Stimulation for 4 h with 1 μg/ml LPS, and for 1 h with 300 μM BzATP produced a significantly higher IL-6 release in SLE patients vs. HC (SLE-NS vs. HC: 1159 ± 83.87 vs. 330.7 ± 43.46, p < 0.0001; SLE-S vs. HC = 719.7 ± 112.6 vs. 330.7 ± 43.46, p = 0.004) and in patients without serositis vs. patients with serositis (SLE-NS vs. SLE-S, p = 0.003) (Figure 4C). The gene discussed is IL6; the disease is systemic lupus erythematosus.
