  2. 6. Cholera toxin B subunit as a carrier for inducing mucosal immunity and/or peripheral tolerance

    Author : Carola Rask; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mucosal immunity; tolerance; atopic allergy; cholera toxin B subunit; antibody response; IgE;

    Abstract : When an antigen is introduced via a mucosal route, either immunity or tolerance, or even both may be induced. Both immunity and tolerance are actively induced phenomena and both of them could have important medical implications as well as potential prophylactic or therapeutic applications. READ MORE

  4. 7. Incidence trends and environmental determinants of type 1 diabetes in Lithuania and Sweden

    Author : Auste Pundziute-Lyckå; Gisela Dahlquist; Brone Urbonaite; Hans Kristian Åkerblom; Umeå universitet; []

  5. 8. Mechanisms of immune escape : implications for immunotherapy against cancer

    Author : Karl-Johan Malmberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Tumor Immunology; Immune escape; NK receptors; T lymphocytes; Oxidative stress; Vitamin E;

    Abstract : Tumor cells can be recognized and killed by cytotoxic T cells specific for certain tumor antigens. Immune mediated selection pressure along with genetic instability of tumor cells result in a growth advantage of tumor cells that acquire a less immunogenic phenotype. READ MORE

  6. 9. Beyond Th1 and Treg : intestinal T helper cells in disease and tolerance

    Author : Rebeca Franco Cardoso; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The human intestinal tract is not only one of the largest organs by surface area in our bodies but also harbors the greatest number of immune cells. These cells are crucial for maintaining tolerance towards the various food and microbial antigens and mounting protective inflammatory responses towards invading pathogens. READ MORE

  7. 10. The ontogeny and function of intestinal dendritic cells

    Author : Emma Persson; Slemhinnans immunologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mesenteric lymph nodes; Intestine; Dendritic cells; Gut-homing; Th17 cells; Oral tolerance; Immunity;

    Abstract : The intestinal mucosa presents a huge surface area to the external environment and the intestinal immune system is continually exposed to a wide array of foreign antigens derived from resident intestinal microbiota as well as dietary constituents, including food proteins. In order to maintain intestinal homeostasis, the intestinal immune system relies on the ability to generate tolerogenic responses to innocuous antigen while maintaining the ability to develop effective immune responses to intesinal pathogens.
