CD38 surface expression on CD56^BrightCD16^Dim/− and CD56^DimCD16⁺ NK cell subsets between groups post IL-2 stimulation. No significant difference in CD38 surface expression was found between groups or within either NK cell subset pre and post IL-2 stimulation (a, b). No significant changes in CD38 surface expression was observed post drug treatment between or within groups on either NK cell subset (c, d)
