Infection and Immunity 65(10) (1997) 4038-4042
Seven patients with Miller Fisher syndrome (MFS), six in the acute phase and one in the recovery phase, were investigated for serum antibodies against gangliosides and purified lipopolysaccharides (LPS) from different strains of Campylobacter jejuni, including the MFS-associated serotypes O:2 and O:23. Immunoglobulin G antibodies against gangliosides GT1a and GQ1b were found in five of six patients in the acute phase of disease. Three of these patients also displayed antibodies to ganglioside GD2, a finding not previously reported for MFS. All anti-GT1a- and anti-GQ1b-seropositive patients showed antibody binding to C. jejuni LPS, predominantly to O:2 and O:23 LPS. Antibody cross-reactivity between gangliosides GT1a and GQ1b and O:2 and O:23 LPS was demonstrated by adsorption studies. This cross-reactivity between gangliosides and C.jejuni LPS, which is obviously due to oligosaccharide homologies, may be an important pathogenetic factor in the development of MFS after C. jejuni infection

Annals of Neurology 37 (1995) 260-264
Three patients who had diarrhea prior to the development of Miller Fisher syndrome are presented. Campylobacter jejuni was isolated from stool specimens from all patients. High titers of anti-GQ1b IgG antibodies were demonstrated in the serum of these patients by enzyme-linked immunosorbent assay and thin-layer chromatography overlay. In enzyme-linked immunosorbent assay inhibition studies the anti-GQ1b IgG antibodies bound specifically to whole bacteria of the Miller Fisher syndrome-associated C. jejuni strains. The presence of anti-GQ1b IgG binding epitopes on the surface of the C. jejuni from the patients was not exclusively associated with a specific Penner serotype. It is suggested that anti-GQ1b antibodies are formed during the initial infection that elicits Miller Fisher syndrome. The cross-reactivity of anti-GQ1b IgG antibodies with surface epitopes on Miller Fisher syndrome-associated C. jejuni strains supports the hypothesis of molecular mimicry between bacteria and neural tissue.

Biomedical Research (India) 13 (1992) 451-453
We investigated the lipopolysaccharide (LPS) from Penner's serotype 19 (PEN 19) of C. jejuni that had been isolated from a patient with the Guillain-Barre syndrome (GBS). The LPS was extracted from the bacterium and separated by a silica beads column chromatography. One homogeneous fraction showing reactivity with the patient's serum, rabbit anti-G(M1) antibody, and also with cholera toxin, which binds oligosaccharide of G(M1), was obtained. By gas-liquid chromatography-mass spectrometric analysis, the purified LPS was found to contain D-galactose, D-glucose, N-acetyl-D-galactosamine, N-acetyl-D-glucosamine, N-acetylneuraminic acid; 3-deoxy-2-octulosonic acid, heptose and fatty acids (3-hydroxy-myristic acid and palmitic acid). The result indicates that sugar components of the G(M1)-oligosaccharide are present in the purified LPS. Chemical analysis and immunological binding experiment show that the LPS from C. jejuni (PEN 19) has the oligosaccharide structure in common with G(M1) ganglioside. These results suggest that some GBS patients associated with anti-G(M1), antibody are caused by an autoimmune mechanism after infection by C.jejuni (PEN 19) which has the G(M1)-oligosaccharide structure.

