线粒体是生物体最为重要的细胞器之一,对维持人体正常生理功能具有重要的作用,线粒体功能紊乱与多种疾病的发生和发展相关。细胞培养或体外线粒体分离技术常用于评估外源性物质对线粒体的作用,但是这些方法不能准确反映体内各种因素的影响。活体内线粒体功能评估有助于更为完整、全面地了解其生物学功能,遗憾的是,到目前为止,仍没有一种评估方法被临床广泛认可,但是磁共振波谱(magnetic resonance spectroscopy, MRS)、PET、呼吸试验、血尿代谢组学评估以及替代细胞群[如外周血单核细胞(peripheral blood mononuclear cell, PBMC)]等评估方式的出现对科研及临床工作都具有一定的指导意义。本文就活体内线粒体功能评估的方法作一综述。

摘要: 线粒体在维持人体正常生理功能中具有重要的作用,线粒体功能紊乱与多种疾病的发生和发展相关。活体内线粒体功能评估有助于更为完整、全面地了解其生物学功能,该文就活体内线粒体功能评估的方法作一综述。Abstract: Mitochondria play a major role in normal metabolism of the body. Therefore, mitochondrial dysfunction inevitably participates in or even determines the onset and progression of many diseases. Methods for in vivo assessment of mitochondrial function would help understand the biological function of mitochondria. This review focuses on the methods to assess mitochondrial function in vivo.
