Analysis of TORC1-body Formation in Budding Yeast

[Abstract]  

The Target of Rapamycin kinase Complex I (TORC1) is the master regulator of cell growth and metabolism in eukaryotes. In the presence of pro-growth hormones and abundant nutrients, TORC1 is active and drives protein, lipid, and nucleotide synthesis by phosphorylating a wide range of proteins. In contrast, when nitrogen and/or glucose levels fall, TORC1 is inhibited, causing the cell to switch from anabolic to catabolic metabolism, and eventually enter a quiescent state. In the budding yeast Saccharomyces cerevisiae, TORC1 inhibition triggers the movement of TORC1 from its position around the vacuole to a single focus/body on the edge of the vacuolar membrane. This relocalization depends on the activity of numerous key TORC1 regulators and thus analysis of TORC1 localization can be used to

[摘要]  [摘要]雷帕霉素激酶复合体I(TORC1)的靶标是真核生物中细胞生长和代谢的主要调节剂。在促生长激素和丰富营养素的存在下,TORC1活跃并通过磷酸化多种蛋白质来驱动蛋白质,脂质和核苷酸合成。相反,当氮和/或葡萄糖水平下降时,TORC1被抑制,导致细胞从合成代谢转换为分解代谢,并最终进入静止状态。在发芽酵母中酿酒酵母 抑制TORC1会触发TORC1从其在液泡周围的位置移动到液泡膜边缘的单个焦点/物体。这种重新定位取决于许多关键的TORC1调节子的活动,因此可以使用TORC1定位分析来跟踪通过TORC1途径发出的信号。在这里,我们提供了使用荧光显微镜测量TORC1(特别是Kog1-YFP)重新定位/信号传递的详细协议。重点放在确保以下方面的程序上:(1)尽管葡萄糖和氮饥饿期间它们相对较低的荧光和自发荧光灶的积累,但仍正确地识别(并计数)TORC1抗体;(2)在每次实验开始时,使细胞保持对数生长期,以便正确监测TORC1体形成的动力学;(3)使用适当的荧光标签来避免检查错误定位的TORC1。

[背景]雷帕霉素的靶激酶复合物I(TORC1 )是真核生物的细胞生长控制网络中的中央轮毂(Loewith和Hall,2011;冈萨雷斯和Hall,2017; Liu和萨巴蒂尼,2020 ...

[Abstract]  Double-stranded RNA is a potent pathogen-associated molecular pattern (PAMP) produced as a by-product of viral replication and a well-known hallmark of viral infection. Viral dsRNAs can be released from infected cells into the extracellular space and internalized by neighboring cells via endocytosis. Mammals possess multiple pattern recognition receptors (PRRs) capable of detecting viral dsRNAs such as endosomal toll-like receptor 3 (TLR3) and cytosolic RIG-I-like receptors (RLRs) which lead to the production of type I interferons (IFNs). Thus, intracellular localization of viral dsRNA can provide insight into the downstream signaling pathways leading to innate immune activation. Here, we describe a quantitative method for measuring extracellular dsRNA uptake and visualizing subcellular ... [摘要]  双链RNA是一种有效的病原体相关分子模式(PAMP),作为病毒复制的副产物和病毒感染的众所周知的标志产生。 病毒dsRNA可以从感染的细胞释放到细胞外空间并通过胞吞作用被邻近细胞内化。 哺乳动物具有能够检测导致产生I型干扰素(IFN)的病毒dsRNA(例如内体Toll样受体3(TLR3)和胞质RIG-1样受体(RLR))的多模式识别受体(PRR)。 因此,病毒dsRNA的细胞内定位可以提供对导致先天免疫激活的下游信号传导途径的了解。 在这里,我们描述了一种测量细胞外dsRNA摄取和分别通过流式细胞仪和共聚焦显微镜观察内化dsRNA的亚细胞定位的定量方法。

【背景】双链RNA(dsRNA)是病毒复制的常见副产物,通过产生I型干扰素(IFN)和其他促炎细胞因子(Nellimarla和Mossman,2014)是抗病毒免疫的有效激活剂。病毒的dsRNA通过TLR3核内体内所感测(松本等人,2003年)或在由RIG-I样受体(RLRS),RIG-I和MDA-5(加藤等人,2006)。在裂解感染,这些dsRNA可以被释放到细胞外空间,它们结合于相邻小区,如A类清道夫受体(SR-A)和RAFTLIN表面受体,并且随后经由网格蛋白介导的内吞作用内在化(伊藤制 2008; DeWitte-Orr等人,2010; Watanabe等人,2011; Dansako等人,, ...
