The expression of IL-6 in SLE compared to controls. Forty-one SLE samples and 20 controls, positive for β-actin reaction, were detected by qRT-PCR. The peripheral blood IL-6 expression was higher than the control group. Interleukin 6 in PBMCs of SLE was upregulated compared to the control group. There is no significant difference of the IL-6 expression between PBMCs and peripheral blood in SLE. SLE PB – peripheral blood with SLE; control PB – peripheral blood with control; SLE PBMCs – PBMCs with SLE; control PBMCs – PBMCs with control; *p = 0.05
