[Abstract]  Infection with Trypanosoma cruzi causes Chagas disease. The methods provided here allow for the quantification of T. cruzi in the liver, heart, and blood of intraperitoneally-infected mice and analysis of the killing activity of the cells infected with T. cruzi in vitro. [摘要]  感染克氏锥虫(Trypanosoma cruzi)引起恰加斯病(Chagas disease)。 这里提供的方法允许量化T。 克氏锥虫在感染腹腔的小鼠的肝脏,心脏和血液中分析,并分析克氏锥虫在体外感染的细胞的杀伤活性。
【背景】以慢性心肌病为特征的恰加斯病是由细胞内原生动物寄生虫克氏锥虫感染引起的(Bonney等人,2015年)。拉丁美洲大约有2000万人患有南美锥虫病(里贝罗等人,2012; Flavia Nardy等人,2015),已成为全球性的健康问题由于感染者的迁移(Andrade等人,2014; Garcia等人,2015; Requena-Mendez等人), 2015年)。已经开发了几种药物,如nifurtimox和benznidazole,用于治疗恰加斯病。然而,这些药物需要服用数月,并有严重的副作用(Viotti et al。,2009)。治疗的主要目的是抑制T。克鲁兹通过血液传播以及防止心力衰竭的发展。因此,定量T的协议。 cruzi 和 T。这里介绍的克鲁兹杀螨试验可能有助于发展南美锥虫病的新型诊断方法和治疗策略。

Measurement of PI4P Levels in Intact Chloroplasts Isolated from Arabidopsis thaliana

[Abstract]  Phosphatidylinositol 4-phosphate (PI4P), a major species of phosphoinositides, modulates many fundamental cellular processes. We have recently revealed that PI4P plays an important role in chloroplast division as a negative regulator. Despite its importance in chloroplasts, the content of PI4P in chloroplasts is very low and it is difficult to measure PI4P levels. In this protocol, we describe a simple method that we have developed for measurement of low level of PI4P in chloroplasts. Intact chloroplasts were isolated by a basic method using Percoll gradient centrifugation and acidic lipids were extracted from the isolated chloroplasts. The extracted acidic lipids including PI4P were spotted onto the membrane strip, which had been pre-spotted with PI4P standards and other ... [摘要]  磷脂酰肌醇4-磷酸(PI4P)是磷酸肌醇的主要种类,调节许多基本的细胞过程。 我们最近揭示PI4P在叶绿体分裂作为负调节器中发挥重要作用。 尽管其在叶绿体中的重要性,PI4P在叶绿体中的含量非常低,并且难以测量PI4P水平。 在这个协议,我们描述了一个简单的方法,我们已经开发测量叶绿体中的低水平的PI4P。 通过使用Percoll梯度离心的碱性方法分离完整的叶绿体,并从分离的叶绿体中提取酸性脂质。 将包括PI4P的提取的酸性脂质点样在膜条上,其已经用PI4P标准品和其它磷酸肌醇作为阴性对照预先点样。 使用PI4P结合蛋白检测膜上酸性脂质斑点中的PI4P。
