The respiratory and behavioral effects of the benzodiazepine receptor (BZR) inverse agonist ethyl-beta-carboline-3-carboxylate (beta-CCE) were determined alone and in combination with buspirone, lorazepam, flumazenil, and SR 95195 in rhesus monkeys. For the respiratory studies, one group of monkeys inhaled either

Benzodiazepine binding to gamma-aminobutyric acid type A (GABA(A)) receptors allosterically modulates GABA binding and increases the currents induced by submaximal GABA concentrations. Benzodiazepines induce conformational changes in the GABA-binding site in the extracellular domain, but it is uncertain whether these

We examined the effects of the inverse benzodiazepine agonist ethyl-beta-carboline-3-carboxylate (beta-CCE) on behavioral, hormonal, and neurochemical responses in infant rhesus monkeys exposed to fearful situations. Our paradigm elicits three distinct adaptive patterns of defensive behavior. From previous work, we hypothesized

Effect of exposure of primary cultured cerebral cortical neurons to ethyl beta-carboline-3-carboxylate (beta-CCE) on the function of benzodiazepine receptors was studied. Exposure of neurons to beta-CCE (0.1-10 microM) decreased the binding of [3H]flunitrazepam to extensively washed membrane fractions in a

This study examined changes in ventilation produced by negative gamma-aminobutyric acid(A) (GABA(A)) modulators in rhesus monkeys. The effects of Ro 15-4513, beta-CCE and beta-CCM were examined in four rhesus monkeys breathing air or 5% CO2 in air. When monkeys breathed
