IL-10 induced the expression of miR-146b during SFTSV-induced macrophage differentiation. (A, B)The expression of miR-146a (A) or b (B) of THP-1 cells pretreated or not pretreated for 5 μM of the JAK/STAT inhibitor AG-490 or 10 μg/mL anti-IL-10 receptor (-αIL-10R) mAb and then infected with SFTSV at an MOI of 1 by quantitative real-time PCR. (C,D) Real-time PCR analysis of IL-13 (C) and IL-4 (D) mRNA expression in THP-1 cells infected with SFTSV. (E,F) Expression levels of IL-10 (E) and IL-4 (F) were measured using ELISA in SFTSV infected patient sera. (G) Western blot of STAT3 protein expression in SFTSV-infected THP-1 cells at various time points. Data are shown as means with ±SEM of three independent experiments (*P < 0.05, **P < 0.01, ***P < 0.001).
