A correlation between changes in gamma-aminobutyric acid metabolism and seizures induced by antivitamin B6. (1/617)

The effects of DL-penicillamine (DL-PeA), hydrazine and toxopyrimidine (TXP, 2-methyl-6-amino-5-hydroxymethylpyrimidine) on gamma-aminobutyric acid (GABA) metabolism in mouse brain were studied. All these compounds inhibited the activity of glutamate decarboxylase [EC 4.1.1.15] (GAD) and slightly inhibited that of 4-aminobutyrate: 2-oxoglutarate aminotransferase [EC 2.6.1.19] (GABA-T). In contrast, very different effects were observed on GABA levels; hydrazine caused a marked increase, DL-PeA had no effect, and TXP caused a slight decrease in the content of the amino acid. These results could be described by an equation which related the excitable state to changes in the flux of the GABA bypass. Since the values obtained from the equation clearly reflect the seizure activity, it is suggested that the decreased GABA flux might be a cause of convulsions induced by these drugs.  (+info)

Mechanisms involved in the metabotropic glutamate receptor-enhancement of NMDA-mediated motoneurone responses in frog spinal cord. (2/617)

1. The metabotropic glutamate receptor (mGluR) agonist trans-(+/-)-1-amino-1,3-cyclopentanedicarboxylic acid (trans-ACPD) (10-100 microM) depolarized isolated frog spinal cord motoneurones, a process sensitive to kynurenate (1.0 mM) and tetrodotoxin (TTX) (0.783 microM). 2. In the presence of NMDA open channel blockers [Mg2+; (+)-5-methyl-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5,10-imine hydrogen maleate (MK801); 3,5-dimethyl-1-adamantanamine hydrochloride (memantine)] and TTX, trans-ACPD significantly potentiated NMDA-induced motoneurone depolarizations, but not alpha-amino-3-hydroxy-5-methylisoxazole-4-proprionate (AMPA)- or kainate-induced depolarizations. 3. NMDA potentiation was blocked by (RS)-alpha-methyl-4-carboxyphenylglycine (MCPG) (240 microM), but not by alpha-methyl-(2S,3S,4S)-alpha-(carboxycyclopropyl)-glycine (MCCG) (290 microM) or by alpha-methyl-(S)-2-amino-4-phosphonobutyrate (L-MAP4) (250 microM), and was mimicked by 3,5-dihydroxyphenylglycine (DHPG) (30 microM), but not by L(+)-2-amino-4-phosphonobutyrate (L-AP4) (100 microM). Therefore, trans-ACPD's facilitatory effects appear to involve group I mGluRs. 4. Potentiation was prevented by the G-protein decoupling agent pertussis toxin (3-6 ng ml(-1), 36 h preincubation). The protein kinase C inhibitors staurosporine (2.0 microM) and N-(2-aminoethyl)-5-isoquinolinesulphonamide HCI (H9) (77 microM) did not significantly reduce enhanced NMDA responses. Protein kinase C activation with phorbol-12-myristate 13-acetate (5.0 microM) had no effect. 5. Intracellular Ca2+ depletion with thapsigargin (0.1 microM) (which inhibits Ca2+/ATPase), 1,2-bis(O-aminophenoxy)ethane-N,N,N',N'-tetracetic acid acetyl methyl ester (BAPTA-AM) (50 microM) (which buffers elevations of [Ca2+]i), and bathing spinal cords in nominally Ca2+-free medium all reduced trans-ACPD's effects. 6. The calmodulin antagonists N-(6-aminohexyl)-5-chloro-1-naphthalenesulphonamide (W7) (100 microM) and chlorpromazine (100 microM) diminished the potentiation. 7. In summary, group I mGluRs selectively facilitate NMDA-depolarization of frog motoneurones via a G-protein, a rise in [Ca2+]i from the presumed generation of phosphoinositides, binding of Ca2+ to calmodulin, and lessening of the Mg2+-produced channel block of the NMDA receptor.  (+info)

An inhibitor of exported Mycobacterium tuberculosis glutamine synthetase selectively blocks the growth of pathogenic mycobacteria in axenic culture and in human monocytes: extracellular proteins as potential novel drug targets. (3/617)

