Influenza infected macrophages release viral ribonucleoproteins that shape the local host response

S. Fritzlar, S. Lakdawala, J. A. Roberts, L. J. M. Coin, Y.-M. Deng, J. Moselen, V. Le Sage, J. Mackenzie, L. Labzin, A. G. Brooks, P. Reading, S. Londrigan

This study shows that influenza-infected macrophages release viral ribonucleoproteins (vRNPs) that trigger inflammatory responses in uninfected cells through the RIG-I/MDA5 pathway.

Norovirus NS3 protein induces apoptosis through translation repression and dysregulation of BCL-2 pro-survival proteins

T. Aktepe, J. Deerain, S. Fritzlar, J. L. Hyde, J. Pearson, P. White, J. M. Mackenzie

This study identifies Norovirus NS3 protein as inducing apoptosis by repressing translation and dysregulating BCL-2 proteins, suggesting it as a potential antiviral target.

Macrophages only sense infectious SARS-CoV-2 when they express sufficient ACE2 to permit viral entry, where rapid cytokine responses then limit viral replication.

L. I. Labzin, K. Y. Chew, K. Eschke, X. Wang, T. Esposito, C. J. Stocks, J. Rae, R. Patrick, H. Mostafavi, B. Hill, T. Yordanov, C. L. Holley, S. Emming, S. Fritzlar, F. L. Mordant, , K. Schroder

The paper shows that ACE2-expressing macrophages allow SARS-CoV-2 entry and replication, triggering anti-viral responses, while ACE2-negative macrophages do not support viral entry or cytokine release.

Mouse Norovirus infection arrests host cell translation uncoupled from the stress granule-PKR-eIF2α axis

S. Fritzlar, T. Aktepe, Y.-W. Chao, M. McAllaster, C. Wilen, P. White, J. Mackenzie

This study shows that mouse norovirus infection suppresses host translation and cytokine production while promoting viral replication by recruiting G3BP1 to block stress granule formation.
