The local production of enzymes and cytokines, and the activation of osteoclasts cause cartilage degradation and bone erosion, finally leading to joint destruction and functional disability. Fibroblast-like synoviocytes are unique cells of mesenchymal origin that constitute the intimal lining, which comprises 23 cell layers in normal conditions but can increase up to 15 layers in RA. Due to the border position between synovial tissue and synovial fluid, FLS obtain signals from both compartments and affect synovial tissue homeostasis in many ways. Moreover, it is increasingly appreciated that FLS contribute to the pathogenesis of RA by regulating inflammatory processes and, more directly, by eroding cartilage. A cell surface marker that defines FLS is CD55. The presence of CD55 in the intimal lining was initially reported by Medof et al.. Later work by Stevens et al. and Edwards and Wilkinson identified CD55 as a marker with an apparent specificity “1678014 for intimal fibroblasts in synovial disease. CD55, also known as decay-accelerating factor, is a broadly expressed cell surface molecule that protects cells from self-inflicted damage mediated by complement activation. CD55 controls complement by accelerating the decay of C3/C5 convertases. In line with this well-established function, CD55-deficient mice develop increased complement-mediated autoimmunity in a variety of antibody-driven models. Next to its role as a complement regulator, CD55 is a binding partner of CD97, an adhesion-type G protein-coupled receptor abundantly expressed on almost all leukocytes. AdhesionGPCRs are nonclassical heptahelical receptors that facilitate cell and matrix interactions of various cell types. CD97-positive macrophages closely associate with CD55-expressing FLS in the synovial intima. Using CD97-specific multivalent fluorescent probes, we previously demonstrated the ability of CD97 to interact with CD55 on FLS in RA synovium. Based on the sitespecific expression of CD55 and CD97, and the finding that CD97 facilitates leukocyte adhesion in vitro, we postulated that the CD55 Expression on Synovial Fibroblasts interaction of CD97+ int
