IKK? modulates RSV-induced NF-?B-dependent gene transcription.


ABSTRACT: Respiratory syncytial virus (RSV), a negative-strand RNA virus, is the most common cause of epidemic respiratory disease in infants and young children. RSV infection of airway epithelial cells induces the expression of immune/inflammatory genes through the activation of a subset of transcription factors, including Nuclear Factor-?B (NF-?B). In this study we have investigated the role of the non canonical I?B kinase (IKK)? in modulating RSV-induced NF-?B activation. Our results show that inhibition of IKK? activation results in significant impairment of viral-induced NF-?B-dependent gene expression, through a reduction in NF-?B transcriptional activity, without changes in nuclear translocation or DNA-binding activity. Absence of IKK? results in a significant decrease of RSV-induced NF-?B phosphorylation on serine 536, a post-translational modification important for RSV-induced NF-?B-dependent gene expression, known to regulate NF-?B transcriptional activity without affecting nuclear translocation. This study identifies a novel mechanism by which IKK? regulates viral-induced cellular signaling.
