HIF1-α upregulation induces proinflammatory factors to boost host killing capacity after exposure.

HIF1-α is an important transcription factor in the regulation of the immune response. The protective function of HIF1-α in the host epithelial immune response to requires further clarification. In this study we demonstrated the effect of upregulation of HIF1-α expression in A549 cells and mouse airway cells exposed to . The killing capacity was enhanced by boosting proinflammatory factors both and . Moreover, airway inflammation was reduced in the HIF1-α-upregulated mice. We identified a protective role for HIF1-α in anti- immunity. Modulation of HIF1-α might be a target for the development of aspergillosis therapy.
