肺癌驱动基因与PD-1/PD-L1信号通路相互作用在非小细胞肺癌发生发展中的研究进展

程序性死亡分子1(programmed death 1,PD-1)/程序性死亡分子1配体(programmed death 1 ligand,PD-L1)通路是免疫调节的重要通路,而这一通路在肿瘤组织中存在着异常激活,提示PD-1/PD-L1通路可能参与了肿瘤的免疫逃逸过程.肿瘤驱动基因在非小细胞肺癌(non-small cell lung cancer,NSCLC)的发生发展中发挥着重要的作用,而对于肿瘤免疫逃逸的建立同样具有潜在的作用,这提示肿瘤驱动基因通路与PD-1/PD-L1通路可能存在相互作用.本文将对目前关于PD-L1与主要的肺癌驱动基因表皮生长因子受体基因(epidermal growth factor receptor,EGFR)、鼠类肉瘤病毒癌基因(Kirsten rate sarcoma viral oncogene homolog,KRAS)及棘皮微管样蛋白4-间变性淋巴瘤激酶融合基因(echinoderm microtubuleassociated protein-like 4-anaplastic lymphoma kinase,EML4-ALK)之间的关系及调控进行综述,总结肺癌驱动基因及PD-1/PD-L1通路相互作用在非小细胞肺癌发生发展中的作用.

Advances of the Role of Lung Cancer Driver Gene and PD-1/PD-L1 Pathway Interaction in the Tumorigenesis and Progression of Non-small Cell Lung Cancer

Programmed death 1 (PD-1) and programmed death 1 ligand (PD-L1) pathway is a key mechanism of immune regulation, and its abnormal activation in tumor tissues suggests that PD-1/PD-L1 pathway may participate in the regulation of tumor immune escape. Driver gene mutation which is known as a key factor in the tumorigenesis of non-small cell lung cancer (NSCLC), was also reported to play a important role in the process of tumor immune escape. It indicates that there is an interaction between driver gene and PD-1/PD-L1 pathway. The purpose of this paper is to review the relationship be-tween PD-1/PD-L1 pathway and lung cancer driver gene, such as epidermal growth factor receptor (EGFR), Kirsten rate sarcoma viral oncogene homolog (KRAS) and echinoderm microtubuleassociated protein-like 4 - anaplastic lymphoma kinase (EML4-ALK) and to summarize the role of lung cancer driver gene and PD-1/PD-L1 pathway interaction in the tumorigenesis and progres-sion of NSCLC.