Mycobacterium tuberculosis and other pathogenic mycobacteria export abundant quantities of proteins into their extracellular milieu when growing either axenically or within phagosomes of host cells. One major extracellular protein, the enzyme glutamine synthetase, is of particular interest because of its link to pathogenicity. Pathogenic mycobacteria, but not nonpathogenic mycobacteria, export large amounts of this protein. Interestingly, export of the enzyme is associated with the presence of a poly-L-glutamate/glutamine structure in the mycobacterial cell wall. In this study, we investigated the influence of glutamine synthetase inhibitors on the growth of pathogenic and nonpathogenic mycobacteria and on the poly-L-glutamate/glutamine cell wall structure. The inhibitor L-methionine-S-sulfoximine rapidly inactivated purified M. tuberculosis glutamine synthetase, which was 100-fold more sensitive to this inhibitor than a representative mammalian glutamine synthetase. Added to cultures of pathogenic mycobacteria, L-methionine- S-sulfoximine rapidly inhibited extracellular glutamine synthetase in a concentration-dependent manner but had only a minimal effect on cellular glutamine synthetase, a finding consistent with failure of the drug to cross the mycobacterial cell wall. Remarkably, the inhibitor selectively blocked the growth of pathogenic mycobacteria, all of which release glutamine synthetase extracellularly, but had no effect on nonpathogenic mycobacteria or nonmycobacterial microorganisms, none of which release glutamine synthetase extracellularly. The inhibitor was also bacteriostatic for M. tuberculosis in human mononuclear phagocytes (THP-1 cells), the pathogen's primary host cells. Paralleling and perhaps underlying its bacteriostatic effect, the inhibitor markedly reduced the amount of poly-L-glutamate/glutamine cell wall structure in M. tuberculosis. Although it is possible that glutamine synthetase inhibitors interact with additional extracellular proteins or structures, our findings support the concept that extracellular proteins of M. tuberculosis and other pathogenic mycobacteria are worthy targets for new antibiotics. Such proteins constitute readily accessible targets of these relatively impermeable organisms, which are rapidly developing resistance to conventional antibiotics.  (+info)

Retinal ganglion cell response properties in the transcorneal electrically evoked response of the visual system. (4/617)

To identify the retinal origin of a cortical evoked potential elicited by transcorneal electrical stimulation of the visual system (EER), the response properties of retinal ganglion cells (RGCs) of cats to transcorneal electrical stimuli were studied. The discharge latency of RGCs to transcorneal stimulation had two peaks with a high temporal resolution. The latency of early components of the EER is associated with the discharge latency of RGCs. Some RGCs showed prominent oscillatory discharges after transcorneal stimulation. Discharges of ON-bipolar cells responding to transcorneal stimulation were significantly inhibited by intravitreal injection of DL-2-amino-4-phosphonobutyrate (APB), which blocks the ON-pathway. These findings indicate that the EER has far-field potentials that might relate to oscillatory discharges of RGCs, and that ON bipolar cells and their related synaptic sites are involved in transcorneal electrical stimuli. The far-field potentials of the EER may have clinical applications, similar to those of somatosensoric evoked potentials and auditory brain stem potentials.  (+info)

Analysis of pharmacologically isolated components of the ERG. (5/617)

An harmonic analysis was applied to the electroretinogram (ERG) measured in intact cat eyes in control conditions and after pharmacological isolation of the components attributed to photoreceptors (PIII) and bipolar neurons (PII). The frequency response curves obtained in various conditions showed that the bandwidth of the PII component extends over a range of stimulus frequencies higher than the bandwidth of PIII. The enhancement of the PII response to stimuli of high temporal frequency suggests the presence of a frequency dependent gain control located either pre- and/or post-synaptically in the transmission line between the phototransductive cascade and bipolar neurons. A possible role of these processes is to enhance relevant visual information whilst selectively attenuating low frequency signals originating in the transductive cascade.  (+info)

NPY inhibits glutamatergic excitation in the epileptic human dentate gyrus. (6/617)

Neuropeptide Y (NPY) has been shown to depress hyperexcitable activity that has been acutely induced in the normal rat brain. To test the hypothesis that NPY can also reduce excitability in the chronically epileptic human brain, we recorded intracellularly from dentate granule cells in hippocampal slices from patients with hippocampal seizure onset. NPY had a potent and long-lasting inhibitory action on perforant path-evoked excitatory responses. In comparison, the group 3 metabotropic glutamate receptor agonist L-2-amino-4-phosphonobutyric acid (L-AP4) evoked a mild and transient decrease. NPY-containing axons were found throughout the hippocampus, and in many epileptic patients were reorganized, particularly in the dentate molecular layer. NPY may therefore play a beneficial role in reducing granule cell excitability in chronically epileptic human tissue, and subsequently limit seizure severity.  (+info)

