Ghrelin protects against lipopolysaccharide-induced acute respiratory distress syndrome through the PI3K/AKT pathway

Pulmonary endothelial barrier dysfunction is a major pathophysiology observed in acute respiratory distress syndrome (ARDS). Ghrelin, a key regulator of metabolism, has been shown to play protective roles in the respiratory system. However, its effects on lipopolysaccharide (LPS)-induced pulmonary endothelial barrier injury are unknown. In this study, the effects of ghrelin on LPS-induced ARDS and endothelial cell injury were evaluated in vivo...
