SPICE analysis clearly indicated that the expression and co-expression of CCR6, CCR7, CXCR3, CXCR4 and CXCR5 on the surface of CD209/CD14+ DC from PsA and RA patients, was more complex (overlapping of arcs and corresponding increase in pie segments) than that observed in HC (Figure 1E and Supplementary Figure 2B for the Pie legend). This evidence concerns the gene CD209 and rheumatoid arthritis.
