Differential expression of alpha2-6 sialylated polylactosamine structures by human B and T cells. (1/534)

We found that human peripheral B and T cells differed in the surface expression of alpha2-6 sialylated type 2 chain glycans. In contrast to B cells, T cells expressed only sialoglycans with repeated N-acetyllactosamine (Galss1-4GlcNAc) disaccharides. This finding was based on the specificity of the monoclonal antibodies HB6, HB9 (CD24), HD66 (CDw76), FB21, and CRIS4 (CDw76) with the alpha2-6 sialylated model gangliosides IV6NeuAcnLc4Cer (2-6 SPG), VI6NeuAcnLc6Cer (2-6 SnHC), VIII6NeuAcnLc8Cer (2-6 SnOC), and X6NeuAcnLc10Cer (2-6 SnDC). We found that, in addition to their common requirement of an alpha2-6 bound terminal sialic acid for binding, the antibodies displayed preferences for the length of the carbohydrate backbones. Some of them bound mainly to 2-6 SPG with one N-acetyllactosamine (LacNAc) unit (HB9, HD66); others preferentially to 2-6 SnHC and 2-6 SnOC, with two and three LacNAc units, respectively (HB6 and FB21); and one of them exclusively to very polar alpha2-6 sialylated type 2 chain antigens (CRIS4) such as to 2-6 SnOC and even more polar gangliosides with three and more LacNAc units. These specificities could be correlated with the cellular binding of the antibodies as follows: whereas all antibodies bound to human CD 19 positive peripheral B cells, their reactivity with CD3 positive T cells was either nearly lacking (HD66, HB9), intermediate (about 65%: HB6, FB21) or strongly positive (CRIS4, 95%). Thus, the binding of the antibodies to 2-6 sialylated glycans with multiple lactosamine units appeared to determine their binding to T-cells.  (+info)

Enzymatic synthesis of alpha3'sialylated and multiply alpha3fucosylated biantennary polylactosamines. A bivalent [sialyl diLex]-saccharide inhibited lymphocyte-endothelium adhesion organ-selectively. (2/534)

Multifucosylated sialo-polylactosamines are known to be high affinity ligands for E-selectin. PSGL-1, the physiological ligand of P-selectin, is decorated in HL-60 cells by a sialylated and triply fucosylated polylactosamine that is believed to be of functional importance. Mimicking some of these saccharide structures, we have synthesized enzymatically a bivalent [sialyl diLex]-glycan, Neu5Acalpha2-3'Lexbeta1-3'Lexbeta1-3'(Neu5Acalpha2-3'Lexbeta1-3Lexbe ta1-6')LN [where Neu5Ac is N-acetylneuraminic acid, Lex is the trisaccharide Galbeta1-4(Fucalpha1-3)GlcNAc and LN is the disaccharide Galbeta1-4GlcNAc]. Several structurally related, novel polylactosamine glycans were also constructed. The inhibitory effects of these glycans on two L-selectin-dependent, lymphocyte-to-endothelium adhesion processes of rats were analysed in ex-vivo Stamper-Woodruff binding assays. The IC50 value of the bivalent [sialyl diLex]-glycan at lymph node high endothelium was 50 nm, but at the capillaries of rejecting cardiac allografts it was only 5 nm. At both adhesion sites, the inhibition was completely dependent on the presence of fucose units on the sialylated LN units of the inhibitor saccharide. These data show that the bivalent [sialyl diLex]-glycan is a high affinity ligand for L-selectin, and may reduce extravasation of lymphocytes at sites of inflammation in vivo without severely endangering the normal recirculation of lymphocytes via lymph nodes.  (+info)

Molecular cloning of a novel alpha2,3-sialyltransferase (ST3Gal VI) that sialylates type II lactosamine structures on glycoproteins and glycolipids. (3/534)

