A novel domain of the inhibitory glycine receptor determining antagonist efficacies: further evidence for partial agonism resulting from self-inhibition. (1/351)

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)

Novel strategies for the design of receptor-selective vasopressin analogues: Aib-substitution and retro-inverso transformation. (2/351)

1. We determined the pharmacological profile of novel backbone-modified peptides designed as protease-resistant, selective analogues of AVP. Binding affinities of peptides were determined at both V1A and V2 subtypes of vasopressin receptor (VPR). Biological potencies of selected peptides were tested in pressor and antidiuretic bioassays. 2. Substitution of the achiral alpha-aminoisobutyric acid (Aib) at position 4 or 7 of AVP produced peptides that selectively bound the V2 VPR. Both [Aib4]AVP (140 IU mg-1) and [Aib7]AVP (36 IU mg-1) are selective antidiuretic agonists with little or no activity in uterotonic and pressor assays. 3. [Aib4] and [Aib7] derivatives of the linear V1A-selective antagonist [PhaaDTyr(Et)2Arg6Tyr(NH2)9]AVP bound selectively and with high affinity (Kd 0.51 and 4.1 nM respectively) to the V1A VPR. Bioassays confirmed that these peptides were potent antivasopressor agents (pA2 8.10 and 8.36 respectively). 4. A total retro-inverso strategy was used to prepare protease-resistant mimetics of both AVP and linear V1A-selective antagonists. Cyclic retro-inverso mimetics of AVP did not bind either V1A or V2 VPRs. In contrast, rationally designed retro-inverso mimetics of linear V1A-selective antagonists selectively bound the V1A VPR. 5. Our findings indicate novel methods to improve the pharmacodynamic and pharmacokinetic parameters of neurohypophysial hormone analogues which could be equally applicable to other peptide-receptor systems.  (+info)

Cloning and functional identification of a neuronal glutamine transporter. (3/351)

Glutamine is the preferred precursor for the neurotransmitter pool of glutamate, the major excitatory transmitter in the mammalian central nervous system. We have isolated a complementary DNA clone (designated GlnT) encoding a plasma membrane glutamine transporter from glutamatergic neurons in culture, and its properties have been examined using the T7 vaccinia system in fibroblasts. When GlnT is transfected into CV-1 cells, L-glutamine is the preferred substrate. Transport is Na(+)-dependent and inhibited by alpha-methylaminoisobutyric acid, a specific inhibitor of neutral amino acid transport system A. Kinetic analysis of glutamine uptake by GlnT is saturable, with a Michaelis constant (K(m)) of 489 +/- 88 microM at pH 7.4. Glutamine uptake mediated by GlnT is pH-sensitive with a 5-fold greater efficiency of uptake at pH 8.2 than at pH 6.6. Only the maximal velocity of transport increases without a significant change in K(m). The distribution of GlnT mRNA and protein in the central nervous system is widespread and is expressed on neurons that use glutamate as their neurotransmitter. In cultured cerebellar granule cells, GlnT is expressed only on neurons and is absent from astrocytes. GlnT expression increases concomitantly with the morphologic and functional differentiation of these cells in vitro, consistent with its role of supplying glutamatergic neurons with their neurotransmitter precursor. GlnT is the first member of the system A family of neutral amino acid transporters with 11 putative membrane-spanning domains and is a potential target to modulate presynaptic glutamatergic function.  (+info)

Effects of duration of positive-pressure ventilation on blood-brain barrier function in premature lambs. (4/351)

We have been studying the ontogeny of the blood-brain barrier function in ovine fetuses and lambs. During these studies, we have found that the duration of ventilation also influences blood-brain barrier permeability in premature lambs. Chronically instrumented hysterotomy-delivered surfactant-treated premature lambs were studied at 90% or 137 days of gestation (n = 9). Blood-brain barrier function was quantified with the blood-to-brain transfer constant K(i) to alpha-aminoisobutyric acid. Linear regression analysis was used to compare the K(i) values in the brain regions, as the dependent variable, to the duration of ventilation, as the independent variable. There were direct correlations (P < 0.05) between the K(i) values and the duration of ventilation [306 min (mean), 162-474 min (range)] in the cerebral cortex, cerebellum, medulla, caudate nucleus, hippocampus, superior colliculus, inferior colliculus, thalamus, pons, cervical spinal cord, and choroid plexus, but not in the pituitary gland. Ventilatory pressures and rates were established before the onset of the permeability studies. Calculated mean airway pressures [14 cmH(2)O (mean), 7-20 cmH(2)O (range)] from similarly studied premature lambs did not correlate with the duration of positive-pressure ventilation. We conclude that increases in the duration of positive-pressure ventilation predispose premature lambs to increases in regional blood-brain barrier permeability. These alterations in barrier function occur over relatively short time intervals (minutes to hours). In our study, these changes in permeability are most likely not attributable to changes in mean airway pressure.  (+info)

