[Abstract]  The greater wax moth Galleria mellonella has emerged as an effective heterologous host to study fungal pathogenesis and the efficacy of promising antifungal drugs (Mylonakis et al., 2005; Li et al., 2013). Here, a methodology describing the Aspergillus nidulans infection in G. mellonella larvae, along with insect survival analysis, is reported. This protocol allowed the distinction between virulent A. nidulans strains (such as TNO2A3), which induced high larval mortality rates, to those in which gene deletion was accompanied by reduced ... [摘要]  作为一种有效的异源宿主,越来越多的蜡蛾已经出现了一种有效的异源宿主,用于研究真菌发病机制和有希望的抗真菌药物的功效(Mylonakis等人,2005; Li& et al。2013)。这里,描述了一种描述构巢曲霉感染的方法。 mellonella 幼虫与昆虫存活分析一起报道。该协议允许区分有毒的 A。造成高幼虫死亡率的构巢组织菌株(如TNO2A3)与基因缺失伴随着致病性降低的病例如ΔGCA和ΔSAA(Fernandes 等人,2016)。

背景 -G。 mellonella 是一种廉价的模型,易于处理,其先天免疫反应与哺乳动物免疫系统分享功能相似性。此外,感染真菌突变菌株的幼虫和小鼠表现出相似的存活率(Brennan等人,2002)。因此,幼虫构成了一种方便的动物宿主,用于在真菌发病机理分析中代替脊椎动物的使用。尽管昆虫模型具有所有优点,但只有少数报告显示了G中曲霉菌感染的作用。蜡螟。该协议描述了一种有效的方法,用于分析G中的构巢曲霉发病机制。 mellonella 幼虫。

[Abstract]  Filamentous fungi and bacteria form mixed-species biofilms in nature and diverse clinical contexts (Frey-Klett et al., 2011; Peleg et al., 2010). The interactions between fungi and bacteria, often mediated by secreted metabolites, have important ramifications for the biology of the interacting partners (Frey-Klett et al., 2011). This is particularly true for the bacterium Pseudomonas aeruginosa (P. aeruginosa) and the fungus Aspergillus fumigatus (A. fumigatus) which often reside in the same niche such as lungs of cystic fibrosis ... [摘要]  丝状真菌和细菌在自然界和不同的临床背景中形成混合物种生物膜(Frey-Klett等人,2011; Peleg等人,2010)。真菌和细菌之间的相互作用,通常由分泌的代谢物介导,对相互作用的伴侣的生物学具有重要的影响(Frey-Klett等人,2011)。对于绿脓假单胞菌(铜绿假单胞菌)和真菌烟曲霉( A。fumigatus >),其常常位于相同的位置,例如囊性纤维化(CF)患者的肺。一些研究报道了与p的共感染。铜绿和 烟曲霉可能导致相对于它们各自的单一物种感染的肺功能降低(Amin等人,2010; Peleg等人,2010)。代谢物提取和分析允许表征多微生物生物膜中的特定微生物代谢物。该方案描述了如何在固体培养基上制备假单胞菌属 - 曲霉菌共培养生物膜以准备代谢物提取。

[Abstract]  This method can be used to free and separate the mesophyll cells from Arabidopsis leaves. The protoplasts that are generated in this way can be used for transient expression for protein activity and subcellular localization assays. [摘要]  该方法介绍从拟南芥叶子中分离叶肉细胞,叶肉细胞的原生质体可以用来进行蛋白质活性瞬间表达和亚细胞定位分析。
