The expression of the NMDA subtype of glutamate receptors was investigated by Western blot analysis and RT-PCR in cultured chick Bergmann and Müller glial cells. Using subunit-specific antibodies directed to the carboxy terminus of the rat NMDAR2A/B we detected the expression of the NMDAR2 subunit in both kinds of culture. The functional subunit of the NMDA receptor, NMDAR1, was detected by mea...

NMDA receptors require both L-glutamate and the coagonist glycine for efficient channel activation. The glycine binding site of these heteromeric receptor proteins is formed by regions of the NMDAR1 (NR1) subunit that display sequence similarity to bacterial amino acid binding proteins. Here, we demonstrate that the glutamate binding site is located on the homologous regions of the NR2B subunit...

CDRI-08 is a standardized bacoside enriched ethanolic extract of Bacopa monnieri, a nootropic plant. We reported that CDRI-08 attenuated oxidative stress and memory impairment in mice, induced by a flame retardant, PBDE-209. In order to explore the mechanism, present study was designed to examine the role of CDRI-08 on the expression of NMDAR1 (NR1) and the binding of REST/NRSF to NR1 promoter ...

N-methyl-D-aspartate (NMDA) receptor-mediated synaptic transmission is implicated in activity-dependent developmental reorganization in mammalian brain, including sensory systems and spinal motoneuron circuits. During normal development, synaptic interactions important in activity-dependent modification of neuronal circuits may be driven spontaneously (Shatz 1990b). The respiratory system exhib...

This study was designed to determine whether hippocampal neuronal AMPA (alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid) and NMDA (N-methyl-D-aspartate) mRNA levels were differentially increased in temporal lobe epilepsy patients compared with those measured in control tissue from non-seizure autopsies. Hippocampi from hippocampal sclerosis patients (n = 28) and temporal mass lesion ca...
