There are two basic types of neural receptor: ionotropic, and metabotropic. There are many specific subtypes of glutamate receptors, and it is customary to refer to primary subtypes by a chemical which binds to it more selectively than glutamate. Glutamate, the major excitatory neurotransmitter in the brain, acts primarily on two types of ionotropic receptors: α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors and N -methyl-d-aspartate (NMDA) receptors. Work over the past decade indicates that regulated changes in the number of synaptic AMPA receptors may serve as a mechanism for information storage. Recent studies Mechanisms of Dopamine D1 Receptor-Mediated ERK1/2 Activation in the Parkinsonian Striatum and Their Modulation by Metabotropic Glutamate Receptor Type 5. The Journal of neuroscience : the official journal of the Society for Neuroscience , 34 (13), 4728-4740. Fast excitatory synaptic transmission in the central nervous system relies on the AMPA-type glutamate receptor (AMPAR).

Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors. Signaling inhibits adenylate cyclase activity. Many invertebrates, such as disease-causing parasitic worms, rely on glutamate-gated chloride channels, which are widely found in many types of nerves, including those controlling locomotion, feeding and sensing. The one shown here, from PDB entry 3rif , is an inhibitory channel from a roundworm.

Proteome diversification by adenosine to inosine RNA-editing
Most ionotropic glutamate receptors are located postsynaptically, although some are located presynaptically and on glia cells as well ( Fig. 2 ). Introduction to ionotropic glutamate receptors iGluRs are found on pre- and postsynaptic cell membranes, primarily within the CNS 1 and are divided into AMPA receptors, NMDA receptors and kainate receptors.

Glutamate is a fundamental excitatory neurotransmitter in the mammalian central nervous system (CNS), playing key roles in memory, neuronal development, and synaptic plasticity.
Report on a consanguineous family with autosomal recessive childhood onset of cerebellar ataxia and delayed psychomotor development. Type 1 metabotropic glutamate receptors (mGluR1s) are key elements in neuronal signaling. While their function is well documented in slices, requirements for their activation in vivo are poorly understood. We examine this question in adult mice in vivo using 2-photon imaging of cerebellar molecular layer interneurons (MLIs) expressing GCaMP.

GLUTAMATE RECEPTORS - svensk översättning - bab.la
They are classified as being either ionotropic (voltage-sensitive), or metabotropic (ligand Metabotropic glutamate receptors are known to act as modulators of (affect the activity of) other receptors. For example, group I mGluRs are known to increase the activity of N -methyl- D -aspartate receptors (NMDARs),   a type of ion channel-linked receptor that is central in a neurotoxic process called excitotoxicity . There are several types of glutamate ionotropic receptors including AMPA, kainate, and NMDA-receptor subunits.
