内皮YAP/TAZ活动由血液流动调节,抑制减少炎症和动脉样硬化. 向整合蛋白-Gα13-RhoA-YAP通路为动脉样硬化提供了一个新的治疗策略.
科学领域:
- 心血管生物学
- 疾病的分子机制
- 机械生物学
背景情况:
- 河马途径效应器YAP (Yes相关蛋白) 和TAZ (具有PDZ结合动机的转录协活性剂) 介导机械刺激.
- YAP/TAZ在血流诱导的机械传导和动脉样硬化病变中的作用尚不完全理解.
研究的目的:
- 通过血液流动模式研究内皮YAP/TAZ活动的调节.
- 确定YAP/TAZ在动脉样硬化的作用,并确定潜在的治疗点.
主要方法:
- 在不同的剪切应力条件下研究了内皮YAP/TAZ活性.
- 使用内体模型 (ApoE-/-小鼠) 具有内皮特异性YAP过度表达和Yap倒置 (CRISPR/ Cas9).
- 检查了现有的抗动脉硬化剂和整合素激活对斑块形成的影响.
主要成果:
- 乙烯干扰流增加了YAP/TAZ活性,而乙烯保护单向剪切应力则抑制了它.
- 单向剪切应力激活整合素,抑制RhoA和抑制YAP/TAZ.
- 在体内抑制YAP/ TAZ可减少炎症,单细胞透,并延缓动脉样硬化的发展.
- 类药物抑制YAP/TAZ,并向整合蛋白-Gα13-RhoA-YAP通路,减少斑块的形成.
结论:
- 内皮YAP/TAZ活动由血液流动模式差异调节,影响动脉样硬化.
- 整合蛋白-Gα13-RhoA-YAP信号通路是动脉样硬化中血动力学诱导的机制传导的关键介质.
- 抑制这种途径为动脉样硬化治疗提供了一个有前途的新疗法.

Integrins
Some ECM proteins assemble into a basement membrane to which the remaining components adhere. Proteoglycans typically form the bulk of the ECM while fibrous proteins, like collagen,...
Activation of Integrins
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding...
