Scientific Abstract

2’-O-Methylation of mRNA by cellular methyltransferases (MTases) enables discrimination of self and non-self. We found that SARS-CoV-2 lacking the viral MTase Nsp16 triggers an enhanced innate immune response that depends on the RNA receptor MDA5. Thus, we will analyse Nsp16 as a means of SARS-CoV-2 to counteract innate immune sensing and will test the hypothesis that the 2’-O-methylation of viral RNA in general protects from sensing by the pattern recognition receptor MDA5.
