Lipoxins (LXs) are a class of endogenous bioactive lipid mediators that are involved in the regulation of inflammation. They exert immunomodulatory effects by regulating the behaviour of various immune cells, including neutrophils, macrophages, and T and B cells, by promoting the clearance of apoptotic neutrophils. This helps to dampen inflammation and promote tissue repair. LXs regulate the expression of many inflammatory genes by modulating the levels of transcription factors, such as nuclear factor κB (NF-κB), activator protein-1 (AP-1), nerve growth factor-regulated factor 1A binding protein 1 (NGF), and peroxisome proliferator activated receptor γ (PPAR-γ), which are elevated in various diseases, such as respiratory tract diseases, renal diseases, cancer, neurodegenerative diseases, and viral infections. Lipoxin-mediated signaling is involved in chronic inflammation, cancer, diabetes-associated kidney disease, lung injury, liver injury, endometriosis, respiratory tract diseases, neurodegenerative diseases, chronic cerebral hypoperfusion, and retinal degeneration. In this study, we systematically investigated the intricate network of lipoxin signaling by analyzing the relevant literature. The resulting map comprised 467 molecules categorized as activation/inhibition, enzyme catalysis, gene and protein expression, molecular associations, and translocation events. This map serves as a valuable resource for understanding the complexity of lipoxin signaling and its impact on various cellular functions.
脂氧素(LXs)是一类内源性生物活性脂质介质,参与炎症的调节。它们通过调节各种免疫细胞的行为发挥免疫调节作用,包括中性粒细胞、巨噬细胞、T 和 B 细胞,并促进凋亡中性粒细胞的清除。这有助于抑制炎症并促进组织修复。LXs 通过调节转录因子的水平来调节许多炎症基因的表达,如核因子 κB(NF-κB)、激活蛋白-1(AP-1)、神经生长因子调节因子 1A 结合蛋白 1(NGF)和过氧化物酶体增殖物激活受体 γ(PPAR-γ),这些转录因子在各种疾病中升高,如呼吸道疾病、肾脏疾病、癌症、神经退行性疾病和病毒感染。脂氧素介导的信号转导参与慢性炎症、癌症、糖尿病相关肾病、肺损伤、肝损伤、子宫内膜异位症、呼吸道疾病、神经退行性疾病、慢性脑低灌注和视网膜变性。在这项研究中,我们通过分析相关文献系统地研究了脂氧素信号的复杂网络。由此产生的图谱包含 467 种分子,分为激活/抑制、酶催化、基因和蛋白质表达、分子关联和易位事件。该图谱为理解脂氧素信号的复杂性及其对各种细胞功能的影响提供了有价值的资源。
