While the traditional monoaminergic hypothesis has largely fallen short in its ability to provide a complete picture of major depressive disorder, emerging preclinical and clinical findings suggest that dysfunctional glutamatergic neurotransmission may underlie the pathophysiology of both major depressive disorder and bipolar depression. The neurotransmission mediated by the excitatory amino acids (EAA) glutamate (GLU) and aspartate is of interest to the pharmacotherapy of psychosis due to its role in neurodevelopment and neurotoxicity, its complex interactions with dopaminergic and other neurotransmitter systems and its pivotal importance in recent models of schizophrenia. Drugs acting on the excitatory glutamatergic system have so far not been tested with TMS-EEG measures, although glutamatergic neurotransmission plays a fundamental role in the excitation Glutamatergic neurotransmission: due to the risk of excitotoxic damage in the wake of excessive glutamatergic stimulation, precise physiological control of glutamate must be maintained in the mammalian CNS. Glutamine (Gln) is converted to glutamate (Glu) by glutaminase [though glutamate may also be derived from the TCA cycle (not shown)]. Overview of Synaptic Neurotransmission: Glutamatergic Excitation Glutamate receptors (GluRs), the major excitatory receptor in the brain, are characterized as ionotropic or metabotropic.

METHOD: CSF was obtained from 18 matched comparison subjects and from 18 patients with alcohol dependence 1 week and 1 month after cessation of ethanol ingestion. The results demonstrate a key role of the D 4 receptor in the modulation of corticostriatal glutamatergic neurotransmission. Furthermore, these data imply that enhanced D 4 receptor–mediated Glutamatergic neurotransmission in thalamocortical system may play an important role in modulating sensory perception and consciousness. Our results showed that ketamine (30 μM–1000 μM) decreased the amplitude of sEPSCs and higher concentration of ketamine (300 μM and 1000 μM) decreased the frequency of sEPSCs. VMH glutamatergic neurotransmission has been shown to be important for enhancing counterregulatory responses to hypoglycemia . However, the postsynaptic receptors that mediate these stimulatory effects and how RH affects glutamate neurotransmission have not been investigated in detail.

This book contains detailed discussions on tracing neuronal pathways, functional or spectroscopic imaging, optogenetic or pharmacological tools, and extracellular neurochemistry in experimental clinical models. The chapters cover topics such as: identification of Therapies that target glutamatergic neurotransmission are available, but many have met with difficulty because of untoward adverse effects. Better understanding of this system has generated novel therapeutic targets that directly and indirectly modulate glutamatergic signaling. 2001-01-01 · Glutamatergic neurotransmission may be altered at several different steps: the content (expression, synthesis and/or degradation) of the main proteins involved in glutamatergic neurotransmission (e.g. the different types of glutamate receptors or transporters); the regulation of the spatial location of the receptors and transporters; the function of the receptors and transporters, which is A thorough dose-response study using microdialysis in conscious rats indicated that low doses of ketamine (10, 20, and 30 mg/kg) increase glutamate outflow in the PFC, suggesting that at these doses ketamine may increase glutamatergic neurotransmission in the PFC at non-NMDA glutamate receptors. As the static concentration of Glu measured by MRS reflects the total Glu pool size, which is involved in varied functions (e.g.

Se hela listan på en.wikipedia.org Within this medication development framework, the modulation of glutamatergic neurotransmission has become the focus of intense research. Glutamate (GLU)-mediated neuronal processes are critical throughout the brain and glutamatergic neurotransmission dysfunctions have been hypothesised to play a crucial role in schizophrenia pathophysiology. In view of (i) the close spatio-temporal synergy exhibited between excitatory, inhibitory and modulatory neurotransmitter systems; (ii) the crucial role played by glutamate (Glu) in tonic/phasic dopaminergic signalling; and (iii) the interdependent metabolic relationship exhibited between Glu and GABA via glutamine (Gln); we postulated that glutamatergic signalling is related to the pathophysiology of Gilles de la Tourette syndrome. Interestingly, females with ablation of vGluT2 in Kiss1 neurons appeared to exhibit a normal ovulatory cycle, an indication that glutamatergic neurotransmission from Kiss1 neurons may not be necessary to support reproductive function. This volume presents techniques and recent developments in biochemical approaches to study glutamatergic neurotransmission.
