  1. 21. Presentation of Salmonella antigens by dendritic cells

    Författare :Ulf Yrlid; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serology; Immunology; antigen processing and presentation; Dendritic cells; Salmonella; transplantation; Immunologi; serologi;

    Sammanfattning : This study investigates the interaction between dendritic cells (DC) and the Gram negative intracellular bacterium Salmonella typhimurium. Using in vitro and in vivo approaches, the capacity of DC to directly and indirectly present antigens from Salmonella-infected cells, cytokine production by infected DC, and activation of bacteria-specific T cells was analyzed.

  3. 22. Susceptibility gene mapping in multiple sclerosis

    Författare :Bing He; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Multiple sclerosis (MS) is a chronic inflammatory disease characterized by relapsing or progressive demyelination of the central nervous system (CNS). Increasing evidence supports that genetic factors confer susceptibility to MS resulting in an unknown mode of inheritance as a complex trait. LÄS MER

  4. 23. Transforming Growth Factor-b, Regulatory functions on normal lymphocytes and tumor outgrowth Regulatory functions on normal lymphocytes and tumor outgrowth

    Författare :Åsa Schiött; Institutionen för immunteknologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TGF-b; monocyte; rat; costimulation; Th2; ERK; tumor; TIL; Immunology; serology; Immunologi; transplantation; T-lymphocyte; serologi;

    Sammanfattning : Transforming growth factor-beta (TGF-b) is a well-characterised growth regulatory factor, which acts on most cell types. This thesis has focused on the regulatory roles of TGF-b on normal lymphocytes. One interesting finding is that TGF-b acts both costimulatory and inhibitory on T-lymphocytes. LÄS MER

  5. 24. The response of mast cells and serglycin-dependent proteases to parasitic infection : studies on mast cells during Toxoplasma gondii (murine) and Dictyocaulus vivparus (bovine) infection

    Författare :Osama Sawesi; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The proteoglycan (PG), serglycin (SG), is expressed in several hematopoietic cells and studies of the SG knockout mice (SG-/-) revealed prominent effects on the storage of certain mouse mast cell proteases (mMCPs) such as mMCP-4, -5 and -6.In this thesis, the role of SGPG during parasitic infection was addressed.

  7. 25. Liver transplantation in man. Gastrointestinal perfusion and inflammatory response

    Författare :Ebbe Rønholm; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; carbondioxide; complement activation; cytokines; endotoxaemia; hydrogen-ion concentration; liver transplantation; laser-Doppler flowmetry; PMN elastase; regional blood flow; reperfusion;

    Sammanfattning : Patients undergoing liver transplantation develop a systemic inflammatory response which eventually continues with development of a multiple organ dysfunction syndrome (MODS). Gastro-intestinal hypoxia or bacterial translocation has been proposed as the "motor" of MODS. LÄS MER
