  1. 1. Citrobacter rodentium and Escherichia coli interactions with mucus producing colonic epithelical cells

    Författare :Sinan Sharba; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; A E pathogens; cytokines; epithelium; mitochondria; mucus;

    Sammanfattning : The epithelial cells together with the mucus layer protect the host from noxious luminal substances and pathogenic invasion. Pathogens have evolved numerous strategies to circumvent these barriers and mount infection. C. rodentium is a murine model for the attaching and effacing intestinal E. LÄS MER

  3. 2. Microcirculation, Mucus and Microbiota in Inflammatory Bowel Disease

    Författare :Olof Schreiber; Lena Holm; Mia Phillipson; Henrik Sjövall; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; inflammatory bowel diseases; experimental colitis; DSS; TNBS; colonic mucosal blood flow; laser-doppler flowmetry; colonic mucus thickness; MUC2; colonic mucosal barrier function; iNOS; eNOS; probiotics; Lactobacilli; Lactobacillus reuteri; colonic microbiota; T-RFLP; bacterial translocation; intravital microscopy; P-selectin; leukocyte recruitment; platelet recruitment; Physiology; Fysiologi; Physiology; Fysiologi;

    Sammanfattning : Inflammatory bowel diseases, (IBD), are a group of chronic disorders of the gastro-intestinal tract, and include Crohn’s disease (CD) and Ulcerative Colitis (UC). The pathogenesis is not known, but involves at least in part a loss of tolerance towards the commensal colonic microbiota. LÄS MER

  4. 3. Understanding the gastrointestinal mucus and its impact on drug absorption

    Författare :Vicky Barmpatsalou; Christel Bergström; Eva Karlsson; Betty Lomstein Pedersen; Hanne Mørck Nielsen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mucus; gastrointestinal; pigs; dogs; physiology; colonic; in vitro assay; drug diffusion; macromolecules;

    Sammanfattning : The gastrointestinal mucus is a hydrogel lining the luminal side of the gastrointestinal epithelium. Mucus is vital for gut homeostasis because it protects the epithelium from the noxious external environment. LÄS MER

  5. 4. Colonic mucus structure and processing

    Författare :Elisabeth E. L. Nyström; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mucus; CLCA1; Goblet cell; Spdef;

    Sammanfattning : The mucus layer covering the colonic epithelium creates a crucial first line of defense against the gut residing bacteria. Several lines of evidence suggest that a functional mucus layer is essential for health. For example, it is. suggested that ulcerative colitis is correlated with mucus layer defects. LÄS MER

  7. 5. 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. LÄS MER
