Abstract
The Paramyxoviridae family includes enveloped single-stranded negative-sense RNA viruses such as measles, mumps, human parainfluenza, canine distemper, Hendra, and Nipah viruses, which cause a tremendous global health burden. The ability of paramyxoviral glycoproteins to merge viral and host membranes allows entry of the viral genome into host cells, as well as cell-cell fusion, an important contributor to disease progression. Recent molecular and structural advances in our understanding of the paramyxovirus membrane fusion machinery gave rise to various therapeutic approaches aiming at inhibiting viral infection, spread, and cytopathic effects. These therapeutic approaches include peptide mimics, antibodies, and small molecule inhibitors with various levels of success at inhibiting viral entry, increasing the potential of effective antiviral therapeutic development.

Abstract
Virus entry depends on biomolecular recognition at the surface of cell membranes. In the case of glycolipid receptors, these events are expected to be influenced by how the glycan epitope close to the membrane is presented to the virus. This presentation of membrane-associated glycans is more restricted than that of glycans in solution, particularly because of orientational constraints imposed on the glycolipid through its lateral interactions with other membrane lipids and proteins. We have developed and employed a total internal reflection fluorescence microscopy-based binding assay and a scheme for molecular dynamics (MD) membrane simulations to investigate the consequences of various glycan presentation effects. The system studied was histo-blood group antigen (HBGA) epitopes of membrane-bound glycosphingolipids (GSLs) derived from small intestinal epithelium of humans (type 1 chain) and dogs (type 2 chain) interacting with GII.4 norovirus-like particles. Our experimental results showed strong binding to all lipid-linked type 1 chain HBGAs but no or only weak binding to the corresponding type 2 chain HBGAs. This is in contrast to results derived from STD experiments with free HBGAs in solution where binding was observed for Lewis x. The MD data suggest that the strong binding to type 1 chain glycolipids was due to the well-exposed (1,2)-linked α-l-Fucp and (1,4)-linked α-l-Fucp residues, while the weaker binding or lack of binding to type 2 chain HBGAs was due to the very restricted accessibility of the (1,3)-linked α-l-Fucp residue when the glycolipid is embedded in a phospholipid membrane. Our results not only contribute to a general understanding of protein-carbohydrate interactions on model membrane surfaces, particularly in the context of virus binding, but also suggest a possible role of human intestinal GSLs as potential receptors for norovirus uptake.

Abstract
Norovirus, the cause of winter vomiting disease, has emerged in recent years to be a major cause of sporadic and epidemic gastroenteritis worldwide. The virus has been estimated to cause >200,000 deaths each year in developing countries. Although the virus is highly contagious, volunteer and field studies have shown that a subset of individuals appears resistant to infections. A single nucleotide mutation (G428A) in the fucosyltransferase gene (FUT2) on chromosome 19 provides strong protection from infection in 20% of the white population. Histo-blood group ABO(H) antigens with terminal fucose are believed to function as receptors for human norovirus in the gastrointestinal tract, but also negatively charged potential receptors have been identified. Norovirus infection is a unique example where a single nucleotide mutation in a fucosyltransferase gene plays a crucial role in susceptibility to one of the most common viral diseases. This review discusses the role of host genetics and carbohydrate structures in susceptibility to winter vomiting disease.

Abstract
Enveloped viruses, which include many medically important viruses such as human immunodeficiency virus, influenza virus and hepatitis C virus, are intracellular parasites that acquire lipid envelopes from their host cells. Success of replication is intimately linked to their ability to hijack host cell mechanisms, particularly those related to membrane dynamics and lipid metabolism. Despite recent progress, our knowledge of lipid mediated virus-host interactions remains highly incomplete. In addition, diverse experimental systems are used to study different stages of virus replication thus complicating comparisons. This review aims to present a unifying view of the widely diverse strategies used by enveloped viruses at distinct stages of their replication cycles.

Abstract
Susceptibility to norovirus infection has been linked to secretor status. Norovirus virus-like particles (VLPs; 0- 20 microg/mL) from the Norwalk (GI.1) and Dijon (GII.4) strains were assayed for binding to H type 1 and Lewis a pentaglycosylceramides, incorporated in laterally fluid supported lipid bilayers. Binding kinetics was monitored in real time in 40 microL stationary reaction chambers, using quartz crystal microbalance with dissipation (QCM-D) monitoring. Both strains displayed binding only to H type 1 and not to Lewis a glycosphingolipids, typical for epithelial cells of susceptible and resistant individuals, respectively. This binding specificity was confirmed by VLPs binding to the two glycosphingolipids chromatographed on TLC-plates. Experiments using bilayers with mixtures of H type 1 and Lewis a, with the total glycosphingolipid concentration constant at 10 wt%, showed that binding was only dependent on H type 1 concentrations and identical to experiments without additional Lewis a. Both strains showed a threshold concentration of H type 1 below which no binding was observable. The threshold was one order of magnitude higher for the Dijon strain (2 wt% versus 0.25 wt%) demonstrating that the interaction with a significantly larger number of glycosphingolipids was needed for the binding of the Dijon strain. The difference in threshold glycosphingolipid concentrations for the two strains suggests a lower affinity for the glycosphingolipid for the Dijon compared to the Norwalk strain. We propose that VLPs initially bind only a few glycosphingolipids but the binding is subsequently strengthened by lateral diffusion of additional glycosphingolipids moving into the interaction area.

