Structural studies on lipopolysaccharides of serologically non-typable strains of helicobacter pylori, af1 and 007, expressing lewis antigenic determinants
In contrast to other Helicobacter pylori strains, which have serologically detectable Lewis(x) (Le(x)) and Lewis(y) (Le(y)) antigenic determinants in the O-specific polysaccharide chains of the lipopolysaccharides, H. ...
Relationship of anti-lewis x and anti-lewis y antibodies in serum samples from gastric cancer and chronic gastritis patients to helicobacter pylori-mediated autoimmunity
(American Society for Microbiology, 2001-08-01)
Lewis (Le) antigens have been implicated in the pathogenesis of atrophic gastritis and gastric cancer in the setting of Helicobacter pylori infection, and H. pylori-induced anti-Le antibodies have been described that ...
Comparison of three serological methods for detection of lewis antigens on the surface of helicobacter pylori
(Oxford University Press (OUP), 2000-09-01)
Phenotypic variation in molecular mimicry betweenhelicobacter pylorilipopolysaccharides and human gastric epithelial cell surface glycoforms
(American Society for Biochemistry & Molecular Biology (ASBMB), 2001-12-07)
Helicobacter pylori is an important gastroduodenal pathogen of humans whose survival in the gastric environment below pH 4 is dependent on bacterial production of urease, whereas above pH 4 urease-independent mechanisms ...
Lipopolysaccharide structures of helicobacter pylori genomic strains 26695 and j99, mouse model h. pylori sydney strain, h. pylori p466 carrying sialyl lewis x, and h. pylori ua915 expressing lewis b
This study describes the molecular makeup of the cell-wall lipopolysaccharides (LPSs) (O-chain polysaccharide-->core oligosaccharide-->lipid A) from five Helicobacter pylori strains: H. pylori 26695 and J99, the ...
Simultaneous expression of type 1 and type 2 lewis blood group antigens byhelicobacter pylorilipopolysaccharides
(American Society for Biochemistry & Molecular Biology (ASBMB), 1998-05-08)
Previous structural investigations performed on the lipopolysaccharides (LPSs) from the human gastric pathogen Helicobacter pylori have revealed that these cell surface glycan molecules express type 2 partially fucosylated, ...
Structural characterization of the lipid a component of helicobacter pylori rough- and smooth-form lipopolysaccharides.
(American Society for Microbiology, 1997-10-01)
The chemical structure of free lipid A isolated from rough-and smooth-form lipopolysaccharides (R-LPS and S-LPS, respectively) of the human gastroduodenal pathogen Helicobacter pylori was elucidated by compositional and ...
