Assessing the Efficacy of Small Molecule Inhibitors in a Mouse Model of Persistent Norovirus Infection

[Abstract]  Human norovirus is the most common cause of acute gastroenteritis worldwide, resulting in estimated mortality of ~210,000 each year, of whom most are children under the age of five. However, norovirus can infect people of all age groups. There is a risk of prolonged infection in children, the elderly and patients who are immunocompromised. To study the inhibition of persistent norovirus replication by small molecule antivirals in vivo, we used a murine norovirus CR6 strain (MNV.CR6). We demonstrated earlier that efficient small molecules can reduce viral shedding in the stool of infected mice. Here we present how to generate the MNV.CR6 virus stock, infect type I and II interferon receptor knockout AG129 mice via oral gavage, administer antivirals to mice, and quantify viral ... [摘要]  人类诺瓦克病毒是全球急性胃肠炎最常见的原因,估计每年约有210,000人死亡,其中大部分是5岁以下的儿童。 然而,诺如病毒可以感染所有年龄组的人。 儿童,老年人和免疫功能低下的患者有长期感染的风险。 为研究体内小分子抗病毒剂对持续诺如病毒复制的抑制作用,我们使用鼠诺沃克病毒CR6株(MNV.CR6)。 我们之前表明,高效小分子可以减少感染小鼠粪便中的病毒脱落。 在这里,我们介绍如何产生MNV.CR6病毒,通过口服灌胃感染I型和II型干扰素受体敲除AG129小鼠,给小鼠施用抗病毒药物,并量化这些小鼠粪便中的病毒基因组拷贝。

【背景】人诺瓦克病毒是胃肠炎的重要原因。尽管大多数诺罗病毒感染是急性和自限性的,但是在具有免疫缺陷状态的患者中,尤其是在实体器官和造血干细胞移植受体,接受化疗的患者和患有AIDS的患者中,感染可能变成慢性的(Westhoff等人, / em>,2009; Green,2014; Angarone 等。,2016)。在幼儿和老年人中也观察到延长的诺如病毒感染,导致疾病持续时间增加,排便增加和病毒脱落长达47天(Murata等人,2007; ...

Plate Assay to Determine Caenorhabditis elegans Response to Water Soluble and Volatile Chemicals

[Abstract]  The nematode Caenorhabditis elegans is widely used for behavioral studies ranging from simple chemosensation to associative learning and memory. It is vital for such studies to determine optimal concentrations of attractive and aversive chemicals that C. elegans can sense. Here we describe a resource localization assay in which a chemical compound of interest is placed in two compartments of a quadrant plate in order to determine optimal concentrations of the chemical in behavioral studies. Using the assay, we determined the optimal concentration of a water-soluble attractant, KCl, as an unconditioned stimulus for the study of associative learning and memory. In this protocol, we also describe a chemotaxis assay using a square agar plate spotted with an aversive ... [摘要]  线虫<秀秀隐杆线虫广泛用于从简单的化学感应到联想学习和记忆的行为研究。 这些研究对于确定吸引和厌恶化学物质的最佳浓度至关重要。="" 线虫可以感觉到。="" 在这里我们描述了一种资源定位测定法,其中将感兴趣的化学化合物置于象限板的两个隔室中以确定化学品在行为研究中的最佳浓度。="" 使用该测定,我们确定了水溶性引诱剂kcl的最佳浓度,作为研究关联学习和记忆的无条件刺激。="">

【背景】线虫线虫广泛用作动物行为研究的模式生物。 ℃。秀丽隐杆线虫感知主要由最大的化学感受器官(Ward,1973; Dusenbery,1974; Bargmann和Horvitz,1991; Bargmann等人)等介导的各种水溶性和挥发性化学物质。 1993)。行为研究必须确定可以被感知的化学物质的精确浓度。线虫。为了确定用于C的水溶性引诱剂的最佳浓度。线虫,Wicks等人(2000)使用象限琼脂平板进行行为测定,其中感兴趣的化学物质与琼脂在两个隔室中混合,并且该测定已广泛用于许多化学品(例如Jansen等人,2002; Ortiz等人,2009; Murayama和Maruyama,2013; Sassa&lt; em&gt; et al。,2013)。趋化性分析也被用于测量C的敏感性。 ...