Abstract
Sialic acid-containing compounds play a key role in the initial steps of the paramyxovirus life cycle. As enveloped viruses, their entry into the host cell consists of two main events: binding to the host cell and membrane fusion. Virus adsorption occurs at the surface of the host cell with the recognition of specific receptor molecules located at the cell membrane by specific viral attachment proteins. The viral attachment protein present in some paramyxoviruses (Respirovirus, Rubulavirus and Avulavirus) is the HN glycoprotein, which binds to cellular sialic acid-containing molecules and exhibits sialidase and fusion promotion activities. Gangliosides of the gangliotetraose series bearing the sialic acid N-acetylneuraminic (Neu5Ac) on the terminal galactose attached in alpha2-3 linkage, such as GD1a, GT1b, and GQ1b, and neolacto-series gangliosides are the major receptors for Sendai virus. Much less is known about the receptors for other paramyxoviruses than for Sendai virus. Human parainfluenza viruses 1 and 3 preferentially recognize oligosaccharides containing N-acetyllactosaminoglycan branches with terminal Neu5Acalpha2-3Gal. In the case of Newcastle disease virus, has been reported the absence of a specific pattern of the gangliosides that interact with the virus. Additionally, several works have described the use of sialylated glycoproteins as paramyxovirus receptors. Accordingly, the design of specific sialic acid analogs to inhibit the sialidase and/or receptor binding activity of viral attachment proteins is an important antiviral strategy. In spite of all these data, the exact nature of paramyxovirus receptors, apart from their sialylated nature, and the mechanism(s) of viral attachment to the cell surface are poorly understood.

Abstract
Differences in glycolipid expression between species contribute to the tropism of many infectious pathogens for their hosts. For example, we demonstrate that cultured human and monkey urinary epithelial cells fail to bind a canine Escherichia coli uropathogenic isolate; however, transfection of these cells with the canine Forssman synthetase (FS) cDNA enables abundant adherence by the same pathogen, indicating that addition of a single sugar residue to a glycolipid receptor has marked effects on microbial attachment. Given the contribution of glycolipids to host-microbial interactions, we sought to determine why human tissues do not express Forssman glycolipid. Query of the GenBank(TM) data base yielded a human sequence with high identity to the canine FS cDNA. Reverse transcription polymerase chain reaction and Northern blotting demonstrated the presence of FS mRNA in all tissues examined. A human FS cDNA was characterized, revealing identities with the canine FS gene of 86 and 83% at the nucleotide and predicted amino acid sequences, respectively. In contrast to the canine FS cDNA, transfection of COS-1 cells with the human FS cDNA resulted in no detectable FS enzyme activity. These results suggest that variability in glycolipid synthesis between species is an important determinant of microbial tropism. Evolutionary pressure from pathogenic organisms may have contributed to diversity in glycolipid expression among species.

Abstract
Helicobacterpylori, the ulcer pathogen residing in the human stomach, binds to epithelial cells of the gastric antrum. We have examined binding of 13 bacterial isolates to epithelial cell lines by use of a sensitive microtiter plate method in which measurement of bacterial urease activity provides the means for quantitation of bound organisms. Several established human gastrointestinal carcinoma cell lines grown as monolayers were compared for suitability in these assays, and the duodenum-derived cell line HuTu-80 was selected for testing bacterial binding inhibitors. When bacteria are pretreated with oligosaccharides, glycoproteins, and glycolipids, a complex picture of bacterial-epithelial adherence specificities emerges. Among the monovalent inhibitors tested, 3'-sialyllactose (NeuAc alpha2-3Gal beta1-4Glc; 3'SL) was the most active oligosaccharide, inhibiting adherence for recent clinical isolates of H. pylori with a millimolar 50% inhibitory concentration (IC50). Its alpha2-6 isomer (6'SL) was less active. Most of the recent clinical isolates examined were inhibited by sialyllactose, whereas long-passaged isolates were insensitive. Among the long-passaged bacterial strains whose binding was not inhibited by 3'SL was the strain ATCC 43504, also known as NCTC 11637 and CCUG 17874, in which the proposed sialyllactose adhesin was recently reported to lack surface expression (P. G. O'Toole, L. Janzon, P. Doig, J. Huang, M. Kostrzynska, and T. H. Trust, J. Bacteriol. 177:6049-6057, 1995). Pretreatment of the epithelial monolayer with neuraminidase reduced the extent of binding by those bacteria that are sensitive to inhibition by 3'SL. Other potent inhibitors of bacterial binding are the glycoproteins alpha1-acid glycoprotein, fetuin, porcine gastric and bovine submaxillary mucins, and the glycolipid sulfatide, all of which present multivalent sialylated and/or sulfated galactosyl residues under the conditions of the binding assay. Consistent with this pattern, a multivalent neoglycoconjugate containing 20 mol of 3'SL per mol of human serum albumin inhibited bacterial binding with micromolar IC50. The H. pylori isolate most sensitive to inhibition by 3'SL was least sensitive to inhibition by sulfatide, gastric mucin, and other sulfated oligosaccharides. Bacteria that have been allowed to bind epithelial cells are also effectively detached by 3'SL. These results describe a heterogeneous adherence repertoire for these bacteria, but they also confirm the critical role of the 3'SL structure on human gastric epithelial cells as an adherence ligand for recent isolates of H. pylori.

