Similarly, IL-6 released following macrophage stimulation for 1 h with BzATP was significantly higher in SLE patients vs. HC (SLE-NS vs. HC: 328 ± 92.1 vs. 13.38 ± 0.76, p = 0.019; SLE-S vs. HC = 43.95 ± 9.49 vs. 13.38 ± 0.76, p = 0.005) and in patients without serositis vs. patients with serositis (SLE-NS vs. SLE-SS, p = 0.028) (Figure 4D). The gene discussed is IL6; the disease is synovial sarcoma.
