We noticed that, within CD45 RA–CCR7+ central memory Tregs, the frequency of CCR4+ CCR6+ CXCR3– Th17-like Tregs decreased in patients with sarcoidosis compared to the control group (26.65% (21.98; 32.04) vs. 32.59% (25.73; 38.39) with p < 0.01). This evidence concerns the gene CCR6 and rheumatoid arthritis.