Hoppe-Seyler's Zeitschrift fur Physiologische Chemie [German] 359 (1978) 1277-1286
The stimulation by cholera toxin of adenylate cyclase in Chinese hamster ovarian cells could be inhibited by various ligands. The latter have been shown to contain the structural oligosaccharide entities required for binding to cholera toxin, established as Galβ1→3GalNAcβ1→4Gal3 comes from 2αNeuAc. The different inhibitory potency of the ligands thereby correlates with the size of the aggregates formed with the toxin, which in turn depends on the valency of the ligands. The conclusion is drawn from a comparison of the interaction of cholera toxin and its B-protomer with ganglioside II3NeuAc-GgOse4-Cer, the newly synthesized bis-(monosialo-gangliotetraityl)amine and monosialogangliotetraose. In a double diffusion test cholera toxin B-protomer precipitated with the ganglioside II3 NeuAcGgOSE4-Cer and the divalent ligand bis(monosialo-gangliotetraityl)amine, suggesting the formation of high molecular weight aggregates, whereas no precipitation was observed with the monovalent monosialo-gangliotetraose. By ultracentrifugation analysis, aggregate formation of the cholera toxin B-protomer could be demonstrated with the ganglioside II3 NeuAc-GgOse4-Cer and bis(monosialo-gangliotetraityl)amine at a concentration at which the ganglioside was assumed to be monodisperse. Ganglioside/cholera toxin B-protomer complexes sediment faster than those of the toxin and bis(monosialo-gangliotetraityl)amine, suggesting higher aggregation of cholera toxin B-protomer with the former. On the other hand, no sedimentation with monosialo-gangliotetraose was observed. By equilibrium displacement dialysis, however, a comparable high affinity of binding to cholera toxin B-protomer of both the mono- and divalent oligosaccharides was demonstrated. Furthermore, values for the maximal concentration of the bound ligand from these binding experiments with cholera toxin B-protomer established molar ratios of ligand to protein of 4 to 1 and 2 to 1 for monosialo-gangliotetraose and bis(monosialo-gangliotetraityl)amine, respectively. From the results it is concluded that the lipophilic moiety of the ganglioside is not directly involved in the binding process to the toxin protein but leads to an oligovalency of this ligand, due to formation of micellar or submicellar structures.

Journal of the Neurological Sciences 130 (1995) 112-116
Sera from patients with Guillain-Barre syndrome (GBS) frequently have anti-GM1 antibody. We earlier showed that an lipopolysaccharides (LPS) from Campylobacter jejuni (PEN 19) isolated from a GBS patient has a GM1 ganglioside-like structure. Aspinall et al. (Biochemistry,61 (1994) 335-337) reported that OH 4382 has an LPS that bears a CD3 ganglioside-like structure and that OH 4384 has an LPS that bears a GT1a-like structure; both strains were isolated from patients with GBS. They also suggested a GM1-like structure is present in the LPSs from OH 4384, but failed to show the presence in the LPSs from OH 4382. To clarify the pathogenesis of GBS after infection by C. jejuni (PEN 19), we investigated the carbohydrate structures of the three strains by thin-layer chromatography immunostaining with cholera toxin and monoclonal anti-ganglioside antibodies. We found that both OH 4382 and OH 4384 have an LPS with the GM1 epitope as well as one with the GT1a or GD3 epitope.

(Biochemistry,61 (1994) 335-337) reported that OH 4382 has an LPS that bears a CD3 ganglioside-like structure and that OH 4384 has an LPS that bears a GT1a-like structure; both strains were isolated from patients with GBS. They also suggested a GM1-like structure is present in the LPSs from OH 4384, but failed to show the presence in the LPSs from OH 4382. To clarify the pathogenesis of GBS after infection by C. jejuni (PEN 19), we investigated the carbohydrate structures of the three strains by thin-layer chromatography immunostaining with cholera toxin and monoclonal anti-ganglioside antibodies. We found that both OH 4382 and OH 4384 have an LPS with the GM1 epitope as well as one with the GT1a or GD3 epitope.

