  1. 11. Ultrasound-assisted Interactions of Natural Killer Cells with Cancer Cells and Solid Tumors

    Författare :Athanasia Christakou; Martin Wiklund; Sabeth Verpoorte; KTH; []
    Nyckelord :Natural killer cell; cytotoxicity; heterogeneity; multiwell microchip; biocompatibility; ultrasonic cell manipulation; 3D cell culture; solid tumor; spheroid; high-resolution imaging; Biologisk fysik; Biological Physics;

    Sammanfattning : In this Thesis, we have developed a microtechnology-based method for culturing and visualizing high numbers of individual cells and cell-cell interactions over extended periods of time. The foundation of the device is a silicon-glass multiwell microplate (also referred as microchip) directly compatible with fluorescence microscopy. LÄS MER

  3. 12. Single cell studies of natural killer cell immune surveillance

    Författare :Elin Forslund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Our immune system protects us from microbes such as viruses, bacteria and parasitic worms. The immune system also plays a key role in fighting cancer and in carrying out a function termed ‘immune surveillance’, natural killer (NK) cells patrol tissues and participate in the elimination of transformed cells and established tumors.

  4. 13. T Cells and NK Cells in Coronary Artery Disease : Longitudinal and methodological studies in humans

    Författare :Karin Backteman; Jan Ernerudh; Lena Jonasson; Joachim Lundahl; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Coronary artery disease (CAD) is the leading cause of death worldwide and most often due to atherosclerosis. Atherosclerosis is a chronic inflammatory process that involves the arteries, inclouding those that supply blood to the heart muscle. LÄS MER

  5. 14. Oxidant-induced cell death in lymphocytes: mechanisms of induction and resistance

    Författare :Fredrik Bergh Thorén; Göteborgs universitet; []
    Nyckelord :reactive oxygen species; cell death; apoptosis; poly ADP-ribose polymerase-1; apoptosis-inducing factor; natural killer cells; phagocytes; dendritic cells;

    Sammanfattning : Reactive oxygen species (oxidants, oxygen radicals) produced by the phagocytic NADPH oxidase have pivotal roles in immunity. Patients lacking a functional NADPH oxidase suffer from chronic granulomatous disease, which is characterized by recurring bacterial infections and thus manifesting the importance of reactive oxygen species in host defense against bacteria.

  7. 15. Dynamics of natural killer cell homeostasis : implications for cell-based cancer immunotherapy

    Författare :Aline Pfefferle; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Natural killer (NK) cells comprise a central role within the innate immune system, eliminating virally infected, foreign and transformed cells through their natural cytotoxic capacity. Release of their cytotoxic granules is tightly controlled through the balance of a large repertoire of inhibitory and activating receptors, and it is the unique combination of these receptors on individual cells that confers them their immense diversity both in phenotype and functionality.
