background: bone marrow stromal stem cells (bmsc) are appropriate source of multipotent stem cells that are ideally suited for use in various cell-based therapies. it can be differentiated into neuronal-like cells under appropriate conditions. this study examined the effectiveness of co-stimulation of creatine and retinoic acid in increasing the differentiation of bmsc into gabaergic neuron-lik...
Background: Neurotransmitter release is an essential link in cell communication of the nervous system. Many investigations have focused on gamma amino butyric acid (GABA)-ergic neurotransmission, because it has been implicated in the pathophysiology of several central nervous system disorders. To bypass complications related to homo- and heterosynaptic modulation and to avoid indirect interpret...
Background: Hypertension is considered an independent risk factor for cardiovascular mortality in diabetic patients. The present study was designed to determine the role of gamma amino butyric acid B (GABAB) receptor and L-arginine (L-Arg) in GABA-induced vasorelaxation in normal and streptozotocin-induced diabetic rat vessels. Methods: Diabetes was induced by a single i.p. injection of strepto...
In several countries, 3,4-methylenedioxymethamphetamine (MDMA) is currently the most abundant psychoactive recreational drug. MDMA induces numerous neuropsychiatric behaviors, serotonergic neuron degeneration, programmed death of cultured cells, hyperthermia and occasional fatality. Using gene expression analysis in MDMA-treated mice, we identified changes in gamma-amino butyric acid (GABA) tra...
Glutamic acid decarboxylase (GAD) is an enzyme which converts the glutamic acid to the neurotransmitter gamma-amino butyric acid (GABA). GABA is an inhibitory neurotransmitter that inhibits or weakens the neuronal stimulations. Presynaptic GABAergic neurons in the central neurons system (CNS) and the cells in the islets of Langerhans in the pancreas generate GAD. There are two isoforms of GAD n...

It can be differentiated into neuronal-like cells under appropriate conditions. This study examined the effectiveness of co-stimulation of creatine and retinoic acid in increasing the differentiation of BMSC into GABAergic neuron-lik...
Pulmonary adenocarcinoma (PAC) is the leading type of lung cancer in smokers and non-smokers that arises in most cases from small airway epithelial cells. PAC has a high mortality due to its aggressive behavior and resistance to cancer therapeutics. We have shown previously that the proliferation of human PAC cells NCI-H322 and immortalized human small airway epithelial cells HPL1D is stimulate...
Objective(s) The aim of this study was to evaluate the effects of dexamethasone on striatal dopaminergic, glutamatergic and gamma amino butyric acid (GABA) ergic neurotransmission in normal and parkinsonian rats. Materials and Methods Dexamethasone (0.15, 0.30, 0.60 and 0.8 mg/kg) was administered to normal or parkinsonian rats (i.p.) followed by the analysis of the striatal neurotransmitter...

Inhibitory sculpting of afferent signals in the thalamus is exerted by two types of neurons using gamma-amino butyric acid (GABA) as neurotransmitter. Of them, local-circuit neurons exert their functions via two outputs: axons and presynaptic dendrites. In this issue of Neuron, Govindaiah and Cox reveal that synaptic activation of metabotropic glutamate receptors selectively increases the outpu...
