Emerging viruses, such as novel influenza A viruses (IAV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), pose a constant threat to animal and human health. Identification of host cell factors necessary for viral replication but dispensable for cellular survival might reveal novel, attractive targets for therapeutic intervention. Proteolytic activation of IAV hemagglutinin (HA) and SARS-CoV-2 spike protein (S) by the type II transmembrane serine protease (TTSPs), e.g. TMPRSS2 is sought to be critical for viral spread and pathogenesis. Here, we investigated the secondary structure of TMPRSS2 mRNA coding sequence and designed TMPRSS2-specific antisense oligonucleotides (ASOs). Several of these ASOs markedly reduced the TMPRSS2 expression and decreased IAV infection and SARS-CoV-2 entry into cells.
