Compared with the control group, the expression of ABCB1 (Fig. 11A), CD247 (Fig. 11B), and KIR2DL3 (Fig. 11D) was significantly downregulated, while MX2 (Fig. 11E) was significantly upregulated in SLE patients (all P < 0.05), which was consistent with the results of this bioinformatic analysis. Here, KIR2DL3 is linked to systemic lupus erythematosus.