A novel domain of the inhibitory glycine receptor determining antagonist efficacies: further evidence for partial agonism resulting from self-inhibition. (7/617)

Different amino side chains in the N-terminal extracellular region of the inhibitory glycine receptor (GlyR) have been shown to be crucial for ligand recognition. Here we describe a novel domain of the GlyRalpha1 subunit that constitutes an important determinant of antagonist activity. The antagonists strychnine, nipecotic acid, and isobutyric acid displayed reduced potencies at recombinant GlyRs formed from alpha1 subunits, in which lysine 104, phenylalanine 108, or threonine 112 were replaced by alanine. Agonist affinities, in contrast, were slightly increased at these mutant receptors. Taurine and beta-aminoisobutyric acid, which are partial agonists at the wild-type GlyR, behaved as full agonists at the mutant GlyRs and failed to inhibit glycine-induced currents. This is consistent with apolar residues at positions 104, 108, and 112 of the alpha1 subunit reducing the antagonistic, but not the agonistic, binding of beta-amino acids. Our data support a model in which the partial agonism of beta-amino acids results from their self-inhibitory activity.  (+info)

Role of Ngamma-acetyldiaminobutyrate as an enzyme stabilizer and an intermediate in the biosynthesis of hydroxyectoine. (8/617)

Strain CHR63 is a salt-sensitive mutant of the moderately halophilic wild-type strain Halomonas elongata DSM 3043 that is affected in the ectoine synthase gene (ectC). This strain accumulates large amounts of Ngamma-acetyldiaminobutyrate (NADA), the precursor of ectoine (D. Canovas, C. Vargas, F. Iglesias-Guerra, L. N. Csonka, D. Rhodes, A. Ventosa, and J. J. Nieto, J. Biol. Chem. 272:25794-25801, 1997). Hydroxyectoine, ectoine, and glucosylglycerate were also identified by nuclear magnetic resonance (NMR) as cytoplasmic organic solutes in this mutant. Accumulation of NADA, hydroxyectoine, and ectoine was osmoregulated, whereas the levels of glucosylglycerate decreased at higher salinities. The effect of the growth stage on the accumulation of solutes was also investigated. NADA was purified from strain CHR63 and was shown to protect the thermolabile enzyme rabbit muscle lactate dehydrogenase against thermal inactivation. The stabilizing effect of NADA was greater than the stabilizing effect of ectoine or potassium diaminobutyrate. A (1)H NMR analysis of the solutes accumulated by the wild-type strain and mutants CHR62 (ectA::Tn1732) and CHR63 (ectC::Tn1732) indicated that H. elongata can synthesize hydroxyectoine by two different pathways-directly from ectoine or via an alternative pathway that converts NADA into hydroxyectoine without the involvement of ectoine.  (+info)

The canola line T45 was genetically engineered to express tolerance to glufosinate ammonium, the active ingredient in phosphinothricin herbicides (Basta®, Rely®, Finale®, and Liberty®). Glufosinate chemically resembles the amino acid glutamate and acts to inhibit an enzyme, called glutamine synthetase, which is involved in the synthesis of glutamine. Essentially, glufosinate acts enough like glutamate, the molecule used by glutamine synthetase to make glutamine, that it blocks the enzymes usual activity. Glutamine synthetase is also involved in ammonia detoxification. The action of glufosinate results in reduced glutamine levels and a corresponding increase in concentrations of ammonia in plant tissues, leading to cell membrane disruption and cessation of photosynthesis resulting in plant withering and death ...

