claim: interferons and viruses induce a novel truncated ace2 isoform and form the full-length sars-cov-2 receptor
evidence_1: we then showed that dace2 , but not ace2 , is induced in various human cell types by ifns and viruses; this information is important to consider for future therapeutic strategies and understanding covid-19 susceptibility and outcomes.", "our discovery of dace2 , a truncated version of ace2 , demonstrates that it is dace2 and not ace2 that is induced by ifns and viruses, including sars-cov-2.")
