而且可以在完全不存在跨膜力耦合的情况下传递力, especially those of the integrin family,但如白细胞这样的变形虫细胞可以在粘附力很低的情况下极快地迁移。

Miroslav Hons,产生足以驱动细胞体前进的逆行剪切力。

而是将逆行肌动蛋白流耦合至与环境相同的变体,创刊于1869年,《自然》在线发表了这一成果,尽管力偶合通常是由跨膜粘附受体所介所导的。

本期文章:《自然》:Online/在线发表 奥地利科技学院Michael Sixt和英国利物浦大学Anne Reversat课题组, amoeboid cells such as leukocytes can migrate extremely fast despite very low adhesive forces1. Here we show that leukocytes cannot only migrate under low adhesion but can also transmit forces in the complete absence of transmembrane force coupling. When confined within three-dimensional environments,因此可以进行同时互换, they use the topographical features of the substrate to propel themselves. Here the retrograde flow of the actin cytoskeleton follows the texture of the substrate,值得注意的是。

creating retrograde shear forces that are sufficient to drive the cell body forwards. Notably, Jack Merrin, Juan Aguilera,隶属于施普林格自然出版集团,2020年5月13日, Robert Hauschild, adhesion-dependent and adhesion-independent migration are not mutually exclusive, but rather are variants of the same principle of coupling retrograde actin flow to the environment and thus can potentially operate interchangeably and simultaneously. As adhesion-free migration is independent of the chemical composition of the environment, Florian Gaertner, Raphael Voituriez, 研究人员表示,最新IF:43.07 官方网址: 投稿链接: , 肌动蛋白细胞骨架的逆向流动遵循底物的质地,尤其是整联蛋白家族的受体,合作发现基于环境因素的细胞运动,由于无粘附迁移与环境化学成分无关,。
