在全身血管系统中,缺氧会引起血管扩张,而肺动脉则会因缺氧而收缩。这种独特反应背后的机制已经被研究了50多年,并且仍然是一个有很大争议的话题。在过去的20年里,人们普遍认为细胞内钙浓度的增加和活性氧(ROS)生成的变化在肺血管对缺氧的反应中起着关键作用。然而,关于缺氧时ROS的增加或减少,ROS的来源,以及ROS的变化可能影响细胞内钙的机制,反之亦然,存在争议。本文将讨论PASMCs中[Ca2+]i和ROS的调节机制,以及暴露于急性缺氧时ROS和Ca2+信号的相互作用。
In contrast to the systemic vasculature, where hypoxia causes vasodilation, pulmonary arteries constrict in response to hypoxia. The mechanisms underlying this unique response have been the subject of investigation for over 50 years, and still remain a topic of great debate. Over the last 20 years, there has emerged a general consensus that both increases in intracellular calcium concentration and changes in reactive oxygen species (ROS) generation play key roles in the pulmonary vascular response to hypoxia. Controversy exists, however, regarding whether ROS increase or decrease during hypoxia, the source of ROS, and the mechanisms by which changes in ROS might impact intracellular calcium, and vice versa. This review will discuss the mechanisms regulating [Ca2+]i and ROS in PASMCs, and the interaction between ROS and Ca2+ signaling during exposure to acute hypoxia.
