| Research Abstract |
The main cause of death in influenza viral infection is secondary bacterial pneumonia. The expression of SET domain bifurcated 2 (SETDB2), an enzyme which leads to gene depression, was increased in both macrophages and bronchial epithelial cells, followed bytype-I interferon (an essential cytokine against viral infection) and influenza viral stimulation itself. The expression of SETDB2is type-I interferon (IFN-I) dependent, and IFN-I receptor knockout mice improved a significant survival compared with wild-type mice in secondary bacterial infectious model. There results suggest that SETDB2 has the potential to be a clinical key to prevent secondary bacterial pneumonia following influenza viral infection.
