使用病毒来研究神经回路是一个相对较高的吞吐量，连接神经元的分析方法。但是，生成，VSV和RABV病毒颗粒是不平凡的。虽然提供了上面列出的用于从cDNA拯救病毒的协议，它仍然是一个低概率事件。水平的每一个的N，P和L的质粒中需要被精确地调整，需要做的工作，以确保病毒救援和许多试验和复制。将一个完整的VSV基因组RNA的核苷酸颗粒的形成是一个低概率事件，因此可能需要多次尝试。这?...

viral tracing of genetically defined neural circuitry

古典方法研究神经回路是相当低的吞吐量。病毒跨突触，特别是伪狂犬（PRV）和狂犬病毒（RABV），，最近水泡性口炎病毒（VSV），学习电路，正变得越来越流行。这些高通量的方法使用顺行或逆行方向的神经元之间传递的病毒。 近日，RABV突触逆行追踪。 （ 图1A）。在这种方法中，糖蛋白（G）的基因被删除从病毒基因组中，仅在目标神经元和补给。感染特异性达到代的嵌合G，ASLV-阿糖蛋白和胞质域的RABV-G（A / RG）的胞外结构域组成，正常RABV-G 1。特别是感染这种嵌合G TVA受体1的表达。该基因编码TVA已经Delivered通过各种方法2-8。 RABV-G感染的TVA表达神经元，RABV可以传输到其他突触连接的神经元在逆行方向的性质，这是交付的TVA受体的G。这种技术标签相对大量的输入（5-10％）2到一个定义的细胞类型，提供了一个采样到一个定义的起动器的细胞类型中的所有的输入。 我们最近修改了这个技术的使用VSV作为一个跨突触示踪9。 VSV有几个好处，包括快速的基因表达。在这里，我们详细介绍了新的病毒跟踪系统，使用VSV有用的探测微型电路与更高的分辨率。在原来的出版策略，由威克沙姆等。4和贝尔等人。9许可证标记神经元的任何项目上最初感染TVA-表达细胞，在这里VSV被设计仅传输到电视A-细胞（ 图1B）。该病毒是第一个假RABV-G允许感染下游TVA表达神经元的神经元。这个第一群细胞感染后，病毒发布只能感染TVA-表达细胞。由于跨突触的病毒传播是有限的TVA-细胞的自定义类型的细胞连接的情况下，存在可以被探索和高分辨率。这些实验是在图2中所示的实验流程图。在这里，我们展示一个模型电路，在小鼠视网膜的方向选择性。我们考察爆无长突细胞（SACS）的连通性视网膜神经节细胞（RGC）。
