They play an important role in many neuronal functions, including synaptic plasticity, synaptogenesis, and memory. The ionotropic glutamate receptors are an extremely diverse group of receptors. 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). Accumulating evidence indicates that phasic burst firing is largely driven by NMDAR activation (Morikawa & Paladini, 2011; Overton & Clark, 1997). 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 Glutamate exerts its effects by binding to and activating cell surface receptors.
Glial glutamate receptors and transporters are key molecules that sense synaptic activity and by these means modify their physiology in the short and long term. Posttranslational modifications that regulate protein-protein interactions and modulate transmitter removal NMDA and AMPA/kainate glutamatergic receptors in the prelimbic medial prefrontal cortex modulate the elaborated defensive behavior and innate fear-induced antinociception elicited by GABAA receptor blockade in the medial hypothalamus. de Freitas RL(1), Salgado-Rohner CJ, Biagioni AF, Medeiros P, Hallak JE, Crippa JA, Coimbra NC. 2017-01-06 2015-06-22 Double labeling for GABA (B) receptor subunits and vesicular glutamate transporters revealed that labeling for both GABA (B1) and GABA (B2) was localized on glutamatergic axon terminals that expressed either vesicular glutamate transporter 1 or vesicular glutamate transporter 2. Glutamate receptors are transmembrane proteins, they are numerous and highly complex and can be divided into two main categories: voltage-sensitive ionotropic glutamate receptors (iGluRs), which are glutamate-gated ion channels, and ligand-sensitive metabotropic glutamate receptors (mGluRs), which are glutamate-activated G protein-coupled receptors (GPCRs). The role of ionotropic glutamatergic receptors in the mechanisms of neurotransmitter release, the transmission of nociceptive stimuli, morphine analgesia and tolerance has been well demonstrated in many studies.

The first allows the passage of ions through the postsynaptic membrane, while the metabotropic subtype activates signaling cascades through second messengers. Here, in mice, we identified that BLA cholecystokinin (CCK) glutamatergic neurons mediated negative reinforcement via D2 medium spiny neurons (MSNs) in the nucleus accumbens (NAc) and that chronic social defeat selectively potentiated excitatory transmission of the CCK BLA -D2 NAc circuit in susceptible mice via reduction of presynaptic cannabinoid type-1 receptor (CB 1 R). The glutamatergic system and its associated receptors have been implicated in the pathophysiology of MDD. In fact, the N-methyl-d-aspartate (NMDA) receptor, a glutamate receptor, is a binding or modulation site for both classical antidepressants and new fast-acting antidepressants. 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.
By contrast, glutamate receptor subunits GluA2, GluN1, GluN2A, and VGluT2 showed no changes in expression. These findings indicate that Aβ 1-42 induces brain region and layer specific expression changes of the glutamatergic receptors and transporters, suggesting complex and spatial vulnerability of this pathway during development of AD neuropathology.

NMDA receptor antagonists are a class of drugs that work to antagonize, or inhibit the action of, the N-Methyl-D-aspartate receptor ().They are commonly used as anesthetics for animals and humans; the state of anesthesia they induce is referred to as dissociative anesthesia..

Methods In rats prepared with chronic intrathecal catheters, the heel of one hind paw was exposed to a 52 degrees C surface for 45 s, resulting in a local erythema without blistering. Biochemical receptors for glutamate fall into three major classes, known as AMPA receptors, NMDA receptors, and metabotropic glutamate receptors.
