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

    Author : Silvia Melgar; Nadine Cerf-Bensussan; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Recognition requirements and regulatory events directing T cell responses

    Author : Martin Gullberg; Eva-Lotta Larsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; T cell growth factor production; Lyt-2-positive T suppressor cell; Lyt-2-positive cytotoxic T lymphocytes; activation requirements of T lymphocytes; blocking of T cell functions;

    Abstract : The present study has considered cellular and molecular requirements in T cell responses. The central role of T cell growth factors (TCGF) in T cell responses prompted us to study the regulatory events directing TCGF production in lectin stimulated cultures. READ MORE

  5. 3. Control of Epstein-Barr virus infection by cytotoxic T lymphocytes

    Author : Pedro-Otavio de Campos-Lima; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Epstein-Barr virus; Cytotoxic T lymphocytes; T cell receptor; CTLescape mutants;

    Abstract : Cytotoxic T lymphocytes (CTL) play a critical role in response to Epstein-Barr virus (EBV), a widespread human herpes virus that persists in healthy carriers as a latent infection of B cells and is implicated in the pathogenesis of lymphoid and epithelial cell malignancies. Six virus encoded nuclear antigens, EBNA1-6, and three membrane proteins, LMP1, -2A and -2B, are regularly detected in EBV transformed lymphoblastoid cell lines (LCLs). READ MORE

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

    Author : Josef Azem; Göteborgs universitet; []
    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

  7. 5. Adoptive T Cell Therapy of Viral Infection and Cancer : Ex vivo Expansion of Cytomegalovirus- and Prostate Antigen-specific T Cells

    Author : Björn Carlsson; Magnus Essand; Thomas Tötterman; Malcolm Brenner; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; Immunotherapy; Adoptive T cell therapy; Dendritic cell; T cell; Tetramer; Cytomegalovirus; Transplantation; pp65; Prostate cancer; TARP; Prostate antigens; Immunologi; Immunology; Immunologi;

    Abstract : The main focus of my thesis has been to develop protocols for generating antigen-specific cytotoxic T lymphocytes (CTLs) and T helper cells (TH) for adoptive transfer to treat cytomegalovirus (CMV) disease and prostate cancer. CMV viremia is a severe complication in immunocompromised stem cell transplanted patients. READ MORE
