Aldicarb-induced Paralysis Assay to Determine Defects in Synaptic Transmission in Caenorhabditis elegans

[Abstract]  Aldicarb treatment causes an accumulation of acetylcholine in the synaptic cleft of the neuromuscular junction, resulting in sustained muscle activation and eventually paralysis. Aldicarb-induced paralysis assay is an easy and fast method to determine whether synaptic transmission of a C. elegans mutant of interest is altered. This assay is based on the correlation of the rate of neurotransmitter release with the rate of paralysis. In this protocol, we describe a method for simultaneously assessing the aldicarb sensitivity of animals with different genotypes. [摘要]  涕灭威的治疗导致神经肌肉接头突触裂缝中的乙酰胆碱积聚,导致持续的肌肉活化并最终导致麻痹。 涕灭威诱导的麻痹测定是确定是否突触传播的一种简单且快速的方法。 线虫兴趣突变体被改变。 该测定是基于神经递质释放速率与麻痹率的相关性。 在该方案中,我们描述了同时评估具有不同基因型的动物的涕灭威敏感性的方法。
【背景】突触传递通过动作电位到达突触前末端而开始,这又导致神经递质的释放。释放的神经递质结合并激活突触后受体(Sudhof,2013)。 ℃。线虫运动由乙酰胆碱释放兴奋性运动神经元和GABA(γ-氨基丁酸)释放抑制运动神经元控制(Richmond和Jorgensen,1999; ...

Artificial Optogenetic TRN Stimulation of C. elegans

[Abstract]  Optogenetics is a powerful tool for manipulating neuronal activity with high temporal and spatial precision. In the nematode C. elegans optogentics is especially useful and easy to apply. This is because C. elegans is translucent, so its neurons are highly accessible to optic stimulation. In addition, many of its neurons can be exclusively targeted using cell-specific promoters. We have recently taken advantage of optogenetics to deliver artificial patterns of prolonged activation to a class of mechanosensory neurons, called touch receptor neurons (TRNs) in worms that lack touch sensation due to a genetic mutation. Our aim was to examine whether we can counteract the effects of sensory loss by artificially activating the sensory neurons. Here we describe in detail the ... [摘要]  光遗传学是一个强大的工具,用于操纵具有高时间和空间精度的神经元活动。在线虫中。 elegans 光兴剂是特别有用和容易应用。这是因为 C。 elegans 是半透明的,所以它的神经元高度可及光学刺激。此外,其许多神经元可以使用细胞特异性启动子专门靶向。我们最近利用光学学提供长时间激活的人工模式到一类机械感觉神经元,称为触摸受体神经元(TRNs)在蠕虫缺乏触摸感觉由于基因突变。我们的目的是检查我们是否可以通过人为激活感觉神经元抵消感觉损失的影响。在这里我们详细描述我们使用的协议的各个组件。这包括暴露蠕虫表示光敏离子通道Channelrohdopsin 2(ChR2)在TRNs长期随机闪光。

[背景] 神经元的人工光遗传刺激(或沉默)已经在神经科学研究中广泛使用。强大的模型生物,C。 (Nagel等人,2005),并且多个组已经开发了用于以高时间和空间精度递送人工简单模式的刺激的一系列技术(Leifer等人,2011; Stirman等人,2011)和与行为结合(Kocabas等人,2012)和钙成像(Guo等人,2009)或电生理学(Lindsay等人,2011)读数。我们有兴趣建立一种长期刺激方案,其将取代被剥夺感觉输入的机械感觉神经元中的自然正在进行的活动(Rabinowitch等人,2016)。我们的协议集成了以前的C。 elegans ...
