This chapter provides a comprehensive overview of methodologies currently employed to study ion channels, particularly transient receptor potential melastatin 3 (TRPM3) in the context of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). Sample preparation involves the collection of whole blood, separation of peripheral blood mononuclear cells (PBMCs) via density gradient centrifugation, and isolation of natural killer (NK) cells. Protein expression analysis utilizes flow cytometry, liquid chromatography-mass spectrometry (LC-MS), western blotting, and immunofluorescence techniques. Functional analysis focuses on calcium imaging and electrophysiology techniques to investigate ion channel responses to pharmacological stimuli. The authors highlight that some experimental protocols included within this chapter require specialized training and equipment. In order to replicate these protocols extended training is advised, specifically when attempting electrophysiology experimentation. The use of advanced techniques for detailed analysis provides insights into ion channel function and potential implications in the pathomechanism of ME/CFS offering avenues for further research and therapeutic exploration.
本章全面概述了目前用于研究离子通道的方法,特别是在肌痛性脑脊髓炎/慢性疲劳综合征(ME/CFS)背景下的瞬时受体电位褪黑素3(TRPM3)。样本制备包括采集全血、通过密度梯度离心分离外周血单核细胞(PBMC)以及分离自然杀伤(NK)细胞。蛋白质表达分析利用流式细胞术、液相色谱-质谱联用(LC-MS)、蛋白质印迹法和免疫荧光技术。功能分析侧重于钙成像和电生理技术,以研究离子通道对药理刺激的反应。作者强调,本章中包含的一些实验方案需要专门的培训和设备。为了重复这些方案,建议进行扩展培训,特别是在尝试电生理实验时。使用先进技术进行详细分析有助于深入了解离子通道功能以及在ME/CFS发病机制中的潜在影响,为进一步研究和治疗探索提供了途径。