Abstract
Influenza A and Sendai viruses are known to bind to various extent to neolacto-series gangliosides IV3Neu5Ac-nLcOse4Cer, IV6Neu5Ac-nLcOse4Cer, and VI3Neu5Ac-nLcOse6Cer, which are the dominant gangliosides of human granulocytes. Recently, minor gangliosides of granulocytes were characterized and found to express sialyl Lewis(x) and VIM-2 epitopes. These long chain linear monosialogangliosides with nLcOse8, and nLcOse10, cores, carrying one to three fucoses, are shown in this study to bind with strong avidity to influenza A/PR/8/34 (H1N1), A/X-31 (H3N2), and Sendai virus (Z-strain) using the overlay technique. These and recent data from other groups imply that selectins and virus hemagglutinins are capable of competing with lipid bound sialyl Lewis(x) and VIM-2 epitopes on myeloid cells during inflammatory reactions.

Abstract
In this review an updated overview of current improvements on thin-layer chromatography (TLC) of gangliosides over the past decade is provided. Basic general techniques and special advice is given for successful separation of glycosphingolipids. New approaches concerning continuous and multiple development, and several preparative TLC methods are also included. Emphasis is placed on TLC immunostaining and related techniques, i.e. practical applications of carbohydrate-specific antibodies, toxins and bacteria, viruses, lectins and eukaryotic cells. Thus, this review on ganglioside TLC summarizes its power as an analytical tool for a wide range of purposes.

Abstract
Influenza A and Sendai viruses bind to neolacto-series gangliosides isolated from human granulocytes. Differences in receptor specificity of influenza viruses A/PR/8/34 (H1N1), A/X-31 (H3N2), and parainfluenza Sendai virus (HNF1, Z-strain) were determined by two direct solid phase binding assays: the overlay technique, which combines high-resolution in the separation of gangliosides on thin-layer chromatograms with direct binding; and the microwell adsorption assay as a convenient binding assay which is performed in microtitre wells to estimate the avidity of binding to an isolated ganglioside. Both methods were applied for comparative binding studies. Viruses were found to exhibit specificity for oligosaccharides and sialic acids as well as for chain length of the neutral carbohydrate backbone, whereas differing fatty acids (C24:1 and C16:0) in the ceramide portion had no impact on virus adsorption. Terminal sialyloligosaccharides Neu5Ac alpha 2-3Gal beta 1-4Glc-R of GM3, and Neu5Ac alpha 2-3Gal beta 1-4GlcNAc-R as well as Neu5Ac alpha 2-6Gal beta 1-4GlcNAc-R of neolacto-series gangliosides with nLcOse4Cer and nLcOse6Cer backbone, exhibited significant specific receptor activity towards the different viruses. To compare the data revealed from both test systems, values of virus binding were ascertained by a non-parametric statistical approach based on rank correlation. The rank correlation coefficient rs was calculated according to Spearman from each virus binding towards GM3, IV3Neu5Ac-nLcOse4Cer, IV6Neu5Ac-nLcOse4Cer and VI3Neu5Ac-nLcOse6SCer. The rank correlation coefficients 0.74, 0.95 and 0.92, which were determined for A/PR/8/34 (H1N1), A/X-31 (H3N2) and Sendai virus (HNF1, Z-strain), respectively, indicated that both assays generate highly correlated experimental data.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Previous studies from our laboratory have demonstrated the presence of a specific interaction between myelin-associated neuraminidase and GM1 (Saito and Yu, J Neurochem 47:632-641, 1986). In the present study, we further characterized this neuraminidase-GM1 interaction and examined its role in the adhesion of rat oligodendroglial cells to GM1. Hydrolysis of N-acetylneuramin-lactitol by the enzyme was inhibited by GM1 in a competitive manner; GM1 itself was not hydrolyzed, suggesting that GM1 may serve as a competitive inhibitor of the enzyme. Asialo-GM1 had no inhibitory effect. When a soluble enzyme preparation was applied to a GM1-linked affinity column, the enzyme activity was retained on the column and was recovered from the column only by elution with a buffer containing 5 mM 2,3-dehydro-2-deoxy-N-acetylneuraminic acid (Neu2en5Ac), a competitive inhibitor of neuraminidase. A binding study with 51Cr-labeled rat oligodendroglial cells showed that oligodendroglial cells bound preferentially to GM1 developed on a thin-layer plate, but not to other gangliosides such as GM3, GD1a, GD1b, and GT1b. The binding reaction to GM1 was inhibited by Neu2en5Ac (5 mM). These results suggest that myelin-associated neuraminidase specifically interacts with GM1 and may be involved in adhesion of oligodendroglial cells to GM1. This neuraminidase-GM1 interaction may play an important role in the formation and stabilization of the multilamellar structure of the myelin sheath.

