摘要:

机械性痛觉过敏是痛觉过敏的一种,表现为机械刺激引起的周围正常组织感觉敏感性增强,其传导机制十分复杂,目前尚未能完全阐明。近年来,有研究发现在真核生物中,多种力敏感离子通道(mechanosensitive ion channel, MSC)在机械痛觉过敏的传导中发挥着重要作用,其中主要包括瞬时受体电位(transient receptor potential, TRP)家族及压电(Piezo)离子通道家族等。位于外周神经末梢的MSC能被机械性刺激激活,从而参与疼痛信号的转导过程。而抑制MSC的开放,将有助于阻止这一信号的转导。由此,文章对不同类型MSC参与机械性痛觉过敏的机制做进一步的总结以及深入理解MSC参与机械性痛觉过敏的过程,从而为机械性痛觉过敏的治疗提供新的药物靶点。

Abstract:

Mechanical hyperalgesia is a type of hyperalgesia, which is manifested by the pain of normal tissue sensitivity caused by mechanical stimulation. The conduction mechanism is complicated and cannot be fully elucidated at present. Recent studies indicated the important role of multiple mechanosensitive ion channel(MSC) in the mechanotransduction of mechanical hyperalgesia in eukaryotes, including transient receptor potential (TRP) channels and Piezo channel. MSC in nerve ending can be activated by mechanical stimulation, which involved in the pain signals transduction. Inhibition of the MSC results in the blockade of the signals. Therefore, the review was to further summarize the mechanisms of different types of MSC involved in mechanical hyperalgesia and to further understand of the process of MSC involved in mechanical hyperalgesia, which then provide new drug targets for the therapy of mechanical hyperalgesia.
