Antiviral protein MDA-5 senses viral replication and governs immune response to SARS-CoV-2. Scientists at Sanford Burnham Prebys Medical Discovery Institute have identified the sensor in human lungs that detects SARS-CoV-2 and signals that it’s time to mount an antiviral response. The study, published today in Cell Reports, provides insights into the molecular basis of severe disease and may enable new strategies for the treatment and prevention of COVID-19.
“Our research has shown that MDA-5 is the immune cop that’s tasked to keep an eye out for SARS-CoV-2 and call for back-up,” says Sumit Chanda, Ph.D., director of the Immunity and Pathogenesis Program at Sanford Burnham Prebys and senior author of the study...
