599-Foxf2通过Tie2信号通路维持脑内皮细胞功能

from 聊聊Sci

这项研究探讨了Foxf2转录因子在维持脑内皮细胞功能以及预防脑小血管病中的关键作用。通过对小鼠模型和人类诱导多能干细胞的分析,研究人员发现该因子能直接调节Tie2信号通路,进而保护血脑屏障的完整性并调节脑血流量。实验数据表明,当Foxf2缺失时,会导致内皮功能障碍、血管渗漏以及中风后的组织损伤加剧。此外,研究还证实使用药物激活Tie2可以有效挽救因基因缺失引起的血管缺陷。这些发现为理解中风和血管性痴呆的遗传机制提供了新视角,并为治疗脑血管疾病指明了潜在的靶点。References: Todorov-Völgyi K, González-Gallego J, Müller S A, et al.
