概括

宫腺癌 (ADC) 呈现出独特的细胞群和免疫抑制瘤微环境,与状细胞癌 (SCC) 不同. 这些ADC特征预测淋巴结转移,并有助于其侵略性.

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:

宫腺癌 (ADC) 比状细胞癌 (SCC) 更具攻击性.
瘤免疫微环境 (TIME) 和异质性显著影响癌症的进展和治疗反应.
时间的差异和ADC和SCC之间的异质性仍然不太了解.

研究的目的:

与状细胞癌 (SCC) 相比,研究宫腺癌 (ADC) 中明显的时间和细胞异质性.
为了识别特定的细胞群和分子途径驱动ADC的侵略性.
探索已识别的ADC特征对淋巴结转移的预测潜力.

主要方法:

在11个ADC和4个SCC瘤组织样本上进行了单细胞RNA测序.
免疫化学和多重免疫光试验被用于验证.
进行生物信息分析以确定细胞子集群和信号通路.

主要成果:

与SCC相比,ADC显示出独特的上皮细胞子集群,包括Epi_10_CYSTM1,与SCC相比,其茎度升高和恶性特征.
ADC表现出一种免疫抑制的TIME,富含调节性T细胞 (Tregs) 和促进瘤的中性粒细胞.
在Epi_10_CYSTM1集群通过ALCAM-CD6信号招募Tregs,Tregs通过TGFβ信号相互增强这个集群中的干性.
确定了Epi_10_CYSTM1集群作为宫癌患者淋巴结转移的预测因素.

结论:

特定于ADC的细胞群在建立高度免疫抑制的微环境中起着至关重要的作用.
这些独特的特征有助于ADC与SCC相比,ADC观察到的攻击性增加和预后较差.
准已识别的信号通路和细胞群可能为ADC提供新的治疗策略.

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...
