低氧诱导因子(HIF)是对低氧适应性反应至关重要的转录因子。缺氧和炎症之间也存在重要联系,并且HIF与对各种损伤的免疫反应失调有关。尽管缺氧在组织创伤中普遍存在,特别是涉及肺,但仍然缺乏研究HIF在临床相关损伤模型中的作用的研究。在此,我们总结了HIF-1α对肺血管、代谢、炎症和细胞凋亡的影响,并回顾了HIF在直接肺损伤(包括肺挫伤、酸吸入、肺炎和COVID-19)中的作用。我们目前的数据表明,HIF-1α在支持和反对其在肺损伤急性炎症反应传播中的作用是适应性的还是有害的。最后,我们讨论了在现代重症监护病房作为一类新的治疗药物的药物调制的HIF的潜力。
Hypoxia-inducible factors (HIFs) are transcription factors critical for the adaptive response to hypoxia. There is also an essential link between hypoxia and inflammation, and HIFs have been implicated in the dysregulated immune response to various insults. Despite the prevalence of hypoxia in tissue trauma, especially involving the lungs, there remains a dearth of studies investigating the role of HIFs in clinically relevant injury models. Here, we summarize the effects of HIF-1α on the vasculature, metabolism, inflammation, and apoptosis in the lungs and review the role of HIFs in direct lung injuries, including lung contusion, acid aspiration, pneumonia, and COVID-19. We present data that implicates HIF-1α in the context of arguments both in favor and against its role as adaptive or injurious in the propagation of the acute inflammatory response in lung injuries. Finally, we discuss the potential for pharmacological modulation of HIFs as a new class of therapeutics in the modern intensive care unit.
