Vidofludimus anti‑PRRSV activity in PAMs. A Viability of PAMs treated with the indicated concentrations of Vi for 48 h. B Western blot of N-protein in cells infected with PRRSV and treated with the indicated concentrations of Vi. C Relative PRRSV ORF7 mRNA levels determined by qRT-PCR. GAPDH was used as reference control. D Virus titration by TCID50 calculation. Error bars represent the mean ± SD. *, P < 0.05; **, P < 0.01; ***, P < 0.001; ****, P < 0.0001; ns: not significant.
