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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

    Author : Johan Dabrosin-Söderholm; Svante Nordgren; Linköpings universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 4. Intestinal barrier function in health and disease

    Author : Pernilla Nejdfors; Biologiska institutionen; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE
