  1. 1. Approaches to analyses of cytotoxic cells. And studies of their role in H. pylori infection

    Författare :Josef Azem; Göteborgs universitet.; Gothenburg University.; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter pylori; mucosal immunology; stomach; duodenum; asymptomatic; duodenal ulcer; gastric adenocarcinoma; NK cells; T cells; B cells; dendritic cells; cytotoxic;

    Sammanfattning : Helicobacter pylori infection causes chronic gastritis that may progress to peptic ulcers or gastric adenocarcinoma and thereby cause major world-wide health problems. Previous studies have shown that CD4+ T cells and the production of the cytokine IFN- × are important components of the immune response to H. pylori in humans. LÄS MER

  2. 2. The role of B cells in rheumatoid arthritis

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Maria Rehnberg; Göteborgs universitet.; Gothenburg University.; [2012]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; B cells; Rheumatoid arthritis; B cell depletion therapy;

    Sammanfattning : It has been known for a long time that B cells play a role in rheumatoid arthritis (RA). By production of autoantibodies, presentation of auto-antigens and by producing cytokines B cells may contribute to the pathogenesis of RA. In recent years it has been shown that anti-B cell therapy is a powerful tool in the treatment of RA. LÄS MER

  3. 3. B cell fate following immunization : from memory B cells to plasma cells

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Microbiology, Tumor and Cell Biology

    Författare :Paola Martínez Murillo; Karolinska Institutet.; Karolinska Institutet.; [2017]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Most approved successful human vaccines induce neutralizing antibody titers maintained above a given threshold for long-term protection against potential pathogen exposure. The pathogens targeted by these vaccines are antigenically stable and the relevant epitopes are immunogenic. LÄS MER

  4. 4. Immune maturation in early childhood and the influence of herpesvirus infections

    Detta är en avhandling från Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University

    Författare :Ebba Sohlberg; Stockholms universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Immune differentiation; monocytes; NK cells; B cells; T cells; Epstein-Barr virus; EBV; cytomegalovirus; CMV; IFN-γ; immunologi; Immunology;

    Sammanfattning : The quality of immune responses develops from birth into adulthood and in the context of the host microbial environment. The aim of this work was to study immune maturation during childhood, and how this process can be affected by the common herpesviruses; Epstein-Barr virus (EBV) and cytomegalovirus (CMV). LÄS MER

  5. 5. Immune cells in pregnant uterine mucosa : functional properties, cellular composition and tissue organization

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Lucia Mincheva-Nilsson; Umeå universitet.; [1993]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; immunologically privileged site; TCR γδ cells; CD56 cells; large granular lymphocytes; immunosuppression; cytokine; interleukin; lymphoid cell cluster; intraepithelial lymphocytes; glandular epithelium; immuno electron microscopy; pregnancy; decidua; lactoferrin; lactoferrin receptor; colostrum;

    Sammanfattning : The pregnant uterus mucosa - decidua - is an "immunologically privileged" site. A semiallogeneic embryo is allowed to survive, develop, and grow while the same tissue implanted outside the uterus will be rejected. The decidua basalis, which participates in the placenta formation, is a tissue rich in lymphoid cells. LÄS MER
