  1. 1. Leishmania donovani Lipophosphoglycan : Modulation of Macrophage and Dendritic Cell Function

    Författare :Katarina Tejle; Birgitta Rasmusson; Karl-Eric Magnusson; Olle Stendahl; Marita Troye-Blomberg; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Lipophosphoglycan; Leishmania donovani; macrophage; actin; phagocytosis; PKC alpha; dendritic cell; Microbiology and immunology; Mikrobiologi och immunologi;

    Sammanfattning : Leishmania donovani is a blood-borne tropicial parasite, which infects humans through bites by Phlebotomus sandflies. The parasite survives and multiplies inside macrophages in inner organs, and causes the deadly disease visceral leishmaniasis (Kala-Azar). LÄS MER

  3. 2. Effects of hypoxia on macrophage function in atherosclerosis

    Författare :Ellen Knutsen Rydberg; Göteborgs universitet; []
    Nyckelord :atherosclerosis; hypoxia; macrophage; IL-8; oxidized LDL; oxysterols; 15-lipoxygenase-2;

    Sammanfattning : Atherosclerosis is a complex disease, which affects large and medium sized arteries and is characterized by an arterial wall thickening. A constant supply of oxygen is needed to maintain cell functions in the atherosclerotic plaque. The oxygen distribution to the cells in the arterial wall depends on diffusion. LÄS MER

  4. 3. Intracellular lipids and inflammatory activity in macrophage foam cells

    Författare :Jenny Persson; Kardiovaskulär forskning - immunitet och ateroskleros; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; lipid droplet; cytokine; inflammation; adipophilin; perilipin; atherosclerosis; Macrophage; foam cell;

    Sammanfattning : Cardiovascular disease (CVD) is characterized by lipid accumulation and inflammation in arteries. The disease starts early in life with migration of monocytes into the arterial wall where they engulf entrapped lipoproteins and become macrophage foam cell. LÄS MER

  5. 4. Macrophage antigen expression in breast and colorectal cancers : A consequence of macrophage - tumour cell fusion?

    Författare :Ivan Shabo; Joar Svanvik; Bengt Gustavsson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Carcinogenesis is a sophisticated biological process consisting of a series of progressive changes in somatic cells from premalignant to malignant phenotype. Despite the vast information available about cancer cells, the origin of cancer and cause of metastasis still remain enigmatic. LÄS MER

  7. 5. Macrophage-material surface interactions

    Författare :Christina Gretzer; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Apoptosis; biomaterials; cell-cell interactions; cell-material interactions; cytokines; differentiation; fibrinogen; hydrogen peroxide; LPS; monocytes; particles;

    Sammanfattning : Material surface-stimulated activation of the macrophage and the release of mediators has been suggested to be an important factor for inflammation and tissue regeneration around biomedical implants. Macrophage interactions with particles released from implants as well as macophage-bacteria interactions are also involved in implant loosening processes. LÄS MER
