| Abstract |
The core oligosaccharides of Campylobacter jejuni lipopolysaccharides
(LPS) display molecular mimicry with gangliosides. Cross-reactive
anti-LPS-antiganglioside antibodies have been implicated to show a crucial
role in the pathogenesis of the Guillain-Barre and Miller Fisher syndrome.
The specificity of the antiganglioside response is thought to depend on
the oligosaccharide structure of the ganglioside mimic. To test this
hypothesis and to investigate the potential of LPS from Campylobacter
strains from enteritis patients to induce an antiganglioside response, we
immunized rabbits with purified LPS from eight Campylobacter jejuni
reference strains with biochemically well-defined distinct ganglioside
mimics and determined the presence of antiganglioside antibodies. All
rabbits produced immunoglobulin G (IgM) and IgG anti-LPS antibodies, and
the specificity of the cross-reactive antiganglioside response indeed
corresponded with the biochemically defined mimic. Most rabbits also had
antibody reactivity against additional gangliosides, and there were slight
differences in the fine specificity of the antibody response between
rabbits that had been immunized with LPS from the same Campylobacter
strain. High anti-LPS and antiganglioside titers persisted over a 10-month
period. In conclusion, the structure of the LPS only partly determines the
antiganglioside specificity. Other strain-specific as well as host-related
factors influence the induction and fine-specificity of the cross-reactive
anti-LPS-antiganglioside response. |
