The discovery of carotid bodies as sensory receptors for detecting arterial blood oxygen levels, and the identification and elucidation of the roles of hypoxia-inducible factors (HIFs) in oxygen homeostasis have propelled the field of oxygen biology. This review highlights the gas-messenger signaling mechanisms associated with oxygen sensing, as well as transcriptional and non-transcriptional mechanisms underlying the maintenance of oxygen homeostasis by HIFs and their relevance to physiology and pathology.
颈动脉体作为检测动脉血氧水平的感觉受体的发现,以及缺氧诱导因子(HIFs)在氧稳态中的作用的鉴定和阐明,推动了氧生物学领域的发展。本综述重点介绍了与氧感知相关的气体信使信号传导机制,以及HIFs维持氧稳态的转录和非转录机制及其与生理和病理的相关性。
