[Abstract]  Compared to tissue sectioning techniques, the technique of teasing single nerve fibers provides a better way to understand the structures of myelin sheaths and axons of the peripheral myelinated nerves. This protocol describes a method for preparation of teased single nerve fibers from rat sciatic nerve. In this protocol, fixed nerves are teased into single individual fibers and arranged onto adhesion microscope slides for further immuno-staining. [摘要]  与组织切片技术相比,单神经纤维的技术提供了更好的方法来了解髓鞘和外周髓鞘神经的轴突的结构。 该方案描述了一种从大鼠坐骨神经制备调节的单神经纤维的方法。 在该方案中,将固定的神经梳理成单个单独的纤维并排列在粘附显微镜载玻片上用于进一步的免疫染色。
【背景】外周神经系统中的雪旺氏细胞围绕轴突包裹以形成绝缘髓鞘,其允许动作电位的快速传导。 显着的多层髓鞘由精细的结构组成,包括紧密的鞘,施密特 - 兰特曼切口,Cajal带,内外侧mesaxons,以及在paranodal区域的结构。 为了阐明外周神经有髓纤维的正常和异常结构,需要使用切割的神经纤维。 拔牙纤维的方法已被广泛应用于人类和啮齿类动物周围神经的研究。 在这个协议中,我们描述了一种将周围神经分为单纤维的方法,用于对周围神经的轴突或髓鞘进行进一步的形态学研究。

Analysis of the Virulence of Uropathogenic Escherichia coli Strain CFT073 in the Murine Urinary Tract

[Abstract]  This urinary tract infection model was used to monitor the efficacy of a new virulence factor of the uropathogenic Escherichia coli strain CFT073 in vivo. The new virulence factor which we designated TIR-containing protein C (TcpC) blocks Toll-like receptor signaling and the NLRP3 inflammasome signaling cascade by interacting with key components of both pattern recognition receptor systems (Cirl et al., 2008; Waldhuber et al., 2016). We infected wild type and knock-out mice with wildtype CFT073 and a mutant CFT073 strain lacking tcpC. This protocol describes how the mice were infected, how CFT073 was prepared and how the infection was monitored. The protocol was derived from our previously published work and allowed us to demonstrate that TcpC ... [摘要]  该尿路感染模型被用于监测新生的致病性大肠杆菌菌株CFT073在体内的功效。我们指定含TIR的蛋白C(TcpC)的新的毒力因子通过与模式识别受体系统的关键组分相互作用来阻断Toll样受体信号传导和NLRP3炎性信号级联反应(Cirl等人)。 ,2008; Waldhuber等人,2016)。我们用野生型CFT073和缺乏tcpC的突变体CFT073菌株感染野生型和敲除小鼠。该协议描述了小鼠如何感染,如何制备CFT073以及如何监测感染。该方案源于我们以前发表的工作,并允许我们证明TcpC是一种强大的毒力因子,通过增加CFT073在尿液和肾脏中的细菌负担。此外,TcpC负责肾脓肿的发展,因为感染具有野生型但不是tcpC的缺乏CFT073突变体的小鼠引起这种并发症。

背景 尿路感染(UTIs)是全世界最常见的细菌感染(Dielubanza和Schaeffer,2011),主要是由欧洲病原大肠杆菌(UPEC)引起的(Zhang和Foxman,2003)。复发性感染率高(Dielubanza和Schaeffer,2011),抗生素抗性E的出现也有所增加。大肠杆菌菌株(Eurosurveillance editorial,2015)。因此,为了开发新的治疗剂,对宿主和细菌因子对尿路感染病理生理学的了解具有很高的相关性。
 鼠类UTI模型系统是主要使用的动物模型系统,用于研究UPEC分离株和细菌 ...