Abstract
The structures of gangliosides from human granulocytes were elucidated by fast atom bombardment mass spectrometry and by gas chromatography/mass spectrometry as their partially methylated alditol acetates. In human granulocytes besides GM3 (II3Neu5Ac-LacCer), neolacto-series gangliosides (IV3Neu5Ac-nLcOse4Cer, IV6Neu5Ac-nLcOse4Cer and VI3Neu5Ac-nLcOse6Cer) containing C24:1, and to some extent C22:0; and C16:0 fatty acid in their respective ceramide portions, were identified as major components. In this study we demonstrate that gangliosides from human granulocytes, the second most abundant cells in peripheral blood, can serve as receptors for influenza viruses A/PR/8/34 (H1N1), A/X-31 (H3N2), and a parainfluenza virus Sendai virus (HNF1, Z-strain). Viruses were found to exhibit specific adhesion to terminal Neu5Ac alpha 2-3Gal and/or Neu5Ac alpha 2-6Gal sequences as well as depending on the chain length of ganglioside carbohydrate backbones from human granulocytes, these important effector cells which represent the first line of defence in immunologically mediated reactions.

Abstract
Rotaviral binding to receptors on epithelial cells in the small intestine is thought to be a key event in the infection process and may be carbohydrate-mediated. Strain SA11 of rotavirus bound in vitro both to glycolipids isolated from mouse small intestine and to authentic glycolipids using thin layer chromatography overlay and microtiter well adsorption assays. Neutral mouse intestinal glycolipids which bound rotavirus were GA1 (Gal beta 1----3GalNAc beta 1---4Glc beta 1----4Glc beta 1----1-ceramide) and pentaosylceramides with terminal N-acetylgalactosamine, while acidic lipids which bound rotavirus included cholesterol 3-sulfate and two compounds termed bands 80 and 81. Digestion with ceramide glycanase suggested that bands 80 and 81 have lactosyl ceramide cores and an unidentified acidic moiety(s). No sialic-acid-containing glycolipids tested were active in viral binding. Band 81, which may have a ganglio core, bound rotavirus with greatest avidity, followed by GA1. Of authentic glycolipids assayed, only GA1 and GA2 (GalNAc beta 1----4Gal beta 1----4Glc beta 1----1-ceramide) displayed rotaviral binding. A phosphatidylethanolamide dipalmitoyl-containing neoglycolipid analog of GA2 bound rotavirus with avidity similar to native GA2. Substitution of beta 1----4-linked GlcNAc or beta 1----3-linked GalNAc for terminal GalNAc of GA2 neoglycolipid supported rotaviral binding, while other substitutions abrogated it. These findings suggest that a carbohydrate epitope similar to that of GA2 is sufficient for in vitro rotaviral binding, although binding may be enhanced by galactose and/or an acidic moiety in a secondary epitope.

