概括

研究人员发现了一种新的细胞类型,CD4+Tex-pre细胞,在口腔状细胞癌 (OSCC) 中促进淋巴结转移. 这些细胞创造了一个免疫抑制的环境,加剧了癌症的传播,并可能引导OSCC患者的治疗决策.

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:

口腔状细胞癌 (OSCC) 经常转移到淋巴结 (LNs).
对于LNs中前转移性的细胞组成的了解很少.
了解这个利基对于预测和预防转移至关重要.

研究的目的:

在OSCC中调查前转移性LNs的细胞格局.
为了识别涉及LN转移的新型细胞群.
阐明这些细胞在免疫抑制和转移进展中的作用.

主要方法:

建立前转移性LNs的小鼠模型.
人类OSCC患者的单细胞RNA测序LNs.
鉴定细胞群的in silico和in vivo验证.
收养转移的实验.
RNA范围染色和大量RNA测序分析.

主要成果:

在预耗尽状态下识别表达MIR155HG (CD4+Tex-pre细胞) 的CD4+T细胞子集.
CD4+Tex-pre细胞富含瘤排水的前转移性LNs,并随转移而增加.
这些细胞通过加剧免疫抑制来促进LN转移.
CD4+Tex-pre细胞透与淋巴转移相关,可能有助于治疗.

结论:

CD4+Tex-pre细胞在塑造OSCC LNs中的免疫抑制性前转移性利基中发挥着重要作用.
这些细胞是LN转移进展的关键驱动因素.
这些发现为预测转移和指导OSCC治疗策略提供了潜在的生物标志物.

Metastasis

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
