In addition, differential effects were observed in terms of chemokine receptor and chemokine expression, with healthy CD209+ DC displaying increased expression/co-expression of CCR6, CCR7, CXCR3, CXCR4 and CXCR5 when cultured with RA SF, while an increase in the chemokines CCR3, CXCL10 and CXCL11 was observed when cultured with PsA SF. Here, CCR6 is linked to rheumatoid arthritis.
