【摘要】 白介素-33(IL-33)作为IL-1家族中的一种细胞因子,它可以在组织受到损伤时,与特异性受体肿瘤发生抑制蛋白2(ST2)相结合,进而在免疫反应中发挥促炎及抗炎作用。近年来,IL-33的免疫功能已成为许多疾病的研究焦点,尤其在慢性阻塞性肺疾病、哮喘、特发性肺纤维化、阻塞性睡眠呼吸暂停综合征、肺癌等疾病中,均可发现IL-33水平显著升高,但其具体作用机制却不完全一致。因此,本研究通过总结IL-33对常见非感染性肺部疾病的相关影响,为IL-33在肺部疾病中的靶向治疗提供临床依据。

[Abstract] Interleukin-33 (IL-33) as a cytokine in the IL-1 family, can bind to the suppression of tumorigenicity 2 (ST2) when the tissue is damaged, and then play a pro-inflammatory and anti-inflammatory role in the immune response. In recent years, the immune function of IL-33 has become the research focus of many diseases, especially in chronic obstructive pulmonary disease, asthma, idiopathic pulmonary fibrosis, obstructive sleep apnea syndrome, lung cancer and other diseases, it can be found that the level of IL-33 is significantly increased, but its specific mechanism is not completely consistent. Therefore, this study summarizes the effects of IL-33 on common non-infectious lung diseases in order to provide clinical basis for the targeted treatment of IL-33 in lung diseases.

白介素-33(IL-33)是IL-1家族中的一员,它作为一种警报素和细胞因子定位于细胞核中。在肺部,IL-33主要由上皮细胞、肺泡Ⅱ型上皮细胞、内皮细胞、肥大细胞和成纤维细胞分泌表达[1]。在过敏原、污染及香烟烟雾的刺激下,它与其受体肿瘤发生抑制蛋白2(ST2)结合,导致天然和适应性免疫细胞(包括嗜酸性粒细胞、ILC2s、肥大细胞、T细胞、自然杀伤T细胞、巨噬细胞、树突状细胞和造血祖细胞)的活化、迁移和聚集,进而主要以激活IL-4、IL-5和IL-13等2型辅助性T细胞(Th2)发生2型免疫反应[2]。但近年来,已有研究证明IL-33在肺部疾病中还驱动Th1细胞发生1型免疫反应,进而发挥炎症、组织动态平衡和修复的作用[3-5]。本文就IL-33/ST2在慢性阻塞性肺疾病、哮喘、特发性肺纤维化、阻塞性睡眠呼吸暂停综合征、肺癌等非感染性肺部疾病发病机制中的作用进行综述。……
