Krüppel-like factor 4 negatively regulates cellular antiviral immune response

Viral infection triggers activation of the transcription factors NF-κB and IRF3, which collaborate to induce the expression of type I interferons (IFNs) and elicit innate antiviral response. In this report, we identified Krüppel-like factor 4 (KLF4) as a negative regulator of virus-triggered signaling. Overexpression of KLF4 inhibited virus-induced… CONTINUE READING