Abstract
An improved binding assay for detection of ganglioside receptors for influenza A, B, and C viruses was developed. In this system, the virions bound to gangliosides that were developed on a silica gel thin-layer plate were detected by mouse monoclonal antibody against viral hemagglutinin and peroxidase-conjugated anti-mouse immunoglobin. No hydrolysis of the gangliosides by viral receptor-destroying enzyme was detected in the present condition. The reactivity of the viruses to gangliosides depended on the amount of developed gangliosides (10 pmols-10 nmols), the molecular species of sialic acid, and their sugar sequences. Human influenza A (PR/8/34), B (Lee/40), and C (Ann Arbor/1/50) viruses bound different receptor epitopes of sialo-sugar chains of gangliosides. The A/PR/8 virus bound most effectively to Neu5Ac-containing lacto-series gangliosides carrying type I and type II sugar chains, followed by ganglio-series and hematoside-series gangliosides. The A/PR/8 virus weakly bound to Neu5Ac alpha 2,6lactotetraosylceramide [IV6(Neu5Ac)Lc4Cer] and Neu5Ac alpha 2,6paragloboside [IV6(Neu5Ac)nLc4Cer] carrying Neu5Ac alpha 2,6Gal sequence, although their Neu5Ac alpha 2,3Gal derivatives were the most potent gangliosides tested. B/Lee/40 bound restrictively to IV6(Neu5Ac)Lc4Cer and IV6(Neu5Ac)nLc4Cer, which carry Neu5Ac alpha 2,6Gal sequence, and type I and type II lacto-series sugar chain, respectively. C/Ann Arbor/1/50 reacted only with 9-O-Ac-Neu5Ac-carrying sugar chains in all the gangliosides tested. This method also allowed the microanalysis of receptor gangliosides of unknown samples. ESK cells, sensitive to the influenza A viruses infection, expressed several kinds of receptor active gangliosides, while those from ESK-R cells, resistant to the virus infection, were undetectable.

Abstract
An overlay and a solid-phase assay are presented which allow the specific detection of 9-O-acetylated sialic acids on sialoglycoconjugates immobilized on microtiter plates, nitrocellulose or separated on thin-layer chromatograms. The assay takes advantage of two different biological properties of influenza C virus, its high-affinity binding to 9-O-acetylated sialic acids and its sialate 9-O-acetylesterase that is used for detection of bound virus with fluorogenic or chromogenic substrates. Though simple and rapid, the assay is highly sensitive with a detection limit of 65 fmol 9-O-acetylated sialic acid in 9-O-acetylated ganglioside GD1a. Influenza C virus is able to bind to a wide spectrum of sialoglycoconjugates like mucins, serum glycoproteins or gangliosides containing naturally or synthetically O-acetylated sialic acids. 9-O-Acetyl-N-glycoloylneuraminic acid can also function as a high-affinity receptor determinant for influenza C virus. While the acetyl ester at the 9 position is essential for virus binding in all cases, a 4-O-acetyl group is not recognized. In addition to alpha(2.3) or alpha(2.6) bonds, 9-O-acetyl-N-acetylneuraminic acid in alpha(2.8) linkage to N-acetylneuraminic acid is also functionally active.

Abstract
Using a specially designed, motorised t.l.c.-f.a.b.-m.s. probe with continuous desorption and scanning over a moving t.l.c. plate, it was shown that glycolipids with identical carbohydrate sequences were well resolved into molecular species with differences in long-chain base and fatty acid. There was no serious diffusion of the glycolipids into the matrix. The technique is demonstrated for sulphatides (one and two sugar residues) isolated from human kidney, GM3 ganglioside isolated from human malignant melanoma, and chemically modified gangliotetraosylceramide from mouse intestine. T.l.c.-f.a.b.m.s. is convenient for sequencing and composition analysis of receptor-active glycolipids, the biological activity of which can be monitored in parallel by overlay on the t.l.c. plate with proteins, viruses, bacteria, or animal cells.

Abstract
The unique glycoprotein of influenza C virus, designated hemagglutinin (HEF), exhibits three functions: hemagglutination, esterase activity, and fusion factor. As the virus uses 9-O-acetylated sialic acid as a high-affinity receptor determinant for attachment to cells, its binding activity was used to reveal O-acetylated sialic acid residues after polyacrylamide gel electrophoresis and transfer onto nitrocellulose sheets of proteins and thin-layer chromatography of lipids. The specificity of the binding for O-acetylated sialoglycoconjugates was investigated. Our results showed that influenza C virus could detect the different forms of the two murine glycophorins which are known to be O-acetylated sialoglycoconjugates. The virus also bound to O-acetylated gangliosides isolated from embryonic chicken brain such as purified O-acetylated NeuAc alpha (2-8)NeuAc alpha (2-8)NeuAc alpha (2-3)Gal beta (1-4)Glc beta (1-1)ceramide (GT3). The esterase activity of the HEF protein of influenza C virus was used to unmask the sialic acid. After its deacetylation by the virus enzyme, the O-acetylated GT3 was recognized by a monoclonal antibody which binds only to the nonacetylated derivative. The results presented here show that influenza C virus is a discriminating analytical probe for identifying O-acetylated sialoglycoconjugates directly after Western blotting of proteins and thin-layer chromatography of lipids, thus providing a new analytical tool.

Abstract
Rotaviruses are the major etiologic agents of severe diarrhea in children. Many rotaviruses encode a hemagglutinin which binds to sialic acids. We report that rotaviruses specifically recognize the neutral glycosphingolipid gangliotetraosylceramide (asialo-GM1 or GA1). GA1 resolved by thin-layer chromatography is bound by rotavirus, and binding is blocked by neutralizing rotavirus antiserum. Similar glycosphingolipid structures, such as globoside, gangliotriaosylceramide, and GA1 oxidized with galactose oxidase are ineffective in binding rotavirus. Other enteric viruses also specifically bind GA1. GA1 adsorbed to polystyrene beads inhibits rotavirus replication in vitro (as do anti-GA1 antibodies). The use of orally administered immobilized GA1 or anti-GA1 antibodies may prove useful in preventing or attenuating rotaviral and other enteric viral infections.

