GABA-induced uncoupling of GABA/benzodiazepine site interactions is mediated by increased GABAA receptor internalization and associated with a change in subunit composition
(Elsevier, 2014-01)
Persistent activation of GABAA receptors triggers compensatory changes in receptor function that are relevant to physiological, pathological and pharmacological conditions. Chronic treatment of cultured neurons with GABA ...
GABAergic mediation of stress-induced secretion of corticosterone and oxytocin, but not prolactin, by the hypothalamic paraventricular nucleus
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The hypothalamus-pituitary-adrenal axis (HPA) participates in mediating the response to stressful stimuli. Within the HPA, neurons in the medial parvocellular region of paraventricular nucleus (PVN) of the hypothalamus ...
GABA-induced uncoupling of GABA/benzodiazepine site interactions is associated with increased phosphorylation of the GABAA receptor
(Wiley, 2014-08)
The use-dependent regulation of the GABAA receptor occurs under physiological, pathological, and pharmacological conditions. Tolerance induced by prolonged administration of benzodiazepines is associated with changes in ...
GABA released from cultured cortical neurons influences the modulation of t-[35S]butylbicyclophosphorothionate binding at the GABAA receptor: Effects of thymol
(Elsevier Science, 2008-12)
Thymol is a monoterpene that specifically interacts with synaptic neural functions in neuronal GABA-operated Cl- channels. Here we explore the effects of thymol, and propofol as positive control, on t-[35S]butylbicycloph ...
Marlin-1 and conventional kinesin link GABA(B) receptors to the cytoskeleton and regulate receptor transport
(2007)
The cytoskeleton and cytoskeletal motors play a fundamental role in neurotransmitter receptor trafficking, but proteins that link GABA(B) receptors (GABA(B)Rs) to the cytoskeleton have not been described. We recently ...
Neurotransmitter GABA Activates Muscle but not a7 Nicotinic Receptors
(American Society For Pharmacology And Experimental Therapeutics, 2015-03)
Cys-loop receptors are neurotransmitter-activated ion channels involved in synaptic and extrasynaptic transmission in the brain and are also present in non-neuronal cells. As GABAA and nicotinic receptors (nAChR) belong ...
Benzodiazepine modulation of homomeric GABAAρ1 receptors: Differential effects of diazepam and 40´-chlorodiazepam
(Elsevier, 2014-09-22)
GABAA receptors (GABAARs) are ligand-gated ion channels that mediate inhibitory neurotransmission in the central nervous system (CNS). They are members of the Cys-loop receptor family and display marked structural and ...
GABAB receptors in neuroendocrine regulation
(Springer, 2008-09)
Gamma-amino butyric acid (GABA), in addition to being a metabolic intermediate and the main inhibitory neurotransmitter in the synaptic cleft, is postulated as a neurohormone, a paracrine signaling molecule, and a trophic ...
Effect of the GABA(B) agonist baclofen on dipyrone-induced delayed gastric emptying in rats
(Assoc Bras Divulg CientificaSao PauloBrasil, 2005)
Involvement of GABA(A)-benzodiazepine receptor in the anxiolytic effect induced by hexanic fraction of Rubus brasiliensis
(Elsevier B.V., 1998-06-01)
To investigate the ability of hexanic ethanolic fraction of Rubus brasiliensis Martius (Roseceae), to induce anxiolytic effect and also the possible involvement of the GABA(A)-benzodiazepine receptor complex, male Wistar ...
