Monocyte chemoattractant protein-1 (MCP-1) is a chemokine whose circulating levels have been detected in the lesions of several diseases such as pulmonary fibrosis, rheumatoid arthritis and atherosclerosis. However, the factors involved in the regulation of its production remain largely unknown. The main aim of the present paper was to ascertain the contribution of the familial/genetic factors on the production of MCP-1 in apparently healthy individuals. We also tested the possible relationships between the plasma levels of MCP-1 and other cytokines involved in bone metabolism (receptor activator NF-kB ligand (RANKL), osteoprotegerin (OPG), interleukin-6, macrophage-colony stimulating factor, tumor necrosis factor-α). Using ELISA assays the cytokine levels were measured in 570 apparently healthy individuals belonging to ethnically homogeneous Caucasian families. We found that MCP-1 levels were significantly (P < 0.01) correlated with RANKL (in both sexes) and with OPG only in women. The study showed that adjusted for potential covariates, 72% of the MCP-1 variance, was attributable to familial effects. About 49% was due to potential genetic factors and the rest was explained by common environmental sources shared by spouses within each family. In conclusion, our data provide reliable evidence for the substantial role of genetic factors in the determination of the phenotypic variability of MCP-1 plasma levels. The association between the osteoclastogenic cytokines and MCP-1 levels in healthy pedigrees is of special interest and might shed light on MCP-1 involvement in bone remodeling.