AU - Orbach, Joseph. PY - 1980/1/1. Y1 - 1980/1/1. N2 - The sites of action of γ-aminobutyric acid (GABA) were examined in preparations of the distal colon and ileum of guinea pigs. GABA caused transient relaxations of the longitudinal and circular muscle of the colon and transient constractions followed by relaxation of the muscle of the ileum. The responses of both parts of the intestine were antagonized by tetrodotoxin and by bicuculline. Nerve-free preparations of the longitudinal muscle of the ileum were not affected by GABA, even in concentrations up to 10−4 g/ml. There was a marked tachyphylaxis of the responses to GABA. Relaxations in response to GABA were not affected by pentolinium or by a combination of phetolamine and propranolol. Contractions in response to GABA were blocked by hyoscine. Neither ...
1. γ-Aminobutyric acid (GABA) immunoreactivity is demonstrated by the indirect immunofluorescence technique in a small population of retinal neurons cultured from human fetuses. 2. Positive staining was restricted to a few cells and could be observed as soon as the cells became attached to the substrate (within 5 hr). It is therefore concluded that the GABA-positive cells are determined prenatally. 3. The GABA-positive cells grow processes during development in culture and remain constant in numbers. These cells have a different morphology from either GFAP-positive cells or serotinin-accumulating cells. 4. It is suggested that the GABA-positive cells in culture are probably amacrine neurones. 5. Cultures of human retinal dissociates may therefore provide an alternative means of studying specific cell types should a constant supply of living human retinas be difficult to obtain. γ-Aminobutyric acid (GABA) immunoreactivity is demonstrated by the indirect immunofluorescence technique in a small

Koerner and Cotman (1981) initially described that the diacidic amino acid analog l-2-amino-4-phosphonobutyric acid (l-AP4) selectively suppressed glutamate excitations by a presynaptic mechanism in the lateral perforant pathway of the hippocampus. This inhibitory activity of l-AP4 on glutamate excitations was also observed in other preparations, including the mossy fiber synapse, lateral olfactory tract, and spinal cord (seeThomsen, 1997). Until the 1990s, presynaptic inhibition induced by l-AP4 was ascribed to a relatively nebulous l-AP4 receptor. However, with the cloning of the group III mGlu receptors, which Nakanishi (1992) defined by their sensitivity to l-AP4, it was recognized that certain group III mGlu subtypes might be responsible forl-AP4-induced suppression of glutamate release. Current data suggest a role for mGlu7, mGlu8, and possibly mGlu4 as candidates for these presynaptic effects of l-AP4 in the brain (seeThomsen, 1997).. In general, when compared with mGlu7 or mGlu2/3 ...

One of the most commonly used methods for in vivo MRS detection of γ-aminobutyric acid (GABA) is the MEGA-point-resolved spectroscopy (MEGA-PRESS) technique. However, accurate quantification of GABA using MEGA-PRESS is complicated by spectral co-editing of macromolecular resonances. In this article, a new pulse sequence is presented which enables GABA editing at 3T with the removal of macromolecule contamination. This sequence combines the conventional MEGA editing scheme with the SPECIAL localisation technique, and is therefore named MEGA-SPECIAL. Simulations and phantom experiments indicate that this new approach provides improved GABA editing efficiency relative to MEGA-PRESS, and in vivo results demonstrate effective removal of macromolecule contamination. In a study of the occipital lobe of five healthy volunteers, the macromolecule-corrected GABA/creatine ratio was found to be 0.093 ± 0.007 (mean ± standard deviation), whereas prior to macromolecule correction, the ratio was found to be 0.173
We show that expression of B. subtilis threonine deaminase, combined with expression of a mutated form of E. coli glutamate dehydrogenase leads to the production of 0.40 ± 0.02 mg/L of (S)-2-aminobutyric acid in shake flask-grown S. cerevisiae cells. The higher production in E. coli achieved by Zhang and co-workers [26] is perhaps due to the special properties of the E. coli strain employed, which can produce 8 g/L l-threonine from 30 g/L glucose. Nevertheless, we rationalize that yeast is indeed a superior production host for (S)-2-aminobutanol production, as it displays higher robustness and considerable tolerance against harsh fermentation conditions. Yeast is also more resistant towards exposure to (S)-2-aminobutanol (Additional file 1: Figure S4). Moreover, the fermentation of yeasts is easily implemented into existing ethanol productions plants, and there are no issues with phage contamination. S. cerevisiae is classified as GRAS (generally regarded as safe) organism; thereby further ...

Using the above system, an OGD dose-response curve was generated first. The culture medium was changed to an exposure medium (glucose-free 37°C Hanks balanced salt solution; Invitrogen Corp.). Culture plates were then placed in a thermoregulated chamber (37°C). The gas phase was altered to 95% N2-5% CO2flowing into the incubated chamber at 10 l/min. Pilot studies were performed which determined that this flow rate caused a reduction of the oxygen concentration to less than 5% within 8 min, after which flow was reduced to 1 l/min for the balance of the exposure interval. Oxygen concentration in the effluent gas was continuously monitored with a medical gas analyzer to assure it remained under 5% for the balance of the exposure interval.

