CXCL10 and its receptor CXCR3 regulate synovial fibroblast invasion in rheumatoid arthritis

Abstract

We describe and characterize a new autocrine/paracrine role of CXCL10/CXCR3 in the regulation of FLS invasion in rats with arthritis and in RA patients. These observations suggest that the CXCL10/CXCR3 axis is a potential new target for therapies aimed at reducing FLS invasion and its associated joint damage and pannus invasion and destruction in RA.
