  1. 1. Islet xenotransplantation : An immunological study in the pig-to-mouse model

    Author : Birgitta Benda; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; xenotransplantation; porcine; islet; in vivo; knock-out mouse; immunohistochemistry; CsA; MDL 201; 449A; Ig; FcR; IL-6; perforin; granzyme B; macrophage; eosinophilic granulocyte; T cell; TCR; IFN- g; TNF- a; IL-2; Onkologi; Oncology; Onkologi; Clinical Immunology; klinisk immunologi;

    Abstract : Successful clinical xenotransplantation, i.e., transplantation between species, would eliminate the shortage of donor organs. In order to study the acute cellular rejection reaction following discordant xenogeneic transplantation, an experimental pig-to- mouse islet xenotransplantation model was established. READ MORE

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

    Author : Josef Azem; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : Helicobacter pylori; mucosal immunology; stomach; duodenum; asymptomatic; duodenal ulcer; gastric adenocarcinoma; NK cells; T cells; B cells; dendritic cells; cytotoxic;

    Abstract : 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. READ MORE

  3. 3. Exploring lymphocyte subsets, autoantibodies and the effect of B cell targeted therapies in rheumatic diseases

    Author : Natalie Sippl; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Nowadays, around 100 different diseases sort under the umbrella of rheumatic diseases(1). They involve different mechanisms and symptoms engaging joints, tendons, ligaments, bones, muscles but also vital organs like the kidneys nervous system and circulation. READ MORE

  4. 4. Modulation of tumor sensitivity to effector mechanisms of cytotoxic lymphocytes

    Author : Kristian Hallermalm; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Tumor escape; cytotoxic lymphocytes; interferon-gamma; TNF-alpha; granzyme B; Perforin; Fas ligand;

    Abstract : Today, ample evidence demonstrates a clear role for the immune system in the battle against cancer. However, the relatively high rate of mutation and proliferation of tumor cells, in combination with the selective pressure exerted by the immune system, can potentially lead to the generation of genetically altered tumor cells, which are able to evade recognition by the immune system and continue to grow and form tumors.

  5. 5. Molecular monitoring of acute graft-versus-host disease after allogenic stem cell transplantation

    Author : Marie Jaksch; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Stem Cell Transplantation; Acute Graft-versus-host disease; FasL; Granzym B; Chemokine receptors; chimerism;

    Abstract : Acute graft-versus-host disease (GVHD) remains a major barrier to the wider application of allogeneic stem cell transplantation (SCT) for a variety of diseases. GVHD occurs when the transplanted donor Tlymphocytes react to host antigens on antigen-presenting cells and attack host tissues. READ MORE
