The OC43 human coronavirus envelope protein is critical for infectious virus production and propagation in neuronal cells and is a determinant of neurovirulence and CNS pathology 2017-12-26 .txt text/plain 10925 469 50 In this study, we demonstrate that the fully functional HCoV-OC43 E protein (harboring specific TMD and PBM) is critical in infectious virus production and dissemination in epithelial and neuronal cell cultures and in the murine CNS and that it is a determinant of neurovirulence, a first demonstration for this coronavirus species. However, in these primary cultures, low levels of infected cells were visualized by immunofluorescence (IFA) where we detect the viral S protein, suggesting that infection was possible even for the complemented rOC/E-Stop virus but that production of new infectious progeny and eventual propagation were severely inhibited compared to wild type virus (Fig. 2C ). Infection of human LA-N-5 cells and mixed primary cultures of mouse CNS cells showed a similar virus production kinetic Infectious viral titer differences observed between experiments, revealed, by sequencing (G), the appearance of reversions at the position in the E gene where a stop codon was introduced are indicated by bold and underline. ./cache/cord-278578-vq5fy8m5.txt ./txt/cord-278578-vq5fy8m5.txt
