1607-人乳头瘤病毒相关口咽癌的细胞空间序位与免疫逃逸机制

from 聊聊Sci

这份研究利用单细胞空间转录组学和单细胞测序技术,深入剖析了人乳头瘤病毒相关口咽癌(HPV-OPSCC)的复杂空间组织结构。研究人员发现了两类具有不同功能和位置的趋化因子病灶:CXCL9/10/11病灶富集抗肿瘤T细胞,而CXCL8病灶则处于由缺氧驱动的免疫抑制状态。分析表明,缺氧环境与IFN-γ信号不仅共同塑造了病灶的多样性,还诱导癌细胞进入HPVoff(HPV基因表达缺失)的衰老状态,从而规避免疫攻击。通过临床数据验证,研究进一步确认CXCL8介导的免疫逃逸机制与患者生存率降低密切相关。该成果揭示了肿瘤微环境如何通过局部空间重组来实现免疫抵抗,为精准治疗提供了新视角。References:Sievers C, Robbins Y, Craveiro M, et al.
