Experiments in which two Neurotransmission in the hippocampus is modulated variously through presynaptic metabotropic glutamate receptors (mGluRs). To establish the precise localization of presynaptic mGluRs in the rat hippocampus, we used subtype-specific antibodies for eight mGluRs (mGluR1–mGluR8) for immunohistochemistry combined with lesioning of the three major hippocampal pathways: the perforant path, mossy AMPA–Kainate Subtypes of Glutamate Receptor in Rat Cerebral Microglia Mami Noda , Hiroshi Nakanishi , Junichi Nabekura , Norio Akaike Journal of Neuroscience 1 January 2000, 20 (1) 251-258; DOI: 10.1523/JNEUROSCI.20-01-00251.2000 2018-03-05 · Glutamate exerts diverse and complex effects in the CNS by binding to a large range of receptors with distinct structural and functional properties. Glutamate receptors are broadly divided into two groups, the cation-permeable ionotropic glutamate receptors (iGluR) and the G protein-coupled metabotropic glutamate receptors (mGluR). Glutamate receptor overactivation induces excitotoxic neuronal death, but the contribution of glutamate receptor subtypes to this excitotoxicity is unclear. We have therefore studied the expression of ionotropic glutamate receptor subunits and metabotropic glutamate receptor subtypes at the RNA and protein level in primary neuronal cultures derived from rat hippocampal, cortical and cerebellar tissue, and studied which of the mGlu receptors are expressed in secondary astrocyte cultures derived from rat cortex. 2009-11-29 · Sugiyama, H., Ito, I. & Watanabe, M.

doi: 10.1523/JNEUROSCI.1970-10.2011. Bath application of NMDA is commonly used to induce locomotor activity in spinalized zebrafish preparations. Although NMDA receptor activation is sufficient to induce organized locomotor activity, the roles that glutamate receptor subtypes play in the production of swimming are complex and not well understood.

1 . We investigated the agonist and antagonist activities of 22 new phenylglycine and phenylalanine derivatives for metabotropic glutamate receptors (mGluRs) by examining their effects on the signal transduction of mGluR 1, mGluR 2 and mGluR 6 subtypes expressed in Chinese hamster ovary cells. This analysis revealed several structural characteristics that govern receptor subtype specificity of

Zhang1,* ABSTRACT Multiple lines of evidence suggest that dysfunction of the metabotropic glutamate receptor subtype 5 (mGluR 5) plays a role in the pathogenesis of autism spectrum disorder (ASD).Yet animal and human investigations of mGluR 5 expression provide conflicting findings about the nature of dysregulation of cerebral mGluR 5 pathways in subtypes of ASD.

In mammalian retina, it appears that a particular glutamate receptor is localized in each subtype of OFF bipolar cell. Presumably, this contributes to the decomposition of the visual information relayed by photoreceptors. Less is known about glutamate receptor subtypes in mammalian and particularly primate horizontal cells.

Based on the selective agonists, the three major ligand gated subtypes of excitatory amino acid receptors identified and classified are, N-methyl-D-aspartate acid, alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid, and kainic acid receptors. title = "Metabotropic glutamate receptor subtypes as targets for neuroprotective drugs", abstract = "Metabotropic glutamate (mGlu) receptors have been considered as potential targets for neuroprotective drugs, but the lack of specific drugs has limited the development of neuroprotective strategies in experimental models of acute or chronic central nervous system (CNS) disorders.

Metabotropic glutamate receptors (mGluRs) modulate several G‐protein‐related signal transduction pathways including intracellular calcium (iCa2+) that control both neuronal development and demise. As an initial investigation, we characterized the ability of specific mGluR subtypes to modulate iCa2+ by using Fura‐2 microfluorometry in primary hippocampal neurons.

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 profiles.

2‐(Carboxycyclopropyl)glycines (CCGs) are conformationally restricted glutamate analogues and consist of eight isomers including l ‐ and d ‐forms. The agonist potencies and selectivities of these compounds for metabotropic glutamate receptors (mGluRs) were studied by examining their effects on the signal transduction of representative mGluR1, mGluR2 and mGluR4 subtypes in Chinese Metabotropic glutamate receptors, which belong to subfamily C of G protein-coupled receptors are divided into three groups, with a total of eight subtypes (in mammals; this is not necessarily the case for most organisms). Less is known about glutamate receptor subtypes in mammalian and particularly primate horizontal cells. Although immunohistochemistry indicates that both kainate and AMPA receptor subunits exist in bipolar and horizontal cells (Vardi et al., 1998), their physiological relevance is uncertain.
