  1. 16. Live Single Cell Imaging and Analysis Using Microfluidic Devices

    Författare :Mohammad Ali Khorshidi; Helene Andersson-Svahn; Håkan Jönsson; Carolina Wählby; Johan Elf; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Single cell analysis; time-lapse fluorescence imaging; automated image analysis; microwell; droplet microfluidics; NK cells; single cell tracking; migration behavior analysis; cell-cell interaction; optical microscopy; image analysis; image processing; microfluidics; immune cells; tracking; counting; morphology analysis;

    Sammanfattning : Today many cell biological techniques study large cell populations where an average estimate of individual cells’ behavior is observed. On the other hand, single cell analysis is required for studying functional heterogeneities between cells within populations. LÄS MER

  3. 17. Interleukin 15 throughout murine natural killer cell biology

    Författare :Thuy Thanh Luu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Natural killer (NK) cells are innate immune cells that mount responses against virally infected, transformed and allogeneic transplanted cells. Equipped with cytolytic molecules and death receptors, NK cells mediate cytotoxicity against cells expressing low levels of MHC class I (MHC-I) or high levels of stress-induced molecules. LÄS MER

  4. 18. The role of natural killer cells and inflammatory mediators in preeclamptic pregnancies

    Författare :Nora Bachmayer; Eva Sverremark-Ekström; Katarina Bremme; Lucia Mincheva-Nilsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; preeclampsia; NK cells; Immunology; Immunologi; immunologi; Immunology;

    Sammanfattning : The maternal immune system must be able to adjust during pregnancy and accept the foetus that expresses paternal antigens. These changes are found both in placenta and circulation, including a mild inflammatory response. NK cells are abundant during the early part of pregnancy in placenta and are thought to be important for placental development. LÄS MER

  5. 19. Diversity of CD1d-restricted natural killer T cells

    Författare :Markus Sköld; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serology; Immunology; autoreactive; Ly49 receptor; CD1d; NKT cell; transplantation; Immunologi; serologi;

    Sammanfattning : The present study deals with natural killer (NK) T cells restricted to the antigen presenting molecule CD1d. NKT cells have been suggested to play a role in many diverse immunological situations such as clearance of different pathogens, protection against certain tumors, regulation of autoimmune reactions and as a link between innate and adaptive immune responses.

  7. 20. 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.
