Design outcomes

Primary

MeasureTime frame
Primary outcome is the nk-cell-cytotoxicity. Before, after and 12 h after the single bout of exercise blood will be drawn. From this blood samples nk-cells will be isolated and used in cytotoxicity assays with the cell line K562 as target cell.

Secondary

MeasureTime frame
Secondary edpoints are the characterization of NK-cells and the tumorinfiltration by NK-cells. For the characterization blood will be drawn (befor, after and 12 h after exercise) and the NK-cells will be investigated for their subgroups (CD56bright and CD56dim) and for the degranulation marker CD107a by flow cytometry. The tumor tissue will be removed and analysed for NK-cell infiltration by imunohistochemistry. Therefore the NK-cells will be stained by CD56 and CD57.
