Structural studies on lipopolysaccharides of serologically non-typable strains of helicobacter pylori, af1 and 007, expressing lewis antigenic determinants
(Wiley-Blackwell, 1999-11-15)
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)
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
(Wiley-Blackwell, 2000-01-01)
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 ...
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 ...
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 ...
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, ...
