[Abstract]  Phagocytosis of invading pathogens and their subsequent clearance in lysosomes is important for organismal fitness. We have devised the following protocol to extract phagocytic hemocytes from wild-type and mutant Drosophila larvae and infect the isolated hemocytes with GFP-labeled E. coli to measure the rate of phagocytosis and degradation within individual hemocytes over time. [摘要]  入侵病原体的吞噬作用及其随后在溶酶体中的清除对于有机体适应性是重要的。我们设计了以下方案从野生型和突变型果蝇幼虫中提取吞噬性血细胞,并用GFP标记的E感染分离的血细胞。大肠杆菌以测量个体血细胞内吞噬和降解的速度。

背景 下面描述的实验可用于研究吞噬体的生物发生,成熟和向溶酶体的递送。细菌积累已经在免疫受损的果蝇的背景下得到充分的研究,其具有IMD或Toll信号传导中的缺陷,并导致抗微生物肽的表达降低(例如,Lemaitre和Hoffmann ,2007; Kleino和Silverman,2014)。细菌感染的细胞响应在果蝇中的研究较少,大多数研究集中于干扰血细胞对细菌的最初吞噬吞噬的突变(Kocks等人,2005年) ;帕森斯和福利,2016)。这种细菌摄取是直接使用FACS分析进行测量(Tirouvanziam等人,2004)。然而,对于吞噬体成熟的详细分析,我们发现检查附着在玻璃盖板上的个体血细胞是有利的(Akbar等人,2011; Rahman等人。 ,2012; Akbar等人,2016),因为这个过程为我们研究吞噬体成熟提供了时间和空间分辨率的最佳组合。

[Abstract]  This protocol aims to study intercellular transport of mitochondria, dynamic cellular organelles via tunnelling nanotubes (TNT), a cell membrane extension of cytoskeletal elements. The nanotubular bridges or the tunnelling nanotube highways are one of the emerging new cell-to-cell communication systems which mediates exchange of cellular materials, most importantly as in our observation, mitochondria. Mesenchymal stem cells (MSC) have been well studied to be endowed with a highly efficient intercellular mitochondrial donation ability and this property is now proven crucial to its functional role of rescue in cellular therapy. [摘要]  此协议旨在研究线粒体,动态细胞器通过隧道纳米管(TNT),细胞骨架元素的细胞膜扩展的细胞间运输。 纳米管桥或隧道纳米管高速公路是新兴的新的细胞到细胞通信系统之一,其介导细胞材料的交换,最重要的是在我们的观察中,线粒体。 间充质干细胞(MSC)已经被充分研究以赋予高效的细胞间线粒体捐赠能力,并且这种性质现在被证明对于其在细胞治疗中的挽救的功能作用是至关重要的。
