    Sammanfattning : Crohns sjukdom är en kronisk inflammatorisk tarmsjukdom av okänd orsak. Det tidigaste tecknet på Crohns sjukdom är mikroskopiska sår i det s.k. follikelassocierade epitelet (FAE) som täcker ansamlingar av immunceller i tarmen. LÄS MER

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

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

    Sammanfattning : 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. 3. Starch Microparticles as an Oral Vaccine Adjuvant with Emphasis on the Differentiation of the Immune Response

    Författare :Linda Stertman; Ingvar Sjöholm; Kjell-Olov Grönvik; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; Vaccine adjuvant; Microparticles; Oral immunisation; Th1 Th2 differentiation; Mucosal immune response; Uptake; M cell; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

    Sammanfattning : Polyacryl starch microparticles have been developed as an oral vaccine adjuvant capable of inducing strong local and systemic immune responses in mice. In this thesis, the starch microparticles were studied in order to increase basic understanding of their function. LÄS MER

  5. 4. Deciphering cell motility and spatial sensing of intestinal cell types using an ex vivo intestinal model

    Författare :Anna Webb; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The intestine is a highly organized tissue with two distinct regions: the crypt and the villus. When stem cells divide at the crypt bottom, half of their progeny migrates upwards towards the villus, where they differentiate into various cell types, including the abundant absorptive enterocytes.
