Coronaviruses use their spike proteins to select and enter target cells and insights into nCoV-2019 spike (S)-driven entry might facilitate assessment of pandemic potential and reveal therapeutic targets. Another key event for virus entrance into the host is represented by the cellular transmembrane protease serine 2 (TMPRSS2) that drives the spoke protein priming (Hoffmann et al., 2020). Viruses enter cells and initiate infection by binding to their cognate cell surface receptors. 2020 Apr 28. pii: S1097-2765(20)30264-1. doi: 10.1016/j.molcel.2020.04.022.
