Cytotoxic Function and Cytokine Production of Natural Killer Cells and Natural Killer T-Like Cells in Systemic Lupus Erythematosis Regulation with Interleukin-15

Figure 2

The percentage of NK cells from peripheral blood of SLE patients and healthy normal controls under the influence of IL-15. (a) Total NK cells. (b) CD56^dim NK and CD56^bright NK cells. MNCs were stimulated with or without IL-15 (10 ng/mL) for 18 hrs. Cells were stained by anti-CD3 and anti-CD56 antibodies and quantified by flow cytometry. Data was expressed as percent expression . and (normal control, ; SLE with inactive disease, ; SLE with active disease, ).
