GLUTAMATE RECEPTORS - svensk översättning - bab.la

On the role of metabotropic glutamate - AVHANDLINGAR.SE

Antidepressive Agents Glutamates Glycine Agents Receptors, N-Methyl-D-Aspartate Guanosine Ascorbic Acid Glutamate Receptors. 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. Activation of these receptors is responsible for basal excitatory synaptic transmission and many forms of synaptic plasticity such as long-term potentiation (LTP) and long-term depression (LTD), mechanisms that are thought to underlie learning and memory. Glutamate [NMDA] receptor subunits 1 and epsilon-2 (NMDAR1 and NMDAR2B) markers NMDA receptors are ion channels that are activated by glutamate and glycine.

During this restricted period of synaptic development, kainate-type of ionotropic glutamate receptors (KARs) are highly expressed in the BLA and tonically activated to regulate glutamate release via a G-protein-dependent mechanism. The most abundant GABA receptors in the CNS are ionotropic GABAA receptors, which are members of the superfamily of fast neurotransmitter-gated ion channels. This superfamily includes peripheral and neuronal nicotinic acetylcholine receptors (nAChRs), serotonin type 3A/B (5-HT 3A/B) receptors, and glycine receptors. The NMDA receptor, one of the ionotropic receptors for glutamate, is both a ligand-gated and voltage-dependent heterotetrameric ion channel, consisting of two NR1 and two NR2 subunits (Conti et al., 1999). Activation of the receptor results in the opening of the non-selective channel to the cations. The importance of understanding glutamatergic neurotransmission is emphasized, including discussion of ionotropic and metabotropic glutamate (GLU) receptors, GLU transporters, physiological functions of GLU neurotransmission, the role of calcium in age-related GLU neurotransmission and neurodegeneration, and the interaction of glial cells with Glutamate acts on two major classes of receptors: ionotropic receptors, which are ligand-gated ion channels, and metabotropic receptors (mGluRs), coupled to heterotrimeric G-proteins.

This diversity is generated both before and after gene transcription. Individual receptors are multimeric assemblies of subunits, transcribed from separate genes (eg GluN2A-D are produced from four genes). Glutamatergic input onto DA neurons activates both AMPA- and NMDA-type glutamate receptors (AMPARs and NMDARs).

Caffeine Interaction with Glutamate Receptor Gene - Altmetric

In spite of the different molecules that have been proposed to counteract excitotoxic damage, the participation of glutamatergic receptors in neuroprotection remains to be explored. To carry out its functions, glutamate acts via interaction with its cognate receptors, which are ligand-dependent. Glutamatergic receptors include ionotropic and metabotropic categories. The first allows the passage of ions through the postsynaptic membrane, while the metabotropic subtype activates signaling cascades through second messengers. Glutamatergic receptor blockade reduced excitability of broad- and narrow-spiking cells, of the 5 different cell groups identified by cluster analysis and of the specific response type a cell exhibited.

Glutamate receptors are the most abundant type of excitatory neurotransmitter receptors in the mammalian forebrain. Glutamate receptors are responsible for the excitatory drive in neuronal networks, and are uniquely involved in activating downstream signaling cascades required for synaptic plasticity, learning, and memory. Glutamate acts on two major classes of receptors: ionotropic receptors, which are ligand-gated ion channels, and metabotropic receptors (mGluRs), coupled to heterotrimeric G-proteins. Although several pharmacological evidences point to abnormal glutamatergic transmission in schizophrenia, changes in the expression of glutamatergic receptors in the prefrontal cortex of patients with schizophrenia remains equivocal.

Glutamate receptors are the primary mediators of excitatory transmission in the central nervous system and are mostly located on the dendrites of postsynaptic neuronal and glial cells, such as Glutamatergic input onto DA neurons activates both AMPA- and NMDA-type glutamate receptors (AMPARs and NMDARs). Accumulating evidence indicates that phasic burst firing is largely driven by NMDAR activation (Morikawa & Paladini, 2011; Overton & Clark, 1997). Glutamate exerts its effects by binding to and activating cell surface receptors. In mammals, four families of glutamate receptors have been identified, known as AMPA receptors, kainate receptors, NMDA receptors, and metabotropic glutamate receptors. The first three families are ionotropic, meaning that when activated they open membrane channels that allow ions to pass through.
