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

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

    Sammanfattning : 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. LÄS MER

  3. 17. Adaptation of Helicobacter pylori Adherence Properties in Promotion of Host Tropism and Inflammatory Disease

    Författare :Marina Aspholm; Rino Rappuoli; Umeå universitet; []
    Nyckelord :H. pylori; BabA; SabA; adhesin; blood group antigens; sialylated; phase variation; hemagglutination; selectin; adaptation; odontologi; Odontology;

    Sammanfattning : Being among the most prevalent of persistent infectious agents in humans worldwide, Helicobacter pylori induces chronic inflammation (gastritis), which may progress to peptic ulceration and stomach cancer. The ability to adhere to the gastric mucosa is considered to be both a colonization and virulence property of H. pylori. For adherence, H. LÄS MER

  4. 18. Electrical impedance related to experimental induced changes of human skin and oral mucosa

    Författare :Ingrid Nicander; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :bioengineering; dielectric properties; electrical impedance; irritation; non-invasive; oral mucosa; skin; skin barrier; stratum comeum; stratum corneum lipids;

    Sammanfattning : There is a need for an objective and non-invasive method for assessing reactions in the human skin and oral mucosa, particularly for weak reactions. During the past few decades, several methods of measuring irritant responses have indeed been developed for the skin and to some extent also for the oral mucosa. LÄS MER

  5. 19. Langerhans cells in oral mucosa and skin. A functional and morphological study

    Författare :Bengt Hasséus; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Langerhans cells (LC) are a subpopulation of dendritic cells residing in skin and mucosal epi-thelium. LC capture antigens in the periphery and following migration to regional lymph nodes present peptides to T cells. LCs have a central role in initiating a T cell mediated immune re-sponse, both in health and disease. LÄS MER

  7. 20. Invariant T cell subsets in immune defense of oral mucosa and skin

    Författare :Michał J Sobkowiak; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Innate-like T lymphocytes such as mucosa-associated invariant T (MAIT) cells and invariant natural killer T (iNKT) cells recognize antigens presented by MR1 and CD1d molecules, respectively. As MR1 presents microbial riboflavin metabolite antigens, and CD1d presents endogenous or microbial glycolipid antigens, MAIT cells and iNKT cells survey the non-protein fraction of the potential antigenic universe.
