Figure 4From: Interleukin-37 is increased in ankylosing spondylitis patients and associated with disease activity Elevated IL-37 mRNA and protein levels in AS patients with osteoporosis and complications. The expressions of IL-37 mRNAs in PBMCs (A) and IL-37 protein levels in serum (B) were measured in AS patients with OP (n = 24) and without OP (n = 22), as well as HC (n = 35). Results are expressed as mean ± SEM (A) Each individual is expressed as an symbol; horizontal lines indicate median values (B). OP, osteoporosis; HC, healthy control; NS, not significant; *P < 0.05; **P < 0.01.Back to article page
