项目总结
肺是一个神经丰富的器官。强有力的证据,包括我们最近的发现,表明
神经元控制在肺对环境的基本反应中发挥核心作用,包括免疫活动,如
以及影响空气传导性和肺血液的呼吸道和血管平滑肌张力

对支配肺的神经元的解剖学和分子特征尚不清楚,也知之甚少。
在这里,我们建议使用尖端的基于病毒的电路跟踪,单细胞转录和单倍体ES细胞-

英文摘要
PROJECT SUMMARY
The lung is a richly innervated organ. Strong evidence, including recent findings from us, demonstrates that
neuronal control plays central roles in basic lung response to the environment, including immune activity, as
well as airway and vascular smooth muscle tone which impacts air conductance and pulmonary blood
pressure, respectively. However, the full extent of how the nervous system affects lung function remains
unclear, and little is known of the anatomical and molecular features of the neurons that innervate the lung.
Here, we propose to use cutting-edge viral-based circuit tracing, single cell transcriptomic and haploid ES cell-
based genome editing technologies to: 1) label lung-innervating neurons; 2) determine their localization and
projection pattern; 3) generate knockin mouse lines that will lay the foundation for neuromodulation of lung
function. Findings generated in mice will be tested in human biopsy samples to delineate conserved versus
species-specific mechanisms. With the development of wireless, implantable devices, neuromodulatory
therapy is on the horizon. Findings from this study will lay the necessary foundation for precise manipulation of
organ function through the nervous system, and thus closely comply with the mission of the SPARC program.
