Although the percentage of UN-SM B cells was decreased in patients with RA and pSS, we did not find the changed expression of ORAI1, ORAI2, and STIM2 in these B-cell fractions compared to that of HC (Figures 2H–J), indicating that B cells might be regulated by different signals in RA and pSS. This evidence concerns the gene ORAI2 and rheumatoid arthritis.
