CCL11 stimulation induced CCL11 and CCR3 mRNA. (A) RA FLS were stimulated with 200 ng/mL CCL11 for 12, 24 and 48 h. The expression of CCL11 mRNA at 48 h was induced by CCL11 self-stimulation (n = 5 patients). (B) The expression of CCR3 mRNA at 48 h was induced by CCL11 stimulation (n = 5 patients). (C) An antagonist of CCR3 (SB328437) at 100 µM reduced TNF-α-induced CCL11 secretion from RA FLS (n = 3 patients). NS no stimulation. The data are expressed as the mean ± SEM. *p < 0.05 was significant.
