Higher concentrations of CXCL9 (MIG) and CXCL10 (IP-10), Th1 chemoattractants and ligands to the regulator of leukocyte trafficking CXCR3, were both significant in the same direction as several autoimmune diseases, with strongest signals for myasthenia gravis, and several JIA subtypes, as well as IBD, CEL, AS, and sarcoidosis. The gene discussed is CXCL9; the disease is juvenile idiopathic arthritis.
