AKT1 and infection: Consistent with a role for PI3K/AKT activation on late stages of the virus life cycle, viral titres were similar at early times post-infection but differed at later time points, with wt SFV titres exceeding SFV-YF by approximately one (MOI 0.1; Fig 3G) or more (MOI 10; Fig 3H) orders of magnitude by 12 hpi.
