Abstract
- Chinese hamster ovary (CHO) cells are traditionally regarded as nonpermissive cells for herpes simplex virus type 1 (HSV-1) infection as they lack the specific entry receptors, and modified CHO cells have been instrumental in the identification of HSV-1 receptors in numerous studies. In this report we demonstrate that the HSV-1 strain 17+ variant HSV1716 is able to infect unmodified CHO cells but only if the virus is propagated in baby hamster kidney (BHK) cells. Infection of CHO cells by BHK-propagated HSV1716 results in expression of immediate-early, early, and late viral genes, and infectious progeny virions are produced. In normally cultured CHO cells, up to a maximum of 50% of cells were permissive for BHK-propagated HSV1716 infection, with 24 h of serum starvation increasing this to 100% of CHO cells, suggesting that the mechanism used by BHK-propagated virus to infect CHO cells was cell cycle dependent. The altered tropism of HSV1716 was also evident in another nonpermissive mouse melanoma cell line and is an exclusive property resulting from propagation of the virus using BHK cells, as viruses propagated on Vero, C8161 (a human melanoma cell line), or indeed, CHO cells were completely unable to infect either CHO or mouse melanoma cells.
