Human MX1 orchestrates the cytoplasmic sequestration of neo-synthesized influenza A virus vRNPs

J. McKellar, F. Garcia de Gracia, C. Aube, A. L. Chaves Valadao, M. Tauziet, M. Arnaud-Arnould, A. Rebendenne, A. Neyret, E. Labaronne, E. P. Ricci, B. Delaval, R. Gaudin, N. Naffakh, S. Gallois-Montbrun, O. Moncorge, C. Goujon

This study shows human MX1 restricts influenza A virus by sequestering vRNPs in cytoplasmic clusters via dynein and microtubules, reducing viral production.

The N-terminal domain of MX1 proteins is essential for their antiviral activity against different families of RNA viruses

J. McKellar, M. Arnaud-Arnould, L. Chaloin, M. Tauziet, C. Arpin-Andre, O. Pourcelot, M. Blaise, O. Moncorge, C. Goujon

This study identifies the N-terminal domain of HsMX1 as essential for antiviral activity against IAV and VSV, with a conserved leucine crucial for function.

The DEAD box RNA helicase DDX42 is an intrinsic inhibitor of positive-strand RNA viruses

B. Bonaventure, A. Rebendenne, F. Garcia de Gracia, J. McKellar, S. Gracias, E. Labaronne, M. Tauziet, A. L. Chaves Valadao, E. Bernard, L. Briant, N. Gros, W. Djilli, M. Arnaud-Arnould, V. Courgnaud, H. Parrinello, , C. Goujon

This study identifies DDX42 as an intrinsic antiviral inhibitor that restricts HIV-1 and other positive-strand RNA viruses but not negative-strand RNA viruses.

SARS-CoV-2 replication triggers an MDA-5-dependent interferon production which is unable to efficiently control replication

A. Rebendenne, A. L. Chaves Valadao, M. Tauziet, G. Maarifi, B. Bonaventure, R. Planes, J. McKellar, S. Nisole, M. Arnaud-Arnould, O. Moncorge, C. Goujon

This study shows that SARS-CoV-2 triggers MDA-5-dependent interferon production in human cells, but this response fails to control viral replication.
