Increased Interleukin-17F is Associated with Elevated Autoantibody Levels and More Clinically Relevant Than Interleukin-17A in Primary Sjögren’s Syndrome

Figure 4

Comparison of serum levels of IL-17A and IL-17F between pSS patients with longer disease duration (≥8 years) and shorter disease duration (<8 years). (a) Serum IL-17A levels were significantly elevated in pSS patients with a longer disease duration. (b) Serum IL-17F levels were not significantly elevated in pSS patients with a longer disease duration.
