Skeletal muscle is an essential organ for the motor functions and its defects are associated with functional impairments of other organs including brain. Muscle contraction is the fundamental skeletal muscle function and is strictly controlled by motor neuron, which requires neuromuscular junction (NMJ), a chemical synapse between motor nerve terminal and myotube (myofiber). Defects in NMJ cause various functional abnormalities of skeletal muscle including muscle weakness. This review presents an overview of the current understanding of signaling in NMJ formation and maintenance in skeletal muscle and the development of NMJ-targeted therapeutics.
骨骼肌是运动功能的重要器官,其缺陷与包括大脑在内的其他器官的功能障碍有关。肌肉收缩是骨骼肌的基本功能,受到运动神经元的严格控制,这需要神经肌肉接头(NMJ),即运动神经末梢与肌管(肌纤维)之间的化学突触。神经肌肉接头的缺陷会导致骨骼肌出现各种功能异常,包括肌肉无力。本文综述了目前对骨骼肌中神经肌肉接头形成和维持过程中信号传导的理解以及针对神经肌肉接头的治疗方法的进展。
