项目摘要
PROJECT SUMMARY
Although great efforts have been dedicated to characterizing neuronal cell types in the brain, systematic
studies on the brain-spinal cord connectome and associated spinal neuronal types are lacking. In this project, a
team of seven laboratories proposes to use a highly innovative and multidisciplinary approach to systematically
characterize neuronal types in the spinal cord based on their anatomy, connectivity, neuronal morphologies,
molecular identities, and electrophysiological properties. In Aim 1, we will use a newly developed AAV
anterograde transsynaptic tagging method to label spinal cord neurons that receive descending inputs from
different brain regions, and use a retrograde viral tracer, AAVretro, to label spinal neurons that project to
defined brain regions. These tagged neurons will be imaged in the intact whole spinal cord with a newly
developed fast 3D light sheet microscopy technique, and targeted for recording in slice preparations. The
axonal collateral patterns, dendritic morphologies, and electrophysiological properties will be compared
between different input/output-defined spinal neuron groups. In Aim 2, the gene expression patterns of the
tagged neurons will be determined in situ by sequential bar-coded FISH (seqFISH), with candidate marker
genes obtained from online resources, or from single-cell sorting and RNA sequencing (Dropseq). In Aim 3, all
collected data on connectivity, anatomical cell type distribution map, neuronal morphologies, molecular
identities, and electrophysiological properties will be used for classifying spinal neuron types connected with
brain, and an open-source data portal will be established which will allow users to search, view, and analyze
the multi-modal and integrative cell-type specific data. Together, we aim to construct a comprehensive cell-
type atlas of the mouse brain-spinal cord connectome.
项目摘要
尽管已经做出了很大的努力来表征脑中的神经元细胞类型,但系统性的神经元细胞类型的研究仍然是一个难题。
缺乏对脑-脊髓连接体和相关脊髓神经元类型的研究。在这个项目中,A
由七个实验室组成的团队建议采用高度创新和多学科的方法,
基于它们的解剖学、连接性、神经元形态学表征脊髓中的神经元类型,
分子身份和电生理特性。在目标1中,我们将使用新开发的AAV
顺行跨突触标记方法来标记脊髓神经元,所述脊髓神经元从
不同的大脑区域,并使用逆行病毒示踪剂AAVretro标记脊髓神经元,
大脑的特定区域。这些标记的神经元将在完整的整个脊髓中成像,
开发了快速3D光片显微镜技术,并有针对性地记录在切片准备。的
将比较轴突侧支模式、树突形态和电生理特性
不同的输入/输出定义的脊髓神经元组之间。在目标2中,基因表达模式,
标记的神经元将通过顺序条形码FISH(seqFISH)原位确定,候选标记物
从在线资源或从单细胞分选和RNA测序(Dropseq)获得的基因。在目标3中,
收集的关于连接性、解剖细胞类型分布图、神经元形态、分子生物学和神经元结构的数据。
身份,和电生理特性将用于分类脊髓神经元类型与
brain,并将建立一个开源数据门户,允许用户搜索、查看和分析
多模态和综合的细胞类型特定数据。我们要一起建立一个综合小组-
小鼠脑-脊髓连接体的类型图谱。
