气态神经递质

气态神经递质（英语：Gasotransmitter）是一类神经传导物质。这些分子与其他生物活性内源性气体讯号分子的差异在于需要满足不同的表征标准。目前，只有一氧化氮、一氧化碳和硫化氢被接受为气态神经递质。[1] 根据体外模型 (英语：In Vitro Model)，气体传导物质与其他气体讯号分子一样，可能与气体感受器结合并触发细胞中的讯号传导。[1]

气态神经递质这个名称并不意味著气态物理状态，例如无限小的气泡；物理状态是溶解在复杂的体液和细胞质中。[2]这些特殊气体在其生产和功能上具有许多共同特征，但以不同于经典讯号分子的独特方式执行其任务。

准则

编辑

"气态神经递质"的术语和表征准则于2002年首次引入。[3]对于一种被归类为气态神经递质的气体分子，应符合以下所有准则。[4][3]

  1. 它是一种小分子气体；
  2. 它可自由渗透膜。因此，其作用不依赖同源膜受体。它可以具有内分泌、旁分泌和自分泌作用。例如，在内分泌作用模式下，气态神经递质可以进入血流；被清道夫携带到远端目标并释放在那里，调节远端目标细胞的功能；
  3. 它是内源性酵素产生的，其产生受到调节；
  4. 它在生理相关浓度下具有明确且特定的功能。因此，控制这种气体的内源水平会引起特定的生理变化。
  5. 这种内源性气体的功能可以透过其外源性应用的对应物来模仿；
  6. 其细胞效应可能由第二信使介导，也可能不由第二信使介导，但应具有特定的细胞和分子标靶。

概述

编辑

讽刺的是，目前的气体递质“三位一体”，即一氧化氮、一氧化碳和硫化氢，在历史上一直被当作无用的有毒气体而丢弃。这些分子是剂量依赖性毒物兴奋效应的典型例子，低剂量是有益的，而缺乏或过量剂量则是有毒的。这些内源性分子的有益作用激发了每种气体的重大药物开发工作。

这三种气体具有许多相似的特征，并参与共享的信号传导途径，尽管它们的作用可以是协同的，也可以作为拮抗剂。[5][6]一氧化氮和硫化氢与许多分子标靶高度反应，而一氧化碳相对稳定且代谢惰性，主要限于与哺乳动物体内的亚铁离子复合物相互作用。[7] 然而，不同系统发育界的生物功能范围有所不同，一氧化碳与镍或钼一氧化碳脱氢酶的重要交互作用就是例证。[8]

气态神经递质正在接受以下学科的研究：生物传感[9][10]、免疫学[11][12]、神经科学[13][14]、胃肠病学[15][16][17]、和许多其他领域包括药物开发措施。[18][19][20]虽然生物医学研究受到了最多的关注，但整个生物界都在研究气态神经递质。[21][22][23][24]

已经开发了许多分析工具来协助气体递质的研究。[25]
