The role of hypoxia in pulmonary vascular diseases: a perspective

Abstract

From the discovery of hypoxic pulmonary vasoconstriction, responses to hypoxia have been considered as representative for the many alterations in lung vessels that occur in several chronic lung diseases, including pulmonary hypertension, interstitial pulmonary fibrosis, acute respiratory distress syndrome, and chronic obstructive pulmonary disease. An essential part of preclinical research to explain the pathobiology of these diseases has been centered on the exposure of small and large animals to hypoxia. This review aims to summarize pivotal results of clinical and preclinical research on hypoxia, which still have important implications for researchers today.
