Organotypic Brain Cultures: A Framework for Studying CNS Infection by Neurotropic Viruses and Screening Antiviral Drugs

[Abstract]  According to the World Health Organization (WHO), at least 50% of emerging viruses endowed with pathogenicity in humans can infect the Central Nervous System (CNS) with induction of encephalitis and other neurologic diseases (Taylor et al., 2001; Olival and Daszak, 2005). While neurological diseases are progressively documented, the underlying cellular and molecular mechanisms involved in virus infection and dissemination within the CNS are still poorly understood (Swanson and McGavern, 2015; Ludlow et al., 2016). For example, measles virus (MeV) can infect neural cells, and ... [摘要]  根据世界卫生组织(WHO)的统计,至少有50%的新发病毒具有致病性,可感染中枢神经系统(CNS),并诱发脑炎和其他神经系统疾病(Taylor et al。 >,2001; Olival和Daszak,2005)。虽然神经系统疾病逐渐被记录下来,但涉及病毒感染和在CNS内传播的潜在细胞和分子机制仍然知之甚少(Swanson and McGavern,2015; Ludlow等人,2016)。例如,麻疹病毒(MeV)可以感染神经细胞,并在原发感染后几个月至数年导致持续的脑感染,导致致死性脑炎,而没有可用的治疗(Reuter和Schneider-Schaulies,2010; Laksono等人。,2016)。器官型脑文化(OBC)是病毒学领域的一个合适的模型,以更好地理解中枢神经系统感染。实际上,它不仅可以研究中枢神经系统内嗜神经病毒的感染和传播,而且还可以作为创新性抗病毒策略或分子的筛选模型,如我们最近发表的有关融合抑制肽和HSP90伴侣蛋白活性抑制剂的研究, 17-DMAG(Welsch等人,2013; ...

Peroxisome Motility Measurement and Quantification Assay

[Abstract]  Organelle movement, distribution and interaction contribute to the organisation of the eukaryotic cell. Peroxisomes are multifunctional organelles which contribute to cellular lipid metabolism and ROS homeostasis. They distribute uniformly in mammalian cells and move along microtubules via kinesin and dynein motors. Their metabolic cooperation with mitochondria and the endoplasmic reticulum (ER) is essential for the β-oxidation of fatty acids and the synthesis of myelin lipids and polyunsaturated fatty acids. A key assay to assess peroxisome motility in mammalian cells is the expression of a ... [摘要]  细胞器运动,分布和相互作用有助于真核细胞的组织。过氧化物酶体是有助于细胞脂质代谢和ROS稳态的多功能细胞器。它们在哺乳动物细胞中均匀分布,并通过驱动蛋白和动力蛋白电动机沿微管移动。他们与线粒体和内质网(ER)的代谢合作对脂肪酸的β-氧化和髓鞘脂质和多不饱和脂肪酸的合成至关重要。评估哺乳动物细胞中过氧化物酶体运动性的关键测定是具有过氧化物酶体靶向信号(例如GFP-PTS1)的荧光融合蛋白的表达,其靶向过氧化物酶体基质并允许过氧化物酶体的活细胞成像。在这里,我们首先提出了用过氧化物酶体标记物EGFP-SKL转染培养的哺乳动物细胞的方案,以观察活细胞中的过氧化物酶体。这种方法揭示了过氧化物酶体的不同运动行为和对过氧化物酶体膜动力学的新见解(Rapp等,1996; Wiemer等,1997; ...
