High values of Th1 (CXCL10) and Th2 (CCL2) chemokines in patients with psoriatic arthtritis.

Abstract

In conclusion, high circulating levels of CXCL10 and CCL2 have been found in PsA patients, with a Th1 immune predominance in the early phase of the disease. A decline of CXCL10 levels has been observed in long lasting PsA, with a significant increase of the CCL2/CXCL10 ratio, suggesting a shift from Th1 to Th2 immune response in long duration PsA.
