  2. 21. Activation of murine cytotoxic cells with interelukin-2 and the bacterial superantigen staphylococcal entertoxin A

    Author : Hans Belfrage; Lund Kirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunologi; transplantation; serology; Immunology; cytokine; tolerance; LAK; NK; serologi; CTL; Staphylococcal enterotoxin A; SEA; Interleukin-2; murine; deletion; anergy;

    Abstract : Natural killer (NK) cells and T lymphocytes are the major effector cells that can recognize and kill tumor cells. NK cells have a constitutive cytotoxic activity and kill a wide spectrum of tumor cells while T cells recognize specific tumor antigens and need to be activated through their TCR to differentiate into cytotoxic T lymphocyte (CTL) killers or T helper cells.

  4. 22. Activation of human dendritic cells : role of the allergenic yeast Malassezia and NK cells

    Author : Eva Buentke; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Antigen-presenting cells; atopic eczema dermatitis syndrome; cytokines; dendritic cells; Malassezia; NK cells; yeast;

    Abstract : Immature bone marrow derived dendritic cells (DCs) patrol the periphery of our body, where they encounter and take up foreign antigens. Once activated, DCs migrate to regional lymph nodes to present peptides derived from these antigens to naive T cells, and elicit different T helper (Th) cell responses. READ MORE

  5. 23. The role of intestinal dendritic cells and the microbiota during oral Salmonella infection

    Author : Maria Fernández-Santoscoy; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Salmonella; dendritic cells; NK-kB; MyD88; CD40; CD103; IRF4; microbiota;

    Abstract : The intestinal pathogen Salmonella causes millions of infections per year worldwide. The immune response to these bacteria involves interactions between several cell types via specific molecules and is under the influence of the intestinal microbiota. Dendritic cells (DC) initiate immune responses including those to Salmonella. READ MORE

  6. 24. Immune maturation and lymphocyte characteristics in relation to early gut bacteria exposure

    Author : Sophia Björkander; Eva Sverremark Ekström; Hanne Frøkiær; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Allergy; cell-free supernatant; chemokines; colonization; cytokines; FOXP3; immune-maturation; lactobacilli; lymphocytes; NK-cells; Staphylococcus aureus; unconventional T-cells; molekylär biovetenskap; Molecular Bioscience;

    Abstract : At birth, the immune system is immature and the gut microbiota influences immune maturation. Staphylococcus aureus (S. aureus) and lactobacilli are part of the neonatal gut microbiota and have seemingly opposite effects on the immune system. S. READ MORE

  7. 25. On the role of Natural Killer cell immunogenetics for the outcome of immunotherapy in acute myeloid leukemia

    Author : Brwa Ali Hussein; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Natural killer cells; Acute Myeloid Leukemia; immunotherapy; HDC IL-2; NKG2A; NK education; SNPs; NK activating receptors; HLA class I;

    Abstract : Numerous studies have revealed that natural killer cells have fundamental roles as effector cells in myeloid leukemias. Thus, understanding NK cell-related biomarkers that influence clinical outcome are warranted. READ MORE
