Oxygen-Independent Stabilization of Hypoxia Inducible Factor (HIF)-1 during RSV Infection

摘要

BackgroundHypoxia-inducible factor 1 (HIF)-1α is a transcription factor that functions as master regulator of mammalian oxygen homeostasis. In addition, recent studies identified a role for HIF-1α as transcriptional regulator during inflammation or infection. Based on studies showing that respiratory syncytial virus (RSV) is among the most potent biological stimuli to induce an inflammatory milieu, we hypothesized a role of HIF-1α as transcriptional regulator during infections with RSV.
