CXCL12 and sarcoidosis: In regressing sarcoidosis, we detected correlations among the following miRNA-mRNA pairs: miR-146a-CCL19 (P < 0.001), let-7c-CCL19 (P = 0.007), miR-202-CXCL10 (P = 0.010), miR-212-CXCL10 (P = 0.002), miR-92a-CXCL12 (P = 0.008), miR-148a-CXCR4 (P = 0.002), miR-24-IL2RB (P = 0.006), and miR-25-IL2RB (P = 0.006) (Figure 4(c)).
