly limited, since organic compounds highly selective for NR2A-, NR2C-, NR2D or NR3-containing receptors are still lacking. Compounds acting at the agonist-binding domains The first NMDAR antagonists were competitive antagonists acting at the glutamate binding site on the NR2 subunits. releasing glutamate into the synaptic cleft. Under normal conditions, synaptic glutamate can signal through ionotropic a-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs), N-methyl-D-aspar-tate receptors (NMDARs), and kainate receptors (KARs), or through metabotropic mGluR I, II, or III class receptors. The eight metabotropic glutamate receptors (mGluRs) serve critical modulatory roles throughout the nervous system. The molecular diversity of mGluRs is thought to be further expanded by the formation of heterodimers, but the co-expression of mGluR subtypes at the cellular level and the relative propensities of heterodimer formation are not well known.

metabotropic glutamate receptors include mGluR1 and mGluR5 subtypes, which activate phospholipase C and induce inositol triphosphate production and intracellular calcium mobilization. Our results demonstrate the expression of a variety of NMDA glutamate receptor subtypes in the lung and airways. With the use of RT-PCR and Western blotting as well, our data permit these conclusions: ( i ) NMDAR 1 mRNA was moderately expressed, and its protein was easily detectable by Western blot, in all regions of the lung and in airways. 1.

Amino acid residues that influence the properties of vertebrate iGluRs are also present in C. elegans subunits, including the "Q/R" site of non-NMDA receptors

With the use of RT-PCR and Western blotting as well, our data permit these conclusions: ( i ) NMDAR 1 mRNA was moderately expressed, and its protein was easily detectable by Western blot, in all regions of the lung and in airways. 1. Metabotropic glutamate receptors (mGluRs) are coupled to various second-messenger systems through guanosine 5'-triphosphate-binding proteins. To date, at least seven mGluRs have been cloned, and these mGluR subtypes can be divided into three major groups on the basis of similarities in amino acid sequence, coupling to second-messenger cascades in expression systems, and pharmacological Glutamate is the main excitatory neurotransmitter in the central nervous system (CNS) and is a major player in complex brain functions.

Glutamate is a fundamental excitatory neurotransmitter in the mammalian central nervous system (CNS), playing key roles in memory, neuronal development, and synaptic plasticity. Moreover, excessive glutamate release has been implicated in neuronal cell death. There are both ionotropic and metabotropic glutamate receptors (mGluRs), the latter of which can be divided into eight subtypes and