A novel member of the human CMP-NeuAc:beta-galactoside alpha2, 3-sialyltransferase (ST) subfamily, designated ST3Gal VI, was identified based on BLAST analysis of expressed sequence tags, and a cDNA clone was isolated from a human melanoma line library. The sequence of ST3Gal VI encoded a type II membrane protein with 2 amino acids of cytoplasmic domain, 32 amino acids of transmembrane region, and a large catalytic domain with 297 amino acids; and showed homology to previously cloned ST3Gal III, ST3Gal IV, and ST3Gal V at 34, 38, and 33%, respectively. Extracts from L cells transfected with ST3Gal VI cDNA in a expression vector and a fusion protein with protein A showed an enzyme activity of alpha2, 3-sialyltransferase toward Galbeta1,4GlcNAc structure on glycoproteins and glycolipids. In contrast to ST3Gal III and ST3Gal IV, this enzyme exhibited restricted substrate specificity, i.e. it utilized Galbeta1,4GlcNAc on glycoproteins, and neolactotetraosylceramide and neolactohexaosylceramide, but not lactotetraosylceramide, lactosylceramide, or asialo-GM1. Consequently, these data indicated that this enzyme is involved in the synthesis of sialyl-paragloboside, a precursor of sialyl-Lewis X determinant.  (+info)

Isolation and characterization of linear polylactosamines containing one and two site-specifically positioned Lewis x determinants: WGA agarose chromatography in fractionation of mixtures generated by random, partial enzymatic alpha3-fucosylation of pure polylactosamines. (4/534)

We report that isomeric monofucosylhexasaccharides, Galbeta1-4GlcNAcbeta1-3Galbeta1-4GlcNAcbeta1- 3Galbeta1-4(Fucalpha1-3) GlcNAc, Galbeta1-4GlcNAcbeta1-3Galbeta1-4(Fucalpha1-3) GlcNAcbeta1-3Galbeta1-4 GlcNAc and Galbeta1-4(Fucalpha1-3)GlcNAcbeta1-3Galbeta1- 4GlcNAcbeta1-3Galbeta1-4 GlcNAc, and bifucosylhexasaccharides Galbeta1-4GlcNAcbeta1-3Galbeta1-4(Fucalpha1-3) GlcNAcbeta1-3Galbeta1-4(Fucalpha1-3)GlcNAc, Galbeta1-4(Fucalpha1-3)GlcNAcbeta1-3Galbeta1- 4GlcNAcbeta1-3Galbeta1-4 (Fucalpha1-3)GlcNAc and Galbeta1-4(Fucalpha1-3)GlcNAcbeta1-3Galbeta1-4( Fucalpha1-3)GlcNAcbeta1-3Galbeta1-4GlcNAc can be isolated in pure form from reaction mixtures of the linear hexasaccharide Galbeta1-4GlcNAcbeta1-3Galbeta1-4GlcNAcbeta1- 3Galbeta1-4GlcNAc with GDP-fucose and alpha1,3-fucosyltransferases of human milk. The pure isomers were characterized in several ways;1H-NMR spectroscopy, for instance, revealed distinct resonances associated with the Lewis x group [Galbeta1-4(Fucalpha1-3)GlcNAc] located at the proximal, middle, and distal positions of the polylactosamine chain. Chromatography on immobilized wheat germ agglutinin was crucial in the separation process used; the isomers carrying the fucose at the reducing end GlcNAc possessed particularly low affinities for the lectin. Isomeric monofucosyl derivatives of the pentasaccharides GlcNAcbeta1-3Galbeta1-4GlcNAcbeta1-3Galbeta1- 4Gl cNAc and Galalpha1-3Galbeta1-4GlcNAcbeta1-3Galbeta1-4G lcN Ac and the tetrasaccharide Galbeta1-4GlcNAcbeta1-3Galbeta1-4GlcNAc were also obtained in pure form, implying that the methods used are widely applicable. The isomeric Lewis x glycans proved to be recognized in highly variable binding modes by polylactosamine-metabolizing enzymes, e.g., the midchain beta1,6-GlcNAc transferase (Leppanen et al., Biochemistry, 36, 13729-13735, 1997).  (+info)

