神经通讯协调了各种行为,然而,尽管做出了令人印象深刻的努力,但由于现有监测工具的限制,描绘神经调制通讯的传输特性仍然是一项艰巨的任务。最近开发的遗传编码神经递质传感器,当与超分辨和去卷积显微技术相结合时,使神经调节传递的第一个微米和纳米可视化成为可能。在这里,我们通过介绍这种图像分析方法的生物物理基础、实用解决方案、生物学验证和广泛的适用性来介绍这种方法。该报告说明了该方法如何解决神经调节传递的基本突触特性,以及新数据揭示了啮齿动物和人类神经调节的意想不到的精细控制和精确度。这些发现提出了在了解神经调节传递方面取得快速进展的前景,神经调节传递对于解决各种行为和疾病的生理或发病机制至关重要。
Neural communication orchestrates a variety of behaviors, yet despite impressive effort, delineating transmission properties of neuromodulatory communication remains a daunting task due to limitations of available monitoring tools. Recently developed genetically encoded neurotransmitter sensors, when combined with superresolution and deconvolution microscopic techniques, enable the first micro- and nano-scopic visualization of neuromodulatory transmission. Here we introduce this image analysis method by presenting its biophysical foundation, practical solutions, biological validation, and broad applicability. The presentation illustrates how the method resolves fundamental synaptic properties of neuromodulatory transmission, and the new data unveil unexpected fine control and precision of rodent and human neuromodulation. The findings raise the prospect of rapid advances in the understanding of neuromodulatory transmission essential for resolving the physiology or pathogenesis of various behaviors and diseases.
