Finally, monocyte chemotactic protein-1 (MCP-1) gene expression was not modified in e-RA (1.03 ± 0.42 vs. 1 ± 0.26 healthy, p = ns), but it was significantly decreased with TOFA (0.24 ± 0.4 vs. 1 ± 0.26 healthy, p < 0.01) (Figure 4C). The gene discussed is CCL2; the disease is rheumatoid arthritis.
