Serum 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.
