  1. 16. Host cell responses to Helicobacter pylori secreted factors

    Författare :Raquel Garcia Lobato Tavares; Sushil Kumar Pathak; Åsa Sjöling; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter pylori; Secreted proteins; Host cell responses; Macrophages; Apoptosis; Pro-inflammatory cytokines; MAPKs; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : The infection of the human gastric mucosa by the bacterium Helicobacter pylori can lead to the development of gastritis, gastroduodenal ulcers, and cancer. The factors that determine disease development in a small percentage of infected individuals are still not fully understood. LÄS MER

  3. 17. Macrophage expression of VEGF and VEGFR-1. Potential involvement in atherogenesis

    Författare :Linda Salomonsson; Göteborgs universitet; []
    Nyckelord :atherosclerosis; macrophages; oxLDL; statins; VEGF; VEGFR-1;

    Sammanfattning : The vascular endothelial growth factor (VEGF) family is a group of proteins which contributes to both neovascularisation and inflammation. Elevated levels of VEGF have been found in subjects with atherosclerosis and correlate to several cardiovascular risk factors, e.g. hypertension and hyperlipidemia. LÄS MER

  4. 18. TNFalpha expression in monocytes/macrophages

    Författare :Karolina Andersson; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicinska vetenskaper allmänt ; General biomedical sciences; Protein kinase; Macrophage; TNF;

    Sammanfattning : The recognition of microbes or microbial products by leukocytes is a key event in innate immunity. Binding of microbial products to cell surface receptors on phagocytes induce a response that includes the production of inflammatory mediators. One such mediator is the cytokine tumour necrosis factor alpha (TNF). LÄS MER

  5. 19. Exploring immune cell functions and ways to make use of them

    Författare :Evelina Vågesjö; Mia Phillipson; Michael Hickey; Uppsala universitet; []
    Nyckelord :leukocytes; neutrophils; macrophages; regulatory T cells; chemokines; VEGF-A; hypoxia; ischemia; muscle; Islets of Langerhans; diabetes; transplantation; wound healing;

    Sammanfattning : In addition to host defense, alternative functions of immune cells are emerging. Immune cells are crucial during healing of injured tissue, in formation of new blood vessels, angiogenesis, and also in maintaining the balance in inflammation having immune regulating functions.

  7. 20. 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
