Figure 4. Serum concentration of IL-33.

Figure 4

(A) Serum levels of IL-33 were measured in healthy controls (n = 12), and patients with SS (n = 10) and IgG4-RD (n = 7). (B) Serum levels of IL-33 were measured in 6 patients with IgG4-RD who were treated by corticosteroid after final diagnosis. Significant differences between groups were determined by the Mann–Whitney U test (*p < 0.05).
