Recent investigations on the pathway of cell entry by polyomavirus (Py) and simian virus 40 (SV40) have defined specific gangliosides as functional receptors mediating virus binding and transport from the plasma membrane to the endoplasmic reticulum (B. Tsai et al., EMBO J. 22:4346-4355, 2003; Gilbert and Benjamin, in press). These studies were carried out with C6 rat glioma cells, a heterologous host chosen for its known deficiency in ganglioside biosynthesis. Here, a cell genetic approach was undertaken to identify components required for the early steps of infection using mouse cells as the natural host for Py. Receptor-negative (R–) mouse cells, screened based on resistance to Py infection, were shown to bind Py but failed to allow entry of the virus. R– cells were also found to be resistant to SV40. Infectibility was restored or enhanced by the addition of the same specific gangliosides found in earlier studies with C6 cells. In one R– line, overexpression of caveolin-1 also increased infectibility. These results support and extend findings on gangliosides in lipid rafts as functional receptors and mediators of internalization for Py and SV40.
