Abstract

Thiele et al. show that importin-α3 is one of the major nuclear transporters of NF-κB in the mammalian lung. High-level TNF-α-inducing HPAIVs inhibit importin-α3 mRNA transcription by interfering with its promoter activity. Thus, HPAIVs may evade antiviral immunity in the respiratory tract by generating a bottleneck in importin-α3 availability.
