项目摘要
Pain is a widespread and persistent public health problem with myriad socio-economic
ramifications, including addiction and opiate use disorders. Many therapeutics used for pain
management today have their origins in plants, from aspirin to opiates. Still, most plant derived
compounds have not been studied extensively for their bioactivity, including many that are
synthesized by medicinal plants. This application is submitted to PA-18-591 in response to
NOT-TR-20-008, a call for studies to characterize understudied proteins in the druggable human
genome with the potential to serve as new targets for the treatment of pain. We propose to
establish a rapid research pipeline for linking plant-derived compounds to nociception (pain) and
to GPCRs and ion channels in the druggable human genome. As more than 80% of these
membrane proteins are conserved in C. elegans and this model organism is a proven platform
for phenotypic screens, we propose screens for compounds and genes affecting nociception as
well as to identify novel ligand-receptor pairs using C. elegans nematodes. We will first link
plant-derived compounds to modulation of thermal nociceptors and then to determine which of
the understudied, but conserved GPCRs and ion channels are involved in nociception in the
presence or absence of entry point compounds (Aim 1) and next exploit the fact that C. elegans
chemosensory neurons express multiple GPCRs and that activation of these receptors causes
either attraction or repulsion behaviors (Aim 2). This innovative research project has the
potential to determine the function of the specified genes in nociception and to reveal novel
ligand-receptor pairs that could serve as new entry points for improved or alternative pain
treatments.
疼痛是一个广泛而持久的公共卫生问题,
后果,包括成瘾和阿片类药物使用障碍。许多用于疼痛的疗法
从阿司匹林到鸦片,今天的管理都起源于植物。然而,大多数植物来源的
化合物的生物活性尚未被广泛研究,包括许多
由药用植物合成。本申请提交给PA-18-591,以回应
NOT-TR-20-008,呼吁研究表征可药用人类中未充分研究的蛋白质
基因组有可能成为治疗疼痛的新靶点。我们建议
建立一个快速研究管道,将植物衍生化合物与伤害感受(疼痛)联系起来,
基因组聚合酶链式反应和离子通道。因为超过80%的
膜蛋白在C.这个模式生物是一个被证明的平台
对于表型筛选,我们建议筛选影响伤害感受的化合物和基因,
并利用C.线虫我们将首先链接
植物衍生的化合物来调节热伤害感受器,然后确定哪种
研究不足,但保守的GPCR和离子通道参与伤害性感受,
存在或不存在的切入点化合物(目标1),并接下来利用的事实,C。elegans
化学感受神经元表达多种GPCR,这些受体的激活导致
吸引或排斥行为(目标2)。这个创新的研究项目,
确定特定基因在伤害感受中的功能并揭示新的
配体-受体对可以作为改善或替代疼痛的新切入点
治疗。
