The slender shape of axons makes them uniquely susceptible to mechanical stress. In this issue, Pan, Hu et al. (https://doi.org/10.1083/jcb.202206046) use a microfluidic axon-on-chip device to reveal how actomyosin protects axons from mild mechanical stress, by transiently adopting a beaded shape that helps limit the spread of damaging calcium waves.
轴突的细长形状使它们特别容易受到机械应力的影响。在本期杂志中,Pan、Hu 等人(https://doi.org/10.1083/jcb.202206046)使用微流控轴突芯片装置揭示了肌动球蛋白如何通过暂时采用珠状形状来保护轴突免受轻度机械应激,这种形状有助于限制破坏性钙波的传播。
