肌动蛋白聚合提供驱动力,以辅助几种涉及将质膜拉入细胞的过程,包括吞噬作用、大型病毒进入细胞以及胞吞作用。在胞吞作用中,在高膜张力或高膨压条件下,肌动蛋白聚合尤为重要。近期的建模研究已经表明肌动蛋白聚合如何在胞吞位点周围产生力的分布,并探究了这些力如何影响形状动态;实验越来越详细地揭示了胞吞机制的结构,并证明了肌动蛋白组装和膜曲率之间的关键反馈相互作用。在此,我们对这些发现进行综述,并为未来研究提出方向。
Actin polymerization provides driving force to aid several types of processes that involve pulling the plasma membrane into the cell, including phagocytosis, cellular entry of large viruses, and endocytosis. In endocytosis, actin polymerization is especially important under conditions of high membrane tension or high turgor pressure. Recent modeling efforts have shown how actin polymerization can give rise to a distribution of forces around the endocytic site, and explored how these forces affect the shape dynamics; experiments have revealed the structure of the endocytic machinery in increasing detail, and demonstrated key feedback interactions between actin assembly and membrane curvature. Here we provide a perspective on these findings and suggest avenues for future research.
