The SARS coronavirus 2 (SARS-CoV-2) infects lung cells and is responsible for the COVID-19 pandemic. The viral spike protein mediates entry of the virus into host cells and harbors an unusual activation sequence. The Infection Biology Unit of the German Primate Center (DPZ) – Leibniz Institute for Primate Research has now shown that this sequence is cleaved by the cellular enzyme furin and that the cleavage is important for the infection of lung cells. These results define new starting points for therapy and vaccine research. In addition, they provide information on how coronaviruses from animals need to change in order to be able to spread in the human population (Molecular Cell).
