Phenotype marker expression in activated and non-activated NK cells. The expression of selected phenotype markers was assessed by flow cytometry from the CD56-positive lymphocytes. The black, purple and blue colors represent the three individual Prodigy processes (P_NK1-3) and the circle and star symbols stand for the non-activated and 12-h cytokine-activated NK cells. The bars represent means ± SD.
