[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 pathogenicity such as ∆gcsA and ∆sdeA (Fernandes et al., 2016). [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]  Embryogenic suspension cultures of Araucaria angustifolia (Bertol.) Kuntze (Araucariaceae) can be used as a model to test the effects of compounds added to the culture medium on the cellular growth and morphology of Pro-Embryogenic Masses (PEMs). PEMs are formed by embryogenic and suspensor-type cells. To measure changes in the cellular growth of embryogenic cultures, we performed sedimented cell volume (SCV) quantification, which is a non-destructive method. Morphological analysis by microscopy allowed for the observation of growth and development of PEMs and the alterations in embryogenic and suspensor-type cells. The methods used here provide an efficient means for monitoring the cellular growth of PEMs and identifying morphological changes during the development of ... [摘要]  可以使用南洋杉(Araucaria angustifolia)(Bertol。)Kuntze(Araucariaceae)的胚胎悬浮培养物作为模型来测试添加到培养基中的化合物对前胚胎形成质量的细胞生长和形态的影响PEM)。 PEM由胚胎形成和悬浮细胞形成。为了测量胚胎发生培养物的细胞生长的变化,我们进行沉降细胞体积(SCV)定量,其是非破坏性方法。通过显微镜进行的形态学分析允许观察PEM的生长和发育以及胚胎形成和悬浮体型细胞的改变。这里使用的方法提供了一个有效的手段监测PEM的细胞生长和识别胚胎发育培养发展过程中的形态变化。这些研究还可以与生物化学和分子分析例如蛋白质组学结合,以进一步研究胚胎生长和形态。