Studies on convulsants in the isolated frog spinal cord. I. Antagonism of amino acid responses. (5/351)

1. The isolated frog spinal cord was used to study the effects of picrotoxin, bicuculline, and strychnine on the responses of primary afferents to amino acids. Recording was by sucrose gap technique. 2. A series of neutral amino acids was found to depolarize primary afferents. Optimal activity was obtained by an amino acid whose carboxyl and amino groups were separated by a three-carbon chain length (i.e. GABA). Amino acids with shorter (i.e. beta-alanine, glycine) or longer (i.e. delta-aminovaleric acid, epsilon-aminocaproic acid) distances between the charged groups were less potent. Imidazoleacetic acid was the most potent depolarizing agent tested. 3. Picrotoxin and bicuculline antagonized the primary afferent depolarizations of a number of amino acids tested with equal specificity. Depolarizing responses to standard (10- minus 3 M) concentrations of beta-alanine and taurine were completely blocked by these convulsants, while depolarizations to 10- minus 3 gamma-aminobutyric acid (GABA) were only partially antagonized. Glycine responses were unaffected by these agentsk; Strychnine completely blocked beta-alanine and taurine depolarizations and incompletely antagonized several other neutral amino acids. GABA, glutamate, and glycine depolarizations were not affected. 5. These results suggest that there are at least three distinct populations of neutral amino acid receptors on primary afferent terminals: a GABA-like receptor, a taurine/beta-alanine receptor, and a glycine-like receptor. The strychnine resistance of the glycine responses indictaes that the primary afferent receptors for glycine differ from those on the somata of spinal neurones.  (+info)

Nucleocytoplasmic transport and distribution of an amino acid, in situ. (6/351)

Ultra-low temperature techniques (microdissection and autoradiography) were used to study the nucleocytoplasmic distribution and transport of alpha-aminoisobutyric acid (AIB) in an amino acid-accumulating cell. In amphibiam oocytes incubated in AIB, the nuclear concentration of this non-metabolizable amino acid exceeds the cytoplasmic concentration by 45%, remaining constant both over time and variation in substrate concentration. The kinetics of uptake suggest that this nucleo-cytoplasmic asymmetry arises from solubility differences between the 2 compartments, and that the nuclear envelope plays a negligible role in amino acid transport. A solute exclusion model is offered to explain the nucleocytoplasmic asymmetry.  (+info)

Transport mechanisms of 3-[123I]iodo-alpha-methyl-L-tyrosine in a human glioma cell line: comparison with [3H]methyl]-L-methionine. (7/351)

The amino acid analog 3-[(123)I]iodo-alpha-methyl-L-tyrosine (IMT) is under clinical evaluation as a SPECT tracer of amino acid transport in brain tumors. This study investigated the carrier systems involved in IMT transport in human glioma cells in comparison with [3H-methyl]-L-methionine (3H-MET). METHODS: Human glioma cells, type 86HG-39, were cultured and incubated for 1 min at 37 degrees C with IMT and 3H-MET in the lag phase (1.2 d after seeding), exponential growth phase (3 d after seeding), and plateau phase (8 d after seeding). Experiments were performed in the presence and absence of Na+, during inhibition of system L amino acid transport by 2-aminobicyclo[2.2.1 ]heptane-2-carboxylic acid (BCH), and during inhibition of system A amino acid transport by 2-(methylamino)-isobutyric acid (MeAIB). RESULTS: IMT and 3H-MET uptake decreased by 55%-73% when the cells entered from the exponential growth phase into the plateau phase (P< 0.05; n = 3-11). Inhibition by BCH reduced uptake of IMT in the lag phase, exponential growth phase, and plateau phase by 90%-98% (P < 0.001; n = 3-6) and the uptake of 3H-MET by 73%-83% (P < 0.001; n = 3-11). In a Na+-free medium 3H-MET uptake was reduced by 23%-33% (P < 0.05; n = 3-11), whereas IMT uptake was not significantly different. MeAIB showed no significant effect on IMT or 3H-MET uptake in either phase. CONCLUSION: Transport of both IMT and 3H-MET depends on the proliferation rate of human glioma cells in vitro and is dominated by BCH-sensitive transport. These data indicate that system L is induced in rapidly proliferating glioma cells and is the main contributor to the uptake of both tracers. 3H-MET transport showed a minor Na+ dependency that was not attributable to system A. The similarity of transport mechanisms of both tracers emphasizes the clinical equivalence of IMT SPECT and (11)C-MET PET for the diagnostic evaluation of gliomas.  (+info)

