Human β-definsin-2（hBD-2）is mainly induced by bacterial factors and pro-inflammation mediators in epithelial cells.As the major cause of community-acquired pneumonia,whether Streptococcus pneumoniae（S.pneumoniae）stimulation induces hBD-2 expression in airway epithelial cells is elusive.In this study,we found that S.pneumoniae stimulation induced hBD-2 expression in a time-and concentration-dependent manner in primary human airway epithelial cells.To further reveal the mechanism of S.pneumoniae i...
