  2. 11. Matrix metalloproteinases in Helicobacter inducedgastritis

    Author : Philip Bergin; Göteborgs universitet; []
    Keywords : Helicobacter pylori; Helicobacter felis; Matrix metalloproteinase; macrophage; ; Gastritis;

    Abstract : Helicobacter pylori infects the stomach and areas of gastric metaplasia in the duodenum. Theinfection leads to peptic ulcers or gastric cancers in 10-20% of infected individuals, while themajority are more or less asymptomatic. However, active chronic gastritis develops in all infectedindividuals, often in association with atrophic gastritis. READ MORE

    Author : Siiri Hirmo; Enheten för infektionssjukdomar; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bakteriologi; mycology; Mikrobiologi; virology; bacteriology; haemagglutinin; Helicobacter pylori; sialic acid; sialidase; gastrointestinal mucin; milk glycoprotein; Microbiology; resonant mirror biosensor; virologi; mykologi;

    Abstract : Helicobacter pylori is a gastric pathogen colonising the gastric mucus layer and epithelium of gastric tissue and is associated with chronic type B gastritis and peptic ulcer disease. The attachment of H. pylori to gastric epithelial cells involves several structures recognised by specific bacterial surface proteins. READ MORE

  5. 13. T lymphocyte recruitment in Helicobacter pylori-associated diseases

    Author : Karin Enarsson; Göteborgs universitet; []
    Keywords : Helicobacter pylori; homing; T lymphocytes; gastric adenocarcinoma; regulatory T cells;

    Abstract : Helicobacter pylori (Hp) infection is associated with pronounced infiltration of granulocytes and lymphocytes into the gastric mucosa, resulting in active chronic gastritis that may develop into duodenal ulcer disease or gastric adenocarcinoma (GC). Infiltrating T cells play a major role in the pathology of these diseases, but the signals involved in recruitment of T cells from blood to H. READ MORE

  6. 14. Helicobacter pylori adhesion and patho-adaptation : the role of BabA and SabA adhesins in persistent infection and chronic inflammation

    Author : Jafar Mahdavi; Henrik Clausen; Umeå universitet; []
    Keywords : H. pylori; BabA; adhesin; Lewis b; MUC5AC; sialyl-dimeric-Lewis x; chronic inflammation; SabA; Lewis x; LPS; odontologi; Odontology;

    Abstract : Helicobacter pylori (H. pylori) is a human-specific gastric pathogen which is responsible for a spectrum of diseases ranging from superficial gastritis to gastric and duodenal ulceration, and which is also highly associated with gastric cancer. The pathogenesis of severe gastric disorders caused by H. READ MORE

  7. 15. Aspects of Helicobacter pylori transmission

    Author : Mårten Kivi; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Helicobacter pylori; epidemiology; transmission; family; two-stage; missing data; molecular typing; CagA; cag pathogenicity island; variability; microarray;

    Abstract : The bacterium Helicobacter pylori infects the gastric mucosa of about half of the world's population. The infection causes gastritis and contributes to the development of peptic ulcer disease and gastric cancer. H. READ MORE
