The number of positive cells bound by ATP1A1 to the viral particle S1 protein gradually increased at 60 min of infection compared to that of 0 min of infection; at 120 min of infection, the number of positive cells bound to the cell surface gradually decreased as the viral particles entered the cells and was less than the number of positive cells at the time of initial infection (Figure 7B,C). This evidence concerns the gene ATP1A1 and infection.
