基于整体生物体的筛选有望发现生物活性化合物。然而,由于定位活体动物的困难和神经元计数的个体差异,高内涵成像具有挑战性。在这里,我们提出了一个协议,使用基于图像的小分子屏幕来识别斑马鱼多巴胺能神经元的神经保护化合物。我们描述了饲养幼虫、琼脂糖包埋和诱导神经变性的治疗的步骤。然后,我们详细介绍实时共焦成像、图像处理和数据分析的程序。有关该协议的使用和执行的完整详细信息,请参阅 Kim 等人。 (2021)。基于体内成像的神经退行性疾病整体生物体筛查方案 将幼虫背侧埋入和定位在 96 孔板中的分步指南 斑马鱼幼虫间脑治疗前后的实时共聚焦成像 使用开源程序量化多巴胺神经元损失的自动化流程 出版商注:进行任何实验方案都需要遵守当地实验室安全和道德机构指南。基于整体生物体的筛选有望发现生物活性化合物。然而,由于定位活体动物的困难和神经元计数的个体差异,高内涵成像具有挑战性。在这里,我们提出了一个协议,使用基于图像的小分子屏幕来识别斑马鱼多巴胺能神经元的神经保护化合物。我们描述了饲养幼虫、琼脂糖包埋和诱导神经变性的治疗的步骤。然后,我们详细介绍实时共焦成像、图像处理和数据分析的程序。
Whole-organism-based screen holds promise for discovering biologically active compounds. However, high-content imaging is challenging due to the difficulty of positioning live animals and individual variability of neuron counts. Here, we present a protocol to identify neuroprotective compounds for dopaminergic neurons in zebrafish using an image-based small-molecule screen. We describe steps for raising larvae, agarose embedding, and treatment to induce neurodegeneration. We then detail procedures for live confocal imaging, image processing, and data analysis. For complete details on the use and execution of this protocol, please refer to Kim et al. (2021).
