459-人类遗传学指导下的CARD9抑制剂研发

from 聊聊Sci

这项研究利用人类遗传学揭示了 CARD9 蛋白在免疫炎症中的关键作用,并据此开发了新型小分子抑制剂。研究人员发现 CARD9 的特定基因变异能减少克罗恩病风险,因此通过高通量筛选和结构优化,成功合成了高效的苯二氮卓类化合物。这些抑制剂能特异性阻断 CARD9 信号通路,在体外细胞实验中显著减少了促炎细胞因子的产生。通过对人源化小鼠模型的体内实验,证实了其中名为 6 号化合物的药物能有效缓解系统性炎症。该成果为治疗克罗恩病等炎症性肠病提供了一种比传统免疫抑制剂更精准、更安全的靶向治疗方案。这项工作不仅展示了从基因发现到药物开发的完整流程,也为难以成药的蛋白质研究提供了新的结构思路。References: Rush J S, Wertheimer J D, Goldberg S D, et al.
