NS1-BP–NXF1 Export of Influenza M mRNAs
2026-08-25
The reference study identifies NS1-BP as a host factor that competes with influenza NS1 for NXF1 and helps route alternatively spliced M1 and M2 mRNAs to the cytoplasm. Its biochemical and cell-biological evidence supports a stage-specific export model in which NS1-BP, NXF1, and TREX-2-associated factors remain together until nuclear pore docking, clarifying how influenza virus overcomes NS1-mediated host mRNA export inhibition.

Selective Autophagy Balances IRF3 Antiviral Signaling
2026-08-24
Wu and colleagues show that CALCOCO2/NDP52-mediated selective autophagy limits IRF3 stability in a virus load-dependent manner, while PSMD14 preserves basal IRF3 through deubiquitination. The study provides a mechanistic explanation for how cells sustain type I interferon production without allowing prolonged IRF3 activity to intensify immune damage or suppression.
