Vero cells were treated with different concentrations of MAG (i) 24 h before infection with PEDV(−1 dpi), (ii) immediately after infection (0 dpi), and (iii) 24 hr after infection (1 dpi), to determine if the time at which cells were exposed to MAG relative to the initiation of virus infection affected the anti-PEDV function of MAG. The gene discussed is MAG; the disease is infection.
