This paper outlines the selection of NAMs, including in vitro assays using primary rat cortical neurons, zebrafish embryos, and . These assays aim to assess neurotoxic endpoints such as neuronal activity and behavioral responses. Microelectrode array recordings of rat cortical neurons provide insights into the impact of botanical extracts on neuronal function, while the zebrafish embryos and assays evaluate neurobehavioral responses. The paper also provides an account of the selection of botanical case studies based on expert judgment and existing neuroactivity/toxicity information. The proposed battery of assays will be tested with these case studies to evaluate their utility for neurotoxicity screening.
The complexity of botanicals necessitates the use of multiple NAMs for effective neurotoxicity screening. This paper discusses the evaluation of methodologies to develop a robust framework for evaluating botanical safety, including complex neuronal models and key neurodevelopmental process assays. It aims to establish a comprehensive screening framework.
本文概述了 NAMs 的选择,包括使用原代大鼠皮质神经元、斑马鱼胚胎和进行的体外检测。这些检测旨在评估神经毒性终点,如神经元活性和行为反应。大鼠皮质神经元的微电极阵列记录提供了关于植物提取物对神经元功能影响的见解,而斑马鱼胚胎和检测则评估神经行为反应。本文还介绍了基于专家判断和现有神经活性/毒性信息选择植物案例研究的情况。拟议的检测试剂盒将与这些案例研究一起进行测试,以评估其用于神经毒性筛选的效用。
