摘要

无脊椎动物的物种数量是脊椎动物的 20 倍,对无脊椎动物进行光学显微鉴定对整个神经科学具有基础性和应用性意义。在这里,通过光学清除无脊椎动物来识别其形态和神经结构的方法至今仍未实现。在此,我们报告了对任何年龄和厚度(最长 2 厘米)、具有复杂结构和完整器官的无脊椎动物(双壳类、无脊椎动物、无脊椎动物和无脊椎动物)进行快速(从几秒到几分钟)和均匀的全身光学清除的方法。我们制定了一套统一的方案,先用二甲基亚砜(DMSO)对动物进行免疫染色,然后用苯甲醇/苯甲酸苄酯(BABB)对其进行光学清除。共聚焦显微光谱分析显示,该方案可将荧光信号提高 2 个数量级,将光散射降低 2 个数量级,从而加速全身共聚焦生物成像。此外,通过跟踪 0.3 秒分辨率的光学清除时间,我们发现清除过程是由贡珀茨增长函数描述的,从而确定了清除的物理机制及其光学参数。因此,我们能够详细识别和描述不同无脊椎动物以前未知的神经结构,为神经科学的发现铺平了道路。

3D Optical Reconstruction of the Nervous System of the Whole-Body Marine Invertebrates

3D Optical Reconstruction of the Nervous System of the Whole-Body Marine Invertebrates

Optical clearing of invertebrates, the number of species of which is 20 times greater than that of vertebrates, is of fundamental and applied interest for neuroscience in general. Herein, the optical clearing of invertebrates to identify their morphology and neurostructure remains unrealized as of yet. Here, we report on fast (from a few seconds to minutes) and uniform whole-body optical clearing of invertebrates (bivalves, nemertines, annelids, and anomura) of any age and thickness (up to 2 cm) possessing complicated structures and integuments. We developed the protocol unifying dimethyl sulfoxide (DMSO)-based immunostaining of the animals followed by their optical clearing with benzyl alcohol/benzyl benzoate (BABB). Confocal microspectroscopy revealed that the protocol provides an increase of the fluorescence signal by 2 orders of magnitude and decrease of the light scattering by 2 orders of magnitude, thereby accelerating the confocal bioimaging of the whole body. Moreover, by tracking the optical clearing over time with 0.3 s resolution, we revealed that the clearing process is described by the Gompertz growth function, allowing us to determine the physical mechanism of the clearing and its optical parameters. Thereby, we were able to identify in detail and to describe previously unknown neurostructures of different invertebrate animals, paving the way to discovery in neuroscience.
