232-ESCC转移中GPR116+周细胞的免疫抑制作用

from 聊聊Sci

这篇文章主要聚焦于食管鳞状细胞癌(ESCC)转移的机制研究,特别强调肿瘤微环境(TME)中一种名为GPR116+周细胞的亚群。通过多组学技术,研究人员发现GPR116+周细胞在转移性癌症中数量显著增加,并表现出最强的对外发送信号,尤其与癌细胞的相互作用最为密切。此外,研究确定转录因子 PRRX1 驱动了这种促转移性GPR116+周细胞的分化,而这些细胞通过分泌 EGFL6 蛋白,结合癌细胞上的 整合素 β1,进而激活NF-κB信号通路,促进癌症的上皮-间质转化(EMT)和转移。最后,该研究还发现GPR116+周细胞具有免疫抑制特性,并提出联合使用整合素 β1 抑制剂(如volociximab或ATN-161)和αPD-1检查点抑制剂,可作为治疗晚期ESCC的有效联合疗法。References: Pei X, Liu Z, Tang L, et al.
