In the aftermath of tissue injury or infection, an efficient resolution mechanism is crucial to allow tissue healing and preserve appropriate organ functioning. Pro-resolving bioactive lipids prevent uncontrolled inflammation and its consequences. Among these mediators, lipoxins were the first described and their pro-resolving actions have been mainly described in immune cells. They exert their actions mostly through formyl-peptide receptor 2 (ALX/FPR2 receptor), a G-protein-coupled receptor whose biological function is tremendously complex, primarily due to its capacity to mediate variable cellular responses. Moreover, lipoxins can also interact with alternative receptors like the cytoplasmic aryl hydrocarbon receptor, the cysteinyl-leukotrienes receptors or GPR32, triggering different intracellular signaling pathways. The available information about this complex response mediated by lipoxins is addressed in this review, going over the different mechanisms used by these molecules to stop the inflammatory reaction and avoid the development of dysregulated and chronic pathologies.
在组织损伤或感染后,一种有效的消退机制对于促进组织愈合和维持器官正常功能至关重要。促消退生物活性脂质可防止炎症失控及其后果。在这些介质中,脂氧素是最早被描述的,其促消退作用主要在免疫细胞中得到描述。它们主要通过甲酰肽受体2(ALX/FPR2受体)发挥作用,这是一种G蛋白偶联受体,其生物学功能极其复杂,主要是因为它能够介导多种细胞反应。此外,脂氧素还可以与其他受体相互作用,如细胞质芳烃受体、半胱氨酰白三烯受体或GPR32,触发不同的细胞内信号通路。本综述阐述了有关脂氧素介导的这种复杂反应的现有信息,探讨了这些分子用于终止炎症反应和避免失调及慢性疾病发展的不同机制。
