  1. 16. Activation of neutrophils by mycobacteria and mycobacterial components

    Författare :Jenny Fäldt; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human neutrophils; mycobacteria; oxygen radicals; cytokines; mycobacterial glycolipids; priming;

    Sammanfattning : The genus Mycobacterium includes free-living saprophytes, opportunists, and human pathogens.Mycobacterium tuberculosis, the organism causing tuberculosis, as well as other pathogenicmycobacteria can survive and multiply inside phagocytic cells, but the underlying mechanisms areonly partly understood.

  3. 17. Regulation of human eosinophil transmigration across lung epithelium

    Författare :Lixin Liu; Uppsala universitet; []
    Nyckelord :Medical sciences; Eosinophils; regulation; migration; epithelial cells; lung; calcium; CD11b CD18; neutrophils; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Chemistry; klinisk kemi;

    Sammanfattning : Eosinophil infiltration into the lung tissues and airways is a hallmark of allergic asthma. To reach the lung lumen, eosinophils migrate across the vascular endothelium, through the interstitial matrix and across lung epithelium. LÄS MER

  4. 18. Chemotactic factors in the human follicle at ovulation

    Författare :Eva Runesson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chemokine; follicle; gonadotropin; human; ovary; ovulation;

    Sammanfattning : Ovulation is initiated by the midcycle gonadotropin surge, which leads to a controlled degradation of the follicle wall ending in follicular rupture and oocyte extrusion. The gonadotropins triggers several biochemical and biophysical changes such as vascular alterations, increased proteolytic enzyme activity and leukocyte extravasation, within the preovulatory follicle.

  5. 19. Interactions between Streptococcus pyogenes and the Human Immune System

    Författare :Maria Weineisen; Lunds universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serology; transplantation; Immunologi; serologi; virologi; mykologi; Immunology; mycology; Mikrobiologi; bakteriologi; virology; Biomedicinska vetenskaper; Neutrophils; Streptococcus pyogenes; Biomedical sciences; Phagocytosis; bacteriology; Microbiology; Integrins;

    Sammanfattning : Streptococcus pyogenes is a common human pathogen causing mild infections such as tonsillitis and pharyngitis, but is also the cause of life-threatening conditions. To be able to infect the human host, S. pyogenes express different virulence factors. The surface-expressed M protein is a major virulence factor of S. LÄS MER

  7. 20. Modulation of Receptor Signaling and Functional Selectivity in Neutrophils

    Författare :Michael Gabl; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neutrophils; G-protein coupled receptors; reactive oxygen species; ligands; functional selectivity; allosteric modulation;

    Sammanfattning : Neutrophils are important effector cells of the innate immune system and in the regulation of inflammation. Many of their functions, such as chemotactic migration, secretion of granule constituents and activation of the oxygen radical-producing NADPH-oxidase, are regulated by cell surface receptors. LÄS MER