Characterization of the substrate specificity of alpha1,3galactosyltransferase utilizing modified N-acetyllactosamine disaccharides. (5/534)

alpha1,3galactosyltransferase (alpha1,3GalT) catalyzes the synthesis of a range of glycoconjugates containing the Galalpha1,3Gal epitope which is recognized by the naturally occurring human antibody, anti-Gal. This enzyme may be a useful synthetic tool to produce a range of compounds to further investigate the binding site of anti-Gal and other proteins with a Galalpha1,3Gal binding site. Thus, the enzyme has been probed with a series of type 2 disaccharide-C8(Galbeta1-4GlcNAc-C8) analogs. The enzyme tolerated acceptors with modifications at C2 and C3 of the N-acetylglucosamine residue, producing a family of compounds with a nonreducing alpha1,3 linked galactose. Compounds that did not serve as acceptors were evaluated as inhibitors. Interestingly, the type 1 disaccharide-C8, Galbeta1-3GlcNAc-C8, was a good inhibitor of the enzyme (Ki = 270 microM vs. Km = 190 microM for Galbeta1-4GlcNAc-C8). A potential photoprobe, based on a modified type 2 disaccharide (octyl 3-amino-3-deoxy-3-N-(2-diazo-3, 3, 3-trifluoropropionyl-beta-D-galactopyranosyl-(1, 4)-2-acetamindo-2-deoxy-beta-D-glycopyranoside, (DTFP-LacNAc-C8)), was evaluated as an inhibitor of alpha1,3GalT. alpha1,3GalT bound DTFP-LacNAc-C8 with an affinity (Ki = 300 microM) similar to that displayed by the enzyme for LacNAc-C8. Additional studies were done to determine the enzyme's ability to transfer a range of sugars from UDP-sugar donors. The results of these experiments demonstrated that alpha1,3GalT has a strict specificity for UDP-Gal. Finally, inactivation studies with various amino acid modifiers were done to obtain information on the importance of different types of amino acids for alpha1,3GalT activity.  (+info)

Effects of egg-adaptation on the receptor-binding properties of human influenza A and B viruses. (6/534)

Propagation of human influenza viruses in embryonated chicken eggs (CE) results in the selection of variants with amino acid substitutions near the receptor-binding site of the hemagglutinin (HA) molecule. To evaluate the mechanisms by which these substitutions enable human virus growth in CE, we studied the binding of 10 human influenza A (H1N1, H3N2) and B strains, isolated and propagated solely in MDCK cells, and of their egg-adapted counterparts to preparations of cellular membranes, gangliosides, sialylglycoproteins, and sialyloligosaccharides. All egg-adapted variants differed from nonadapted strains by increased binding to the plasma membranes of chorio-allantoic (CAM) cells of CE and by the ability to bind to CAM gangliosides. In addition, there was no decrease in affinity for inhibitors within allantoic fluid. These findings indicate that growth of human influenza viruses in CE is restricted because of their inefficient binding to receptors on CAM cells and that gangliosides can play an important role in virus binding and/or penetration. The effects of the egg-adaptation substitutions on the receptor-binding properties of the viruses include (i) enhancement of virus binding to the terminal Sia(alpha2-3)Gal determinant (substitutions in HA positions 190, 225 of H1N1 strains and in position 186 of H3N2 strains); (ii) a decrease of steric interference with more distant parts of the Sia(alpha2-3Gal)-containing receptors (a loss of glycosylation sites in positions 163 of H1 HA and 187 of type B HA); and (iii) enhanced ionic interactions with the negatively charged molecules due to charged substitutions at the tip of the HA [187, 189, 190 (H1), and 145, 156 (H3)]. Concomitantly with enhanced binding to Sia(alpha2-3)Gal-terminated receptors, all egg-adapted variants decreased their affinity for equine macroglobulin, a glycoprotein bearing terminal 6'-sialyl(N-acetyllactosamine)-moieties.  (+info)

Lipid A modifications characteristic of Salmonella typhimurium are induced by NH4VO3 in Escherichia coli K12. Detection of 4-amino-4-deoxy-L-arabinose, phosphoethanolamine and palmitate. (7/534)

