  1. 1. Perturbation of the epithelial barrier by enteric pathogens

    Författare :Farideh Tafazoli; Magnusson Karl-Eric; Hakon Leffler; Linköpings universitet; []
    Nyckelord :enteric pathogens: signal transduction; barrier function; MEDICINE; MEDICIN;

    Sammanfattning : Gastrointestinal infections in humans have been associated with a number of diseased condition, including stomach ulcers, gastroenteritis, Crohn's disease, and rheumatic arthritis. Such infections often cause altered intestinal permeability through perturbation of the tight junctions that hold epithelial cells together. LÄS MER

  2. 2. The intestinal epithelium of salmonids : transepithelial transport, barrier function and bacterial interactions

    Författare :Fredrik Jutfelt; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Epithelial barrier function; smoltification; cortisol; osmoregulation; Aeromonas salmonicida; Atlantic salmon; rainbow trout; bacterial translocation; intestine; Ussing chamber; vegetable lipids;

    Sammanfattning : The salmonid intestinal epithelium is important for growth and health of the fish. The epithelium is exposed to a multitude of internal and external factors that can influence its function. LÄS MER

  3. 3. Epithelial barrier dysfunction in ileal Crohn's disease

    Författare :Johan Dabrosin-Söderholm; Svante Nordgren; Linköpings universitet; []
    Nyckelord :acetylsalicylic add; confocal microscopy; Crohn s disease; cytoskeleton; electron microscopy; genetics; human; ileum; inflammatory bowel disease; intestinal absorption; intestinal mucosa; macromolecules; mitochondria; ovalbumin; permeability; sodium caprate; tight junctions; transcytosis; uncoupling agents; Ussing chamber; MEDICINE; MEDICIN;

    Sammanfattning : The study aimed at investigating the intestinal barrier in Crohn's disease, with special reference to epithelial responses to luminal stimuli, and to permeation of proteins.Ileal mucosa from patients undergoing intestinal resection was studied in vitro in Ussing chambers.

  4. 4. Intestinal barrier function in health and disease

    Författare :Pernilla Nejdfors; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; VIP.; PACAP; secretion; ion transport; urine reservoir; radiation therapy; ulcerative colitis; macromolecules; dextran; mannitol; Ussing chamber; Intestinal permeability; mucosa; Animal physiology; Djurfysiologi; Physiology; Fysiologi;

    Sammanfattning : The intestinal epithelium has the dual function of absorbing nutrients and water as well as being a barrier to potentially harmful substances such as macromolecules and bacteria. In the present thesis the barrier function of the intestinal mucosa was studied in vitro in Ussing diffusion chambers. LÄS MER

  5. 5. Genetic and molecular regulation of epithelial tube morphogenesis

    Författare :Anna Tonning; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :epithelial tube morphogenesis; trachea; Drosophila; chitin; chitin synthase; apical extracellular matrix; paracellular diffusion barrier; tube expansion; septate junctions;

    Sammanfattning : Networks of epithelial tubes, such as the vertebrate lung, kidney and vascular system, enable transport of gases and nutrients to all tissues in the body. These tubes are built up by a single layer of polarized epithelial cells, with the apical membrane facing the lumen. LÄS MER
