From: IL-1 family cytokines and soluble receptors in systemic lupus erythematosus
Levels of soluble cytokines and receptors of the IL-1 family in patients with inactive and active systemic lupus erythematosus (SLE). IL-18, IL-18 binding protein (IL-18BP), free IL-18, soluble IL-receptor 1 (sIL-1R1), sIL-1R2 and sIL-1R4 were measured in serum from 40 patients with inactive SLE and 22 patients with active SLE. Data are expressed as pg/ml of in patients with inactive SLE compared to patients with active SLE, by means of the non-parametric Mann-Whitney test. Horizontal bars represent medians and IQR; p values are given in each panel
