近年来,微生物对肿瘤生长和转移的影响引起了人们的极大关注。肺癌的发病机制和进展与呼吸道细菌负荷的增加以及细菌群落的变化有关,因为微生物群以多种方式影响肿瘤,包括癌变、转移、血管生成和治疗。微生物群可能通过改变代谢和免疫反应,促进炎症和增加毒性作用来增加肿瘤易感性。微生物群可以通过改变多种细胞信号通路来调节肿瘤转移,并通过血管内皮生长因子(VEGF)、内皮细胞(ECs)、炎症因子和炎症细胞参与肿瘤血管生成。肿瘤血管生成不仅维持肿瘤在原发部位的生长,而且促进肿瘤的转移和侵袭。因此,血管生成是微生物与肿瘤相互作用的重要介质。微生物群也在抗肿瘤治疗中发挥作用。抗生素引起的微生物群的改变可以调节肿瘤的生长和转移。此外,微生物群还影响肿瘤免疫治疗和化疗的疗效和毒性。最后,讨论了肺癌的危险因素空气污染对微生物的影响以及呼吸道微生物在空气污染对肺癌影响中的可能作用。
Recently, the impact of microorganisms on tumor growth and metastasis has attracted great attention. The pathogenesis and progression of lung cancer are related to an increase in respiratory bacterial load as well as changes in the bacterial community because the microbiota affects tumors in many ways, including canceration, metastasis, angiogenesis, and treatment. The microbiota may increase tumor susceptibility by altering metabolism and immune responses, promoting inflammation, and increasing toxic effects. The microbiota can regulate tumor metastasis by altering multiple cell signaling pathways and participate in tumor angiogenesis through vascular endothelial growth factors (VEGF), endothelial cells (ECs), inflammatory factors and inflammatory cells. Tumor angiogenesis not only maintains tumor growth at the primary site but also promotes tumor metastasis and invasion. Therefore, angiogenesis is an important mediator of the interaction between microorganisms and tumors. The microbiota also plays a part in antitumor therapy. Alteration of the microbiota caused by antibiotics can regulate tumor growth and metastasis. Moreover, the microbiota also influences the efficacy and toxicity of tumor immunotherapy and chemotherapy. Finally, the effects of air pollution, a risk factor for lung cancer, on microorganisms and the possible role of respiratory microorganisms in the effects of air pollution on lung cancer are discussed.
