MYH9 and viral infectious disease: Next, we infected simMYH9-transfected cells with TCRV and LCMV at an MOI = 1 for 48 h, which were shown to infect primary mouse cells at high levels (16), and we found that reduced expression of Myh9 also resulted in a significant decrease in viral infection levels for both viruses (Fig. 1F), indicating that MYH9 proviral activity is conserved in both human and mouse cells.