γ‐Aminobutyric acid (GABA), the principal inhibitory neurotransmitter in the brain, signals through ionotropic (GABAA/C) and metabotropic (GABAB) receptor systems
Alzheimers disease (AD) is characterized by the transition of amyloid-β (Aβ) monomers into toxic oligomers and plaques. Given that Aβ abnormality typically precedes the development of clinical symptoms, an agent capable of disaggregating existing Aβ aggregates may be advantageous. Here we report that a small molecule, 4-(2-hydroxyethyl)-1-piperazinepropanesulphonic acid (EPPS), binds to Aβ aggregates and converts them into monomers. The oral administration of EPPS substantially reduces hippocampus-dependent behavioural deficits, brain Aβ oligomer and plaque deposits, glial γ-aminobutyric acid (GABA) release and brain inflammation in an Aβ-overexpressing, APP/PS1 transgenic mouse model when initiated after the development of severe AD-like phenotypes ...

N2 - A common function of group III metabotropic glutamate receptors (mGluRs) located at the presynaptic site of a glutamatergic synapse is synaptic depression. Here, we studied synaptic depression mediated by group III mGluR activation at Schaffer collateral-CA1 (SC-CA1) synapses and associational-commissural-CA3 (AC-CA3) synapses by recording field excitatory postsynaptic potentials in the in vitro brain slice preparation. In order to gauge the impact of synaptic depression in chronically epileptic tissue, we compared rats after pilocarpine-induced status epilepticus (post-SE) with control animals. We observed that synaptic transmission at control AC-CA3 ...
Current therapies for Parkinsons disease are able to ameliorate the symptoms in the early stages, however as the disease progresses, they become less effective and patients often develop debilitating side effects. There is currently a significant unmet need for disease modifying or neuroprotective drugs to slow the rate of disease progression and provide long-term symptomatic relief. Novel therapeutics that can provide symptomatic relief whilst attenuating the ongoing neurodegeneration are therefore sought. The targeting of metabotropic glutamate (mGlu) receptors has become a therapeutic focus in recent years. The group III mGlu receptors are the focus of this thesis as they currently hold the most therapeutic promise, with evidence suggesting activation of these receptors not only modulates aberrant neurotransmission in the basal ganglia to provide symptom relief, but also provides neuroprotective effects in the nigrostriatal system through a variety of mechanisms. Recent advances in the ...

