Transcriptional activation of the interleukin-8 gene by respiratory syncytial virus infection in alveolar epithelial cells: nuclear translocation of the RelA transcription factor as a mechanism producing airway mucosal inflammation

Abstract excerpt

The most common cause of epidemic pediatric respiratory disease, respiratory syncytial virus (RSV), stimulates interleukin-8 (IL-8) synthesis upon infecting airway epithelium, an event necessary for the development of mucosal inflammation. We investigated the mechanism for enhanced IL-8 production in human A549 type II pulmonary epithelial cells. Infection with sucrose-purified RSV (pRSV) produced a...
