项目摘要

DESCRIPTION (provided by applicant): The mammalian brain, including the human brain, contains dozens of peptides that act as neurotransmitters between cells but whose function and modes of action are relatively unknown. This is particularly true in the basal ganglia in which the expression of peptides and of peptide receptors varies from cell to cell and nucleus to nucleus. The basal ganglia play a central role in controlling motor action selection - i.e. deciding what we do - and are at the heart of human disorders such as Parkinson's, Huntington's and drug addiction. We propose to study the function of peptides in the basal ganglia in order to understand how they signal and control the circuitry of this structure. We will make use of new technology developed in the laboratory that allows us to precisely release peptides in mammalian brain tissue using pulses of light. This will be used to analyze peptide function in tissue in which specific classes of neurons are marked or placed under optogenetic control. The proposed work will shed light on the basic biology of this conserved signaling system and will inform how its perturbation contributes to disease.

描述（由申请人提供）：包括人脑在内的哺乳动物大脑包含数十种肽，它们在细胞之间充当神经递质，但其功能和作用方式相对尚不清楚。在基底神经节中尤其如此肽和肽受体的表达因细胞到细胞和细胞核而异。基底神经节在控制运动动作选择方面起着核心作用 - 即决定我们什么做 - 并且是帕金森氏症，亨廷顿和吸毒等人类疾病的核心。我们建议研究肽在基底神经节中的功能，以了解它们如何发出信号和控制该结构的电路。我们将利用实验室开发的新技术，使我们能够使用光脉冲在哺乳动物脑组织中精确释放肽。这将用于分析组织中特定类别的神经元的肽功能，以将特定类别的神经元标记或放置在光遗传内。拟议的工作将阐明该保守信号系统的基本生物学，并将告知其扰动如何对疾病有效。
