1273-GZMK表达反映T细胞分化效率并预测免疫治疗效果

from 聊聊Sci

这项研究揭示了GZMK(颗粒酶K)在头颈部鳞状细胞癌免疫治疗中的核心作用。通过对患者T细胞的单细胞测序和克隆分析,研究人员发现GZMK的表达是新入驻肿瘤的效应记忆T细胞的显著标志。研究表明,治疗前肿瘤基质中GZMK+ T细胞的比例及其分化效率,能够有效预测患者对新辅助免疫治疗的病理缓解程度。此外,团队开发的一种40基因GZMK特征评分在多种癌症类型中均表现出极强的预后价值,显著优于现有的生物标志物。该发现不仅深化了对T细胞发育层级的理解,还为临床提供了更精准的个性化治疗预测工具。References:Sievers, C.M., Chang, TG., Robbins, Y. et al.
