The Effect of Conantokin G on NMDA Receptor-Mediated Spontaneous EPSCs in Cultured Cortical Neurons
Conantokin G (Con G), derived from the venom of Conus geographus, is the most characterized natural peptide antagonist targeted to NMDA receptors. Although Con G is known to bind to the glutamate binding site on the NR2 subunit of the receptor, it is unclear whether it can allosterically modulate the function of the receptor through the glycine binding site on the NR1 subunit. The present study...

متن کاملNitric oxide mediated the effects of nebivolol in cardiorenal syndrome
Objective(s): Despite several proposed mechanisms for the pathophysiology of cardiorenal syndrome (CRS), the exact mechanism remains unclear. Nitrosative stress has been argued as a key mechanism recently. Nebivolol is a beta-blocker with nitric oxide (NO)-releasing effect. In the present study, NO-mediated effects of two different treatment regimes of nebivolol in CRS...
متن کاملEffects of nitric oxide in cultured prevertebral sympathetic ganglion neurons.
The effects of the nitric oxide donor, S-nitrosoacetylpenicillamine (SNAP), were tested on cultured dissociated guinea pig celiac ganglion neurons using whole cell patch-clamp recordings. S-nitrosoacetylpenicillamine induced a concentration- and voltage-dependent inwardly directed shift in holding current (inward current shift) in 89% of neurons. The inward current shift was prevented by pre-tr...
متن کاملThe effect of ketamine on NMDA receptor-mediated LTP depends on ketamine effects on non-NMDA-mediated synaptic transmission in CA1 area of rat hippocampal slices
It has been reported that ketamine as an uncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist has also non-NMDA receptor antagonist properties. We recently found that ketamine (20 ?M) affected differently induction of NMDA receptor-mediated long-term potentiation (LTP) when administered 30 min prior to tetanic Primed-Bursts (PBs) stimulation. On the other hand, ketamine also influenced...
