Positive correlations between disease severity and serum cytokine levels, including C-X-C motif chemokine ligand 10 (CXCL10), C-C motif chemokine ligand 2 (CCL2), Galectin-9, interleukin-18 (IL-18), tumor necrosis factor-α (TNF-α), and TNF receptor 1 (TNFR1) were observed within anti-TIF1-γ antibody-positive DM patients [11]. The gene discussed is CCL2; the disease is dermatomyositis.
