417-泛癌肿瘤微环境单细胞图谱与异质性分类方案

from 聊聊Sci

这项研究通过构建涵盖26种实体瘤类型的泛癌单细胞转录组图谱,深入解析了肿瘤微环境(TME)的高度复杂性与异质性。研究人员利用超过450万个高质量细胞的数据,根据免疫、骨髓和间质成分的精细组成,将所有肿瘤划分为10个稳定的分型。这些不同的分型在免疫检查点阻断(ICB)疗法的临床响应上表现出显著差异,其中T细胞富集型通常预示着更好的治疗效果。此外,研究揭示了特定巨噬细胞亚群在免疫激活中的关键作用,并识别出与耐药性相关的基质特征。这一分类框架不仅为识别能够从免疫疗法中获益的患者提供了科学依据,还为开发针对特定微环境特征的个性化治疗策略奠定了基础。References: Pan-cancer tumor classification by a holistic tumor microenvironment atlas doi: https://doi.org/10.64898/2025.12.27.696641前往小宇宙评论区与主播互动
