The serum levels of CXCL9 and CXCL10 were higher in anti-Jo-1 antibody-positive DM-ILD patients than in those with idiopathic pulmonary fibrosis, which distinguished this disease entity from idiopathic pulmonary fibrosis and anti-signal recognition particle antibody-positive myositis (Richards et al., 2009). Here, CXCL10 is linked to pulmonary fibrosis.
