[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] The inflammatory response is essential to the reestablishment of cutaneous homeostasis following injury. In this context, leukocytes arrive at the wound site and orchestrate essential events in the wound healing process. Therefore, the quantification of specific subsets of inflammatory cells in the wound tissue is of considerable interest. The current protocol focus on a quantitative index of neutrophils and macrophages accumulation within skin lesions by measuring the specific activity of the marker enzymes Myeloperoxidase (MPO) and N-acetyl-β-D-glucosaminidase (NAG), respectively. MPO is present in high levels in the azurophilic granules of neutrophils and NAG in lysosomes of activated macrophages. These methods allow the indirect estimation of the abundance of neutrophils and ...
[摘要] 炎症反应对于损伤后皮肤稳态的再建立是必需的。 在这种情况下，白细胞到达伤口部位并协调伤口愈合过程中的重要事件。 因此，对伤口组织中炎性细胞的特定亚群的定量是相当感兴趣的。 通过测量标记酶髓过氧化物酶（MPO）和N-乙酰基-β-D-氨基葡萄糖苷酶（NAG）的比活性，目前的方案集中于皮肤损伤中嗜中性粒细胞和巨噬细胞积累的定量指数。 MPO以高水平存在于嗜中性粒细胞和NAG的嗜苯胺粒细胞中，在激活的巨噬细胞的溶酶体中。 这些方法允许间接估计积累到皮肤中的嗜中性粒细胞和巨噬细胞的丰度。
