The sulfur-related metabolic status of during infection reveals cytosolic serine hydroxymethyltransferase as a promising antifungal target.

Sulfur metabolism is an essential aspect of fungal physiology and pathogenicity. Fungal sulfur metabolism comprises anabolic and catabolic routes that are not well conserved in mammals, therefore is considered a promising source of prospective novel antifungal targets. To gain insight into sulfur-related metabolism during infection, we used a NanoString custom nCounter-TagSet and compared the expression of 68 key metabolic genes in different murine models of invasive pulmonary aspergillosis, at 3 time-points, and under a variety of conditions.

Shining a light on the impact of antifungals on subcellular dynamics through fluorescence imaging.

Fluorescent proteins (FPs) are indispensable tools used for molecular imaging, single-cell dynamics, imaging in infection models, and more. However, next-generation FPs have yet to be characterized in . Here, we characterize 18 FPs in the pathogenic filamentous fungus spanning the visible light spectrum.

Aspergillus fumigatus strains that evolve resistance to the agrochemical fungicide ipflufenoquin in vitro are also resistant to olorofim.

Widespread use of azole antifungals in agriculture has been linked to resistance in the pathogenic fungus Aspergillus fumigatus. We show that exposure of A. fumigatus to the agrochemical fungicide, ipflufenoquin, in vitro can select for strains that are resistant to olorofim, a first-in-class clinical antifungal with the same mechanism of action.
