  1. 21. 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. 22. Phenotype and function of intestinal CD103+ dendritic cells

    Författare :Elin Jaensson Gyllenbäck; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CD103; dendritic cell; CX3CR1; small intestine; MLN; CCR9; Vitamin A; retinoic acid;

    Sammanfattning : Mucosal tissues such as the intestine present an enormous surface area to the outside environment and are continually exposed to foreign antigens in food and microflora. Thus, the intestinal mucosa must must remain tolerant to these innocuous antigens while at same time be able to mount effective immune responses to pathogens. LÄS MER

  4. 23. 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.

  5. 24. Intestinal mucins 'soluble and insoluble problems'

    Författare :Annkatrin Herrmann; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; colorectal carcinoma; pulse labelling; organ culture; glycopeptide; small intestine; colon; glycoprotein complex; insoluble; muc2; MUC2; Mucin; mucus; carbohydrate; oligosaccharide.; Gastro-enterology; Gastroenterologi;

    Sammanfattning : Highly glycosylated glycoproteins – mucins – are the major constituents of the mucus layer and glycocalyx that cover mucosal surfaces. Twelve human mucin genes have been identified, and the mucins may be divided into those that are membraneassociated and those that are secreted. LÄS MER

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

    Författare :Claes Hjalmarsson; Malmö Institutionen för kliniska vetenskaper; []

    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
