In addition, we observed a significant increase in CD209/CD14+ DC expression of the activation marker CD40 in PsA (p<0.01 ST vs PBMC), and RA (Figure 2A top; p<0.05 SFMC vs PBMC and p<0.01 ST vs PBMC) as well as CD80 in RA patients (Figure 2A bottom; p<0.001 ST vs PBMC and p<0.05 ST vs SFMC). This evidence concerns the gene CD14 and rheumatoid arthritis.