AU - Moenter, Suzanne M.. PY - 2002/12/1. Y1 - 2002/12/1. N2 - γ,-Aminobutyric acid (GABA), acting through GABAA receptors (GABAAR), is hypothesized to suppress reproduction by inhibiting GnRH secretion, but GABA actions directly on GnRH neurons are not well established. In green fluorescent protein-identified adult mouse GnRH neurons in brain slices, gramicidin-perforated-patch-clamp experiments revealed the reversal potential (EGABA) for current through GABAARs was depolarized relative to the resting potential. Furthermore, rapid GABA application elicited action potentials in GnRH neurons but not controls. The consequence of GABAAR activation depends on intracellular chloride levels, which are maintained by homeostatic mechanisms. Membrane proteins that typically extrude chloride (KCC-2 cotransporter, CLC-2 ...
Glufosinate is the active ingredient that inhibits plant growth in herbicides that LibertyLink plants are resistant to. These herbicides can come in a variety of forms, including bialaphos, a tripeptide containing two alanine residues and glufosinate. In the case of bialaphos, the peptide is cleaved to produce the active glufosinate.. Glufosinate is very similar in chemical structure to the amino acid glutamate. Because of this structural similarity, glufosinate is able to act as an inhibitor for the enzyme glutamine synthetase, for which glutamate is a substrate. The inhibition of glutamine synthase (GS) results in disruption of the glycolate pathway. Metabolic flux through the pathway is reduced and intracellular levels of pathway intermediates accumulate. One of these intermediates, glyoxylate, is a a strong inhibitor of the key photosynthetic enzyme ribulose bisphosphate carboxylase. Without the activity of this enzyme, plants are unable to fix carbon and rapidly die.. Glufosinate is an ...
Liberty herbicide (glufosinate ammonium) does not kill Pioneer Hi-Breds genetically engineered (GE) Liberty Link corn, even though it is taken up and translocated throughout the plant, because the corn inactivates the herbicide. Genes engineered into the corn produce enzymes in every cell of the corn plant that change glufosinate ammonium into N-acetyl-L-glufosinate, or NAG. When you eat the corn, though, you are also eating NAG that accumulated in the crop with each herbicide application. Some of that NAG may be transformed back into the toxic herbicide in your gut, possibly by bacteria. Two studies with rats showed conversion rates of 1% and 10% respectively, while a study with goats showed conversion of more than one-third. The revived herbicide may travel to kidneys, liver, muscle, fat and milk, where it may be toxic ...
Martin LJ, Oh GH, Orser BA. (2009) Anesthesiology. 111(5):1025-35.. Abstract. BACKGROUND: The memory-blocking properties of general anesthetics have recently received considerable attention because of concerns related to intraoperative awareness and postoperative cognitive dysfunction. The goal of this study was to identify the mechanisms by which γ-aminobutyric acid subtype A receptors that contain the α5 subunit (α5GABAARs) induce memory-blockade by etomidate and a pharmacologic strategy to reverse this impairment.. METHODS: The effects of etomidate and the α5GABAAR-preferring inverse agonist L-655,708 on the plasticity of glutamatergic excitatory transmission in hippocampal slices and behavioral memory for spatial navigational and fear-associated memory tasks were studied in wild-type and null mutant mice for the gene that encodes the α5 subunit (Gabra5-/- mice). Long-term potentiation of field excitatory postsynaptic potentials was induced in CA1 pyramidal neurons following ...
Delirium occurs in 60-80% of ventilated Intensive Care Unit (ICU) patients and is independently associated with prolonged hospital stay, higher cost, a 3-fold increased risk of dying by six months and ongoing neuropsychological dysfunction. Hypothesis: Based on our preliminary work, we hypothesize that standard use of GABA agonist sedatives such as lorazepam and propofol may contribute to ICU delirium and its attendant untoward clinical outcomes. An alternative sedation strategy targeting alpha2 receptors and sparing GABA receptors (dexmedetomidine) might reduce delirium, provide adequate sedation, reduce analgesic requirement, and concurrently improve cognitive performance.. Long-term objective: To standardize and compare different strategies of sedation and analgesia for ventilated ICU patients in order to optimize their clinical outcomes focusing on delirium and the long-term neuropsychological dysfunction of ICU survivors.. Specific Aims:. ...

RESULTS: The GABA signalling system was compromised in islets from type 2 diabetic individuals, where the expression of the genes encoding the α1, α2, β2 and β3 GABA(A) channel subunits was downregulated. GABA originating within the islets evoked tonic currents in the cells. The currents were enhanced by pentobarbital and inhibited by the GABA(A) receptor antagonist, SR95531. The effects of SR95531 on hormone release revealed that activation of GABA(A) channels (GABA(A) receptors) decreased both insulin and glucagon secretion. The GABA(B) receptor antagonist, CPG55845, increased insulin release in islets (16.7 mmol/l glucose) from normoglycaemic and type 2 diabetic individuals ...

Are you stressed? Having trouble sleeping? Suffering from anxiety? You may, like 99.32% of all other Americans, be deficient in magnesium. Not to worry! Fresh off the slow boat from Australia, GABAMAG is here to help.. Among a host of other advantages, magnesium has a calming effect on your bodys nervous system and relaxes the muscles, which in turn will help you to fall asleep easier. A deficiency of magnesium is also sometimes responsible for the nervousness that prevents sleep as well as restless legs syndrome. Magnesium may also improve the length and quality of slow wave sleep. Additionally magnesium binds to and activates GABA receptors. GABA is short for gamma aminobutyric acid, which is your most major relaxing neurotransmitter (brain chemical). Normalisation of brain GABA levels leads to a reduction in stress, anxiety, nervousness, depression and an improvement in insomnia resulting in a more restful nights sleep. ...

The synaptic receptors of ON bipolar neurons are selectively activated by 2-amino-4-phosphonobutyrate, a glutamate analogue. This agent uniquely distinguishes these receptors from other types of excitatory amino acid receptors found in the retina. Various glutamate and aspartate analogues were used to assess the structure-activity characteristics of this receptor. The results suggest that it represents one class of glutamate receptor which can be distinguished by its preferential activation by acidic amino acid analogues that match the extended conformation of glutamate.. ...

