However, expression of human PLA2G6 by infecting cells with AAV-EF1a-PLA2G6 packaged in either the AAV-PHP.eB or AAV9 serotype is very low, even when we used a very high multiplicity of infection (MOI of 1000) (stars in Figure 4B; lanes 3 and 4). This evidence concerns the gene PLA2G6 and infection.
