Abstract

Abstract Pulmonary edema induces local and systemic hypoxia in lungs and other tissues and organs, entailing the development of acute respiratory distress syndrome (ARDS). Hypoxia triggers a myriad of pathological responses, including angiogenesis and hyperpermeability of blood vessels in the lung and other tissues. Vascular endothelial growth factor, also named vascular permeability factor (VPF), is one of the key hypoxia-targeted genes. It is probably the most potent VPF in the body. In this article, I will discuss the possibilities and mechanistic insights of blocking the VEGF signaling pathway for treating acute pulmonary edema. In particular, anti-VEGF drugs for treating Covid-19-induced pulmonary edema will be discussed.
