WebFeb 20, 2024 · Coronavirus spike (S) glycoprotein trimers promote entry into cells and are the main target of the humoral immune response. We show here that SARS-CoV-2 S mediates entry in VeroE6 cells and in BHK cells transiently transfected with human ACE2, establishing ACE2 as a functional receptor for this novel coronavirus. WebThe viral spike glycoprotein attaches to a cell receptor, which can be transferrin receptor 1 for several New World arenaviruses and alpha-dystroglycan for lymphocytic choriomeningitis virus. Entry and endosomal uptake occur via either clathrin-dependent or clathrin-independent pathways, perhaps depending on the individual species of arenavirus.
