We found that CXCR3-expressed sing Treg cell subsets—CCR4+ CCR6–CXCR3+ Th1-like and CCR4+ CCR6+ CXCR3+ Th17.1-like Tregs—were significantly increased in patients with sarcoidosis vs. in the control group (14.45% (10.00; 19.48) vs. 10.51% (7.50; 14.36) with p < 0.01 and 27.90% (21.54; 37.36) vs. 22.80% (18.32; 27.00) with p < 0.01, respectively). This evidence concerns the gene CCR6 and sarcoidosis.
