  1. 16. Virulence of Salmonella enterica serovar typhimurium and innate antibacterial host responses

    Författare :Eva Bjur; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Salmonella; LPS; macrophages; NOS; SPI-2; thioredoxin; TrxA; TRAPC;

    Sammanfattning : The bacterial species Salmonella enterica consists of a collection of closely related enteric bacteria giving rise to diverse diseases in a wide range of hosts. In the murine infection model Salmonella enterica serovar Typhimurium (S. Typhimurium) causes an invasive disease which in many aspects resembles human typhoid fever. LÄS MER

  3. 17. CD64 (FcγRI) Expression on Neutrophil Granulocytes : A Diagnostic Marker of Acute Bacterial Infections

    Författare :Gustav Fjaertoft; Tony Foucard; Per Venge; Stelllan Håkansson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; CD64; FcγRI; Neutrophil; Infection; Newborn; Neonate; Pediatrik; Paediatric medicine; Pediatrisk medicin;

    Sammanfattning : Background. Newborn infants, especially preterm infants, have an increased susceptibility to serious and overwhelming bacterial as well as fungal infections. Symptoms of septicaemia in especially the very preterm neonates are vague and unspecific. LÄS MER

  4. 18. 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

  5. 19. Treatment of malignant tumors with histamine. Clinical and experimental studies

    Författare :Magnus Rizell; Göteborgs universitet; []
    Nyckelord :histamine; histamine H2-receptors; microdialysis; pharmacokinetics; ; neoplasm; sarcoma; melanoma; immunotherapy;

    Sammanfattning : For metastatic melanoma there is no treatment to prolong life. Histamine has in experimental tumors shown tumor inhibiting effects. In vitro, histamine inhibit phagocyte-derived radical oxygen species to protect natural killer and cytotoxic T-lymphocytes. LÄS MER

  7. 20. Immunoregulation by mononuclear phagocytes. Mechanisms and clinical implications

    Författare :Ana Romero; Göteborgs universitet; []
    Nyckelord :;

    Sammanfattning : The cytotoxic effector lymphocytes of the immune system, the natural killer (NK) cells and the CD8+ T lymphocytes (CTL), have been ascribed a pivotal role in defense against malignancy. However, the function of these cells is frequently compromised, in particular at sites of malignant cell expansion. LÄS MER
