Studying the Role of Microglia in Neurodegeneration and Axonal Regeneration in the Murine Visual System

[Abstract]  Microglia reside in the central nervous system (CNS) and are involved in the maintenance of the physiologic state. They constantly survey their environment for pathologic alterations associated with injury or diseases. For decades, researchers have investigated the role of microglia under different pathologic conditions, using approaches aiming to inhibit or eliminate these phagocytic cells. However, until recently, methods have failed to achieve complete depletion. Moreover, treatments often affected other cells, making unequivocal conclusions from these studies difficult. Recently, we have ... [摘要]  小胶质细胞存在于中枢神经系统(CNS)中,并参与维持生理状态。他们不断调查他们的环境,以寻找与受伤或疾病相关的病理改变。几十年来,研究人员使用旨在抑制或消除这些吞噬细胞的方法,研究了小胶质细胞在不同病理条件下的作用。然而,直到最近,方法未能实现完全耗尽。此外,治疗通常会影响其他细胞,因此难以从这些研究中得出明确的结论。最近,我们已经表明,通过用含有食物的PLX5622口服治疗抑制集落刺激因子1受体(CSF1R)能够完全消除视网膜小胶质细胞并且几乎完全消除视神经中的小胶质细胞,而不影响外周巨噬细胞或其他细胞。使用这种方法,我们研究了小胶质细胞在视网膜神经保护中的作用以及在不同条件下受损视神经中的轴突再生。因此,这里提出的这种有效,可靠和易于使用的方案将使研究人员能够明确地研究小胶质细胞对神经变性和轴突再生的贡献。该方案还可以容易地扩展到视觉系统中的急性和慢性损伤或疾病的其他范例。

【背景】 小胶质细胞是中枢神经系统(CNS)的常驻免疫细胞,其持续扫描其环境以进行病理改变(Nimmerjahn et al。,2005)。在检测到这种情况后,小胶质细胞转变为活化状态并向其进行不同任务的来源迁移(Kreutzberg,1996; Davalos et ...

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; ...

Combination of Fluorescent in situ Hybridization (FISH) and Immunofluorescence Imaging for Detection of Cytokine Expression in Microglia/Macrophage Cells

[Abstract]  Microglia and macrophage cells are the primary producers of cytokines in response to neuroinflammatory processes. But these cytokines are also produced by other glial cells, endothelial cells, and neurons. It is essential to identify the cells that produce these cytokines to target their different levels of activation. We used dual RNAscope® fluorescence in situ hybridization (FISH) and immunohistochemistry (IHC) techniques to visualize the mRNA expression pattern of pro- and anti-inflammatory cytokines in microglia/macrophages cells. Using these methods, we can associate ... [摘要]  小神经胶质细胞和巨噬细胞是响应神经炎症过程的细胞因子的主要生产者。但是这些细胞因子也是由其他神经胶质细胞,内皮细胞和神经元产生的。鉴定产生这些细胞因子的细胞以靶向其不同水平的活化是至关重要的。我们使用双RNAscope荧光原位杂交(FISH)和免疫组织化学(IHC)技术来观察小胶质细胞/巨噬细胞中促炎细胞因子和抗炎细胞因子的mRNA表达模式细胞。使用这些方法,我们可以联合一个mRNA与特定的细胞类型时,通过免疫荧光与不同的细胞标志物结合。来自RNAscope探针的结果IL-1β,TNFα,TGFβ,IL-10或Arg1显示与小胶质细胞/巨噬细胞抗体的共定位。这些靶标探针显示出足够的灵敏度和特异性来检测mRNA表达。新的FISH检测技术结合免疫组化技术将有助于共同确定蛋白质和mRNA的定位,以及提供可靠的mRNA表达水平的量化。
【背景】mRNA原位杂交技术是一种有用的工具,其允许以细胞依赖性方式特异性和选择性标记脑切片中的RNA序列(Grabinski等人,2015 ...