Komagamine T, Yuki N "Ganglioside mimicry as a cause of Guillain-Barre syndrome" -
CNS and Neurological Disorders Drug Targets 5(4) (2006) 391-400
Guillain-Barre syndrome (GBS), characterized by acute progressive limb weakness and areflexia, is the prototype of postinfectious autoimmune diseases. Campylobacter jejuni is the most frequently identified agent of infection in GBS patients, often preceding acute motor axonal neuropathy (AMAN), a variant of GBS. Anti-GM1, anti-GM1b, anti-GD1a, and anti-GalNAc-GD1a IgG antibodies are associated with AMAN. Carbohydrate mimicry [Galβ1-3GalNAcβ1-4(NeuAcα2-3)Galβ1-] was seen between the lipo-oligosaccharide of C. jejuni isolated from an AMAN patient and human GM1 ganglioside. Sensitization with the lipo-oligosaccharide of C. jejuni induces AMAN in rabbits as does sensitization with GM1 ganglioside. Paralyzed rabbits have pathological changes in their peripheral nerves identical to changes seen in human GBS. C. jejuni infection may induce anti-ganglioside antibodies by molecular mimicry, eliciting AMAN. This is the first verification of the causative mechanism of molecular mimicry in an autoimmune disease. To express ganglioside mimics, C. jejuni requires specific gene combinations that function in sialic acid biosynthesis or transfer. The knockout mutants of these landmark genes of GBS show reduced reactivity with GBS patients' sera, and fail to induce an anti-ganglioside antibody response in mice. These genes are crucial for the induction of neuropathogenic cross-reactive antibodies. An approach for evaluating intravenous immune globulin, a treatment for GBS, based on our animal model of AMAN is also discussed in this review, and recent advances made in this field are described.

Moran A "The Role of Endotoxin in Infection: Helicobacter pylori and Campylobacter jejuni" -
Book: Endotoxins: Structure, Function and Recognition (series: Subcellular Biochemistry, Part 1) (2010) Vol. 53, Chapter 10, 209-240
Both Helicobacter pylori and Campylobacter jejuni are highly prevalent Gram-negative microaerophilic bacteria which are gastrointestinal pathogens of humans; H. pylori colonizes the gastroduodenal compartment and C. jejuni the intestinal mucosa. Although H. pylori causes chronic gastric infection leading to gastritis, peptic ulcers and eventually gastric cancer while C. jejuni causes acute infection inducing diarrhoeal disease, the endotoxin molecules of both bacterial species contrastingly contribute to their pathogenesis and the autoimmune sequelae each induces. Compared with enterobacterial endotoxin, that of H. pylori has significantly lower endotoxic and immuno-activities, the molecular basis for which is the underphosphorylation and underacylation of the lipid A component that interacts with immune receptors. This induction of low immunological responsiveness by endotoxin may aid the prolongation of H. pylori infection and therefore infection chronicity. On the other hand, this contrasts with acute infection-causing C. jejuni where overt inflammation contributes to pathology and diarrhoea production, and whose endotoxin is immunologically and endotoxically active. Futhermore, both H. pylori and C. jejuni exhibit molecular mimicry in the saccharide components of their endotoxins which can induce autoreactive antibodies; H. pylori expresses mimicry of Lewis and some ABO blood group antigens, C. jejuni mimicry of gangliosides. The former has been implicated in influencing the development of inflammation and gastric atrophy (a precursor of gastic cancer), the latter is central to the development of the neurological disorder Guillain-Barre syndrome. Both diseases raise important questions concerning infection-induced autoimmunity awaiting to be addressed.

Chemistry: a European Journal 25(3) (2019) 796-805
The chemical synthesis of the highly branched core oligosaccharides of lipooligosaccharides (LOSs) found in Campylobacter jejuni, which causes Guillain-Barré syndrome by a preceding infection, is described. The target LOS mimics, consisting of eight or nine monosaccharides, were classified into three groups as key building blocks: ganglioside-core tetra-/pentasaccharides (GM1-/GD1a-like), l-glycero-d-manno-heptose-containing trisaccharides, and 3-deoxy-d-manno-2-octulosonic acid (KDO) residues. These synthetic fragments were obtained from commercially available monosaccharides. Less obtainable l-glycero-d-manno-heptose and KDO residues, as key components of the LOSs, were synthesized from p-methoxyphenyl d-mannoside and di-O-isopropylidene-protected d-mannose, respectively. The synthesis of α-KDO glycoside, as one of the most difficult stereocontrolled glycosidic constructions, was achieved by treating a 2,3-ene derivative of KDO with phenylselenyl trifluoromethanesulfonate as a suitable alpha-directing reagent. All synthetic blocks were constructed through a convergent synthetic route, which resulted in the first synthesis of structurally challenging LOS core glycans containing ganglioside GM1 and GD1a-core sequences.
