Fig. 4From: IRF4 affects the protective effect of regulatory T cells on the pulmonary vasculature of a bronchopulmonary dysplasia mouse model by regulating FOXP3Mechanism diagram. Hyperoxia increases IRF4 levels and affects the protective effect of Tregs on the proliferation of PVECs and pulmonary vascular development by inhibiting FOXP3 levels, which ultimately leads to impaired pulmonary vascular development and BPDBack to article page
