ZBP1 does not restrict the spread of VZV or VZV-RHIMmut in RIPK3-deficient, apoptosis-capable cells.

Empty vector or ZBP1 expressing ARPE-19s were inoculated with parental ARPE-19 cells infected with parent VZV (pOKA) or VZV-RHIMmut. z-VAD-fmk (25 μM) was added at the time of inoculation where indicated. After 72 h cells were fixed and immunostained for VZV IE63 (red) to assess virus spread. Images are representative from at least 2 independent replicates. Scale bars represent 400 μm.
