The expression of seven IFN-inducible chemokine genes (RANTES, MCP-1, MIG, IP-10, CXCL11, IL-8 and CCL19) and five classic IFIGs (IFIT1, IFIT3, Mx1, OAS1 and Ly6e) in peripheral blood cells from 67 SLE patients, 20 RA patients and 23 healthy donors were measured using real-time reverse transcription PCR. This evidence concerns the gene CCL19 and systemic lupus erythematosus.
