[Abstract]  Metabolomic is an emerging field of system biology. Lipidomic, a branch of metabolomic, aims to characterize lipophilic metabolites in biological systems. Caenorhabditis elegans (C. elegans) is a genetically tractable and versatile animal model for novel discovery of lipid metabolism. In addition, C. elegans embryo is simple and homogeneous. Here, we demonstrate detailed procedures of C. elegans culture, embryo isolation, lipid extraction and metabolomic data analysis. [摘要]  在心肌梗死(MI)中,许多心肌细胞凋亡。 这些凋亡心肌细胞被吞噬细胞迅速吞噬。 如果死细胞没有被吞没,其有害物质被释放到外面,导致炎症的诱导。 因此,需要去除这些死细胞。 然而,每个吞噬细胞类型对梗塞心脏中凋亡细胞的去除的贡献仍未解决。 在这里,我们描述了吞噬作用测定的体外方案来比较心脏巨噬细胞和心脏肌成纤维细胞的吞噬能力。
【背景】长期以来一直认为,心脏巨噬细胞消除了在失败的心脏中产生的凋亡细胞。 然而,我们发现负责组织纤维化的心脏肌成纤维细胞也具有在MI后吞噬凋亡细胞的能力(Nakaya等,2017)。 这一发现促使我们比较心脏巨噬细胞和心脏肌成纤维细胞的吞噬能力。 在这里,我们提供了一个详细的体外吞噬试验方案来评估吞噬吞噬的程度。

Staphylococcus aureus Killing Assay of Caenorhabditis elegans

[Abstract]  The Gram-positive bacterium Staphylococcus aureus is a human pathogen that displays virulence towards the nematode Caenorhabditis elegans. This property can be used to discover genes that are important for virulence in humans, because S. aureus possesses common virulence factors that are used in C. elegans and in humans to cause disease. S. aureus colonizes the C. elegans intestine, establishes an infection, and causes pathogenesis of the intestinal epithelium that ultimately kills the infected animal after 3 to 4 days (Sifri et al., 2003; Irazoqui et al., 2008; Irazoqui et al., 2010). The protocol described here is used to establish the rate of S. aureus-induced C. elegans death, which ... [摘要]  革兰氏阳性菌金黄色葡萄球菌是一种人类病原体,对线虫秀丽隐杆线虫显示毒力。 这种性质可用于发现对人类毒力重要的基因,因为金黄色葡萄球菌具有在线虫和人类中引起疾病的常见的毒力因子。 金黄色葡萄球菌定殖线虫,建立感染,并引起肠上皮的发病机制,最终在3至4天后杀死感染的动物(Sifri等,2003; Irazoqui et al。,2008; Irazoqui et al ,,2010)。 这里描述的方案用于确定金黄色葡萄球菌诱导的秀丽隐杆线虫死亡率,其允许野生型和突变株的比较,从而最终有助于鉴定金黄色葡萄球菌毒力或C 线虫主机防御。 该测定法也可用于抗菌药物发现。