Epidermal growth factor regulates amino acid transport in chick embryo hepatocytes via protein kinase C. (8/351)

System A-mediated amino acid transport, activation of different steps of signal transduction and involvement of different isoforms of protein kinase C (PKC) have been investigated in chick embryo hepatocytes after epidermal growth factor (EGF) stimulation. EGF rapidly (10 min) increased the rate of aminoisobutyric acid (AIB) uptake in chick embryo hepatocytes freshly isolated on the 19th day of embryonic life, while no change was detectable at other embryonal stages. The growth factor stimulation was abolished by PKC and tyrosine kinase inhibitors and was mimicked by 4-phorbol-12-myristate-13-acetate, dimethyl-2 (PMA). EGF treatment did not modify the phosphorylation of the isoform of phospholipase C (PLC-), and inositol trisphosphate (IP3) and intracellular calcium levels, but it induced an increase in PKC activity. Our data show that EGF regulates amino acid uptake, via PKC and without PLC- activation, only in the last period of chick embryo hepatocyte development. The effects of growth factor on PKC activity suggest the involvement of PKC- and - isoforms in EGF modulation of amino acid transport.  (+info)

rs37369 is a SNP located in the coding region of the alanine-glyoxylate aminotransferase-2 (AGXT2) gene within chromosome 5 at position 35,072,872. This polymorphism constitues a nonsynonymous valine-to-isoleucine (V140I) substitution in the AGXT2 protein. rs37369 has been proposed by one study to be the causative SNP of hyper-beta-aminoisobutyric aciduria. Beta-aminoisobutyric acid (BAIB) is the end product of pyrimidine metabolism. Hyper-BAIB is an autosomal recessive phenotype that is distinguished by high urinary excretion levels of beta-aminoisobutyric acid [PMID 10819024]. Elevated levels of BAIB have been suggested to contribute to neurological and developmental problems, as BAIB is a structural analog of gamma-aminobutyric acid and glycine--two major inhibitory neurotransmitters in the central nervous system [PMID 15385443]. The Online Mendelian Inheritance in Man (OMIM) database states that hyper-beta-aminoisobutyric aciduria is likely the most common Mendelian metabolic variant in man ...
Albumin synthesis was measured in the isolated perfused rat liver by using the livers of both well-fed and starved rats. Starvation markedly decreased albumin synthesis. The livers from starved rats were unable to increase synthesis rates after the addition to the perfusates of single amino acids or the addition of both glucagon and tryptophan. Arginine, asparagine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, threonine, tryptophan and valine, added together to ten times their normal peripheral blood concentrations, restored synthesis rates to normal. The plasma aminogram (i.e. the relative concentrations, of amino acids) was altered by depriving rats of protein for 48h. The use of blood from the deprived rats as perfusate, instead of normal blood, decreased albumin synthesis rates significantly by livers obtained from well-fed rats. The addition of single amino acids, including the non-metabolizable amino acid, α-aminoisobutyric acid, to the above mixture increased albumin ...

