    Description: The near-germline antibody S25-2 exhibits a remarkable cross-reactivity for oligosaccharides containing the bacterial lipopolysaccharide carbohydrate 3-deoxy-D- manno -oct-2-ulosonic acid (Kdo). The recent synthesis of a variety of Kdo analogues permits a detailed structural analysis of the importance of specific interactions in antigen recognition by S25-2. The Kdo disaccharide analogue Kdo-(2→4)-5,6-dehydro-Kdo lacks a 5-OH group on the second Kdo residue and has been cocrystallized with S25-2. The structure reveals that the modification of the Kdo residue at position 5 results in a rearrangement of intramolecular hydrogen bonds in the antigen that allows it to assume a novel conformation in the antibody-combining site. The cross-reactive binding of S25-2 to this synthetic ligand highlights the adaptability of this antibody to non-natural synthetic analogues.

    Notes: Salmonella infections in naturally susceptible mice grow rapidly, with death occurring only after bacterial numbers in vivo have reached a high threshold level, commonly called the lethal load. Despite much speculation, no direct evidence has been available to substantiate a role for any candidate bacterial components in causing death. One of the most likely candidates for the lethal toxin in salmonellosis is endotoxin, specifically the lipid A domain of the lipopolysaccharide (LPS) molecule. Consequently, we have constructed a Salmonella mutant with a deletion–insertion in its waaN gene, which encodes the enzyme that catalyses one of the two secondary acylation reactions that complete lipid A biosynthesis. The mutant biosynthesizes a lipid A molecule lacking a single fatty acyl chain and is consequently less able to induce cytokine and inducible nitric oxide synthase (iNOS) responses both in vivo and in vitro. The mutant bacteria appear healthy, are not sensitive to increased growth temperature and synthesize a full-length O-antigen-containing LPS molecule lacking only the expected secondary acyl chain. On intravenous inoculation into susceptible BALB/c mice, wild-type salmonellae grew at the expected rate of approximately 10-fold per day in livers and spleens and caused the death of the infected mice when lethal loads of approximately 108 were attained in these organs. Somewhat unexpectedly, waaN mutant bacteria grew at exactly the same rate as wild-type bacteria in BALB/c mice but, when counts reached 108 per organ, mice infected with mutant bacteria survived. Bacterial growth continued until unprecedentedly high counts of 109 per organ were attained, when approximately 10% of the mice died. Most of the animals carrying these high bacterial loads survived, and the bacteria were slowly cleared from the organs. These experiments provide the first direct evidence that death in a mouse typhoid infection is directly dependent on the toxicity of lipid A and suggest that this may be mediated via pro-inflammatory cytokine and/or iNOS responses.

    Notes: The gene kdtA of Chlamydia pneumoniae strain TW-183, encoding the enzyme 3-deoxy-α-d-manno-octulosonic acid (Kdo)transferase of lipopolysaccharide biosynthesis, was cloned and sequenced. A single open reading frame of 1314 bp was identified, the deduced amino acid sequence of which revealed 69% similarity and 43% identity with KdtA of Chlamydia trachomatis and Chlamydia psittaci. The gene was expressed in the Gram-positive host Corynebacterium glutamicum and the primary gene product was characterized as a multi-functional glycosyltransferase. Cell-free extracts generated in vitro the genus-specific epitope of Chlamydia composed of the trisaccharide (αKdo(2–8)αKdo(2–4)αKdo. The results show that a single polypeptide affords three different glycosidic bonds, which is in contradiction to the dogma of glycobiology: ‘one enzyme — one glycosidic bond’.

    Notes: We have investigated the function of the lsi-1 gene of Neisseria gonorrhoeae previously implicated in lipopolysaccharide (LPS)-inner-core biosynthesis (Petricoin et al., 1991). Disruption of the gene in gonococcal strain MS11 resulted in the production of LPS that migrated faster than that from an isogenic galE mutant, typical for a mutation that influences the inner-core region. Complementation of a panel of Salmonella typhimurium mutants with defined defects in rfa loci demonstrated conclusively that the lsi-1 gene of MS11 is functionally homologous to the rfaF gene, which encodes heptosyltransferase II in both E. coli and S. typhimurium. Comparison of deduced amino acid sequences of the gonococcal and the Salmonella RfaF demonstrated 70% similarity, including 47% identical amino acid residues. Immunochemical analysis of the LPS using monoclonal antibodies directed against chemically defined inner-core glycoconjugates revealed that the gonococcal and Salmonella Rd2-Chemotypes were antigenically similar, further extending the genetic and functional homology. Infection experiments in vitro demonstrated that the lsi-1 mutant could not invade human Chang epithelial cells despite expression of a genetically defined invasion-promoting gonococcal opacity protein. These data imply that the LPS phenotype is a critical factor for gonococcal invasiveness.

    Notes: Monoclonal antibodies against the lipopolysaccharide (LPS) of the deep rough mutant I-69 Rd−/b+ of Haemophilus influenzae were obtained after immunization of mice with sheep erythrocytes which had been coated with de-O-acylated LPS. Characterization of antibodies was performed by enzyme immuno assay (EIA) using LPS or neoglycoconjugates containing partial structures of LPS as solid-phase antigens and by haemagglutination with sheep erythrocytes coated with de-O-acylated LPS. Binding data were confirmed by EIA inhibition experiments using deacylated LPS or synthetic partial structures thereof. Three antibodies were specific for 3-deoxy-d-manno-octulopyranosonic acid- (Kdo) 5-phosphate, one for Kdo-4-phosphate, and one required, in addition to a Kdo-phosphate, parts of the phosphorylated glucosamine backbone of lipid A. All antibodies also bound in (i) Western blots to bacterial whole-cell lysates or isolated LPS separated by SDS–PAGE, (ii) bacterial colony blots, and (iii) immunofluorescence with live bacteria. The latter result indicated that Kdo-4- and Kdo-5-phosphate are synthesized by the bacteria and are not the result of phosphate migration.

    Notes: [Auszug] Platelet-activating factor (PAF) induces pulmonary edema and has a key role in acute lung injury (ALI). Here we show that PAF induces pulmonary edema through two mechanisms: acid sphingomyelinase (ASM)-dependent production of ceramide, and activation of the cyclooxygenase pathway. Agents that ...

    Notes: The antigen-binding fragments (Fab) of two murine monoclonal antibodies (mAb) S25-2 and S45-18, specific for carbohydrate epitopes in the lipopolysacchaide of the bacterial family Chlamydiaceae, have been crystallized in the presence and absence of synthetic oligosaccharides corresponding to their respective haptens. Crystals of both Fabs show different morphology depending on the presence of antigens. The sequence of mAb S45-18 was determined and shows a remarkable homology to that reported for mAb S25-2. These crystals offer an unparalleled opportunity to compare the structure and modes of binding of two homologous antibodies to similar but distinct carbohydrate epitopes.
