Hypoxic Pulmonary Vasoconstriction in Isolated Mouse Pulmonary Arterial Vessels
Experimental physiology(2018)
摘要
What is the central question of this study? Hypoxic pulmonary vasoconstriction has never been characterized in isolated mouse pulmonary arteries of different generations in detail. What is the main finding and its importance? We found that only small intrapulmonary arteries (80–200 μm in diameter) exhibit hypoxic pulmonary vasoconstriction. The observed response was sustained, significantly potentiated by depolarization‐induced preconstriction and not dependent on the endothelium or TRPC6 channels.
