CD107a expression of (a). CD56⁺CD3^- NK cells and (b) CD56⁺CD3⁺ NKT-like cells from SLE and healthy controls under the influence of IL-15. Comparison was also made among normal controls (normal), SLE patients with inactive disease (inactive SLE), and SLE patients with active disease (active SLE). PBMC were stimulated with or without IL-15 (10 ng/mL) for 18 hrs. Data was expressed as percent expression . and (normal control, ; SLE with inactive disease, ; SLE with active disease, ).