Abstract
A method is described whereby ganglioside GM1 can be quantitated directly on thin-layer chromatograms using cholera toxin subunit B conjugated to horseradish peroxidase and visualized with chloronaphthol. Overlay and color development were performed after separating gangliosides on nano-TLC plates, and fixing with polyisobutylmethacrylate. Absolute quantitation was realized using a Shimadzu CS-9000 integrating spectrodensitometer, scanning at 580 nm. A correlation coefficient of 0.98 was obtained in a linear range of detection from 10(-11) to 10(-16) moles. Statistical analysis revealed good reproducibility and over 99% of the added gangliosides remained with the chromatogram during all overlay and washing procedures. By comparison, standard chemical visualization by resorcinol-HCl was linear in the nanomole range with a detection limit of only 10(-10) moles. Since the carbohydrate portion of gangliosides immobilized in this manner is susceptible to the action of enzymes including neuraminidase, this technique can be applied to all structures of the gangliotetraose series.

Abstract
The most common receptors for microbes on animal cells seem to be carbohydrates. One characteristic property of microbial protein-carbohydrate interaction is the recognition of sequences placed within an oligosaccharide chain. This leads to a series of isoreceptors defined as saccharides carrying the particular receptor sequence with different neighbouring groups. A microbial ligand may have different binding affinities for such isoreceptors depending upon steric hindrance from neighbouring groups upon access to the binding epitope. By a comparison of binding preferences to a series of isoreceptors with their calculated conformation, the binding epitope on a particular receptor sequence may be approximated by use of molecular modelling. This approach is illustrated for two bacteria recognising lactosylceramide. The potential importance of the procedure for further developments including drug design is briefly discussed.

Abstract
Uropathogenic Escherichia coli strains designated as ONAP, based on their O negative A positive agglutination of human P1 erythrocytes, were shown to prefer the globo-A glycolipid as a receptor structure. The dependence on both the A terminal and the globoseries chain was confirmed by agglutination of human AP1, but not Ap or OP1 erythrocytes and by binding to the globo-A glycolipid on TLC plates. Neither Gal alpha 1----4Gal beta nor the A trisaccharide GalNAc alpha 1----3(Fuc alpha 1----2)Gal beta alone functioned as receptors. The bacteria thus appeared to recognize an epitope resulting from the combination of the terminal and internal structures.

Abstract
Two species of Propionibacterium were analysed regarding their binding to glycosphingolipids. Bacteria were labeled with 125I and selective interaction with glycolipids on thin-layer chromatograms was revealed by autoradiography. The carbohydrate site in common for active molecular species appeared to be lactose. The two bacteria differed, however, in the overall binding pattern on the chromatogram, probably due to recognition of separate epitopes on lactose. P. freudenreichii bound only to lactosylceramide while P. granulosum also recognized substituted lactosylceramide: Gal alpha 1----3Gal beta 1----4Glc beta Cer, GlcNAc beta 1----3Gal beta 1----4Glc beta Cer and Gal beta 1----3GlcNAc beta 1----3Gal beta 1----4Glc beta Cer were active, but Gal-alpha 1----4Gal beta 1----4Glc beta Cer was inactive. Also, there was an interesting dependence on ceramide structure in the case of lactosylceramide. P. freudenreichii bound to lactosylceramide with sphingosine and non-hydroxy fatty acids but not to species with sphingosine and 2-hydroxy fatty acids, phytosphingosine and non-hydroxy fatty acids or phytosphingosine and 2-hydroxy fatty acids. For P. granulosum the situation was reversed. This may be explained by an influence of ceramide structure on the presentation of the two lactose epitopes at the assay surface. These results were supported by curves from the binding of labeled bacteria to glycolipids coated in microtiter wells and in part by binding to glycolipid-coated chicken erythrocytes.

Abstract
An overview and perspective is presented on animal cell surface carbohydrate (primarily lipid-linked oligosaccharides) as specific receptors for viruses, bacteria and bacterial toxins. Although carbohydrate has been known for many years to be specific attachment sites for these ligands, it is only in very recent time that carbohydrate technology and receptor assays in combination afford a rational approach. One generalization from present experience is the property of microbiological ligands to recognize sequences placed internally in an oligosaccharide chain which differs from antibody recognition of short sequences which most often involves terminally placed determinants. This is of both biological and technical importance. Biologically it may assure attachment by avoiding differences between host individuals often residing in terminal parts (e.g. blood group determinants), and may also make a shift of target cells by mutations more efficient. Technically this property is an important help when dissecting narrow binding epitopes, and for disclosing receptor-binding variants with only slight differences in binding epitopes (e.g. different epitopes on the same disaccharide). Such variants representing a kind of "epitope drift" are probably a consequence of point mutations in the binding site of the lectin-like proteins to select a proper host environment. Current technology allows an efficient screening for carbohydrate receptors with interesting consequences for applications within medicine (diagnosis and therapy) and biotechnology.

