N-methyl-(D)-aspartate (NMDA) receptors are heteromultimeric ion channels that contain an essential GluN1 subunit and two or more GluN2 (GluN2A-GluN2D) subunits. The biophysical properties and physiological roles of synaptic NMDA receptors are dependent on their subunit composition. In the basolateral amygdala (BLA), it has been suggested that the plasticity that underlies fear learning require...
Interactions between dopaminergic and glutamatergic afferents in the striatum are essential for motor learning and the regulation of movement. An important mechanism for these interactions is the ability of dopamine, through D1 receptors, to potentiate NMDA glutamate receptor function. Here we show that, in striatal neurons, D1 receptor activation leads to rapid trafficking of NMDA receptor sub...
background: considering that cannabinoids protect neurons against neurodegeneration, in this study, the neuroprotective effect of win55,212-2 in paraoxon induced neurotoxicity in pc12 cells and the role of the n-methyl-d-aspartate (nmda) receptor were evaluated. materials and methods: in this study pc12 cells were maintained in dulbecco's modified eagle’s medium (dmem+f12) culture medium supple...
Toluene abuse during pregnancy results in newborns with fetal solvent syndrome. N-Methyl-D-aspartate (NMDA) receptor has been identified as a target site for toluene. Since the normal function of NMDA receptor is critical for synaptogenesis, the long-term effects of toluene exposure during synaptogenesis on the neurobehavioral function and the expression of NMDA receptor subunits (NR1, NR2A, an...
NMDA receptors are glutamate-gated ion channels that play important roles in synaptic transmission and excitotoxicity. The functional NMDA receptor is thought to be a heterotetramer composed mainly of two NR1 and two NR2 subunits. Although it is generally accepted that only correctly assembled NMDA receptors can pass the ER quality control, the mechanism underlying this process is not well unde...
Interleukin (IL)-1beta is a proinflammatory cytokine implicated in various pathophysiological conditions of the CNS involving NMDA receptor activation. Circumstantial evidence suggests that IL-1beta and NMDA receptors can functionally interact. Using primary cultures of rat hippocampal neurons, we investigated whether IL-1beta affects NMDA receptor function(s) by studying (1) NMDA receptor-indu...
BACKGROUND N-methyl-D-aspartate (NMDA) receptors play a central role in glutamatergic synaptic transmission in the mammalian brain and are linked to the pathophysiology and symptomatology of Parkinson's disease (PD). However, changes in NMDA receptor expression in distinct subcellular compartments in PD have not been elucidated. In this study, we investigated changes in subcellular expression o...
We are interested in studying the co-localization of NMDA glutamate receptor subunits (NR1, NR2A/B) and AMPA glutamate receptor subunits (GluR1, GluR2, GluR2/3 and GluR4) in individual neurons of the rat vestibular nuclei. Immunoreactivity for NR1, NR2A/B, GluR1, GluR2, GluR2/3 and GluR4 was found in the somata and dendrites of neurons in the four major subdivisions (superior, medial, lateral, ...
anti-n-methyl-d-aspartate receptor (anti-nmdar) encephalitis is is most common form ofimmune-mediated encephalitis with prominent neurologic and psychiatric features at disease onset. we describe a 16 years old patient who presented with fever and status epilepticus. his mri sequences was normal. anti-nmdar antibodies were detected in the csf. mri, ct and other studies didn,t show any tumor.
Recent work has shown substantial alterations in NMDA receptor subunit expression, assembly, and phosphorylation in the dopamine-depleted striatum of a rodent 6-hydroxydopamine model of Parkinson's disease. These modifications are hypothesized to result from the trafficking of NMDA receptors between subcellular compartments. Here we show that in rat striatal tissues the NR2A and NR2B subunits i...
