1. 11. Neuro-immune regulation of macromolecular permeability in the normal human colon and in ulcerative colitis

   Författare :Conny Wallon; Johan Dabrosin Söderholm; Peter Naredi; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colitis; ulcerative; colon; sigmoid; cytology; immunohistochemistry; Gastroenterology; Gastroenterologi;

   Sammanfattning : Background and aim: Persistent stress and life events affect the course of ulcerative colitis (UC) by largely unknown mechanisms. Regulation of epithelial permeability to antigens is crucial for the balance between inflammation and immuno-surveillance, and increased intestinal permeability has been shown in patients with ulcerative colitis.

3. 12. Interactions between dietary chicory, gut microbiota and immune responses

   Författare :Haoyu Liu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : This thesis provides a better understanding of interactions between diet, gut microbiota, and immune responses to a specific dietary fiber source, chicory (Cichorium intybus L). This was achieved by examining the impact of chicory fiber on animal performance, digestibility, gut development, commensal bacteria community structure in small and large intestine, and follow-up reactions with specific immune components, cytoprotective heat shock protein (HSP) 27 and 72, in vivo and in vitro.

4. 13. Gut derived chronic inflammation in HIV-1 and chronic kidney disease : the role of the microbial metabolite TMAO and immunomodulatory effects of Vitamin D

   Författare :Catharina Missailidis; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Persistent immune activation with premature ageing and increased risk of cardiovascular disease (CVD) are features shared by HIV-1 infected individuals and patients with chronic kidney disease (CKD). Underlying dysbiosis, a failing mucosal barrier function and microbial translocation (MT) are contributing factors in both conditions. LÄS MER

5. 14. Identification and characterization of WASP and FKBP-like protein

   Författare :Ing-Marie Viklund; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Ulcerative colitis (UC) is a chronic inflammation of the colon which together with the related Crohn s disease (CD) represent the major forms of Inflammatory Bowel Disease (IBD). IBD is believed to arise in a dysfunctional intestinal barrier which allows the normal gut flora to trigger an unwanted chronic immune response in genetically susceptible individuals. LÄS MER

7. 15. Barley malt products for improved intestinal health

   Sammanfattning : Barley is a good source of dietary fibre, particularly β-glucan and arabinoxylan, to increase formation of short-chain fatty acids (SCFAs). Butyric and propionic acid are involved in the preservation of colonic barrier function, thus decreasing the risk of inflammation. LÄS MER
