Introduction: Estradiol is a neuroactive steroid, which is found in several brain areas such as locus coeruleus (LC). Estradiol modulates nociception by binding to its receptors and also by allosteric interaction with other membranebound receptors like glutamate and GABAA receptors. LC is involved in noradrenergic descending pain modulation. Methods: In order to study the effect of 17β-estra...

introduction: neuropathic pain can be very difficult to treat and it is one of the important medical challenging about pain treatments. muscimol as a new agonist of gamma-aminobutyric acid receptor type a (gaba a ) have been introduced for pain management. thus, the present study was performed to evaluate the pain alleviating effect of intrathecal injection of different doses of muscimol as gab...
introduction: 17&beta-estradiol; modulates nociception by binding to the estrogenic receptors and also by allosteric interaction with other membrane-bound receptors like glutamate and gabaa receptors. in addition to its autonomic functions, paragigantocellularis lateralis (lpgi) is involved in the pain modulation, too. the aim of the current study was to investigate the involvement of the membr...
Autism spectrum disorder (ASD) may arise from increased ratio of excitatory to inhibitory neurotransmission in the brain. Many pharmacological treatments have been tested in ASD, but only limited success has been achieved. Here we report that BTBR T(+)Itpr3(tf)/J (BTBR) mice, a model of idiopathic autism, have reduced spontaneous GABAergic neurotransmission. Treatment with low nonsedating/nonan...
Using flow cytometry in conjunction with a voltage-sensitive fluorescent indicator dye (oxonol), we have identified and separated embryonic hippocampal cells according to the sensitivity of their functionally expressed GABAA receptors to zolpidem. Immunocytochemical and RT-PCR analysis of sorted zolpidem-sensitive (ZS) and zolpidem-insensitive (ZI) subpopulations identified ZS cells as postmito...
Whole-cell and cell-attached patch-clamp recordings were used to investigate the nature of GABAA receptor-mediated inhibition in the adult rat dentate gyrus in standard 400-microns-thick horizontal slices. In the presence of the glutamate receptor antagonists D-2-amino-5-phosphonovaleric acid and 6-cyano-7-nitroquinoxaline-2,3-dione, whole-cell voltage-clamp experiments with chloride-filled ele...
Approximately one-third of human genetic diseases are caused by premature translation-termination codon (PTC)-generating mutations. These mutations in sodium channel and GABAA receptor genes have been associated with idiopathic generalized epilepsies, but the cellular consequences of the PTCs on the mutant channel subunit biogenesis and function are unknown. The PTCs could result in translation...
UNLABELLED The ventrolateral periaqueductal gray (vlPAG) is a key structure in the descending pain modulatory circuit. Activation of the circuit occurs via disinhibition of GABAergic inputs onto vlPAG output neurons. In these studies, we tested the hypothesis that GABAergic inhibition is increased during persistent inflammation, dampening activation of the descending circuit from the vlPAG. Our...
Background: Estradiol and progesterone as well as hippocampal GABAA receptors are believed to play a role in the modulation of pain. The aim of present study was to investigate the effect of intrahippocampal injections of GABAA receptor agonist (muscimol) and GABAA receptor antagonist (picrotoxin) on pain sensitivity during estrous cycle. Methods: Pain sensitivity was evaluated in rats ...
