Recently, IP-10, TNF receptor 2 (TNFR2) and galectin-9 were found to strongly correlate with global disease activity (r = 0.60–0.75) in two studies by Enders et al. (93, 94) IP-10, together with MCP-1 and eotaxin, was also higher in 54 JDM patients a median of 17 years after disease onset than matched healthy controls (92). The gene discussed is CXCL10; the disease is juvenile dermatomyositis.