Two-thirds of the lipid A in wild-type Escherichia coli K12 is a hexa-acylated disaccharide of glucosamine in which monophosphate groups are attached at positions 1 and 4'. The remaining lipid A contains a monophosphate substituent at position 4' and a pyrophosphate moiety at position 1. The biosynthesis of the 1-pyrophosphate unit is unknown. Its presence is associated with lipid A translocation to the outer membrane (Zhou, Z., White, K. A., Polissi, A., Georgopoulos, C., and Raetz, C. R. H. (1998) J. Biol. Chem. 273, 12466-12475). To determine if a phosphatase regulates the amount of the lipid A 1-pyrophosphate, we grew cells in broth containing nonspecific phosphatase inhibitors. Na2WO4 and sodium fluoride increased the relative amount of the 1-pyrophosphate slightly. Remarkably, NH4VO3-treated cells generated almost no 1-pyrophosphate, but made six major new lipid A derivatives (EV1 to EV6). Matrix-assisted laser desorption ionization/time of flight mass spectrometry of purified EV1 to EV6 indicated that these compounds were lipid A species substituted singly or in combination with palmitoyl, phosphoethanolamine, and/or aminodeoxypentose residues. The aminodeoxypentose residue was released by incubation in chloroform/methanol (4:1, v/v) at 25 degrees C, and was characterized by 1H NMR spectroscopy. The chemical shifts and vicinal coupling constants of the two anomers of the aminodeoxypentose released from EV3 closely resembled those of synthetic 4-amino-4-deoxy-L-arabinose. NH4VO3-induced lipid A modification did not require the PhoP/PhoQ two-component regulatory system, and also occurred in E. coli msbB or htrB mutants. The lipid A variants that accumulate in NH4VO3-treated E. coli K12 are the same as many of those normally found in untreated Salmonella typhimurium and Salmonella minnesota, demonstrating that E. coli K12 has latent enzyme systems for synthesizing these important derivatives.  (+info)

Role of lactosyl glycan sequences in inhibiting enteropathogenic Escherichia coli attachment. (8/534)

Previously, we found that asialo-lactosamine sequences served as receptors for enteropathogenic Escherichia coli (EPEC) binding to Chinese hamster ovary (CHO) cells. In the present report, we have extended these earlier results by examining the ability of lactosamine- or fucosylated lactosamine-bovine serum albumin (BSA) glycoconjugates to inhibit EPEC, strain E2348/69, binding to HEp-2 cells. We found that, consistent with our previous findings with CHO cells, N-acetyllactosamine-BSA was the most effective inhibitor of EPEC localized adherence to HEp-2 cells, with Lewis X-BSA being the next best inhibitor. Further investigation revealed that coincubating EPEC E2348/69 with these BSA glycoconjugates alone caused a decrease in the expression of the bundle-forming pilus structural subunit (BfpA) and intimin by the bacteria. BfpA and intimin expression were reduced to the greatest extent by N-acetyllactosamine-BSA and Lewis X-BSA, respectively. These results suggest that the glycoconjugate inhibition of EPEC binding to HEp-2 cells might be achieved, wholly or in part, by an active mechanism that is distinct from simple competitive antagonism of receptor-adhesin interactions.  (+info)

Chemo-enzymatic modification of poly-N-acetyllactosamine (LacNAc) oligomers and N,N-diacetyllactosamine (LacDiNAc) based on galactose oxidase treatment
Gelatinase B (MMP-9) and galectin-3 are widely known to participate in tumor cell invasion and metastasis. Glycans derived from MMP-9 expressed in MCF-7 breast cancer and THP-1 myeloid leukemia cells were compared with those from MMP-9 expressed in natural neutrophils. The many O-linked glycans of neutrophil gelatinase B presented a cluster of mainly galactosylated core II structures, 46% of which were ligands for galectin-3; 11% contained two to three N-acetyllactosamine repeating units that are high-affinity ligands for the lectin. The glycan epitopes thus provide MMP-9 with both high-affinity and (presumably) high-avidity interactions with galectin-3. In contrast, the O-glycans released from MMP-9 expressed in MCF-7 and THP-1 cells were predominantly sialylated core I structures. Only 10% of MCF-7 and THP-1 gelatinase B O-glycans were ligands for galectin-3 and contained only a maximum single N-acetyllactosamine repeat. Consistent with the glycan analysis, surface plasmon resonance binding ...

