[Abstract]  Here we provide a detailed step-by-step protocol for using lentivirus to manipulate miRNA expression in Area X of juvenile zebra finches and for analyzing the consequences on song learning and song performance. This protocol has four parts: 1) making the lentiviral construct to overexpress miRNA miR-9; 2) packaging the lentiviral vector; 3) stereotaxic injection of the lentivirus into Area X of juvenile zebra finches; 4) analysis of song learning and song performance in juvenile and adult zebra finches. These methods complement the methods employed in recent works that showed changing FoxP2 gene expression in Area X with lentivirus or adeno-associated virus leads to impairments in song behavior. [摘要]  在这里，我们提供了一个详细的逐步协议，用于使用慢病毒操纵幼年斑胸草雀X区的miRNA表达，并分析对歌曲学习和歌曲表现的影响。 该方案有四个部分：1）使慢病毒构建体过表达miRNA miR-9; 2）包装慢病毒载体; 3）将慢病毒立体定位注入少年斑胸草雀X区; 4）青少年和成年斑马雀的歌曲学习和歌曲表演分析。 这些方法补充了近期工作中使用的方法，这些方法显示，在区域X中用慢病毒或腺相关病毒改变 FoxP2 基因表达导致歌曲行为的损害。

【背景】具有良好特征的歌曲行为和基础神经回路的斑胸草雀提供了独特的动物模型来研究声音通信和相关感觉 - 运动学习的神经机制。近年来，一些实验室开始使用病毒载体来操纵斑胸草雀脑中的基因表达并研究其功能后果。这些努力通过对 FoxP2 基因的研究得到了最好的说明，该基因编码叉头盒p2转录因子。 FoxP2蛋白控制着数百个在神经系统发育中起重要作用的下游基因的表达。人类 FoxP2 基因的突变导致言语和语言障碍（Lai et al。，2001）。在鸣禽中，斑马雀X区域的 FoxP2 基因的敲除或过表达，对于声乐学习至关重要的基底神经节核，严重损害了歌曲的行为（Haesler et al。， 2007; Murugan et al。，2013; Heston and ...

[Abstract]  Eosinophils are multifunctional effector cells implicated in the pathogenesis of a variety of diseases including asthma, eosinophil gastrointestinal disorders and helminth infection. Mouse bone marrow derived progenitor cells can be differentiated into eosinophils following IL-5 exposure. These bone marrow derived eosinophils are fully differentiated at the end of a 14 day culture based on morphology and expression of molecular markers.
[摘要]  嗜酸性粒细胞是涉及多种疾病的发病机理的多功能效应细胞，包括哮喘，嗜酸性粒细胞胃肠道疾病和蠕虫感染。 小鼠骨髓来源的祖细胞可以在IL-5暴露后分化成嗜酸性粒细胞。 这些骨髓衍生的嗜酸性粒细胞在14天培养结束时基于分子标志物的形态学和表达完全分化。
