[Abstract] Myeloid progenitors in the bone marrow generate monocytes, macrophages, granulocytes and most dendritic cells. Even though these innate immune cells are part of the same lineage, each cell type plays a specific and critical role in tissue development, host defense and the generation of adaptive immunity. Protocols have been developed in the past to differentiate myeloid cell types from bone marrow cells, enabling functional investigation and furthering our understanding about their contribution to mammalian physiology. In this protocol, we describe a simple and rapid method to isolate monocytes from murine bone marrow, culture them for up to 5 days and lastly, differentiate them into bone marrow derived macrophages (Figure 1).

[摘要] [摘要]骨髓中的骨髓祖细胞产生单核细胞，巨噬细胞，粒细胞和大多数树突状细胞。即使这些先天免疫细胞是同一谱系的一部分，每种细胞类型在组织发育，宿主防御和适应性免疫的产生中也发挥着特定而关键的作用。过去已经开发出区分骨髓细胞和骨髓细胞的协议，以进行功能研究并加深我们对它们对哺乳动物生理学贡献的理解。在该协议中，我们描述了一种简单快速的方法，可从鼠骨髓中分离单核细胞，将其培养长达5天，最后，将它们分化为源自骨髓的巨噬细胞（图1）。

[Abstract] Many RNA viruses are found in protozoan parasites. They can be responsible for more serious pathology or treatment failure. For the detection of viral double-stranded RNA (dsRNA), sequence-dependent and -independent methods are available, such as quantitative real-time PCR and immunofluorescence, dot blot, ELISA or sequencing. The technique presented here is sequence-independent and is well detailed in the following protocol, taking the example of Leishmania RNA virus (LRV) in Leishmania guyanensis (Lgy) species. To summarise, the protocol is divided into four major steps: RNA extraction from the parasites, RNA purification, enzymatic digestions with DNase I and Nuclease S1, and visualization by gel electrophoresis. This method can be used to detect other viral ...
[摘要] [摘要 ] 原生动物寄生虫中发现了许多RNA病毒，它们可能导致更严重的病理或治疗失败。对于病毒双链RNA（dsRNA）的检测，有序列依赖性和非依赖性方法，例如定量实时PCR和免疫荧光，斑点印迹，ELISA或测序。此处介绍的技术是与序列无关的，并且在以下协议中进行了详细说明，以利什曼原虫（Legymania guyanensis）（Lgy ）中的利什曼原虫RNA病毒（LRV）为例 概括地说，该协议分为四个主要步骤：从寄生虫中提取RNA，RNA纯化，使用DNase I和Nuclease S1进行图解消化以及通过凝胶电泳进行可视化。该方法可用于检测其他病毒dsRNA它提供了一个额外的工具，可以对先前引用的其他技术进行补充，并且很容易实现。
[背景 ] 广泛的多样性RNA病毒中存在的原生动物寄生虫一直都有详细记载（王和王，1991;戈什等人，2011;桑戈等人。2014;碱液等人，2016年Akopyants 等人2016 ; Fernandez- Presas 等人，2017; Grybchuk 。等人。，2018）。此外，这些病毒已经被描述为潜在的毒力因子（Fichorova 等人，2013; EL- Gayar 。等人，2016; 拉特等。，2019）特别值得注意的，存在的内共生体。利什曼原虫RNA病毒（LRV），A ...
