The results of FCM analysis of the cells collected during the post-infection period showed that no suppressive effects were noted with SB203580 or U0126, inhibitors of p38 MARK and MEK/ERK1/2 signaling, respectively, while almost no RuV infection was observed in the A549 cells after treatment with SP600125, an inhibitor of JNK signaling. This evidence concerns the gene MARK1 and infection.
