  1. 1. Endothelial activation and inflammation in the tumor microenvironment

    Författare :Hua Huang; Anna Dimberg; William C. Aird; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tumor angiogenesis; endothelial activation; leukocyte recruitment; VEGF-A; αB-crystallin; ELTD1;

    Sammanfattning : Tumors are composed not only of malignant cells, but also of various types of normal cells, including vascular cells and infiltrating immune cells, which drive tumor development and progression. The tumor vasculature is abnormal and dysfunctional due to sustained tumor angiogenesis driven by high levels of pro-angiogenic factors. LÄS MER

  3. 2. On the role of mast cells in chemokine-induced leukocyte recruitment

    Författare :Yusheng Wang; Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chemokines; mast cells; TNF-alpha; dexamethasone; P-selectin; E-selectin; activation; Medicine human and vertebrates ; endothelial cells; adhesion; Neutrophil; Medicin människa och djur ; recruitment;

    Sammanfattning : Leukocyte recruitment is considered to playa key role in numerous inflammatory diseases. Tissue accumulation of Jeukocytes is a multi-steps process comprising rolling, adhesion and transmigration. LÄS MER

  4. 3. Role of adhesion molecules and chemokines in TNF-alpha-induced leukocyte recruitment

    Författare :Xiao Wei Zhang; Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; intravital microscopy; microcirculation; inflammation; adhesion; leukocyte; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Migration of leukocytes from the circulating blood into the extravascular tissue is a key component in inflammatory reactions. Leukocyte extravasation (rolling-activation-adhesion-transmigration) is strictly coordinated by adhesion molecules and chemokines expressed on cell surfaces and in tissues. LÄS MER

  5. 4. On the Biosynthesis and Processing of Cathepsin G, Leukocyte Elastase, and Azurocidin ­ neutrophil granule members of a hematopoietic serine protease superfamily

    Författare :Anders Lindmark; Avdelningen för hematologi och transfusionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular fluids; Haematology; sorting; Activation; propeptide; Hematologi; extracellulära vätskor;

    Sammanfattning : The serine proteases cathepsin G, leukocyte elastase, proteinase 3, and the inactive protease homologue azurocidin, stored in the azurophil granules of neutrophils, belong to a hematopoietic serine protease superfamily with members in mature effector cells of bone marrow origin. Promonocytic U-937 cells were used for studying the biosynthesis of cathepsin G and leukocyte elastase by biosynthetic radiolabelling. LÄS MER

  7. 5. Trypsinogen and neutrophil activation in acute Pancreatitis

    Författare :Hannes Hartman Magnusson; Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute pancreatitis; trypsinogen activation; adhesion; neutrophil extracellular traps;

    Sammanfattning : Background and aims: Acute pancreatitis (AP) is a common condition characterized by premature protease activation, abdominal pain and leakage of pancreatic enzymes to the circulation. Approximately 10% develop systemic inflammation and persistent organ failure. LÄS MER
