  1. 11. Regulation of T cell effector functions in the intestinal mucosa

    Författare :Petra Holmkvist; Slemhinnans immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; T cells; memory; intestine; cytokines; differentiation; IL-18; inflammation; antigen presentation;

    Sammanfattning : T lymphocytes are a critical cellular component of the adaptive immune response. They are generated in the thymus from bone marrow derived progenitors, where they undergo commitment to the T cell lineage and differentiate and mature into naïve CD4+ and CD8+ T cells. LÄS MER

  3. 12. Defence capabilities of human intestinal epithelial cells

    Författare :Anna Fahlgren; Sten Hammarström; Marie-Louise Hammarström; Gudmundur Gudmundsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; intestine; mucosa; epithelium; antimicrobial; defensins; glycocalyx; ulcerative colitis; Crohn´s disease; celiac disease; Immunologi; Immunology; Immunologi; immunologi; Immunology;

    Sammanfattning : The epithelial cells lining the intestinal mucosa separate the underlying tissue from components of the intestinal lumen. Innate immunity mediated by intestinal epithelial cells (IECs) provides rapid protective functions against microorganisms. Innate immunity also participates in orchestrating adaptive immunity.

  4. 13. Intestinal permeability : a parameter of mucosal dysfunction

    Författare :Pål Lundin; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Peptide; N-acetylcysteine; Medium-chain glyceride; Mannitol; Macromolecules; Lipid; Kinetics; In vivo; In vitro; In situ; Intestine; Injury; Inflammation; HLA-B27; HCl; Epithelium; Enhancer; dDAVP; 51Cr-EDTA; BSA; Absorption; Albumin; Permeability; Animal physiology; Djurfysiologi;

    Sammanfattning : The gastrointestinal tract has two opposing functions; to absorb nutrients and electrolytes, and to act as a barrier towards hazardous and non-nutritional substances. In the present thesis the barrier function of the gastrointestinal tract was studied in animal models in vivo, in situ and in vitro. LÄS MER

  5. 14. Intestinal IgA synthesis: Localization and requirements for IgA class switch recombination

    Författare :Peter Bergqvist; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IgA; Intestine; Gut associated lymphoid tissue; class switch recombination; CD40; germ free;

    Sammanfattning : Production of IgA at mucosal surfaces is one of the most striking features of the mucosal immune system. Despite that IgA was first discovered in the 1950’s and secretory IgA described in gut secretions and breast milk in the mid 1960’s we still have limited information about the sites and exact requirements for IgA class switch recombination.

  7. 15. Pancreatic Growth and Secretion. An Experimental Study on Growth Factors in Rat and Mouse

    Författare :Claes Hjalmarsson; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Cytology; PBD; insulin; B-cells; bile; pancreatic cancer; intestine; secretion; pancreas; proliferation; tyrphostins; CCK; epidermal growth factor; transforming growth factor alpha; cancerology; Cytologi; onkologi; cancer; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : The pancreas is a central organ in the digestion of food as well as in glucose metabolism. Its two major functions are exocrine and endocrine secretion. LÄS MER
