Fig. 1. Real-time polymerase chain reaction analysis of CCL2, CCL4, CCR5, c-Fos, and c-Jun mRNA levels on peripheral blood leukocytes. The relative mRNA expression levels were normalized to the levels of GAPDH. The significance of differences was determined using Student's t-test. *p<0.05, n=10 (open bars healthy controls, coarse stippling bars rheumatoid arthritis patients). mRNA, messenger RNA.
