  1. 11. Human cytotoxic lymphocyte differentiation in health and disease

    Författare :Heinrich Schlums; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cytotoxic lymphocytes, comprising natural killer (NK) cells and CD8+ cytotoxic T cells, eradicate infected or malignant cells by release of lytic granules and alarm the immune system through production of pro-inflammatory cytokines and chemokines. NK cells and CD8+ T cells belong to different arms of the immune system, employing complementary strategies for target cell recognition. LÄS MER

  3. 12. NK cell and dendritic cell interactions in innate immune responses

    Författare :Catrine M Persson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NK cells; Dendritic cells; crosstalk; recruitment; activation; CD94 NKG2AQa1; Toxoplasma gondii;

    Sammanfattning : Natural killer (NK) cells are cytotoxic cells of the innate immune system. They have been found to be critical in the defense against infections and also against some tumors. Recent studies have shown that NK cells require signals from accessory cells to induce their recruitment and activation at the site of infection or tumor growth. LÄS MER

  4. 13. Regulation of T cell effector functions in the intestinal mucosa

    Författare :Petra Holmkvist; Slemhinnans immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; T cells; memory; intestine; cytokines; differentiation; IL-18; inflammation; antigen presentation;

    Sammanfattning : T lymphocytes are a critical cellular component of the adaptive immune response. They are generated in the thymus from bone marrow derived progenitors, where they undergo commitment to the T cell lineage and differentiate and mature into naïve CD4+ and CD8+ T cells. LÄS MER
