    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter pylori; endothelial cells; neutrophils; monocytes; transendothelial; migration; chemokines; cytokines; adhesion molecules inflammation; LPS; CagPAI; VacA;

    Sammanfattning : Helicobacter pylori, a bacterium colonizing the human gastric mucosa, is strongly associatedwith the development of gastric and duodenal ulcers, as well as gastric, adenocarcinoma.Virtually all infected individuals develop active chronic gastritis characterized by a continousinfiltration of neutrophils as well as mononuclear cells.

  3. 12. Helicobacter pylori binding to gastric mucins and host glycosylation changes after inoculation

    Författare :Sara Lindén; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicinska vetenskaper allmänt ; General biomedical sciences; host-parasite interactions; H. pylori adhesin; mucin; Lewis antigen;

    Sammanfattning : Helicobacter pylori may cause gastritis, gastric/duodenal ulcer and gastric cancer. During infection, most H. pylori are found in the gastric mucus layer, but some are attached to, or have penetrated, epithelial cells. The aim of this study is to characterize the binding of H.

  4. 13. Approaches to analyses of cytotoxic cells. And studies of their role in H. pylori infection

    Författare :Josef Azem; Göteborgs universitet; []
    Nyckelord :Helicobacter pylori; mucosal immunology; stomach; duodenum; asymptomatic; duodenal ulcer; gastric adenocarcinoma; NK cells; T cells; B cells; dendritic cells; cytotoxic;

    Sammanfattning : Helicobacter pylori infection causes chronic gastritis that may progress to peptic ulcers or gastric adenocarcinoma and thereby cause major world-wide health problems. Previous studies have shown that CD4+ T cells and the production of the cytokine IFN- × are important components of the immune response to H. pylori in humans. LÄS MER

    Sammanfattning : The Helicobacter genus now consists of at least 26 species, with additional novel species in the process of being validated. Beyond the impact of H. LÄS MER

  7. 15. Helicobacter pylori infection and immunity. Protection after vaccination and regulation of inflammation in a mouse model

    Författare :Sukanya Raghavan; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter pylori; formalin-inactivated H. pylori; post-immunization gastritis; cholera toxin; CD4 CD25 regulatory T cells; CpG ODN;

    Sammanfattning : Helicobacter pylori infection is an important cause of chronic active gastritis and peptic ulcer disease and a risk factor for the development of gastric cancer. An attractive strategy in the control of H. pylori infection is the development of a safe and effective therapeutic vaccine. Using a mouse model of H. LÄS MER
