IL-17A and IL-12/23 p40 concentrations are elevated in body fluid from patients with AS. a Serum and (b) synovial fluid levels of TNFα, IL-17A, and IL-12/23 p40 in patients with ankylosing spondylitis (AS), patients with rheumatoid arthritis (RA), patients with osteoarthritis (OA), and healthy donors (HC). The Mann-Whitney U test was performed to determine statistical significance. Data are presented as means ± SDs. P values indicate significant differences between the two groups.
