The chemokine is a new class of cytokine. Now, more than 30 members of chemokine superfamily and 15 members of chemokine receptors (CXCR1-4, CCR1-8, CX3CR, CCR) have been identified. They were shown to be involved in the inflammatory response. The chemokine is classified into four subgroups (CXC, CC, C and CX3C). The local production of IL-8, MCP-1 and RANTES in rheumatoid inflamed joints has been reported. The predominance of several chemokines in other collagen diseases, such as SLE, systemic sclerosis and myositis is also described. Therefore, the inhibition of chemokines or chemokine receptors might be novel targets for various human disease, including collagen diseases.

Beta-chemokines attract and activate T cells and monocytes and have a key role in chronic inflammation. Certain beta-chemokines, such as monocyte chemoattractant protein-1 (MCP-1), have been reported to be upregulated in the idiopathic inflammatory myopathies (IIM). We studied the distribution of beta-chemokine receptors in polymyositis (PM), sporadic inclusion-body myositis (sIBM), dermatomyositis (DM), and control samples. CCR1-5 were localized to blood vessels in all samples. In addition, increased endothelial expression of CCR2A was observed in IIM. Subsets of inflammatory cells, identified as macrophages and T cells, in all three types of IIM expressed CCR2A, CCR2B, CCR3, CCR4, and CCR5. In contrast to an earlier report, we found CCR2B to be the most prominent MCP-1 receptor on inflammatory cells in IIM, especially in PM and sIBM. Strong CCR4 expression was present on myonuclei of regenerating muscle fibers. The prominence of the CCR2 receptors further underlines the importance of the interaction with their ligand MCP-1 in the immunopathogenesis of IIM and puts CCR2B forward as a potential target for future therapeutic intervention.
