肌纤维中的自发波
Spontaneous waves in muscle fibres
摘要：
机械振荡对于许多细胞过程都很重要，例如纤毛和鞭毛的跳动或毛细胞对声音的感觉。这些动力学状态起源于分子马达的自发振荡。在非生理条件下的肌纤维中观察到了这种振荡的一个特别明显的例子。在这种情况下，电机振荡导致沿着纤维的收缩波。通过对肌纤维动力学的宏观分析，我们发现自发波涉及非流体动力学模式。肌节动力学的一个简单的微观模型突出了电机动力学的机械方面，并符合实验观察。
英文摘要：
Mechanical oscillations are important for many cellular processes, e.g. the beating of cilia and flagella or the sensation of sound by hair cells. These dynamic states originate from spontaneous oscillations of molecular motors. A particularly clear example of such oscillations has been observed in muscle fibers under non-physiological conditions. In that case, motor oscillations lead to contraction waves along the fiber. By a macroscopic analysis of muscle fiber dynamics we find that the spontaneous waves involve non-hydrodynamic modes. A simple microscopic model of sarcomere dynamics highlights mechanical aspects of the motor dynamics and fits with the experimental observations.
