黏着斑-细胞骨架系统介导流体剪切力力转导研究进展

Roles of focal adhesion plaques and cytoskeleton in fluid shear stress-induced mechanotransduction

黏着斑是将细胞外基质与细胞骨架联系起来的多蛋白聚集体,在力信号转化为细胞内化学信号、继而引发相应的生理或病理反应过程中发挥着重要作用。本文以黏着斑-细胞骨架系统为重点,总结了黏着斑介导的流体剪切力的力转导过程以及细胞骨架在此过程中的关键作用,介绍了黏着斑中参与胞内信号转导的重要蛋白,并讨论了黏着斑与其他力转导途径的联系,为更好理解剪切力和相关疾病间的关联以及临床药物的研发和疾病的治疗奠定了理论基础。

Focal adhesion plaques （FAPs） are multi-protein aggregates, which act as physical connections between extracellular matrix and cytoskeleton （CSK）. FAPs and CSK play important roles in the conversion of mechanical signals into intracellular chemical signals followed by physiological and pathological responses. With focus on FAPs-CSK system, this review summarized the process of fluid shear stress-induced mechanotransduction and the roles of FAPs and CSK in this process in detail, introduced important proteins in FAPs, discussed the relationship between FAPs and other mechanotransduction pathways. The review established the theoretical foundation for understanding of the relationship between fluid shear stress and shear stress-related diseases, as well as development of clinical drug and treatment of these diseases.
