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 (%) ± SEM. ^∗ p < 0.05 and ^∗∗ p < 0.01 (normal control, n = 12; SLE with inactive disease, n = 14; SLE with active disease, n = 18).
