Benzodiazepines (BDZs) are known to increase the amplitude and duration of IPSCs. Moreover, at low [GABA], BDZs strongly enhance GABAergic currents suggesting the up-regulation of agonist binding while their action on gating remains a matter of debate. In the present study we have examined the impact of flurazepam and zolpidem on mIPSCs by investigating(More)
Benzodiazepines are known to act by enhancing the effect of gamma-aminobutyric acid-A receptor agonists. Positive modulation by benzodiazepines is typically ascribed to upregulation of agonist binding affinity but their effect on gamma-aminobutyric acid-A receptor gating remain unclear. In this work, we have used the ultrafast application system to examine(More)
Enolase (EC 4.2.1.11) is an enzyme of the glycolytic pathway catalyzing the dehydratation reaction of 2-phosphoglycerate. In vertebrates the enzyme exists in three isoforms: alpha, beta and gamma. The amino-acid and nucleotide sequences deposited in the GenBank and SwissProt databases were subjected to analysis using the following bioinformatic programs:(More)
BACKGROUND AND PURPOSE Benzodiazepines (BDZs) are widely used in clinical practice and are known as positive modulators of GABAergic currents. BDZs increase binding affinity and recently they were found to affect GABA(A) receptor gating, including desensitization. Binding and desensitization are also strongly modulated by extracellular pH, a factor that may(More)
