Upregulated TSP1 and CD47 Expression in the Lung in Nitrofen-induced Congenital Diaphragmatic Hernia

Hajime TakayasuKitasato University. University of Tsukuba.Japan Pediatrics InternationalPediatr Int 2022; DOI: 10.1111/ped.15447 AbstractBackground: Persistent pulmonary hypertension remains a major cause of mortality and morbidity in congenital diaphragmatic hernia (CDH). The secreted glycoprotein thrombospondin-1 (TSP1), a ligand for receptor CD47, is widely expressed on both systemic and pulmonary vascular cells. TSP1-CD47 signaling has been reported to be one
