细胞膜和细胞骨架在细胞受力过程中的保护作用

力作用下的细胞保护反应是细胞机械力转导研究中的一个重要领域。细胞膜维持细胞内离子平衡，并通过牵张活化离子通道和机械力敏感酶调控力诱导的细胞骨架重排对细胞骨架产生保护作用；而细胞骨架给细胞膜提供结构支撑、加强受力部分的皮层网络结构、调控机械力敏感离子通道，在受力破坏后的细胞膜重新封闭的过程中也发挥着潜在的作用。就细胞膜和细胞骨架在细胞受力过程中的保护作用进行综述。

Cytoproteclive response of cytoskeleton and plasma membrane to forces

Cytoprotective responses to forces is an important subset of mechanotransduction. The plasma membrane protects the cytoskeleton by maintenance of intracellular ionic balance and can modulate force-induced cytoskeletal rearrangements by stretch-activated ion channels and mechanosensitive enzymes. Conversely, the cytoskeleton protects the plasma membrane by providing structural support, reinforcement of the cortical framework at sites of force application, modulation of mechanosensitive ion channels and by potentially contributing to the membrane resealing process after mechanical rupture. We focus the roles of cytoskeleton and plasma membrane to physical stresses in this paper.
