  1. 6. The leukocyte complexity and mutational landscape of periampullary adenocarcinoma. Morphology matters

    Författare :Sebastian Lundgren; Tumörmikromiljö; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; periampullary adenocarcinoma; pancreatic cancer; immune microenviroment; prognosis; macrophages; natural killer cells; natural killer T cells; T cells; B cells;

    Sammanfattning : Background: Periampullary adenocarcinomas are a heterogenous group of tumours with poor prognosis that hasnot improved considerably the last decades. Tumour morphology, i.e. intestinal type (I-type) or pancreatobiliarytype (PB-type), has been demonstrated to be a more relevant prognostic factor than anatomical origin. LÄS MER

  3. 7. 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

  4. 8. Function of natural killer cells in Helicobacter pylori infection and gastric cancer

    Författare :Åsa Lindgren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Natural killer cells; Helicobacter pylori; gastric cancer; IFN-γ; TLR;

    Sammanfattning : Helicobacter pylori infection is one of the most wide-spread infections in the world and causes a chronic inflammation in the gastrointestinal mucosa characterised by increased production of IFN-γ and is associated with an increased risk of developing gastric cancer. The mechanisms behind the development of gastric cancer in H. LÄS MER

  5. 9. 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

  7. 10. Immunoregulation in an experimental model of allergic asthma

    Författare :Magnus Korsgren; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allergic asthma; macrophage migration inhibitory factor; eosinophils; gd T cells; NK1.1 T cells; natural killer cells; immunoglobulins; B cells; innate immunity; allergic airway inflammation; immediate hypersensitivity; Physiology; Fysiologi; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : In allergic asthma the immune response to antigen is inappropriate, leading to an inflammatory process in the respiratory mucosa. To further elucidate immunological mechanisms involved in the development of such inflammation, control mice and mice deficient in selected cell types or proteins, were used in experimental models of allergic asthma and anaphylaxis.
