Interactions between NMDA receptors (NMDARs) and the PDZ [postsynaptic density-95 (PSD-95)/Discs large/zona occludens-1] domains of PSD-95/SAP90 (synapse-associated protein with a molecular weight of 90 kDa) family proteins play important roles in the synaptic targeting and signaling of NMDARs. However, little is known about the mechanisms that regulate these PDZ domain-mediated interactions. H...
Retinal ganglion cells (RGCs) receive excitatory glutamatergic input from ON and OFF bipolar cells in distinct sublaminae of the inner plexiform layer (IPL). AMPA and NMDA receptors (AMPARs and NMDARs) mediate excitatory inputs in both synaptic layers, but specific roles for NMDARs at RGC synapses remain unclear. NMDARs comprise NR1 and NR2 subunits and are anchored by membrane-associated guany...
Tbr-1, a neuron-specific T-box transcription factor, plays a critical role in brain development. Here, we performed a computational search using the non-palindromic T-box binding sequence, namely the non-palindromic T-element, to determine the putative downstream target genes of Tbr-1. More than 20 identified genes containing the non-palindromic T-element in the 5' regulatory region were found ...
Emerging evidence has suggested that glycogen synthase kinase 3 (GSK-3) is a key regulatory kinase involved in a plethora of processes in the nervous system, including neuronal development, mood stabilization, and neurodegeneration. However, the cellular mechanisms underlying the actions of GSK-3 remain to be identified. In this study, we examined the impact of GSK-3 on the N-methyl-D-aspartate...
Whereas ifenprodil has been used as a selective GluN1/GluN2B (NR1/NR2B, B-type) receptor antagonist to distinguish between GluN2B (NR2B) and GluN2A (NR2A)-containing N-methyl-d-aspartate receptors (NMDARs), TCN 201 (3-chloro-4-fluoro-N-[4-[[2-(phenylcarbonyl)hydrazino]carbonyl]benzyl]benzenesulphonamide) and TCN 213 [N-(cyclohexylmethyl)-2-[{5-[(phenylmethyl)amino]-1,3,4-thiadiazol-2-yl}thio]ac...
While the spatiotemporal development of Tau pathology has been correlated with occurrence of cognitive deficits in Alzheimer's patients, mechanisms underlying these deficits remain unclear. Both brain-derived neurotrophic factor (BDNF) and its tyrosine kinase receptor TrkB play a critical role in hippocampus-dependent synaptic plasticity and memory. When applied on hippocampal slices, BDNF is a...
In visual cortex, NMDA receptor (NMDAR) properties depend primarily on NR2A and NR2B subunits, and NR2 subunit composition changes with age and visual experience. We examined the roles of these NR2 subunits in activity-dependent long-term modification of synaptic responses, which were evoked in layer 2/3 cells by stimulation of layer 4 in rat visual cortical slices. We used theta-burst stimulat...
NMDA receptors (NMDARs) play a distinct role at excitatory glutamatergic synapses, where they are usually localized with other ionotropic glutamate receptors, including tors. Two features are essential to their specialized roles in synaptic plasticity and the excitodependent magnesium block, the removal of which requires depolarization of the membrane potential. Second, upon activation, the NMD...
KIF17, a recently characterized member of the kinesin superfamily proteins, has been proposed to bind in vitro to a protein complex containing mLin10 (Mint1/X11) and the NR2B subunit of the NMDA receptors (NMDARs). In the mammalian brain, NMDARs play an important role in synaptic plasticity, learning, and memory. Here we present, for the first time, the dynamic properties of KIF17 and provide e...
NMDA receptors (NMDARs) are important for neuronal development and circuit formation. The NMDAR subunits NR2A and NR2B are biophysically distinct and differentially expressed during development but their individual contribution to structural plasticity is unknown. Here we test whether NR2A and NR2B subunits have specific functions in the morphological development of tectal neurons in living Xen...
