Infection with TB40/E had a stronger effect on Src activation (∼3 fold increase over mock); than that observed following infection with Towne/E p.40 (Figure 1B), which correlated with a higher amount of pUL130 in the TB40/E viral particle vs. that seen in the Towne/E p.40 viral particle (Figure 1A). This evidence concerns the gene SRC and infection.
