Sensitivity of C6 Glioma Cells Carrying the Human Poliovirus Receptor to Oncolytic Polioviruses

摘要

A humanized line of rat C6 glioma cells expressing human poliovirus receptor was obtained and tested for the sensitivity to oncolytic effects of vaccine strains of type 1, 2, and 3 polioviruses. Presentation of the poliovirus receptor on the surface of C6 glioma cells was shown to be a necessary condition for the interaction of cells with polioviruses, but insufficient for complete poliovirus oncolysis.
