Measuring Caenorhabditis elegans Sleep during the Transition to Adulthood Using a Microfluidics-based System

[Abstract]  C. elegans sleep during development is regulated by genes and cellular mechanisms that are conserved across the animal kingdom (Singh et al., 2014; Trojanowski and Raizen, 2016). C. elegans developmental sleep is usually assessed during the transition to adulthood, a 2.6 h time interval called lethargus (Raizen et al., 2008; Singh et al., 2011). During lethargus, animals cycle between periods of immobility (sleep bouts) and periods of active locomotion (motion bouts). Sleep bouts resemble sleep in other species based on behavioral criteria, ... [摘要]  C。发展过程中的线虫睡眠受到动物界保护的基因和细胞机制的限制(Singh等人,2014; Trojanowski和Raizen,2016)。 C。线虫发育睡眠通常在成年过渡期间进行评估,2.6h时间间隔称为lethargus(Raizen等人,2008; Singh等人, 2011)。在嗜睡期间,动物在不动的时期(睡眠开始)和积极运动时期(运动发作)之间循环。睡眠状态基于行为标准,包括停止进食和运动,增加唤醒阈值以响应感觉刺激,快速可逆性和对睡眠损失的稳​​态反应,类似于其他物种的睡眠。已经开发了几种用于在C中研究睡眠的测定法。 (Belfer等人,2013; Bringmann,2011; Nelson等人,2013; Raizen等人, 2008)。在这里,我们提供了一个详细的评估方案。线虫在lethargus期间睡眠,许多研究组已经成功使用,结合简单的微流体室,具有照明系统的低成本照相机和基于图像减法的计算分析。我们注意到,这个系统可以很容易地适应于评估任何小动物的睡眠。

背景 C。睡眠通常根据运动停止进行评估,这是整个动物界睡眠的常见特征。由于C期间睡眠发作的间歇性。线虫发育睡眠,计算机视觉通常用于跟踪C的活动。线虫在lethargus期间。动物被约束到单个焦平面以保持它们的焦点。因为C.线虫可以通过长时间的游泳用尽液体(Ghosh和Emmons,2008),C。线虫 ...

[Abstract]  In the Whole Spleen Flow Cytometry Assay, we used splenocytes directly ex vivo for stimulation with a variety of TLR ligands. The splenocytes were stimulated for a total of 4 hours, then stained for intracellular cytokines. We then examined cytokine production via flow cytometry. This allowed us to compare the responses of minimally manipulated primary macrophages/monocytes and conventional dendritic cells. [摘要]  在全脾流式细胞术测定中,我们直接使用脾细胞离体用各种TLR配体刺激。 将脾细胞刺激总共4小时,然后对细胞内细胞因子染色。 然后我们通过流式细胞术检查细胞因子产生。 这使我们能够比较最小操纵的原代巨噬细胞/单核细胞和常规树突状细胞的反应。
