  1. 1. Mechanisms involved in macrophage phagocytosis of apoptotic cells

    Författare :Anna Nilsson; Per-Arne Oldenborg; Karl-Eric Magnusson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; macrophages; dendritic cells; phagocytosis; apoptotic cells; senescent erythrocytes; CD47; SIRPalpha; LRP1; calreticulin; Immunology; Immunologi; immunologi; Immunology;

    Sammanfattning : Efficient removal of apoptotic cells is critical for development, tissue remodelling, maintenance of homeostasis, and response to injury. Phagocytosis of apoptotic cells is mediated by many phagocytic receptors, soluble bridging molecules, and pro-phagocytic ligands on the surface of apoptotic cells. LÄS MER

  2. 2. The CD40 Receptor - Target,Tool and Technology

    Författare :Peter Ellmark; Institutionen för immunteknologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; serology; transplantation; Immunologi; serologi; SPIRE; mammalian; library; cDNA; selection; receptor revision; phage display; scFv; human; CD40; antibodies;

    Sammanfattning : CD40 is a cell surface receptor of pivotal importance that is expressed on several of the cells in the immune system. It is critical for many important events, such as T cell dependent B cell activation, isotype switching, somatic mutation and generation of B cell memory. LÄS MER

  3. 3. B cell activation in vitro: thymus-dependent immune responses and bacterial cell surface proteins

    Författare :Karol Axcrona; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nuclear transport; bacterial Ig-binding proteins; CD40L promoter; CD21; Ig; B lymphocyte activation in vitro; CD40; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : In this thesis aspects of peripheral B lymphocyte differentiation were studied. Through in vitro experiments, B lymphocyte activation was assessed. B lymphocytes express immunoglobulin (Ig) specific for a certain antigen on the cell surface, and when surface Ig is crosslinked by an antigen, the cell is activated. LÄS MER

  4. 4. Innate and adaptive immune responses in the lungs. Contribution to protection against mycobacterial infections

    Författare :Olga Daniela Chuquimia Flores; Carmen Fernández; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Host defense against Mycobacterium tuberculosis (Mtb) is mediated by a combination of innate and adaptive immunity. In this thesis we investigated the role of components of innate system such as TLR2 signalling and alveolar epithelial cells type II (AEC II) in the immune responses against mycobacterial infections.

  5. 5. Regulation of lymphocyte activation and death

    Författare :Hanna Lindgren; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; N-substituted benzamides; apoptosis; NF-kB; NFAT; T cells; CD40L; serology; transplantation; Immunologi; serologi;

    Sammanfattning : T lymohocytes (T cells) and B lymphocytes (B cells) are important effector cells of the adaptive immune system. In response to infections, B cells are activated and produce antibodies against specific antigens. LÄS MER
