Résumé
Influenza infections remain a burden on health care systems despite vaccination programs and marketed antiviral drugs. Immunomodulation through activation of innate sensors could represent innovative approaches to fight the flu. This study evaluated the ability of flagellin, agonist of Toll-like receptor 5 (TLR5), to control the replication of influenza A virus (IAV) in mice. First, we showed that systemic or intranasal administration of flagellin activated transcription of anti-viral genes in lung tissue. Prophylactic and therapeutic flagellin administration resulted in decreased levels of viral RNA and infectious virus in the lungs of H3N2 IAV-infected mice. The effect of the flagellin on viral replication was also observed in Ifnar
