1195-单细胞空间药理学揭示肿瘤基质屏障

from 聊聊Sci

这篇研究介绍了一种名为单细胞空间药理生物学(SSP)的创新实验框架,旨在解决实体瘤治疗中药物递送效率低下的难题。研究人员通过将荧光标记的治疗性抗体注入患者体内,并结合高多重空间蛋白质组学技术,实现了在细胞层面上对药物分布、靶点结合及肿瘤微环境的精确量化。研究发现,在头颈癌和胰腺癌中存在共同的基质屏障,特别是富含成纤维细胞活化蛋白(FAP)的区域和特定的细胞外基质(ECM)结构,会显著阻碍抗体的有效渗透。这一发现揭示了药物耐药性的空间机制,并为优化给药方案及开发精准肿瘤学的空间生物标志物提供了重要依据。通过整合多维度的影像数据,SSP能够以前所未有的分辨率解析药物在人体复杂组织中的真实表现。References:Lu G, Hickey J W, Haist M, et al.
