NMDA receptors (NMDARs) are the major mediator of the postsynaptic response during synaptic neurotransmission. The diversity of roles for NMDARs in influencing synaptic plasticity and neuronal survival is often linked to selective activation of multiple NMDAR subtypes (NR1/NR2A-NMDARs, NR1/NR2B-NMDARs, and triheteromeric NR1/NR2A/NR2B-NMDARs). However, the lack of available pharmacological tool...
Since the discovery that a single dose of ketamine, an N-methyl-D-aspartate receptor (NMDAR) antagonist, had rapid and long-lasting antidepressant effects, there has been increased interest in using NMDAR modulators in the pharmacotherapy of depression. Ketamine's efficacy seems to imply that depression is a disorder of NMDAR hyperfunctionality. However, studies showing that not all NMDAR antag...
Glutamatergic synaptic transmission is mediated primarily through the AMPA-type glutamate receptor (AMPAR); the regulation of this receptor underlies many forms of synaptic plasticity. In particular, phosphorylation of GluR1, an AMPAR subunit, by PKA at serine 845 (S845) increases peak open channel probability and is permissive for both the synaptic expression of the receptor and NMDA-receptor ...
Abstract We investigated the feasibility of including plasma anti-NMDAR antibody screening in assessment first-episode psychosis patients an early intervention programme Southern hemisphere. Anti-NMDAR IgG antibodies were assessed by ELISA 166 (64.0% men), matched population-based controls and 76 patients’ siblings (30.3% men). Fisher’s exact test ANOVA performed. Positive more often observed b...
Excitatory-inhibitory (E/I) balance is essential for normal neural development, behavior and cognition. E/I imbalance leads to a variety of neurological disorders, such as autism schizophrenia. NMDA receptors (NMDARs) regulate AMPAR-mediated excitatory GABA A R-mediated inhibitory synaptic transmission, suggesting that NMDARs play an important role in the establishment maintenance balance. In t...
Schizophrenia is associated with disruptions in N-methyl-D-aspartate glutamate receptor subtype (NMDAR)-mediated excitatory synaptic signaling. The metabotropic glutamate receptor subtype 5 (mGlu5) is a closely associated signaling partner with NMDARs and regulates NMDAR function in forebrain regions implicated in the pathology of schizophrenia. Efficacy of mGlu5 positive allosteric modulators ...
NMDA receptor (NMDAR)-induced excitotoxicity is thought to contribute to the cell death associated with certain neurodegenerative diseases, stroke, epilepsy, and traumatic brain injury. Targeting NMDARs therapeutically is complicated by the fact that cell signaling downstream of their activation can promote cell survival and plasticity as well as excitotoxicity. However, research over the past ...
N-Methyl-D-aspartate (NMDA) receptor (NMDAR) activity regulates the net number of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors (AMPAR) at the cell surface by modulating the balance between AMPAR membrane insertion and endocytosis. In this study, we addressed the role of NMDAR subtypes and of NMDAR-mediated Ca2+ influx in the NMDAR-induced endocytosis of GluR2-contai...
