  1. 6. Butyrophilin- and Butyrophilin-like genes and their role in epithelial cell-intraepithelial T lymphocyte cross-talk

    Författare :Cristina Lebrero-Fernandez; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Butyrophilin-like Btnl ; Butyrophilin Btn ; Intraepithelial lymphocytes IELs ; Mucosal immunity; Intestinal epithelial cells; γδ T cells; Intestinal inflammation; Colon cancer; Ulcerative colitis;

    Sammanfattning : More than 50% of our immune system is located in the gut. The intestinal epithelium, which forms an interface between the organism and the environment, harbors intraepithelial lymphocytes (IELs) that comprise a mixture of conventional αβ T cells and unconventional αβ- and γδ T cells.

  3. 7. Signalling and trafficking of the cysteinyl leukotriene receptors in intestinal epithelial cells

    Författare :Ladan Parhamifar; Malmö Cellpatologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; trafficking; Cysteinyl leukotriene receptors; inflammation; cytosolic phospholipase A2; colon cancer;

    Sammanfattning : Inflammation is a response to injury or pathogen invasion. A large proportion of the bodie's immune system is centred in the gastrointestinal tract (GI). Prolonged inflammatory conditions of the GI have been suggested to increase the risk for developing colon cancer. LÄS MER

  4. 8. Staphylococcus aureus alpha-toxin : natural fragments and effects on intestinal epithelial cells

    Författare :Young-Keun Kwak; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Staphylococcus aureus is a human pathogen, commonly found in healthy humans as a part of normal flora. alpha-toxin is thought to be largely responsible for the pathogenesis of the bacterium. LÄS MER

  5. 9. Specific and nonspecific immune mechanisms in human gut : a comparative study of normal and ulcerative colitis intestine

    Författare :Moorix Mo-Wai Yeung; Sten Hammarström; Marie-Louise Hammarström; Marita Troye-Blomberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human intestine; ulcerative colitis; lymphoid aggregates; intraepithelial lymphocytes; lamina propria lymphocytes; γδT-cells; cytokines; IL-2; carcinoembryonic antigen; biliary glycoprotein; epithelial cells; glycocalyx;

    Sammanfattning : The intestine, with its large mucosal surface area, digests and absorbs food nutrients and maintains a beneficial microbial flora in the colon. Local protective immune responses against intestinal pathogens ensure the survival of the individual. These immune reactions are both specific and non-specific in nature. LÄS MER

  7. 10. 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
