概括

了解非小细胞肺癌 (NSCLC) 的分子亚型揭示了不同的免疫格局. 靠近性炎症 (PI) 亚型表现出激活的免疫力,而靠近性增殖 (PP) 亚型表现出免疫抑制的微环境,指导个性化免疫治疗策略.

科学领域:

在瘤学瘤学.
免疫学免疫学免疫学
基因组学就是基因组学.

背景情况:

非小细胞肺癌 (NSCLC) 表现出分子异质性,影响治疗反应.
了解NSCLC亚型的免疫微环境 (TME) 对于克服对免疫检查点抑制剂的抵抗至关重要.
目前对NSCLC分子亚型的免疫特征的知识仍然不完整.

研究的目的:

通过多omics方法研究NSCLC分子亚型的免疫景观.
为了将分子亚型与免疫细胞透,TME特征和临床结果相关联.
确定NSCLC个性化免疫治疗的潜在治疗点.

主要方法:

对NSCLC组织的多omics分析,包括瘤透白细胞 (TILs) 的流动细胞计,RNA测序,整个外基因组测序和代谢学.
分子亚型 (腺癌的TRU,PP,PI;状细胞癌的LUSQ) 与免疫学和临床病理学数据的相关性.
评估三级淋巴体结构,细胞毒性标志物,葡萄糖载体1 (GLUT1) 表达和乳酸水平.

主要成果:

临近炎症 (PI) 亚型显示TILs增加,激活免疫反应和高细胞毒性标志物.
临近增殖 (PP) 亚型的预后较差,GLUT1表达升高,乳酸积累,表明免疫抑制的TME.
最终呼吸单元 (TRU) 亚型表现出低恶性和"冷"免疫表型;状细胞癌 (LUSQ) 亚型缺乏明显的免疫特征.

结论:

NSCLC的分子亚型具有不同的免疫格局,影响患者的预后和治疗反应.
由于其激活的免疫TME,PI亚型可能受益于免疫检查点抑制剂.
在PP亚型中准糖解可能会将免疫抑制的TME转化为抗瘤的TME,从而改善NSCLC治疗.

The Tumor Microenvironment

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Tumor Immunotherapy

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
