AMPK activating drugs 2DG, and A769662 significantly inhibited infection when added at post entry stages (Figure 4E); however, since one of the AMPK activating drugs, A769662, had a significantly greater impact on RVFV when added prior to or with infection, we cannot rule out that AMPK also inhibits RVFV entry. This evidence concerns the gene PRKAA2 and infection.