We use mixed classical/quantum simulations to study the time dependence of an excitation of a C=O vibration on a 3-10 helix of $\alpha$-Aminoisobutyric acid (AIB), a system which represents a test case for the formation of self-trapped vibrational excitation states on protein helices. Due to the inherent disorder in the system caused by the finite temperature and fluctuations in hydrogen bonding, the excitation tunnels randomly among C=O sites along the helix. Quantum forces are insufficient to establish a coherent relationship between the location of the excitation and the contraction of hydrogen bonds around this site. Our simulations indicate that the excitation frequently becomes localized on the end of the helix due to the defect in helical structure caused by unwinding. Our results generally do not support the existance of Davydov type solitons in biological helix systems under physiological conditions ...
The presented examples demonstrate that 1,3-oxazol-5(4H)-ones are attractive intermediates not only for intermolecular but also for intramolecular reactions with nucleophiles. With a series of examples, the potential of these reactions was exemplified. The reactions of 1,3-oxazol-5(4H)-ones, as starting materials or as intermediates, bearing the nucleophilic group in ω-postion of the substituent at C(2), belong to real ring enlargement reactions as all atoms of the oxazolone ring are included in the new ring. They proceed under acid catalysis, e.g. under the conditions of the direct amide cyclization. Together with the azirine/oxazolone method for the introduction of α,α-disubstituted α-amino acids into peptides, these reactions are ideally suited for the synthesis of cyclodepsipeptides and cyclopeptides, especially of sterically congested ones, which contain α-aminoisobutyric acid (Aib) or other α,α-disubstituted glycines. On the other hand, 4,4-disubstituted 1,3-oxazol-5(4H)-ones ...
Transport of α-aminoisobutyric acid and 2-deoxy-d-glucose in African green monkey kidney cells was measured 8 to 100 hr following permissive simian virus 40 infection. No differences in transport were detected during the time-period studies, and no significant differences were seen between the apparent Michaelis-Menten constants of normal and virally infected cells. The absence of transport enhancement in permissive simian virus 40 infection suggests that the augmented transport of viral-transformed cell lines devolves upon altered host genome function.. ...

The underlying goal of this thesis dissertation is to simulate small monolayer protected clusters (MPCs) via quantum mechanics and molecular mechanics calculations to derive electronic, structural, and dynamical properties. First we specifically focus on monolayers consisting of thiolated oligopeptides and alkanethiols. We construct MPCs with a layer of oligopeptides consisting of α-aminoisobutyric acid units. We use Monte Carlo simulations to determine peptide arrangements and folding. We then perform NMR chemical shifts calculations and compare to experimental measurements to validate the predicted structure. The native -1 oxidation state can be oxidized into 0 and to +1 charge states. The neutral charge state is paramagnetic and behaves quite differently than the anion as manifested by the NMR spectra. The objective is to calculate NMR chemical shits, compare to experiment, and obtain insight into the electronic origin of these shifts. We also use DFT to simulate ENDOR spectra. Finally, we
Pyrimidine biosynthesis occurs both in the body and through organic synthesis. The first three enzymes are all coded by the same gene in Metazoa (CAD). In Fungi, a similar protein exists but lacks the dihydroorotase function: another protein catalyzes the second step. In other organisms (Bacteria, Archaea and the other Eukaryota), the first three steps are done by three different enzymes. Pyrimidines are ultimately catabolized (degraded) to CO2, H2O, and urea. Cytosine can be broken down to uracil, which can be further broken down to N-carbamoyl-β-alanine, and then to beta-alanine, CO2, and ammonia by beta-ureidopropionase. Thymine is broken down into β-aminoisobutyrate which can be further broken down into intermediates eventually leading into the citric acid cycle. β-aminoisobutyrate acts as a rough indicator for rate of DNA turnover. Modulating the pyrimidine metabolism pharmacologically has therapeutical uses. Pyrimidine synthesis inhibitors are used in active moderate to severe ...

The effect of ethylene and its precursor ACC on root hydraulic properties, including aquaporin expression and abundance, is modulated by relative air humidity and plant sensitivity to ethylene. Relative air humidity (RH) is a main factor contributing to water balance in plants. Ethylene (ET) is known to be involved in the regulation of root water uptake and stomatal opening although its role on plant water balance under different RH is not very well understood. We studied, at the physiological, hormonal and molecular levels (aquaporins expression, abundance and phosphorylation state), the plant responses to exogenous 1-aminocyclopropane-1-carboxylic acid (ACC; precursor of ET) and 2-aminoisobutyric acid (AIB; inhibitor of ET biosynthesis), after 24 h of application to the roots of tomato wild type (WT) plants and its ET-insensitive never ripe (nr) mutant, at two RH levels: regular (50%) and close to saturation RH ...

