作者要感谢哈特维格·维博尔德的出色技术援助，以及汉堡-埃彭多夫大学医学中心的UKE显微镜成像设施（Umif）提供显微镜和支持。这项研究由DZHK（德国心血管研究中心）[FKZ 81Z4710141]资助。

所有涉及动物的程序都得到汉堡州动物护理和使用委员会（ORG870，959）和北莱茵-威斯特法伦州自然、环境和消费者保护局（LANUV，07/11）的批准，并符合国家卫生研究院的实验室动物护理和使用指南（2011年）。研究使用男性和女性（10-24周）C57BL/6小鼠（库存号000664，杰克逊实验室）和小鼠同源性（db/db）或异质性（db/het：控制）为糖尿病自发突变（Leprdb：Bks.Cg-Dock7m+/+ 勒普db/J，股?...

对VA发病前交感神经系统神经元和胶质细胞的细胞和分子过程的理解是高度关注的，因为心脏骤停仍然是全世界最常见的死因。因此，在当前的手稿中，我们提供了一系列基本的方法来识别该网络中的穆林 SG - 喃喃元素 ， 并随后对 RNA、蛋白质和细胞水平进行分析。
Murine SG的一个挑战是它的大小和有限的细胞数量39。因此，不同的动物模型?...

心脏自主神经系统是一种受严格控制的交感、寄生和感官成分的平衡，使心脏能够适应环境变化，并具有适当的生理反应1，2。这种平衡的干扰，例如，同情活动的增加，已被确定为发病和维持心室心律失常（VA）3，4的关键驱动因素。因此，自主调制，通过药理学减少与β阻滞剂的交感活性，一直是治疗VA患者几十年的基石5，6。但是，尽管药理学和导管为基础的干预，相关数量的患者仍然患有复发性VA7。
对心脏的交感输入主要通过交感链的双星形结构——神经元细胞体进行中介，这种结构通过无数的胸内神经从脑干传递信息到心脏8、9、10。受伤后从SG发芽的神经与VA和心脏骤死11，12有关，强调SG作为自主调制的目标13，14。通过局部麻醉剂的皮下注射或通过视频辅助胸腔镜检查15、16部分切除SG，可以暂时减少对心脏的交感输入。心脏交感衰竭为治疗难治VA的患者提供了一个选择，结果有希望的结果14，16，17。我们从这些患者的外植SG中了解到，神经元和神经化学改造、神经炎症和胶质活化是同情性重塑的标志，可能有助于或加重自主功能障碍18，19。尽管如此，这些神经元中潜在的细胞和分子过程至今仍然模糊不清，例如，神经元分化成胆碱表型20，21的作用。实验研究提出了治疗VA的新方法，例如，通过光遗传学22减少交感神经活动，但SG的深度表征仍然缺乏许多心脏病理与VA齐头并进。模仿这些病理学的小鼠模型可以研究神经元重塑，这可能先于心律失常12，23的发生。这些可以通过进一步的形态和功能分析来完成，以实现心脏和神经系统的自主特征。在本协议中，我们提供了一系列基本的方法，允许解剖和描述 Murine SG，以增进对 VA 的理解。

location, dissection, and analysis of the murine stellate ganglion

自主神经系统是心脏电生理学的一大驱动力。特别是其同情分支的作用是心室心律失常（VA）病理生理学中正在进行的研究。交感链的双子星形结构（SG）   中的神经元   是交感基础设施的重要组成部分。SG 是治疗难治 VA 患者通过心脏交感衰减而公认的治疗目标。虽然在SG的神经元重塑和胶质激活已经描述了VA患者，潜在的潜在的细胞和分子过程，潜在的心律失常开始之前，只是不够了解，应该阐明，以改善自主调节。小鼠模型允许我们研究交感神经元改造，但对缺乏经验的研究者来说，识别穆林SG是具有挑战性的。因此，许多常见的心脏病缺乏对穆林SG的深入细胞和分子生物学研究。在这里，我们描述了解剖和研究成年小鼠SG的基本剧目，用于RNA水平分析（基因表达分析的RNA分离，原位杂交）、蛋白质水平（免疫荧光全安装染色）和细胞水平（基本形态、细胞大小测量）。我们提出潜在的解决方案，以克服制备技术中的挑战，以及如何通过淬火自流来改善染色。这允许通过既定标记对神经元和胶质细胞进行可视化，以确定细胞组成和重塑过程。这里介绍的方法允许SG的特征获得关于容易发生VA的小鼠自主功能障碍的进一步信息，并可以辅之以额外的技术来研究心脏自主神经系统的神经元和胶质成分。
