Coronavirus researchers led by Professor Rolf Hilgenfeld of the University of Luebeck and PD Dr. Albrecht von Brunn of the Ludwig-Maximilian Universitaet (LMU) in Munich have discovered how SARS viruses enhance the production of viral proteins in infected cells, so that many new copies of the virus can be generated. Notably, coronaviruses other than SARS-CoV and SARS-CoV-2 do not use this mechanism, which may therefore provide a possible explanation for the much higher pathogenicity of the SARS viruses. The findings appear in the EMBO Journal.