Our previous observations that human CD8 TIL increased their secretion of IFN-γ after ex vivo treatment with disaccharide LacNAc prompted us to test GCS-100, a polymeric galectin ligand approved for clinical trials. The results reported here indicate that GCS-100 is as efficient as LacNAc in boosting TIL to be cytotoxic and to secrete different cytokines, not only CD8+ but also CD4+ TIL. This effect was obtained at concentrations (5 μg/mL) much lower than those used to induce apoptosis of tumor cells (,100 μg/mL), the activity that prompted its administration to cancer patients (30).. Why do galectin-3 ligands improve human TIL function? Our working hypothesis is that TILs have been stimulated by antigen recently and that activation could modify the expression of enzymes of the N-glycosylation pathway and change the structure of N-glycans exposed at the cell surface, as shown for murine T cells (45). We surmise that the recently activated TILs, compared with resting T cells, harbor a set of ...

Scientists may have found a way to kill Burkholderia cenocepacia, a multi-drug resistant plant pathogen that causes severe infections in people with cystic fibrosis.. The team of researchers has identified a weakness in the armour that protects the B. cenocepacia bacterium from the effects of antibiotics. They hypothesize that preventing the synthesis of a key sugar required for this armour, 4-amino-4-deoxy-L-arabinose (Ara4N), may lead to a susceptibility within the cell membrane to antibiotics. Researchers hope to discover novel molecules as antibiotic candidates which could disrupt the synthesis of Ara4N.. ...

Glucosamine is an amino sugar that helps in the biochemical synthesis of protein and lipids. In laymens terms, glucosamine helps proteins and lipids absorb into your ligaments, cartilage, tendons, bones, and tendons. This helps you keep your body flexible, and helps keep arthritis at bay. While it is inevitable that many of us will get some form of arthritis, taking a glucosamine supplement can alleviate the severity of the arthritis. It also helps alleviate the severity of arthritis that already exists.. Controversy aside, there have been animal studies that find that glucosamine can elongate the lifespan of those animals that consume glucosamine, as compared to animals that do not. The National Institute of Health found in 2014 that nematodes given gluosamine supplements lived longer than those who did not receive any supplement. The study found that in addition to the fat and protein transfer to bones and joints, glucosamine gave the nematodes a big boost in antioxidants which help liven up ...

100 Easy-Solv™ Tablets 1000 mg each Glucosamine Hydrochloride HCI Usage: Take 1 or 2 tablets each day, or as directed by your qualified health consultant. Do NOT use if allergic to shellfish. Easy-Solv™ tablets are designed to disintegrate within several minutes of ingestion. Do NOT take if allergic to shellfish. Glucosamines are chemically classified as amino sugars, which are molecules synthesized from sugars and amino acids. Most amino sugars found in our body are obtained by de novo (internal) production. In the case of glucosamine, the enzyme glucosamine synthetase combines glucose and glutamine to form glucosamine. Amino sugars are also commonly called proteoglycans. Glucosamine is an aminosaccharide synthesized by transamidase enzymes from glucose and an amine group from glutamine. HCI (hydrochloric acid) stabilizes the glucosamine in this product. Glucosamine is a component of joint and intestinal tissue and is involved in the production of synovial fluid which lubricates
Do you think you are doing yourself a favor and being smart by selecting foods off the grocers shelf that are labeled sugar free, or no added sugar, or lower sugar than a competing product. Research shows that you are kidding yourself. For one thing most products labeled lower sugar, or no added sugar or sugar free, are still full of simple carbohydrates, extra sodium and fat. Many times for example the "No Sugar Added" pie at your local grocery store sells for 2X what the regular pie of the same kind sells for. In one local store near where I live, the no sugar added pie is a 1/2 pie and sells for around $7.59 while the same full sized pie sells for $4.00 most of the time. One would be better off exercising portion control and buying the regular pie, especially if one of the ingredients is ASPARTAME. In many cases the Sugar Free pie will have as many carbohydrates as the sugar free pie. Remember that your body turns simple carbohydrates into sugar anyway ...

