  1. 1. Helicobacter pylori : molecular mechanisms for variable adherence properties

    Författare :Anna Vallström; Anna Arnqvist; Kristian Riesbeck; Umeå universitet; []
    Nyckelord :H. pylori; adherence; BabA; SabA; Leb; sLex; phase variation; recombination; vesicles;

    Sammanfattning : More than half of all people worldwide are infected with H. pylori. The infection always cause a gastric inflammation that may develop into peptic ulcer disease or gastric cancer. Attachment proteins, adhesins, mediate specific adherence of H. LÄS MER

  3. 2. Recombinant mucin-type proteins as tools for studies on the interactions between Helicobacter pylori and its carbohydrate receptors

    Författare :Yolanda H. Mthembu; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; O-glycans; mucins; glycosyltransferases; Helicobacter pylori; microbial adhesion;

    Sammanfattning : Glycan-protein interactions are important in pathogen adhesion and infections. H. pylori has adhesins which enables it to bind to glycans on the gastric mucosa and, in the long run, cause gastric cancer. The reported current antibiotic regimen used in the treatment to eradicate H. LÄS MER

  4. 3. Helicobacter pylori : multitalented adaptation of binding properties

    Författare :Sara Henriksson; Thomas Borén; Göran Larson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter pylori; adherence; receptor specificity; adaptation; pH; BabA; Leb; recombination; secretor phenotype; recombinant cell lines;

    Sammanfattning : Helicobacter pylori infects and persistently colonizes the stomach, which results in gastritis and in some individuals peptic ulcer disease or gastric cancer. Adherence of H. pylori to the epithelium is an important factor for development of disease. LÄS MER

  5. 4. Helicobacter pylori : molecular insights into regulation of adhesion properties

    Författare :Pär Gideonsson; Anna Arnqvist; Thomas Borén; Hilde De Reuse; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter pylori; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : Helicobacter pylori infects the human stomach and triggers an inflammatory response that damages the gastric tissue. This host-pathogen interplay has dire consequences as up to 20 % of infected individuals develop peptic ulcer disease or gastric cancer. LÄS MER

  7. 5. Helicobacter pylori : bacterial adhesion and host response

    Författare :Farzad Olfat; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Communicable diseases; Infektionssjukdomar; Infectious diseases; Infektionssjukdomar;

    Sammanfattning : The gastric pathogen Helicobacter pylori infects more than half of the population worldwide. H. pylori manage to establish persistent infection, which would be life-long if not treated. In order to establish such an infection, this pathogen has to deal with the host immune system. LÄS MER
