  1. 21. Role of mast cells and probiotics in the regulation of intestinal barrier function

    Författare :Anders Carlsson; Johan D. Söderholm; Åsa Keita; Karl-Eric Magnusson; Björn Weström; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The intestinal mucosa is the largest contact area and one of the most important barriers to the outside environment. It is highly specialized in aiding us digest and absorb nutrients. It is daily exposed to several potentially dangerous substances and microorganisms, which if they were allowed to pass into the body, could give rise to diseases. LÄS MER

  3. 22. Conséquences d’un stress chronique sur la barrière de mucus intestinal chez le rat : effet du probiotique Lactobacillus farciminis

    Författare :Stéphanie da Silva; Muriel Mercier-Bonin; Annick Bernadier-Donadille; Bruno Pot; Nathalie Juge; France Clermont Ferrand University UMR454 INRA; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background. Despite a large body of literature incriminating mucus alterations in the pathogenesis of Intestinal Bowel Diseases (IBD), structural and physical changes in the mucus layer remain poorly understood in the micro-inflammatory context of Irritable Bowel Syndrome (IBS).

  4. 23. Calcium transport in the Pacific oyster, Crassostrea gigas - in a changing environment

    Författare :Kirsikka Sillanpää; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate changes; Ussing chambers; Calcium uptake; Sodium potassium ATPase; Calcium ATPase; Sodium calcium exchanger; Calcium channel; Hemocytes; Mantle epithelium;

    Sammanfattning : Pacific oyster, Crassostrea gigas, is globally one of the most important farmed bivalve species. A prominent features of the C. gigas is the thick CaCO3 shell covering the body of the animal and protecting it from the environment. LÄS MER

  5. 24. On cell-penetrating peptides and cell-junction interactions

    Författare :Maria Lindgren; Nicholas Bodor; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neurokemi och neurotoxikologi; Neurochemistry and Neurotoxicology;

    Sammanfattning : Cell-penetrating peptides have the remarkable ability to carry hydrophilic macromolecules over the cellular membrane in an energy and protein independent manner. To synthesise and characterise new variants of cell-penetrating peptides, mainly aimed at finding analogues with minimised side effects and efficient cellular delivery, was one of the two main objectives of this thesis.

  7. 25. Studies on CAR and CLMP : two proteins of epithelial tight junctions

    Författare :Elisabeth Raschperger; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tight junctions are important structures for the function of epithelial cells. They are composed of multi-protein complexes that connect the plasma membranes of two adjacent epithelial cells to each other and function as paracellular barriers, which regulate flux of ions, solutes, proteins and cells across the epithelium.
