Detection of Cell Death in Planarians

[Abstract]  Planarians are freshwater flatworms, well known for their ability to regenerate a complete organism from any piece of their body. Furthermore, planarians are constantly growing and degrowing throughout their lives, maintaining a functional and proportioned body. These properties rely on the presence of a population of adult stem cells and on the tight control of their cell renewal, which is based on the balance between the proliferation of new cells and their differentiation, and the death of unnecessary cells. Due to the importance of these two processes in planarian biology, over the years, researchers have optimized molecular techniques to detect both cell proliferation and cell death in planarians. Here, we present the two main protocols currently used for cell death detection and ... [摘要]  涡虫是淡水扁虫,因其能够从身体的任何部分再生完整的有机体而闻名。 此外,涡虫在其一生中不断生长和去除,保持功能和比例的身体。 这些特性依赖于成体干细胞群的存在以及对细胞更新的严格控制,其基于新细胞增殖与其分化之间的平衡以及不必要细胞的死亡。 由于这两个过程在涡虫生物学中的重要性,多年来,研究人员已经优化了分子技术,以检测涡虫中的细胞增殖和细胞死亡。 在这里,我们提出了目前用于细胞死亡检测和量化的两种主要方案:Caspase-3活性定量和TUNEL分析。
【背景】成体生物体中的细胞更新是基于三个过程的复杂机制:(a)通过细胞死亡消除选定的细胞; (b)通过细胞分裂取代已消除的细胞,通常涉及成体干细胞及其后代; (c)新生细胞的分化及其与先前存在的组织的整合(Pellettieri和Sanchez ...

[Abstract]  The prevalence of neurodegenerative diseases is increasing worldwide. Cerebrovascular disorders and/or conditions known to affect brain vasculature, such as diabetes, are well-known risk factors for neurodegenerative diseases. Thus, the evaluation of the brain vasculature is of great importance to better understand the mechanisms underlying brain damage. We established a protocol for the isolation of brain vessels from rodents. This is a simple, non-enzymatic isolation protocol that allows us to perform comparative studies in different animal models of disease, helping understand the impact of several pathological conditions on brain vasculature and how those alterations predispose to neurodegenerative conditions. [摘要]  全世界神经退行性疾病的发病率正在增加。 已知会影响脑血管系统的脑血管疾病和/或病症,如糖尿病,是神经变性疾病的众所周知的危险因素。 因此,脑血管系统的评估对于更好地了解脑损伤的机制是非常重要的。 我们建立了从啮齿动物分离脑血管的方案。 这是一个简单的非酶分离方案,允许我们在不同的疾病动物模型中进行比较研究,帮助了解几种病理状况对脑血管系统的影响以及这些改变如何易于发生神经退行性疾病。
【背景】大脑高度依赖于通过庞大的血管网络到达的氧气和营养物质的不断供应。主要由微血管内皮细胞组成的血脑屏障(BBB),其包括脑内微血管以及周围结构,包括周细胞,星形胶质细胞和基底膜(Saraiva等,2016; Librizzi等,2017),保证控制稳态环境,保持脑细胞的健康。因此,研究如何干扰脑血管系统完整性的某些病理学是非常重要的。事实上,临床,成像,流行病学和神经病理学研究的有力证据证实了过去二十年来,脑血管疾病的存在在阿尔茨海默病(AD)和其他与衰老有关的痴呆中具有关键作用(Chui et al。,2006; Schneider et al。,2007; Gorelick et al。,2011; Wharton et al。,2011; Yarchoan et al。,2012; Bennett et al。,2013; DeCarli,2013; Toledo et ...

Axenic Culture of Sclerotinia sclerotiorum and Preparation of Sclerotinia Culture Filtrate Elicitor 1 (SCFE1)-containing Fractions, Triggering Immune Responses in Arabidopsis thaliana

[Abstract]  The necrotrophic white mold fungus Sclerotinia sclerotiorum (S. sclerotiorum) is pathogenic to a broad range of plant species, including the Brassicaceae model plant Arabidopsis thaliana (Boland and Hall, 1994; Bolton et al., 2006). In Arabidopsis thaliana (A. thaliana), the semi-purified proteinaceous S. sclerotinorum elicitor SCFE1 (Sclerotinia culture filtrate elicitor 1) is sensed at the plasma membrane by the receptor-like protein RLP30 and triggers strong immune responses (Zhang et al., 2013), similar to the bacterial elicitor flagellin (Felix et al., 1999). Elicitation of plant defenses with SCFE1 is a tool to dissect the signaling pathway involving RLP30 and to study immunity to necrotrophic ... [摘要]  坏死性白霉菌真菌(Sclerotinia sclerotiorum)(核盘菌)对广泛的植物物种(包括十字花科模式植物拟南芥(Arabidopsis thaliana))具有致病性, (Boland和Hall,1994; Bolton等人,2006)。在拟南芥中(thaliana),是半纯化的蛋白质。通过受体样蛋白RLP30在质膜感测核盘菌诱导物SCFE1(核盘菌属培养物滤液诱发物1),并且引发强烈的免疫应答(Zhang等人。,2013),类似于细菌激发剂鞭毛蛋白(Felix等人,1999)。植物防御与SCFE1的诱导是一个工具,以解剖涉及RLP30的信号通路和研究对坏死性真菌的免疫。在这里,我们描述一个简单的协议来生长。菌核。此外,我们提出了一种两步液相色谱法从培养滤液中部分纯化SCFE1的方法(图1A-B)。通过气相色谱法测定植物应激激素乙烯的发射作为生物测定,以在整个纯化程序中监测级分中的激发剂活性(图1C)。
