Glycoprotein of Nonpathogenic Rabies Viruses Is a Major Inducer of Apoptosis in Human Jurkat T Cells
This study sought to identify the RV protein that causes apoptosis. For this purpose, we first compared the ability of G and N proteins of a pathogenic and a nonpathogenic strain to trigger apoptosis of Jurkat rtTA by using an inducible Tet-on expression system. Then we analyzed apoptosis induced by a reverse genetic-engineered recombinant rabies virus in which the G gene from a nonpathogenic strain was replaced by its pathogenic strain counterpart. No other virus proteins than G of nonpathogenic RV strains induce apoptosis, and the G polypeptide of RV is a critical determinant for apoptosis in human cells.
