MRC1 and autoimmune polyendocrinopathy: As shown in Figures 2A, C–E, in the high-expression MR (CD206) group, compared with the group without APS, the proportion of M-MDSC (13.24% vs 17.16% vs 21.30%, p< 0.01) (Figure 2C), PMN-MDSC (32.50% vs 40.26% vs 42.24%, p< 0.05) (Figure 2D), and total MDSC (45.74% vs 57.42% vs 63.54%, p< 0.01) (Figure 2E) differentiated from BMC gradually increased with increasing APS concentrations (from 80 μg/ml to 160 μg/ml).
