  1. 1. Activation of human eosinophils by exogenous danger signals

    Författare :Lena Svensson; Göteborgs universitet; []
    Nyckelord :Human eosinophils; danger signals; WKYMVm; bacteria; allergen; chemotaxis; CR3; free oxygen radicals; degranulation; formyl peptide receptor;

    Sammanfattning : Eosinophilic granulocytes are leukocytes that reside in the gastrointestinal and respiratory tracts. Their function in health is unknown. LÄS MER

  3. 2. Phagocytic-receptor signaling in human neutrophils

    Författare :Ragnhild Löfgren; Matthias P. Wymann; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The neutrophil granulocyte is one of the most mobile cells in the body and through a number of functions represents the first line of defense against invading pathogens. Adhesion and chemotactic receptors on the cell surface work together through modulation of the cytoskeleton, thereby enabling cell movement. LÄS MER

  4. 3. Signal transduction in human phagocytic cells during phagocytosis, oxidative activation and apoptosis

    Författare :Maria Forsberg; Emmanuelle Caron; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Neutrophils and macrophages are professional phagocytic cells that play a crucial role in host defense against invading microorganisms. They bind to, internalize, and subsequently kill microbes with an arsenal of reactive oxygen metabolites and microbicidal agents. LÄS MER

  5. 4. Tungstate Scintillators Growth, Structures and Properties

    Författare :Magnus Åsberg Dahlborg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; scintillators; single crystals; ZnWO4; HgWO4; neutron powder diffraction; X-ray diffraction; CdWO4; flux growth; tungstates;

    Sammanfattning : Tungstate crystals are well-known scintillators, which can be used as detector material for high-energy radiation and are often chosen as references in measurements on new luminescent materials. For measurements of excitation and relaxation properties, single crystals are desirable. LÄS MER

  7. 5. Characterization of host and microbe interactions affecting adherence, clearance and systemic spread of S. pneumoniae

    Författare :Sofia Dahlberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Streptococcus pneumoniae (the pneumococcus) mainly gives rise to diseases of the respiratory tract, such as pneumonia, acute otitis media and sinusitis, but it also causes severe invasive diseases, such as meningitis and sepsis. The pneumococcus accounts for approximately two million deaths world-wide every year, the majority of which are children in developing countries. LÄS MER
