The increased SAFA expression and cell viability under SFTSV infection.

(A) MEF cells were infected with SFTSV (MOI = 10) for 12, 24, or 48 h. Cell viability was analyzed using Cell Counting Kit-8 (CCK8). (B) MEF cells were infected with SFTSV (MOI = 0, 1, 5, 10) for 48 h. Cell viability was analyzed using CCK8. (C) MEF cells were infected with SFTSV (MOI = 0, 1, 5, 10) for 48 h. SAFA mRNA levels were analyzed by RT-PCR. (D) Vero cells were infected with SFTSV (MOI = 0, 1, 10) for 24 or 48 h. SAFA protein levels (green) were analyzed by immunofluorescence.
