  1. 6. Novel actions of thrombin-derived host defense peptides

    Författare :Finja Hansen; Lund Dermatologi och venereologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Host defense peptides; Thrombin; Monocytes Macrophages; Gram-negative bacteria; LPS; TLR; Phagocytosis; Inflammation; Endocytosis;

    Sammanfattning : Thrombin-derived C-terminal peptides (TCPs) constitute a novel class of immunomodulatory host defense peptides, generated during infection and inflammation. Previous investigations have shown that TCPs of 2-3 kDa inhibit pro-inflammatory immune responses in vitro and in vivo, but their mode of action remained unclear. LÄS MER

  3. 7. Signaling and Adhesive Mechanisms in Acute Pancreatitis

    Författare :Darbaz Awla; Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; trypsinogen activation; Acute pancreatitis; leukocyte recruitment and adhesion;

    Sammanfattning : Acute pancreatitis (AP) is an inflammatory disease with variable severity ranging from mild interstitial edematous to severe necrotizing disease. The overall mortality rate of AP is 8-9%. Specific treatment of AP is lacking which is partly related to an incomplete understanding of the basic pathophysiology behind the disease. LÄS MER

  4. 8. Effects of Francisella tularensis infection on macrophage intracellular signaling

    Författare :Maxim Telepnev; Agneta Richter-Dalfors; Umeå universitet; []
    Nyckelord :Clinical Bacteriology; klinisk bakteriologi;

    Sammanfattning : Microbes contain a number of structural components, also known as pathogen associated molecular patterns (PAMP), which can be recognized by the host defense system. The PAMP serve as ligands for Toll-like receptors (TLR) expressed on phagocytic cells. LÄS MER

  5. 9. Commensal microbes, immune reactivity and childhood inflammatory bowel disease

    Författare :Cecilia Barkman; Göteborgs universitet; []
    Nyckelord :Inflammatory bowel disease; IBD; Pediatric; Childhood; Microbiota; T cells; B cells; cytokine; IL-12; monocytes; phagocytosis; intracellular signaling pathway; Crohn s disease; ulcerative colitis; children; flora;

    Sammanfattning : Inflammatory bowel disease (IBD) is characterized by chronic and relapsing intestinal inflammation of unknown etiology, but immune activation by the commensal microbiota probably plays a major role. The two major categories of IBD are ulcerative colitis and Crohn’s disease. LÄS MER

  7. 10. Host control of intracellular bacterial infections

    Författare :Emma Eriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Listeria monocytogenes; CD44; flagellin; Chlamydia pneumoniae; TLR; NOD; IFNalpha beta; IFN-gamma;

    Sammanfattning : In this thesis various immune mechanisms regulating control of infections with the intracellular bacteria Listeria monocytogenes and Chlamydia pneumoniae have been studied. These bacteria infect macrophages in which they can successfully grow. However, macrophages are potent killers of intracellular bacteria. LÄS MER
