    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. Gastrointestinal Permeability and Motility in Inflammatory Bowel Disease

    Författare :Anas Kh. Al-Saffar; Per Hellström; Dominic-Luc Webb; Åsa Keita; Uppsala universitet; []
    Nyckelord :Gastrointestinal motility; intestinal permeability; Mucosal; Ghrelin; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Synchronized motility, permeability and secretory (hormones and enzymes) events are integral to normal physiology. Smooth muscle syncytium operates with enteric nervous system (ENS) and endocrine signalling to accommodate, mix and control passage of ingested materials. LÄS MER

    Sammanfattning : Irritable bowel syndrome (IBS) is a chronic visceral pain disorder with female predominance, characterized by recurrent abdominal pain and disturbed bowel habits in the absence of an identifiable organic cause. This prevalent and debilitating disease, which accounts for a substantial economic and individual burden, lacks exact diagnostic tools and effective treatment, since its pathophysiology remains uncertain.

  5. 4. 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

  7. 5. Neuro-immuno-regulation of inflammation in the colonic mucosa : Focus on mast cells and eosinophils in bowel disorders

    Författare :Maria Teresa Casado Bedmar; Åsa Keita; Johan D Söderholm; Marie Carlson; Melanie Gareau; Linköpings universitet; []

    Sammanfattning : Intestinal homeostasis is key to control uptake across the mucosa and protect from harmful substances. Disturbances in the bidirectional communication between the gut and the brain are implicated in irritable bowel syndrome (IBS) and inflammatory bowel diseases (IBD), being Crohn’s disease (CD) and ulcerative colitis (UC) the two most common IBD subtypes.
