The present invention relates to a nucleic acid comprising a gene encoding a luciferase, which is under the control of a promoter for expression of said luciferase in a filamentous fungal host cell, such as an Aspergillus fumigatus host cell. Advantageously, the promoter is the glyceraldehyde-3-phosphate dehydrogenase promoter from Aspergillus fumigatus. The invention further relates to a transformed filamentous fungal host cell comprising the nucleic acid of the invention, and to an animal model using different immunosuppression regimens which has been infected with said filamentous fungal host cell. The invention also relates to methods for determining the virulence of filamentous fungal host cells, for studying a fungal infection, or for determining the antifungal activity of a compound.
本发明涉及一种包含编码荧光素酶基因的核酸,该基因受启动子控制,用于在丝状真菌宿主细胞(如烟曲霉宿主细胞)中表达所述荧光素酶。有利的是,启动子是来自烟曲霉的甘油醛-3-磷酸脱氢酶启动子。本发明进一步涉及包含本发明核酸的转化丝状真菌宿主细胞,以及感染了所述丝状真菌宿主细胞的使用不同免疫抑制方案的动物模型。本发明还涉及确定丝状真菌宿主细胞毒力、研究真菌感染或确定化合物抗真菌活性的方法。
