Mitochondrial DNA-driven senescence-associated secretory phenotype promotes the development of bronchopulmonary dysplasia

We uncovered a novel pathway in bronchopulmonary dysplasia (BPD) development, where mitochondrial dysfunction triggers mtDNA release, activating the cGAS-STING pathway and regulating the senescence-associated secretory phenotype (SASP). This cascade impacts lung epithelial cell function in oxidant-induced injury, providing new insights into BPD pathogenesis.
