  1. 1. Human intestinal T lymphocytes : a comparative analysis of phenotype and function in normal and inflamed mucosa

    Författare :Silvia Melgar; Nadine Cerf-Bensussan; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human intestinal mucosa; intraepithelial lymphocyte; lamina propria lymphocyte; γδ T cell; regulatory T cell; cytotoxicity; cytokine; basal lymphoid aggregate; ulcerative colitis; Crohn s disease;

    Sammanfattning : The epithelial lining of the gut must allow immediate contact with beneficial components as nutrients and normal microflora. At the same time it runs the constant risk of attack from pathogenic microbes and noxious agents. LÄS MER

  3. 2. Ecological impact of antibiotic treatment on human normal microflora

    Författare :Mamun-Ur Rashid; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Ceftobiprole;

    Sammanfattning : The skin and the mucosal surfaces of humans are colonized with microorganisms which are often referred as the normal microflora. There is a biological balance between the human host and the normal microflora in health. The extensive use of antibiotics in both humans and animals has caused the development of many resistant bacteria. LÄS MER

  4. 3. Colonization, persistence and virulence factors in Escherichia coli strains in the human intestinal microflora

    Författare :Forough Nowrouzian; Göteborgs universitet; []
    Nyckelord :Escherichia coli; large intestine; infant; newborn; bacterial adhesins; hemolysins;

    Sammanfattning : Escherichia coli is a member of the normal intestinal microflora of man and many animals. In this thesis, various aspects of the E. coli colonization pattern were studied, especially the role of so called virulence factors for persistence of E. coli in the gut microflora. LÄS MER

  5. 4. Experimental studies on the role of the gastrointestinal microflora in postsurgical adhesion formation

    Författare :Claes Bothin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Adhesions; adhesion formation; germfree; microflora;

    Sammanfattning : Introduction: Adhesions occurring after any kind of surgery is a common phenomenon and cause a great deal of morbidity and mortality, incurring a considerable burden on health care systems. Adhesions are especially prominent after lower abdominal and gynecological procedures (60-90 % of patients after one operation) causing infertility, pain syndromes and bowel obstruction as well as complicating subsequent surgery.

  7. 5. Human intraepithelial lymphocytes : a comparative study of phenotype, morphology, and functional properties of intraepithelial lymphocytes in gut and oral mucosa

    Författare :Carina Lundqvist; Marie-Louise Hammarström; Sten Hammarström; Per Brandtzaeg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human intraepithelial lymphocytes; alimentary tract; intestinal epithelium; gut luminal antigens; gingiva; γδ T cells; immunoelectron microscopy; cytokine mRNA; RT-PCR; extrathymic T cell maturation; RAG-1; periodontitis; mucosal immune system; CD4-CD8- αβ T cells; CD8 γδ T cells;

    Sammanfattning : Human intraepithelial lymphocytes (IEL) constitute a unique cell population situated in the first line of defense of the alimentary tract. Here they are continuously exposed to a massive antigenic load of high complexity. However, different conditions prevail along the alimentary tract. LÄS MER
