TLDR
The molecular and functional diversity of the glutamate receptors is reviewed and their implications for integrative brain function are discussed.Abstract:
The glutamate receptors mediate excitatory neurotransmission in the brain and are important in memory acquisition, learning, and some neurodegenerative disorders. This receptor family is classified in three groups: the N-methyl-D-aspartate (NMDA), alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate (AMPA)-kainate, and metabotropic receptors. Recent molecular studies have shown that many receptor subtypes exist in all three groups of the receptors and exhibit heterogeneity in function and expression patterns. This article reviews the molecular and functional diversity of the glutamate receptors and discusses their implications for integrative brain function.read more

Stoichiometry of Recombinant N-Methyl-d-Aspartate Receptor Channels Inferred from Single-channel Current Patterns
TL;DR: The most straightforward interpretation of the results is that N-methyl-d-aspartate receptors are pentamers composed of three NR1 and two NR2 subunits, depending on whether or not the order of mutant and wild-type subunits influences the current pattern.

Neurotransmitters and their receptors in the islets of Langerhans of the pancreas: what messages do acetylcholine, glutamate, and GABA transmit?
Leslie S. Satin,Tracie A. Kinard +1 more
TL;DR: The putative roles of acetylcholine, glutamate, and GABA in islet function are proposed to mediate a novel paracrine signaling pathway whereby α- and β-cells communicate within the islet.
Journal ArticleDOI
Glutamate in neurologic diseases.
TL;DR: If glutamate antagonists in combination with agents that selectively inhibit the multiple steps downstream of the excitotoxic cascade or help improve intracellular energy metabolism may slow the neurodegenerative process and offer a therapeutic approach to treat these disorders, this work suggests.

Glutamate-evoked release of arachidonic acid from mouse brain astrocytes
TL;DR: It is demonstrated that in striatal astrocytes from mouse embryos, glutamate evokes a release of arachidonic acid and the glutamate-evoked release seems to be oppositely regulated by protein kinases A and C.

Ion channel associated proteins

TL;DR: Findings suggest that non-pore-forming subunits of ion channels may also have cell biological functions independent of their effects on channel electrophysiological properties.

TL;DR: Molecular cloning identified three complementary DNA species of rat brain, encoding NMDA receptor subunits NMDAR2A (NR2A), NR2B, and NR2C, which are 55 to 70% ientical in sequence, and these are structurally related, with less than 20% sequence identity, to other excitatory amino acid receptor sub Units.

TL;DR: A complementary DNA encoding the rat NMDA receptor has been cloned and characterized and it has been found that this protein has a significant sequence similarity to the AMPA/kainate receptors.

TL;DR: In neurons expressing certain KA-AMPA receptor subunits, glutamate may trigger calcium-dependent intracellular events by activating non-NMDA receptors.
