三磷酸腺苷(ATP)是跨单细胞和多细胞物种的代谢和信号传导的通用介质。ATP的动力学和细胞内外发生的生理学之间存在着基本的相互依赖关系。表征和理解ATP动力学为从神经传递到免疫细胞的趋化性的过程提供了有价值的机制见解。因此,我们需要的方法来询问ATP动力学的时间和空间成分从亚细胞到活体标本的有机体水平。在过去的几十年中,已经开发了许多对ATP具有特异性的分子探针。这些探针已与成像方法,特别是光学显微镜,使定性和定量检测这一关键分子相结合。在本文中,我们调查了当前可用于可视化活细胞中ATP的技术示例,并确定需要新工具和方法来扩展我们能力的领域。
Adenosine triphosphate (ATP) is a universal mediator of metabolism and signaling across unicellular and multicellular species. There is a fundamental interdependence between the dynamics of ATP and the physiology that occurs inside and outside the cell. Characterizing and understanding ATP dynamics provides valuable mechanistic insight into processes that range from neurotransmission to the chemotaxis of immune cells. Therefore, we require the methodology to interrogate both temporal and spatial components of ATP dynamics from the subcellular to organismal levels in live specimens. Over the last several decades, a number of molecular probes that are specific for ATP have been developed. These probes have been combined with imaging approaches, particularly optical microscopy, to enable qualitative and quantitative detection of this critical molecule. In this review, we survey current examples of technologies that are available to visualize ATP in living cells and identify areas where new tools and approaches are needed to expand our capabilities.
