改变神经元功能的分子靶点或化合物的发现可以带来改善与年龄相关的神经退行性疾病的治疗进展。目前,缺乏体内筛选技术来发现影响年龄依赖性神经元生理学的化合物。在这里,我们提出了一种高通量、基于微流体的测定方法,用于自动操作和片上监测和分析完整秀丽隐杆线虫在不同生命阶段的刺激诱发的钙反应。首先,我们成功应用我们的技术来量化衰老以及与年龄相关的遗传和化学因素对 ASH 感觉神经元钙瞬变的影响。然后,我们对 FDA 批准的 107 种化合物库进行了大规模筛选,以确定能够防止 ASH 年龄依赖性功能恶化的化合物。我们的检测方法的强大性能使其成为未来基于体内功能成像的高通量应用的宝贵工具。
Discovery of molecular targets or compounds that alter neuronal function can lead to therapeutic advances that ameliorate age-related neurodegenerative pathologies. Currently, there is a lack of in vivo screening technologies for the discovery of compounds that affect the age-dependent neuronal physiology. Here, we present a high-throughput, microfluidic-based assay for automated manipulation and on-chip monitoring and analysis of stimulus-evoked calcium responses of intact C. elegans at various life stages. First, we successfully applied our technology to quantify the effects of aging and age-related genetic and chemical factors in the calcium transients of the ASH sensory neuron. We then performed a large-scale screen of a library of 107 FDA-approved compounds to identify hits that prevented the age-dependent functional deterioration of ASH. The robust performance of our assay makes it a valuable tool for future high-throughput applications based on in vivo functional imaging.
