1129-VEGFR2在淋巴管萌生与生长的关键作用

from 聊聊Sci

这项研究揭示了VEGFR2受体在淋巴管发芽生长中不可或缺的作用。尽管传统的观点认为VEGFR3是淋巴系统发育的核心,但实验表明,单纯激活VEGFR2虽不能诱导生长,其缺失却会直接导致淋巴内皮细胞失去发芽能力。研究发现,VEGFR2与VEGFR3在细胞表面协同工作,并受PI3Kα信号通路调节,以维持淋巴管扩张与分支生长之间的平衡。通过高精度的条件性基因缺失实验,作者证明了缺乏VEGFR2的细胞在发育过程中会被正常细胞竞争淘汰。这一发现不仅完善了VEGF-C信号转导的理论框架,还为通过靶向VEGFR2药物治疗病理性淋巴管增生提供了新的医疗思路。References:Schoofs H, Zhang Y, Ortsäter H, et al.
