Structural Heterogeneity of Terminal Glycans in Campylobacter jejuni Lipooligosaccharides
Lipooligosaccharides of the gastrointestinal pathogen Campylobacter jejuni are regarded as a major virulence factor and are implicated in the production of cross-reactive antibodies against host gangliosides, which leads to the development of autoimmune neuropathies such as Guillain-Barré and Fisher Syndromes. C. jejuni strains are known to produce diverse LOS structures encoded by more than 19...
متن کاملCharacterization of the specific interaction between sialoadhesin and sialylated Campylobacter jejuni lipooligosaccharides.
In Campylobacter jejuni-induced Guillain-Barré syndrome (GBS), molecular mimicry between C. jejuni lipooligosaccharide (LOS) and host gangliosides leads to the production of cross-reactive antibodies directed against the peripheral nerves of the host. Currently, the presence of surface exposed sialylated LOS in C. jejuni is the single known bacterial pathogenesis factor associated with the deve...
متن کاملCampylobacter jejuni lipooligosaccharides modulate dendritic cell-mediated T cell polarization in a sialic acid linkage-dependent manner.
Carbohydrate mimicry between Campylobacter jejuni lipooligosaccharides (LOS) and host neural gangliosides plays a crucial role in the pathogenesis of Guillain-Barré syndrome (GBS). Campylobacter jejuni LOS may mimic various gangliosides, which affects the immunogenicity and the type of neurological deficits in GBS patients. Previous studies have shown the interaction of LOS with sialic acid-spe...
متن کاملGene expression profile of Campylobacter jejuni in response to growth temperature variation.
The foodborne pathogen Campylobacter jejuni is the primary causative agent of gastroenteritis in humans. In the present study a whole genome microarray of C. jejuni was constructed and validated. These DNA microarrays were used to measure changes in transcription levels over time, as C. jejuni cells responded to a temperature increase from 37 to 42 degrees C. Approximately 20% of the C. jejuni ...
متن کاملThe Role of Campylobacter Jejuni in Campylobacteriosis
Campylobacter jejuni is a Gram negative, curved, motile, thermophilic and microaerophilic bacillus in Campylobacteriaceae family, which is one of the main causes of enteritis in human named campylobacteriosis. The main reservoir of Campylobacter jejuni is the alimentary tract of animals, especially chicken and turkey. Consumption of semi-cooked chicken meat, raw milk and unchlorinated water are...
