548-CCL3驱动促癌中性粒细胞跨癌种生存与生长

from 聊聊Sci

这项研究开发了一种新型单细胞RNA测序分类器,旨在解决由于mRNA含量低而导致的中性粒细胞在数据中被错误过滤的难题。通过该工具,研究人员发现肿瘤相关中性粒细胞(TANs)的丰度是癌症预后的独立预测指标,并跨物种定义了从“年轻”状态向CCL3高表达“年老”状态发展的分化轨迹。实验证明,CCL3-CCR1信号轴在缺氧环境下通过增强细胞存活,维持了具有促癌功能的终末期中性粒细胞群体。这些发现不仅揭示了中性粒细胞在不同癌症中的转录保守性,还为开发针对髓系细胞的新型免疫疗法提供了靶点。该研究强调了CCL3作为泛癌预后标志物的潜力,并为理解肿瘤微环境中的免疫调节提供了新视角。References: Bolli E, Wirapati P, Hicham M, et al.
