In addition, as baseline control, the amounts of cytokines in DMEM/F12 supplemented with 25% serum of highly ANA-IgG-positive SLE patients were IFN-γ (11.57 ± 3.24) pg/mL, IL-6 (0.86 ± 0.29) pg/mL, and IL-17 (32.41 ± 5.86) pg/mL. This evidence concerns the gene IL6 and systemic lupus erythematosus.
