Introduction
EMR2 is a member of the EGF-TM7 family closely related to CD97. Chondroitin sulphates have recently been identified as ligands for EMR2 and CD97. Chondroitin sulphates have been implicated in the pathogenesis of rheumatoid arthritis (RA). The objective of this study is to determine the expression of EMR2 and the distribution of EMR2 and CD97 ligands in RA synovial tissue.
