506-scRank:利用单细胞调控网络预测药物响应细胞类型

from 聊聊Sci

这项研究介绍了一种名为 scRank 的新型计算方法,旨在通过单细胞转录组测序技术识别药物作用的精确靶细胞类型。传统分析往往掩盖了组织内部的细胞异质性,而该研究通过构建基因调控网络,深入分析了不同细胞亚群对治疗的敏感性差异。研究人员利用该方法成功锁定了治疗抑郁症的氟西汀所针对的特定神经元亚群,并验证了其在髓母细胞瘤和心肌梗死治疗中的应用。实验进一步证实,丹参酮 IIA 通过直接结合并抑制巨噬细胞中的 CTSB 蛋白来发挥药理作用。这些发现不仅阐明了复杂疾病的药物作用机制,也为精准医学和新药研发提供了重要的辅助决策工具。References: scRank infers drug-responsive cell types from untreated scRNA-seq data using a target-perturbed gene regulatory networkLi, Chengyu et al.Cell Reports Medicine, Volume 5, Issue 6, 101568前往小宇宙评论区与主播互动
