机械性痛觉过敏是一种临床相关的疼痛致敏形式,其发展机制在很大程度上是未知的。TRPA1是一种瞬时受体电位离子通道,是一种刺激性化学物质的传感器,可能在急性有毒机械感觉和冷热感觉中起作用。我们已经开发了一种特异性的小分子TRPA1抑制剂(AP18),可以在体内减少肉桂醛诱导的伤害感受。有趣的是,AP18能够逆转cfa诱导的小鼠机械性痛觉过敏。尽管trpa1缺陷小鼠会出现正常的cfa诱导的过度代谢,但AP18在敲除小鼠中无效,这与靶向机制一致。因此,TRPA1在伤害感受的致敏中起作用,而TRPA1缺陷小鼠的代偿掩盖了这一要求。
Mechanical hyperalgesia is a clinically-relevant form of pain sensitization that develops through largely unknown mechanisms. TRPA1, a Transient Receptor Potential ion channel, is a sensor of pungent chemicals that may play a role in acute noxious mechanosensation and cold thermosensation. We have developed a specific small molecule TRPA1 inhibitor (AP18) that can reduce cinnameldehyde-induced nociception in vivo. Interestingly, AP18 is capable of reversing CFA-induced mechanical hyperalgesia in mice. Although TRPA1-deficient mice develop normal CFA-induced hyperalgeisa, AP18 is ineffective in the knockout mice, consistent with an on-target mechanism. Therefore, TRPA1 plays a role in sensitization of nociception, and that compensation in TRPA1-deficient mice masks this requirement.
