Viral non-structural protein (NSs) contribute to miR-146b expression resulted in inducing M2 macrophage differentiation. (A) Western blot analysis of SFTSV non-structural protein (NSs) and miR-146a/b expression (B) in THP-1 cells that were transfected control pCMV3 plasmid, NSs over-expression plasmid (pCMV3-NSs) for 48 h, respectively. SFTSV-infected THP-1 cells as a positive control. (B,C) THP-1 cells were transfected pCMV3 plasmid or pCMV3-NSs for 48 h. The expression of miR-146a/b and endogenous STAT1 detected by real-time PCR and western blot, respectively. (D) Immunofluorescence staining analyzed for CD86 and CD206 expression after transfected with pCMV3 or pCMV3-NSs for 48 h. Images were acquired using a confocal microscope. Right graph: fluorescence intensity of CD86 (green) and CD206 (red) in the regions delineated by a white line through ImageJ software.
