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

    Författare :Cristina Lebrero-Fernandez; Göteborgs universitet.; Gothenburg University.; [2016]
    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.

  2. 2. Defence capabilities of human intestinal epithelial cells

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Anna Fahlgren; Umeå universitet.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; intestine; mucosa; epithelium; antimicrobial; defensins; glycocalyx; ulcerative colitis; Crohn´s disease; celiac disease; Immunologi; MEDICINE Microbiology; immunology; infectious diseases Immunology; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar 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.

  3. 3. Human intestinal epithelial cells in innate immunity interactions with normal microbiota and pathogenic bacteria

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Gangwei Ou; Umeå universitet.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; immunologi; Immunology;

    Sammanfattning : Rod-shaped bacteria were previously shown to be associated with the small intestinal epithelium of children with celiac disease (CD). Using culture-dependent and independent methods, we characterized the microbiota of small intestine in children with CD and controls. The normal microbiota constitutes an unique organ-specific biofilm. LÄS MER

  4. 4. Lactobacilli- and Staphylococcus aureus mediated modulation of immune responses in vitro

    Detta är en avhandling från Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University

    Författare :Yeneneh Haileselassie; Stockholms universitet.; [2016]
    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

  5. 5. Membrane transport and the human small intestine : Relation to mucosal protection, intestinal anaphylaxis and nitric oxide

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Tina W. Knutson; Uppsala universitet.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; albumin; bicarbonate secretion; carbonic anhydrase; dopamine; duodenum; histamine; humans; hyaluronan; intestinal anaphylaxis; intestinal obstruction; jejunum; lidocaine; LOC-I-GUT; nitecapone; nitric oxide; potential difference; prostaglandins; segmental intestinal perfusion; Kirurgi; MEDICINE Surgery; MEDICIN Kirurgi; anestesiologi; Anaesthesiology;

    Sammanfattning : The tightly adherent monolayer of epithelial cells that line the luminal side of the intestine provides a dynamic and highly regulated barrier to the passive and active transport of ions, water and macromolecules. Cathecol-O-methyl transferase inhibition prevents tissue degradation of catecholaminesincluding dopamine and intracellular carbonic anhydrase activity is an important regulator of ion and water transport in the small intestine.
