title: Serum levels of ifn-inducible PROTEIN-10 relating to the activity of systemic lupus erythematosus.
abstract: IFN-inducible protein-10 (IP-10) is supposed to act as a specific chemoattractant for Th(1)cells. Since Th(1)cells and IFN-gamma are shown to be important for developing systemic lupus erythematosus (SLE), we examined the relationship between serum IP-10 levels and the disease activity. Serum IP-10 levels were markedly increased in the SLE patients depending on the level of disease activity, whereas not in the patients with rheumatoid arthritis (RA). On the other hand, serum MCP-1 levels were increased to a similar extent both in RA and inactive SLE patients, and a little more elevated in active SLE patients. Serum IP-10 levels in SLE patients correlated positively and negatively with levels of anti-DNA antibody and complements, respectively, whereas MCP-1 levels correlated less or not at all. These results suggest that serum IP-10 levels could be a good indicator for the activity of SLE and that IP-10 could play an important immunological role in SLE.
