ABSTRACT
OBJECTIVES:
CC motif chemokines are considered to be implicated in the pathogenesis of rheumatoid arthritis (RA) via recruitment of monocytes and lymphocytes. CC motif chemokine ligand 13 (CCL13)/monocyte chemoattractant protein-4 (MCP-4) is postulated to be a potent RA inducer. We conducted a study to more precisely clarify the role of CCL13 in RA pathogenesis.METHODS:
CCL13 expression was evaluated by enzyme-linked immunosorbent assay (ELISA) and immunohistochemical staining in serum samples and synovial tissues from RA patients. The effects of CCL13 against apoptosis were monitored on cultured synovial fibroblasts. The chemoattractant activity of CCL13 was evaluated by the Boyden chamber assay in monocytes (THP-1 cells) and human umbilical vein endothelial cells (HUVECs).RESULTS:
We found that CCL13 serum level and synovial tissue expression were increased in RA patients. CCL13 had chemoattractant activity for both THP-1 cells and HUVECs. Interestingly, CCL13 expression was positively regulated by tumor necrosis factor-alpha (TNF-α). Furthermore, apoptosis induced by hydrogen peroxide (H2O2) and serum deprivation was inhibited by CCL13 on the cultured synovial fibroblasts.CONCLUSIONS:
CCL13 may be associated with disease progression as a result of its antiapoptotic effects, increased macrophage infiltration, and synovial tissue angiogenesis in RA patients.
