  1. 1. Intestinal Mucosa Reconstitution and Protection: Impact of Luminal Factors

    Detta är en avhandling från Department of Surgery, Clinical Sciences Lund, Lund University

    Författare :Yilei Mao; Lunds universitet.; Lund University.; [1997]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Probiotics; Pectin; Oat; Methotrexate; Lactobacilli; Intestinal injury; Intestinal immunity; Intestinal barrier; Enterocolitis; Fiber; Radiation; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : The gastrointestinal mucosa is one of the most rapidly proliferating tissues in the body, and serves as a barrier to luminal bacteria and toxins. Enteral nutrition, luminal fiber and probiotics are of crucial importance for the integrity of this barrier. LÄS MER

  2. 2. Intestinal dendritic cell migration and induction of T cell responses

    Detta är en avhandling från Section for Immunology, Lund University

    Författare :Karin Hägerbrand; Lunds universitet.; Lund University.; [2015]

    Sammanfattning : The intestine represents the body’s largest surface exposed to the outer world and is thus a major entry site for pathogens such as bacteria and viruses. The intestinal immune system has the important task of protecting us against infection while maintaining tolerance against the vast amount of commensal microbes populating the intestinal tract and the multitude of foreign antigen present in the diet.

  3. 3. The ontogeny and function of intestinal dendritic cells

    Detta är en avhandling från Mucosal Immunology, EMV, Lund University

    Författare :Emma Persson; Lunds universitet.; Lund University.; [2014]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mesenteric lymph nodes; Intestine; Dendritic cells; Gut-homing; Th17 cells; Oral tolerance; Immunity;

    Sammanfattning : The intestinal mucosa presents a huge surface area to the external environment and the intestinal immune system is continually exposed to a wide array of foreign antigens derived from resident intestinal microbiota as well as dietary constituents, including food proteins. In order to maintain intestinal homeostasis, the intestinal immune system relies on the ability to generate tolerogenic responses to innocuous antigen while maintaining the ability to develop effective immune responses to intesinal pathogens.

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

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Silvia Melgar; Umeå universitet.; [2002]
    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

  5. 5. Natural killer T (NKT) lymphocytes regulate of intestinal tumor immunity

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Ying Wang; Göteborgs universitet.; Gothenburg University.; [2017]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NKT lymphocyte; intestinal tumor; CD1d; colrectal cancer; immunoregulation; α-gagactosylceramide;

    Sammanfattning : CD1d-restricted natural killer T (NKT) lymphocytes are known as potent early regulatory cells of immune responses, acting as a bridge between innate and adaptive immunity. While invariant NKT (iNKT) cells have a protective role in many tumor models, their ability to promote intestinal inflammation, known to enhance intestinal cancer, raised the question if they would be protective in intestinal tumor development.
