细胞尺度的机械振荡

Mechanical oscillations at the cellular scale

Frank Julicher

摘要:

涉及力产生和运动的主动现象在活细胞中的许多现象中起关键作用,例如细胞运动、肌肉收缩以及物质和细胞器的主动运输。在这里,我们讨论的机械振荡所产生的积极系统在细胞。例如肌肉的振荡状态、轴丝纤毛和鞭毛的周期性搏动以及听毛细胞的自发振荡,这些在听力中微弱声音的主动放大中发挥作用。作为蛋白质振荡产生的原型系统,我们讨论了一个一般的机制,许多耦合的活性元素,如电机分子可以产生振荡。

英文摘要:

Active phenomena which involve force generation and motion play a key role in a number of phenomena in living cells such as cell motility, muscle contraction and the active transport of material and organelles. Here we discuss mechanical oscillations generated by active systems in cells. Examples are oscillatory regimes in muscles, the periodic beating of axonemal cilia and flagella and spontaneous oscillations of auditory hair cells which play a role in active amplification of weak sounds in hearing. As a prototype system for oscillation generation by proteins, we discuss a general mechanism by which many coupled active elements such as motor molecules can generate oscillations.
