  3. 7. On the role of innate cell interactions in inflammation and leukemia

    Författare :Rebecca E Riise; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Innate immunity; neutrophils; NK cells; caspase-1; apoptosis; myeloid leukemia; ROS; immunotherapy;

    Sammanfattning : Inflammatory cells of the innate immune system launch rapid and powerful effector responses in the combat against infectious pathogens. However, these inflammatory mediators may cause excessive damage to the host and, therefore, require rigid control systems to maintain the delicate balance between prompt clearance of infections and the risk of developing immunopathology.

  4. 8. Quantitative approaches to studying NK cell functional heterogeneity

    Författare :Per Olofsson; Björn Önfelt; Adnane Achour; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : It is commonly stated that the cell is the smallest functional unit of life. By analogy, then, the immune cell is the smallest functional unit of the immune system. LÄS MER

  5. 9. 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

  7. 10. Phagocyte-induced apoptosis in natural killer cells and T cells. Role of reactive oxygen species and regulation by histamine

    Författare :Markus Hansson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Malignant tumors frequently contain an infiltrate of leukocytes, usually cells of the monocyte/macrophage lineage and lymphocytes with anti-tumor activity such as natural killer (NK) cells and T cells. Clinical and experimental data suggest that monocytes/macrophages in tumors inhibit functions of adjacent NK cells/T cells and thereby suppress lymphocyte-dependent anti-tumor immunity. LÄS MER
