CD27 and systemic lupus erythematosus: In Figure 4, French samples are presented together with data from the Chilean groups for each corresponding miRNA investigated: miR-494 as miRNA discriminating naive CD27− B cells of SLE patients versus HC (Figure 4a), miR26a as miRNA differentially expressed in memory CD27+ B cells of SLE patients versus HC (Figure 4b), and miR-21 and miR-145 as discriminating SLE from SLE-LN patients independently on B cell subsets, each one being representative of the three different profiles observed (Figure 4c).
