Stereotaxic Adeno-associated Virus Injection and Cannula Implantation in the Dorsal Raphe Nucleus of Mice

[Abstract]  Optogenetic methods are now widespread in neuroscience research. Here we present a detailed surgical procedure to inject adeno-associated viruses and implant optic fiber cannulas in the dorsal raphe nucleus (DRN) of living mice. Combined with transgenic mouse lines, this protocol allows specific targeting of serotonin-producing neurons in the brain. It includes fixing a mouse in a stereotaxic frame, performing a craniotomy, virus injection and fiber implantation. Animals can be later used in behavioral experiments, combined with optogenetic manipulations (Dugué et al., 2014; Correia et al., 2017) or monitoring of neuronal activity (Matias et al., 2017).

The described procedure is a fundamental step in both optogenetic and fiber photometry experiments ...
[摘要]  光神学研究现在广泛存在。在这里,我们提供一个详细的外科手术,以注射腺相关病毒和植入光纤插管在活的小鼠背侧核心(DRN)。结合转基因小鼠系,该方案允许在脑中特异性靶向产生5-羟色胺的神经元。它包括将鼠标固定在立体定位框架中,执行开颅手术,病毒注射和纤维植入。动物可以随后用于行为实验,结合光遗传操作(Dugué等,2014; Correia等,2017)或监测神经元活动(Matias等,2017)。
  所描述的程序是深部脑区域的光生和光纤测光实验中的基本步骤。它针对DRN中的血清素神经元进行了优化,但可以应用于任何其他细胞类型和脑区域。当使用表达功能相关水平的光遗传工具或报告物系的转基因小鼠品系时,可以跳过病毒注射步骤,并将该方案降低到插管植入程序。
【背景】随着光遗传学方法的出现,使用光纤和遗传编码的探针来操纵或监测大脑活动已迅速扩大。光致发光工具对于研究神经调节系统特别有用,因为它们通常以位于深部脑区域的神经元簇为特征,对多个脑区域进行长期和广泛的预测。先前已经针对脑中的不同区域描述了病毒注射和纤维插管植入(例如,腹侧被盖区域[Tsai等人,2009],基因座(Carter等,2010))。
  鉴于其深部解剖学位置在导管和上矢状窦下方,针对背侧核心核(DRN,血清素投影到前脑的主要来源)可能是复杂的。使用标准的外科手术可能导致大量出血和低成功率,导致样本量较小(Ranade和Mainen ...

[Abstract]  We here provide a detailed protocol for the isolation and culture of primary mouse sensory neurons. The cell bodies of sensory afferent pseudounipolar neurons are located in dorsal root ganglia (DRGs) along the vertebral column. Dissected mouse DRGs can be dissociated into single cells by enzymatic digestion to obtain primary cultures of mouse sensory neurons as performed in the studies reported by Khaminets et al. (2015). [摘要]  我们在这里提供了详细的协议,用于隔离和培养的主要小鼠感觉神经元。 感觉传入假性极化神经元的细胞体位于沿着脊柱的背根神经节(DRG)中。 解离的小鼠DRG可以通过酶消化解离成单个细胞,以获得小鼠感觉神经元的原代培养物,如Khaminets等人(2015)报道的研究中所进行的。