Abstract
A technique is described for direct detection by lectins conjugated to horseradish peroxidase of the oligosaccharides of glycosphingolipids on thin-layer chromatograms. Final visualization is accomplished using a substrate medium consisting of hydrogen peroxide and 3,3'-diaminobenzidine. The procedure is rapid, specific, sensitive and highly reproducible, and staining patterns are stable for years. In addition to providing preliminary structural information, this technique can be employed in combination with other methods, such as autoradiographic detection of tritium-labeled glycosphingolipids in the same chromatogram.

Abstract
Cell surface carbohydrates and complementary carbohydrate receptors may mediate cell-cell recognition and adhesion. We report a method which detects carbohydrate-specific adhesion of intact eukaryotic cells directly to glycosphingolipids separated on thin-layer chromatography plates. Various glycosphingolipids were chromatographed on high-performance silica gel thin-layer chromatography plates, and the plates were coated with a thin film of poly(isobutyl methacrylate) and mounted in a specially designed plexiglass chamber. Metabolically radiolabeled cells were added to the chamber, which was then sealed and gently centrifuged to bring the cells into contact with the surface of the TLC plate. After incubation to allow adhesion to occur, the chamber was inverted and centrifuged to remove nonadherent cells from the plate surface. The plate was removed from the chamber, the adherent cells were fixed in place with glutaraldehyde, and the plate was dried and subjected to autoradiography. Chicken hepatocytes, which have a cell surface receptor for N-acetylglucosamine, adhered only to those areas of the plate to which appropriate glycosphingolipids (having that terminal sugar) had migrated. Cell adhesion was blocked by soluble N-acetylglucosamine (but not by other sugars) and was readily detectable using a variety of developing solvents. Cell adhesion to as little as 8 pmol of the appropriate lipid was readily detected. This method can be used to test glycosphingolipids as cell surface recognition markers for a variety of cell types.

Abstract
The type 2 fimbrial lectin of Actinomyces naeslundii WVU45 mediated the binding of this bacterium to glycosphingolipids chromatographed on thin-layer silica gel plates. Radioiodinated bacteria attached to GM1, GD1b, and globoside. After chromatograms were treated with sialidase, the bacteria also bound to GD1a and GT1b. The actinomyces lectin apparently recognized the Gal beta 3GalNAc termini of these gangliosides and the GalNAc beta 3Gal terminus of globoside, suggesting that glycolipids containing these sequences may serve as receptors for A. naeslundii on mammalian cells.

Abstract
The abundance of carbohydrate at the animal cell surface may explain why microbes have selected primarily carbohydrates as essential attachment sites for colonization or infection. Of the various surface glycoconjugates of interest, primary attention has been given to glycolipids, due in part to an efficient binding assay based on a thin-layer chromatogram with separated glycolipids. In this way the general character of carbohydrate recognition by microbes is being mapped. Mainly two examples are briefly described to illustrate some generalizations: lactosylceramide-recognition by several bacteria, and Gal alpha l----4Gal-binding by Escherichia coli and the Shiga toxin. The unique recognition of internally placed sequences, the often low-affinity binding, and the preference of certain sequences before others are interpreted to be of decisive biological value. The binding to internal parts makes it technically possible to approximate the binding epitope on a receptor glycolipid. For this the binding preferences to glycolipids carrying the binding site in different saccharide environments (isoreceptors) are compared with the computer-calculated preferred conformations (definition of steric hindrances to epitope access). Several binding epitopes dissected with this approach have a common surface character: a nonpolar area of ring hydrogens over one or two sugars, surrounded by polar oxygens or amide. This is in agreement with the recent Lemieux concept for antibody-carbohydrate interaction. This information facilitates a rational synthesis of receptor analogues for potential applications. An outline is finally given of an improved general approach for receptor analysis.

Abstract
Sulfatides (galactosyl ceramide-I3-sulfate) and other sulfated glycolipids are found in many tissues. The cell adhesion proteins laminin, thrombospondin, and von Willebrand factor bind specifically to sulfated glycolipids. Methods for characterizing the specificity of these interactions using surface-adsorbed glycolipids are reviewed. The three proteins do not bind to other anionic lipids, including gangliosides, phospholipids, or cholesterol 3-sulfate. Binding to sulfatides is saturable and of relatively high affinity. Relative binding avidity depends on the oligosaccharide structure of the glycolipids. Binding to sulfatides in erythrocyte membranes can account for the hemagglutinating activities of the three proteins and may play a role in the interactions of these proteins with other cell types.

