  1. 36. Helicobacter pylori associated effects on inflammatory radical formation and angiotensin II receptors in the stomach

    Författare :Anders Elfvin; Göteborgs universitet; []
    Nyckelord :Helicobacter pylori; Mongolian gerbil; gastric adenocarcinoma; nitro-radical; iNOS; nitric oxide; nitrotyrosine; oxy-radical; myeloperoxidase; angiotensin II; AT1R; AT2R;

    Sammanfattning : Helicobacter pylori infection of the stomach always results in mucosal inflammation and a marked systemic immune response. Despite the profound host defence reactions the bacterium avoids elimination and persists in the mucosa. This results in chronic inflammation and an increased risk for peptic ulcers and adenocarcinoma. LÄS MER

  3. 37. Innate lymphocyte responses in inflammatory diseases

    Författare :Johanna Emgård; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The immune system is a highly sophisticated system that has evolved to protect the host from external and internal threats. However, under some circumstances the immune response can get dysregulated and cause inflammatory diseases. LÄS MER

  4. 38. Vaginal commensal bacteria. Interactions with cervix epithelial and monocytic cells and influence on cytokines and secretory leukocyte protease inhibitor, SLPI

    Författare :Louise Strömbeck; Göteborgs universitet; []
    Nyckelord :Prevotella bivia; bacterial vaginosis BV ; invasion; Lactobacillus; secretory leukocyte protease inhibitor SLPI ; cytokines; THP-1; HeLa cells;

    Sammanfattning : Vaginal commensal bacteria Interactions with cervix epithelial and monocytic cells and influence on cytokines and secretory leukocyte protease inhibitor, SLPI Louise Strömbeck Department of Infectious Medicine, Gothenburg University Abstract Lactobacillus is the predominant species of the vaginal microbiota in women of childbearing age. Lactobacilli are thought to contribute to the local immune defence by producing a variety of antimicrobial substances and, thereby, attenuate growth of other opportunistic bacteria. LÄS MER

  5. 39. Signalling and activation of TLR4 by Gram-negative bacteria in epithelial cells

    Författare :Lisa Meijer; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Lipopolysaccharide (LPS) is a well-characterized pathogen-associated molecule found primarily as a constituent of the outer membrane of Gram-negative bacteria. LPS is known to act on different cell types in a pleiotropic manner. LÄS MER

  7. 40. Lactobacilli- and Staphylococcus aureus mediated modulation of immune responses in vitro

    Författare :Yeneneh Haileselassie; Eva Sverremark-Ekström; Huub Savelkoul; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lactobacilli; staphylococcus aureus; dendritic cells; retinoic acid; epithelial cells; T cells; immunologi; Immunology;

    Sammanfattning : The human gut harbors a vast number of microbes. These microbes are not passive bystanders. They are important in modulating the immune system. We have previously shown that early colonization with lactobacilli and Staphylococcus (S. LÄS MER
