1178-SPAC-seq与TARDIS:空间功能基因组学筛选平台

from 聊聊Sci

研究人员开发了名为 SPAC-seq 的高通量空间 CRISPR 筛选技术,并配套开发了统计分析工具 TARDIS,旨在揭示基因功能与组织空间表型之间的因果联系。该系统能够同时捕捉全转录组信息与空间分辨率下的 sgRNA 库,从而在单细胞层面解析复杂的肿瘤微环境。通过应用此技术,研究揭示了 Icam1 缺失如何通过诱导免疫抑制生态位来促进肿瘤转移。在 CD8+ T 细胞 的研究中,该工具成功识别出 SPP1-CD44 轴是限制免疫活性的关键抑制机制,并发现转录因子 Bhlhe40 通过调节趋化因子受体来精准调控 T 细胞的空间分布。总之,该框架为在多种疾病背景下探索空间功能基因组学提供了一种强大的手段。References:Zhang H, Zhang Z, Wang P, et al.
