MICB and systemic lupus erythematosus: As was shown in Figure 2, MICB mRNA expression was significantly or marginally significantly upregulated in SLE B cells (489.80 ± 95.50 versus 352.66 ± 96.13; P = 1.31 × 10−2; 7 SLE patients versus 9 controls), monocytes (1661.14 ± 532.87 versus 1065.38 ± 220.72; P = 4.97 × 10−2; 5 SLE patients versus 5 controls), tubulointerstitial samples (4.33 ± 0.22 versus 4.21 ± 0.16; P = 7.45 × 10−2; 32 SLE patients versus 15 controls), and glomeruli samples (7.92 ± 0.52 versus 6.77 ± 0.23; P = 2.18 × 10−13; 32 SLE patients versus 14 controls).
