  • Varicella-zoster virus infection facilitates VZV glycoprotein E trafficking to the membrane surface of melanoma cells. Journal of medical virology Mo, C., Lee, J., Sommer, M. H., Arvin, A. M. 2003; 70: S56-8

    Abstract:

    Varicella-zoster virus glycoprotein E (gE) is the most abundant VZV glycoprotein on the surface of virus-infected cells. VZV gE has targeting sequences for the trans-Golgi network (TGN) and is transported from the ER to the TGN in infected and gE-transfected cells. In this study, VZV gE expressing melanoma cell lines were generated. gE is expressed under the control of the reverse Tet repressor (Tet-On). gE induced by Tet-On is retained at the ER as well as in the cis Golgi by immunofluorescence confocal microscopy. To test whether other viral protein(s) may facilitate gE trafficking and surface localization, MSPgE-vOka virus that contains MSPgE in place of wt gE was made. MAb 3B3 anti-gE does not bind to MSPgE. This MAb was used to track the localization of gE in Met-gE cells post MSPgE-vOka infection. gE became detectable mostly at the TGN and on the cell surface after viral infection. These data indicate that viral proteins facilitate the trafficking and cell surface expression of gE.