Peptidoglycan is a macromolecule made of long aminosugar strands cross-linked by short peptides. It forms the cell wall in bacteria surrounding the cytoplasmic membrane. The glycan strands are typically comprised of repeating N-acetylglucosamine (GlcNAc) and N-acetylmuramic acid (MurNAc) disaccharides. Each MurNAc is linked to a peptide of three to five amino acid residues. Disaccharide subunits are first assembled on the cytoplasmic side of the bacterial membrane on a polyisoprenoid anchor (lipid I and II). Polymerization of disaccharide subunits by transglycosylases and cross-linking of glycan strands by transpeptidases occur on the other side of the membrane. Bacterial cell wall biosynthesis inhibitors form a major class of antibiotics ...

In this thesis, the syntheses of oligosaccharides for interaction studies with various lectins are described. The first section reports the syntheses of tetra, tri- and disaccharides corresponding to truncated versions of the glucosylated arm of Glc1Man9(GlcNAc)2, found in the biosynthesis of N-glycans. The thermodynamic parameters of their interaction with calreticulin, a lectin assisting and promoting the correct folding of newly synthesised glycoproteins, were established by isothermal titration calorimetry. In the second section, a new synthetic pathway leading to the same tetra- and trisaccharides is discussed. Adoption of a convergent strategy and of a different protecting group pattern resulted in significantly increased yields of the target structures. The third section describes the syntheses of a number of monodeoxy-trisaccharides related to the above trisaccharide Glc-α-(1→3)-Man-α-(1→2)-Man-α-OMe. Differentsynthetic approaches were explored and the choice of early introduction ...
Glucosamine sulphate is an amino sugar formed from glucose and the amino acid glutamine. Normally made by the digestive process, Glucosamine Sulphate is fundamental in all connective tissue manufacture. Connective tissue or collagen is rich in protoglycans, which are made up of glycosaminoglycans (GAGs) and protein. Glucosamine Sulphate is the main precursor in GAG production. Of the three commonly available forms of glucosamine, only glucosamine sulfate is given a "likely effective" rating for treating osteoarthritis.. It appears that as some animals age, like humans, they do not manufacture enough GAG, one of the major causes of osteoarthritis. Supplementation with orally administered Glucosamine Sulphate has been shown to be very beneficial in the treatment of osteoarthritis.. Good diet is essential as is the need to maintain weight at normal or slightly below.. Suggested additions:. Non acidic vitamin C. Vitamin C is essential to cartilage repair and manufacture ...

It is then that an ischemic attack occurs, a pathology that leads to the degeneration of neurones, which can be fatal and not many drugs can treat.. Now, German and Swiss scientists have discovered that the combination of two substances help to reduce inflammation and the brain volume affected after a cerebrovascular accident. This is glucosamine, an amino sugar commonly used to treat arthritis and arthrosis; and certain derivatives of fullerenes, hollow and spherical structures formed by many carbon atoms.. Before now it was known that the fullerenes capture chemical radicals well which makes them act as neuroprotective agents, while the glucosamine brings down the inflammation.. What the researchers have done is chemically bond the two compounds to produce what is known as glyconanoparticles. These have subsequently been ...

Bacteria take up and metabolize sugar as a carbohydrate source for survival. Most bacteria can utilize many sugars, including glucose, sucrose, and galactose, as well as amino sugars, such as glucosamine and N-acetylglucosamine. After entering the cytoplasm, the sugars are mainly allocated to the glycolysis pathway (energy production) and to various bacterial component biosynthesis pathways, including the cell wall, nucleic acids and amino acids. Sugars are also utilized to produce several virulence factors, such as capsule and lipoteichoic acid. Glutamine-fructose-6-phosphate aminotransferase (GlmS) and glucosamine-6-phosphate deaminase (NagB) have crucial roles in sugar distribution to the glycolysis pathway and to cell wall biosynthesis. In Streptococcus mutans, a cariogenic pathogen, the expression levels of glmS and nagB are coordinately regulated in response to the presence or absence of amino sugars. In addition, the disruption of this regulation affects the virulence of S. mutans. The expression
