The results indicated that the RA patients and HCs had similar absolute numbers of total ILCs (CD45+CD3-Lineage-CD161+CD127+) (Figure 1(b)), but the percentages of cNK cells (CD3-CD16+/CD56+) were significantly greater in RA patients with active disease status than in those with stable disease status and HCs (Figure 1(c)). This evidence concerns the gene IL7R and rheumatoid arthritis.