Cardiac arrest and resuscitation in immature piglets result in a delayed increase in blood-brain barrier permeability. We tested the hypothesis that pretreatment with oxygen radical scavengers reduces postischemic permeability.. Permeability was assessed by measuring the plasma-to-brain transfer coefficient of the small amino acid, alpha-aminoisobutyric acid, in 2- to 3-week-old anesthetized piglets. Three groups were studied: (1) a nonischemic time control group (n = 5), (2) an ischemia group (n = 8) pretreated with 5 mL of polyethylene glycol vehicle, and (3) an ischemia group (n = 8) pretreated with polyethylene glycol conjugated to superoxide dismutase (10,000 U/kg) and to catalase (20,000 U/kg). The ischemia protocol consisted of 8 minutes of ventricular fibrillation, 6 minutes of cardiopulmonary resuscitation, defibrillation, and 4 hours of spontaneous circulation.. The mean +/- SEM of the transfer coefficient of alpha-aminoisobutyric acid in cerebrum was (in microL/g per minute): 1.54 +/- ...
The relative alkali metal ion (M(+)) affinities (binding energies) between seventeen different amino acids (AA) and the corresponding methyl esters (AAOMe) were determined in the gas phase by the kinetic method based on the dissociation of AA-M(+)-AAOMe heterodimers (M=Li, Na, K, Cs). With the exception of proline, the Li(+), Na(+), and K(+) affinities of the other aliphatic amino acids increase in the order AAAAOMe is already observed for K(+). Proline binds more strongly than its methyl ester to all M(+) except Li(+). Ab initio calculations on the M(+) complexes of alanine, beta-aminoisobutyric acid, proline, glycine methyl ester, alanine methyl ester, and proline methyl ester show that their energetically most favorable complexes result from charge solvation, except for proline which forms salt bridges. The most stable mode of charge solvation depends on the ligand (AA or AAOMe) and, for AA, it gradually changes with metal ion size. Esters chelate all M(+) ions through the amine and carbonyl groups.
For repeated dose toxicity, studies were performed by Perstorp AB using NesterolTM and by Eastman using TexanolTM, both trade names for isobutyric acid, monoester with 2,2,4 -trimethylpentane-1,3 -diol. The Eastman 51 -day study in rats was selected as the key study, as it represented the longest duration and greatest exposure. The potential for TexanolTM to cause target organ toxicity following repeated exposure is well understood. One guideline repeat-exposure study and a shorter lesser study were available for review. In a combined repeat dose and reproductive/developmental toxicity screening study conducted according to OECD Guideline 422, male rats were exposed to up to 1000 mg/kg bw/day by oral gavage for 51 consecutive days while females were exposed for 40 to 51 days. For males, there were no significant treatment-related effects on mortality, clinical signs, body weight and body weight gain, feed consumption, or hematology. Although there was an increase in absolute and relative liver ...
TY - JOUR. T1 - Hyperosmotic stress up-regulates amino acid transport in vascular endothelial cells. AU - Kempson, Stephen A.. AU - Hoshaw, Martha J.. AU - Hinesley, Rose S.. AU - Mcateer, James A.. PY - 1997/1/1. Y1 - 1997/1/1. N2 - Cultured vascular endothelial cells take up L-proline by sodium- dependent transport. Cells incubated in medium made hyperosmotic by addition of sucrose showed a dose-dependent increase in Na+/proline cotransport. Studies with α-(methylamino)isobutyric acid revealed that the up-regulation was specific for amino acid transport system A. Up-regulation was blocked by actinomycin D and cycloheximide, indicating roles for gene transcription and protein synthesis. Upregulation was maximum after five to six hours of hyperosmotic treatment, but returned to control levels when osmotic stress was maintained for 24 hours. The decline at 24 hours was accompanied by a significant increase in Na+/γ-aminobutyric acid cotransport. The activity of this system, which also ...
Polymers hydrogen-bonding with solvent represent an important broad class of polymers, properties of which depend on solvation. Using atomistic molecular dynamics simulations with the OPLS/AA force field we investigate the effect of hydrogen bonding on PEO conformation and chain motility by comparing its behavior in isobutyric acid and aqueous solutions. In agreement with experimental data, we found that in isobutyric acid PEO forms a rather rigid extended helical structure, while in water it assumes highly flexible coil conformation. We show that the difference in PEO conformation and flexibility is the result of the hydrogen bond stability and overall solvent dynamics near PEO. Isobutyric acid forms up to one hydrogen bond per repeat unit of PEO and interacts with PEO for a prolonged period of time thereby stabilizing the helical structure of the polymer and reducing its segmental mobility. In contrast, water forms on average 1.2 hydrogen bonds per repeat unit of PEO (with 60% of... Read more ...

