Figure 4From: Serum level of soluble CX3CL1/fractalkine is elevated in patients with polymyositis and dermatomyositis, which is correlated with disease activitySerum level of CX3CL1 in patients with polymyositis, patients with dermatomyositis and healthy controls. Serum samples were collected from polymyositis (PM) patients (n = 7), dermatomyositis (DM) patients (n = 22) and healthy controls (n = 20). (A) Concentration of serum soluble CX3CL1 measured by ELISA. Values are mean ± standard error of the mean. (B) CX3CL1 levels before and after treatment in PM and DM patients (n = 14; three PM patients and 11 DM patients). Symbols joined by a solid line represent data from an individual subject.Back to article page
