科学领域:
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
- 分子生物学分子生物学
背景情况:
- 非小细胞肺癌 (NSCLC) 是癌症相关死亡的主要原因.
- 了解PD-1/PD-L1表达的生物学功能和临床意义对于开发向疗法至关重要.
- 像PD-1/PD-L1这样的免疫检查点和EGFR这样的瘤性途径之间的相互作用是NSCLC的活跃研究领域.
研究的目的:
- 研究NSCLC组织中PD-1和PD-L1的表达模式.
- 在NSCLC中确定PD-1/PD-L1表达的临床意义.
- 在NSCLC中探索PD-1/PD-L1表达和表皮生长因子受体 (EGFR) 状态之间的相关性.
主要方法:

- 用聚合酶链反应 (PCR) 来评估EGFR的表现.
- 使用后勤回归分析来评估PD-1/PD-L1和EGFR之间的关联.
主要成果:
- 与正常肺组织相比,NSCLC组织中的PD-1和PD-L1表达显著更高 (P<0.05).
- 对于PD-L1和PD-1的阳性率分别为53.70%和55.56%.
- PD-1/PD-L1表达与淋巴结转移和TNM分期相关 (P<0.05).
结论:
- 在NSCLC患者中,高EGFR突变风险与积极的PD-1/PD-L1表达密切相关.
- PD-1/PD-L1可以作为在NSCLC中EGFR突变的预测生物标志物.
- 这些发现突显了针对EGFR突变NSCLC中的PD-1/PD-L1途径的潜力.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