The binding of radioactive γ-aminobutyric acid (GABA) to receptor-like sites in mammalian brain membranes was analyzed by computer for comparison with models which might explain the observed apparent heterogeneity of ligand binding. The best fit was obtained with two independent binding sites. Binding was measured by centrifugation, using thoroughly washed, frozen, and thawed membranes without detergent treatment. Assays were carried out at 0° under sodium ion-free conditions which have previously been shown to allow detection only of those binding sites having the chemical specificity and other properties expected of receptor sites for the neurotransmitter GABA. Quantitative analysis of binding curves for several brain regions, subcellular fractions, and species revealed the general presence of two affinity classes for GABA receptors, one with KD Of 13 ± 6 nM (Bmax = 0.33 pmole/mg of protein in bovine cortex) and the other with KD of 300 ± 150 nM (Bmax 1.8 pmole/mg of protein in bovine ...

BACKGROUND: AZD3043 is a positive allosteric modulator of the γ-aminobutyric acid type A receptor, with sedative and anesthetic properties. We describe a population pharmacokinetic (PK) model of arterial and venous concentrations of AZD3043 and the pharmacodynamic effects on bispectral index (BIS) in healthy volunteers.. METHODS: Arterial and venous plasma concentrations of AZD3043 and BIS were measured in 2 clinical studies in 125 healthy volunteers, where AZD3043 was given as a 1-minute bolus (1-6 mg/kg), a 30-minute infusion (1-81 mg/kg/h), or 0.8 + 10, 1 + 15, 3 + 30, and 4 + 40 (mg/kg bolus + mg/kg/h infusion for 30 minutes). Population PK/pharmacodynamic analysis was performed with NONMEM.. RESULTS: A recirculatory model, comprising a series of 5 compartments for the transit of drug between venous and arterial plasma, 2 peripheral distribution compartments, and 1 compartment for the nondistributive transit of drug from arterial to venous plasma, described the PK of AZD3043.

N2 - Background: The circadian clock is modulated by the timing of ingestion or food composition, but the effects of specific nutrients are poorly understood. Objective: We aimed to identify the amino acids that modulate the circadian clock and reset the light-induced circadian phase in mice and humans. Methods: Male CBA/N mice were orally administered 1 of 20 L-amino acids, and the circadian and light-induced phase shifts of wheel-running activity were analyzed. Antagonists of several neurotransmitter pathways were injected before L-serine administration, and light-induced phase shifts were analyzed. In addition, the effect of L-serine on ...

TY - JOUR. T1 - Assessment of the multiple discriminative stimulus effects of ethanol using an ethanol-pentobarbital-water discrimination in rats. AU - Bowen, C. A.. AU - Gatto, G. J.. AU - Grant, Kathleen (Kathy). PY - 1997. Y1 - 1997. N2 - Previous drug discrimination studies have elucidated the importance of γ-aminobutyric acid(A) (GABA(A)), N-methyl-D-aspartate (NMDA) glutamate, and serotonin (5-HT) receptor systems in mediating the discriminative stimulus effects of ethanol. The present study used a three-choice operant drug discrimination procedure in an attempt to determine if salient GABAergic effects could be separated from other stimulus effects of 2.0 g/kg ethanol. Adult male Long-Evans rats (n=7) were trained to discriminate pentobarbital (10.0 mg/kg; intragastrically (i.g.)) from ethanol (2.0 g/kg; i.g.) from water (4.7 ml; i.g.) using food reinforcement, Stimulus substitution tests were conducted following the administration of allopregnanolone (1.0-17.0 mg/kg; intraperitoncally ...

AU - Nyíri, G.. PY - 2019/5/24. Y1 - 2019/5/24. N2 - Hippocampal pyramidal cells encode memory engrams, which guide adaptive behavior. Selection of engram-forming cells is regulated by somatostatin-positive dendrite-targeting interneurons, which inhibit pyramidal cells that are not required for memory formation. Here, we found that γ-aminobutyric acid (GABA)-releasing neurons of the mouse nucleus incertus (NI) selectively inhibit somatostatin-positive interneurons in the hippocampus, both monosynaptically and indirectly through the inhibition of their subcortical excitatory inputs. We demonstrated that ...
