隔膜是“呼吸泵”;肌肉产生的压力,让通风。膈肌起着至关重要的作用,因此受到持续的机械负荷。它的一个特点是能够产生不同的机械和生化反应,这取决于施加到它的机械力的方向。收缩力来自于它的收缩组件被传输到其他结构组件的肌肉纤维和周围的结缔组织。横膈膜的各向异性机械特性被转化为生物化学信号,该生物化学信号通过似乎是该肌肉所特有的机制而具有定向机械敏感性。在这里,我们回顾了目前的知识状态的生化途径调节的机械信号,强调其各向异性的行为在正常的隔膜和分析它们是如何影响肌营养不良症。
The diaphragm is the “respiratory pump;” the muscle that generates pressure to allow ventilation. Diaphragm muscles play a vital function and thus are subjected to continuous mechanical loading. One of its peculiarities is the ability to generate distinct mechanical and biochemical responses depending on the direction through which the mechanical forces applied to it. Contractile forces originated from its contractile components are transmitted to other structural components of its muscle fibers and the surrounding connective tissue. The anisotropic mechanical properties of the diaphragm are translated into biochemical signals that are directionally mechanosensitive by mechanisms that appear to be unique to this muscle. Here, we reviewed the current state of knowledge on the biochemical pathways regulated by mechanical signals emphasizing their anisotropic behavior in the normal diaphragm and analyzed how they are affected in muscular dystrophies.
