Abstract:
Bronchopulmonary dysplasia(BPD)is a chronic respiratory system disease that causes respiratory failure and death in premature infants, and hyperoxic exposure is the main risk factor for its occurrence.Cellular senescence describes a state of cell cycle blockade, and in recent years studies have confirmed that exposure to hyperoxia can cause cellular senescence.Cellular senescence plays a crucial role in the development of the lung epithelium, lung interstitium, pulmonary vasculature, and airways, and abnormal development of these tissues is associated with the development of BPD.Therefore, this paper takes cellular senescence and BPD as the starting point to review the mechanism of hyperoxia-induced cellular senescence in the occurrence and development of BPD and the anti-aging drugs currently applied in clinical practice, in order to provide a new direction for the prevention and treatment of BPD.
