CCL19 and systemic lupus erythematosus: Also, a calculation of chemokine score, based on a calculation of mRNA expression of seven genes for IFN inducible chemokines: RANTES, MCP-1, CCLl9 (MIP-3B), monokine induced by IFNɣ (MIG), IP-10, I-TAC and IL-8 in peripheral blood cells of SLE patients, does show a correlation with activity of the disease, cumulative organ damage score, anti-Sm antibody and anti-RNP antibody titers.
