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

22. Activation of human dendritic cells : role of the allergenic yeast Malassezia and NK cells
Sammanfattning : 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. LÄS MER
23. The role of intestinal dendritic cells and the microbiota during oral Salmonella infection
Sammanfattning : 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. LÄS MER
24. Immune maturation and lymphocyte characteristics in relation to early gut bacteria exposure
Sammanfattning : 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. LÄS MER
25. On the role of Natural Killer cell immunogenetics for the outcome of immunotherapy in acute myeloid leukemia
Sammanfattning : 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. LÄS MER
