FIG. 8. PKR knockout fully restores HCMV[TRS1-Mut 1] and HCMV[ΔI/ΔT] replication.
Triplicate wells of PKR KO A and PKR KO B cells, along with paired control cells, were infected with HCMV[TRS1-S2H], HCMV[TRS1-Mut 1], or HCMV[ΔI/ΔT] (MOI = 0.1). Virus accumulating in the medium from days 6 to 8 post-infection was titered on HF-TRS1 cells. Mean titers (and standard deviations) are shown.
