心磷脂(Cardiolipin, CL)是线粒体独有的磷脂,主要定位于线粒体内膜内,在线粒体结构和功能中起重要作用。异常的CL含量、结构和定位都与线粒体活性受损有关,并在癌症、神经系统、心血管和代谢疾病的病理生理学中观察到。CL物种的检测、定量和定位是研究线粒体功能障碍和几种人类疾病的病理生理机制的有价值的工具。使用液相色谱法测量CL,通常结合质谱法、质谱成像、散弹枪脂质组学、离子迁移率光谱法、荧光法和放射性标记。本文综述了现有的氯离子分析方法,特别是现代质谱法,并评价了它们的优点和局限性。我们提供指导,旨在选择最合适的技术,或技术组合,当分析在不同的模型系统,并强调临床背景下,测量CL是相关的。
Cardiolipin (CL) is a mitochondria-exclusive phospholipid, primarily localised within the inner mitochondrial membrane, that plays an essential role in mitochondrial architecture and function. Aberrant CL content, structure, and localisation have all been linked to impaired mitochondrial activity and are observed in the pathophysiology of cancer and neurological, cardiovascular, and metabolic disorders. The detection, quantification, and localisation of CL species is a valuable tool to investigate mitochondrial dysfunction and the pathophysiological mechanisms underpinning several human disorders. CL is measured using liquid chromatography, usually combined with mass spectrometry, mass spectrometry imaging, shotgun lipidomics, ion mobility spectrometry, fluorometry, and radiolabelling. This review summarises available methods to analyse CL, with a particular focus on modern mass spectrometry, and evaluates their advantages and limitations. We provide guidance aimed at selecting the most appropriate technique, or combination of techniques, when analysing CL in different model systems, and highlight the clinical contexts in which measuring CL is relevant.