Abstract
Receptors for Sendai virions in human erythrocyte ghost membranes were identified by virus overlay of protein blots. Among the various erythrocyte polypeptides, only glycophorin was able to bind Sendai virions effectively. The detection of Sendai virions bound to glycophorin was accomplished either by employing anti-Sendai virus antibodies or by autoradiography, when 125I-labeled Sendai virions were used. The binding activity was associated with the viral hemagglutinin/neuraminidase (HN) glycoprotein, as inferred from the observation that the binding pattern of purified HN glycoprotein to human erythrocyte membranes was identical to that of intact Sendai virions. No binding was observed when blots, containing either human erythrocyte membranes or purified glycophorin, were probed with the viral fusion factor (F glycoprotein). Active virions competed effectively with the binding of 125I-labeled Sendai virions (or purified HN glycoprotein), whereas no competition was observed with inactivated Sendai virus. The results of the present work clearly show that protein blotting can be used to identify virus receptors in cell membrane preparations.

Abstract
The hypothesis tested was that a particular glycoconjugate(s) in the exposed cell-surface membrane of susceptible insect cells acts as a receptor and/or modulator for the specific interaction with the protoxin/activated toxin of the delta-endotoxin of Bacillus thuringiensis var. kurstaki. As candidates, the total neutral and acidic fraction glycolipids, and the isolated neutral glycosphingolipid components, were screened for binding activity by the thin layer chromatogram overlay technique. The main protoxin/activated toxin-binding glycolipid in the neutral fraction (5B) had the structure: Gal(alpha 1-3)GalNAc(beta 1-4)GlcNAc(beta 1-3)Man(beta 1-4)Glc(beta 1-1)Cer. The main protoxin/activated toxin-binding glycolipid in the acidic fraction was designated band 1, the structure of which is at present unknown. The possibility that the component 5B carbohydrate sequence may also function as a toxin-binding site of relevant insect plasma membrane glycoproteins is discussed.

Abstract
This report describes the construction of neoglycolipids as a novel approach to determining the antigenicities and receptor functions of minute amounts of oligosaccharides derived from glycoproteins. Reduced oligosaccharides are converted into oligosaccharide alditols by controlled selective periodate oxidation and conjugated to phosphatidyl ethanolamine dipalmitoyl by reductive amination. The resulting neoglycolipids can be rendered multivalent by binding to polyvinylchloride or silica plates or they can be incorporated into liposomes and their antigenicities and receptor activities determined in low concentrations by direct binding or inhibition of binding assays. This approach, which has been successfully used with two monoclonal antibodies and a plant lectin, should be widely applicable to the direct analysis of O- and N-glycosidically linked carbohydrate chains of glycoproteins and proteoglycans both as antigens and recognition structures of diverse receptor systems.

Abstract
Six monoclonal antibodies with known specificities for the carbohydrate antigens i, X or Y, and seven anti-myeloid antibodies (determinants unknown) selected for their differing reaction patterns with human leucocytes were tested in chromatogram binding assays for reactions with myeloid cell glycolipids derived from normal human granulocytes and chronic myelogenous leukemia cells. Antigenicities were found exclusively on minor glycolipids which were barely or not at all detectable with orcinol-sulphuric acid stain. Among these, a neutral glycosphingolipid bound the anti-i antibody Den and chromatographed as the ceramide octasaccharide, Gal beta 1----4GlcNac beta 1----3Gal beta 1----4GlcNac beta 1----3Gal beta 1----4GlcNAc beta 1----3Gal beta 1----4Glc-Cer. Several species of neutral glycosphingolipids with six to more than ten monosaccharides were detected which carry the X antigen and others the Y antigen: Gal beta 1----4(Fuc alpha 1----3)GlcNAc and Fuc alpha 1----2Gal beta 1----4(Fuc alpha 1----3)GlcNAc, respectively. In addition, three new types of carbohydrate specificities were detected among the myeloid cell glycolipids. Two were associated with neutral glycolipids: the first, recognised by anti-myeloid antibodies VIM-1 and VIM-10, was expressed on a distinct set of glycolipids with six or more monosaccharides, and the second, recognized by VIM-8, was expressed on glycolipids with more than ten monosaccharides. The third specificity, recognised by the anti-myeloid antibody VIM-2, was expressed on slow migrating sialoglycolipids with backbone structures of the poly-N-acetyllactosamine type that are susceptible to degradation with endo-beta-galactosidase. Thus, we conclude that the i and Y antigens occur among the glycolipids of normal myeloid and chronic myelogenous leukemia cells and that a high proportion of hybridoma antibodies raised against differentiation antigens of myeloid cells are directed at carbohydrate structures.
