  1. 16. The activation and regulation of plasmacytoid dendritic cells in SLE : and possible therapeutic interventions

    Författare :Karin Hjorton; Lars Rönnblom; Maija-Leena Eloranta; Hans Carlsten; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SLE; pDCs; NK cells; interferon; autoantibodies; immune complex; hydroxychloroquine; IRAK4 inhibition;

    Sammanfattning : Systemic Lupus Erythematosus (SLE) is an autoimmune disease, characterized by the presence of anti-nuclear antibodies and the formation of nucleic acid containing immune complexes (ICs), which can cause organ damage by deposition in tissues. ICs strongly trigger the plasmacytoid dendritic cells (pDCs) to produce interferon (IFN)-α, which potently activates the immune system. LÄS MER

  2. 17. The role of natural killer cells and inflammatory mediators in preeclamptic pregnancies

    Författare :Nora Bachmayer; Eva Sverremark-Ekström; Katarina Bremme; Lucia Mincheva-Nilsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; preeclampsia; NK cells; Immunology; Immunologi; immunologi; Immunology;

    Sammanfattning : The maternal immune system must be able to adjust during pregnancy and accept the foetus that expresses paternal antigens. These changes are found both in placenta and circulation, including a mild inflammatory response. NK cells are abundant during the early part of pregnancy in placenta and are thought to be important for placental development. LÄS MER

  3. 18. Imaging-based methods for NK cell studies at the single-cell level

    Författare :Quentin Verron; Björn Önfelt; Niklas Sandström; Michael Dustin; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; NK cells; microscopy; single-cell; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : The immune system provides defense against infectious agents such as viruses, bacteria and parasites. Besides eliminating extracellular agents, the immune system also constantly monitors our own cells for signs of transformation, including tumor development and virus infection. LÄS MER

  4. 19. Immunoregulation in an experimental model of allergic asthma

    Författare :Magnus Korsgren; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allergic asthma; macrophage migration inhibitory factor; eosinophils; gd T cells; NK1.1 T cells; natural killer cells; immunoglobulins; B cells; innate immunity; allergic airway inflammation; immediate hypersensitivity; Physiology; Fysiologi; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : In allergic asthma the immune response to antigen is inappropriate, leading to an inflammatory process in the respiratory mucosa. To further elucidate immunological mechanisms involved in the development of such inflammation, control mice and mice deficient in selected cell types or proteins, were used in experimental models of allergic asthma and anaphylaxis.

  5. 20. The Role of Plasmacytoid Dendritic Cells and Natural Killer Cells in Systemic Lupus Erythematosus

    Författare :Niklas Hagberg; Lars Rönnblom; Maija-Leena Eloranta; George Tsokos; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Systemic lupus erythematosus; plasmacytoid dendritic cells; natural killer cells; type I interferon; immune complex; SLAM receptors; autoantibodies; CD94 NKG2A; CD94 NKG2C; Medicinsk vetenskap; Medical Science; Immunologi; Immunology;

    Sammanfattning : Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by autoantibody production, which can eventually lead to immune complex (IC)-mediated organ damage. Due to the stimulation of plasmacytoid dendritic cells (pDC) by nucleic acid-containing ICs (DNA- or RNA-IC), patients with SLE have an ongoing interferon (IFN)-α production. LÄS MER
