    Sammanfattning : Crohn's disease, a chronic inflammation of the bowel, is a multi-factorial condition where uncontrolled immune responses to luminal bacteria occur in genetically predisposed individuals. The first observable clinical signs are small ulcers that form at a specialised form of epithelium, follicle-associated epithelium (FAB). LÄS MER

    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. 3. Regulation of gut IgA induction by helper T cells

    Detta är en avhandling från Göteborgs universitet

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mucosal immunology; secretory IgA; T regulatory cells; T follicular helper cells; Th17 cells; Peyer s patches; IgA class-switch recombination; germinal centers;

    Sammanfattning : The gut is the largest lymphoid organ in the body. Due to intense and constant exposure to the outside world, it also functions as the most important portal of entry for many pathogens. LÄS MER

  4. 4. Particle Transcytosis Across the Human Intestinal Epithelium Model Development and Target Identification for Improved Drug Delivery

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Elisabet Gullberg; Uppsala universitet.; [2005]

    Sammanfattning : The use of nano- and micro-particulate carriers as delivery systems for oral vaccines has been under investigation for several decades. Surprisingly little is known of their uptake in the human intestine, despite the fact that substantial improvement is required to achieve adequate immune responses in man after oral administration.

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

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Anders Carlsson; Linköpings universitet.; Linköpings universitet.; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    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
