  1. 1. Dendritic cell interactions with Gram negative bacteria

    Författare :Mattias Svensson; Immunologi; []

    Sammanfattning : The interaction between murine bone marrow-derived dendritic cells (DC) and the Gram negative bacteria Salmonella typhimurium and Escherichia coli have been characterised. These studies showed that DC phagocytosed and processed S. typhimurium and E. LÄS MER

  3. 2. Requirements for the Induction of Adaptive Immune Responses to Rotavirus

    Författare :Joy Nakawesi; Virusrekognition; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rotavirus; classical dendritic cells; Lymphoid organ hypertrophy; B cells; IgA; Retinoic acid; CD8 T cells; TLR3 and Poly I:C ;

    Sammanfattning : Rotavirus (RV) infections remain the leading cause of world-wide diarrhea-associated morbidity and mortality among children 200,000 deaths annually mostly in the low-income countries of Africa and Asia. Efficient clearance of the primary RV infection and protection from future re-infections is mediated by adaptive immune responses. LÄS MER

  4. 3. 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

  5. 4. Studies on 15-lipoxygenase in dendritic cells and leukotriene receptors in Hodgkin lymphoma

    Författare :Frida Schain; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Classical Hodgkin lymphoma (cHL) is histologically characterized by a minority of malignant cells, the so-called Hodgkin-Reed Sternberg (H-RS) cells, surrounded by inflammatory cells such as T lymphocytes, eosinophils, macrophages and mast cells. It is generally believed that various molecules released by the H-RS cells are of major importance in the pathophysiology of cHL. LÄS MER

  7. 5. Invariant NKT cells and CD1d in HIV-1 infection

    Författare :Sofia Andersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The invariant natural killer T (iNKT) cells are a subset of T lymphocytes that share characteristics of both innate and adaptive immunity. These cells are defined as T cells restricted by the lipid antigen presenting molecule CD1d and express an invariant T cell receptor (TCR) as well as classical natural killer (NK) cell markers.