Brain-derived neurotrophic factor (BDNF) promotes the biochemical and morphological differentiation of selective populations of neurons during development. In this study we examined the energy requirements associated with the effects of BDNF on neuronal differentiation. Because glucose is the preferred energy substrate in the brain, the effect of BDNF on glucose utilization was investigated in developing cortical neurons via biochemical and imaging studies. Results revealed that BDNF increases glucose utilization and the expression of the neuronal glucose transporter GLUT3. Stimulation of glucose utilization by BDNF was shown to result from the activation of Na+/K+-ATPase via an increase in Na+ influx that is mediated, at least in part, by the stimulation of Na+-dependent amino acid transport. The increased Na+-dependent amino acid uptake by BDNF is followed by an enhancement of overall protein synthesis associated with the differentiation of cortical neurons. Together, these data demonstrate the
Glutamine is taken up into the rat hepatoma cell line H4-IIE-C3 by a Na+-dependent transport system which is specific for glutamine, alanine, serine, cysteine and asparagine and does not tolerate substitution of Na+ by Li+. Glutamine transport was relatively weakly inhibited by a 50-fold excess of leucine and was not inhibited by phenylalanine or N-methyl aminoisobutyrate. These general properties are characteristic of the recently identified ASCT/B0 family of transporters. Using a reverse transcriptase PCR-based homology cloning approach, we have characterized a cDNA for a novel member of this transporter family (H4-ASCT2) from H4-IIE-C3 cells. The cDNA encodes a 551-amino acid protein which exhibits similarities of between 75 and 85% with ASCT/B0 transporters previously cloned from other sources. When expressed in Xenopus oocytes, this transporter catalyses Na+-dependent glutamine uptake with characteristics very similar to those of glutamine uptake into the H4-IIE-C3 cells. This newly ...

Peptaibols: A group of peptides characterized by length of 1-2 dozen residues with a high proportion of them being non-proteinogenic, notably alpha-aminoisobutyric acid (Aib) and isovaline, and have a C-terminal amino alcohol and N terminal alkyl group. They are found in FUNGI and some are ANTI-INFECTIVE AGENTS. They form channels or pores in target organisms. The term is a contraction of peptide-Aib-alcohol.
The transport characteristics of amino acids in primary cell cultures from the proximal tubule of human adults (AHKE cells) were examined, using alpha-aminoisobutyric acid (AIB) and beta-alanine as representatives of alpha- and beta-amino acids, respectively. The Na(+)-gradient dependent influx of AIB occurred by a single, saturable transport system, whereas the Na(+)-gradient dependent uptake data for beta-alanine could be described in terms of two-independent transport components as well as one-transport one-leak model with identical kinetic constants for the high-affinity system. Competition experiments revealed that all the neutral amino acids tested reduced the uptake of AIB, whereas there was no effect of taurine, L-aspartic acid, and L-arginine. By contrast, the influx of beta-alanine was only drastically reduced by beta-amino acids, whereas the inhibition by neutral alpha-amino acids was relatively low. Nor did L-arginine and L-aspartic acid affect the uptake of beta-alanine into AHKE ...
TY - JOUR. T1 - The effect of cycloleucine on SFV A7(74) infection in mice. AU - Amor, S. AU - Webb, H E. PY - 1987/4. Y1 - 1987/4. N2 - Cycloleucine (CL), a non-metabolizable amino acid analogue, was found to reduce thymus and spleen weights in Semliki Forest virus (SFV) strain A7(74) infected and control mice. The maximum effects were seen when three daily doses of CL were given to mice 24 h after an SFV A7(74) infection. In these mice thymus atrophy led to abolition of thymus dependent immune responses and changes in the pathological features of the viral infection--the most striking feature being prevention of demyelination. In addition virus titres in the brains of CL treated infected mice were increased and prolonged. These results show that demyelination following an SFV A7(74) infection is not a result of direct virus action, but of a T-cell mediated mechanism.. AB - Cycloleucine (CL), a non-metabolizable amino acid analogue, was found to reduce thymus and spleen weights in Semliki ...
