  2. 1. Paracellular permeability of intestinal epithelia.An in vivo study

    Author : Britt-Marie Fihn; Göteborgs universitet; []
    Keywords : paracellular permeability; intestinal epithelia; deoxycholic acid; cholera toxin; glucose absorption; water transport;

    Abstract : Aim: Investigate the importance of paracellular transport of water and solutes during physiological and pathophysiological conditions. Methods: The transport of small water-soluble inert permeability markers, was studied in jejunum and colon in anesthetized rats and cats during normal conditions and during exposure to cholera toxin (CT) and deoxycholic acid (DCA).

  4. 2. Analysis of epithelial electrophysiological function in paediatric intestinal biopsies

    Author : Annika Reims; Göteborgs universitet; []
    Keywords : Cystic fibrosis; CFTR; coeliac disease; Ussing chamber; intestinal permeability; ion transport; leukotriene; human; duodenum;

    Abstract : Intestinal biopsies are routinely taken from children under investigation of failure to thrive, diarrhoea, abdominal pain and/or malnutrition. These biopsies are usually only evaluated morphologically, i.e. no information is collected with regard to mucosal function. READ MORE

  5. 3. Alterations of mucin O-glycosylation in response to intestinal infection. Importance of specific glycosyltransferases

    Author : Fredrik J. Olson; Göteborgs universitet; []
    Keywords : mucins; altered O-glycosylation; Nippostrongylus brasiliensis infection; blood group A glycosyltransferase; Muc2; MUC1; GalNAc-T4; mass spectrometry;

    Abstract : Mucins are large glycoproteins constituting the major protein component of the mucus layer covering the epithelial surfaces. The mucins are characterised by a dense and heterogeneous O-glycosylation, important for their chemical and physiological properties. READ MORE

  6. 4. Role of antimicrobial peptides in combating shigellosis and in antibiotic-associated diarrhea

    Author : Protim Sarker; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Antimicrobial peptides (AMPs) constitute front-line components of innate immunity in multicellular organisms. AMPs are able to kill a wide range of pathogens and exhibit additional important functions such as chemotaxis, angiogenesis and wound healing. These peptides are constitutively expressed in immune and/or epithelial cells. READ MORE

  7. 5. Studies of Vibrio cholerae toxins (zonula occludens toxin and hemagglutinin/protease) and their effects on epithelial cells

    Author : Zhengyang Wu; Åsa Ljung; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Intestinal epithelium is important for absorption of nutrients and for defense against harmful substances in the gut. The permeability and barrier functions of epithelia are mainly controlled by intercellular tight junctions. READ MORE
