Fungal infections pose a threat to humans, animals and plants, with in part serious consequences. Together with colleagues from Frankfurt/Main and Aachen, a research team from Heinrich Heine University Düsseldorf (HHU) has now clarified an important mechanism in how such infections are regulated at molecular level. In the scientific journal Proceedings of the National Academy of Sciences (PNAS), they describe how this discovery may lead to the development of new antifungal agents.
