Phenotypic changes of the effector cells before (black bars) and after (grey bars) in vitro TKD/IL-2 stimulation. The percentage (left panel) and mean fluorescence intensity (mfi, right panel) values of CD3+ T cells and CD3-/CD56+ and CD3-/CD94+ NK cells were determined before and after a 4 days in vitro TKD/IL-2 stimulation by flow cytometry. The hatched bars indicate T and NK cell values derived from the patients blood during the therapeutic break 2 (L6+2), 6 (L6+6), 8 (L6+8), and 12 (L6+12) weeks after re-infusion cycle L6. Only viable, propidium-iodide negative cells were gated and analyzed.
