SARS-CoV-2, the coronavirus behind the COVID-19 pandemic, seems to provoke a muted antiviral reaction in human cells and in ferrets, according to a study posted to bioRxiv on March 24. The authors of the study, which is not yet peer-reviewed, propose that this distinctive transcriptional response may be responsible for the coronavirus’s high fatality rate.
“The value of really looking at how the host is responding to this virus is obviously very high and can inform [future work on] drugs,” says Carolina Lopez, who studies how viruses stimulate the immune system at University of Pennsylvania and who did not participate in the study.
