Abstract

Because of its very low titer, varicella-zoster virus (VZV) infectivity is usually transferred by passage of trypsin dispersed infected cells. Previously, we observed that gC biosynthesis was markedly delayed in monolayers inoculated with cell free virus. In this report, we investigated the kinetics of gC expression in more detail and included studies of monolayers inoculated with trypsin dispersed infected cells, the more traditional method of VZV infection. Extensive imaging analyses disclosed that gC was detectable in some inoculum cells, but little gC biosynthesis occurred during the first 48 hpi in the newly infected underlying monolayer. In contrast, during the first 24-48 hpi, expression of VZV gE and gB was easily detectable. Using real-time RT-PCR, we found a delay in accumulation of VZV gC transcripts that paralleled the delay in expression of VZV gC protein. Treatment with hexamethylene bisacetamide (HMBA) increased expression of both gC protein and gC mRNA. HMBA treatment also increased virus titer by 4-fold, but paradoxically reduced plaque size in the titration assay. Finally, we examined skin vesicles from cases of chickenpox and zoster in humans and observed abundant amounts of gC expression. In short, this report documents an unexpected delay in both gC mRNA and protein production under all conditions of VZV infection of cultured cells.
