Echinocandin Resistance

Antifungal resistance in pathogenic fungi is a growing global health concern. Non-pathogenic Saccharomyces cerevisiae is a useful model for studying mechanisms of antifungal resistance that are relevant to understanding the same processes in pathogenic fungi. yEvo high school students used experimental evolution to study antifungal resistance by growing yeast in increasing concentrations of different types of antifungal drugs: azoles and echinocandins.

Echinocandins are a group of medical drugs used to kill disease-causing fungi. Echinocandins kill fungi by blocking enzymes that are needed to make and maintain the cell wall. But, like bacteria can develop antibiotic resistance, fungi can develop resistance to antifungal drugs. In this project, the specific echinocandin drugs caspofungin and micafungin will be used to understand how fungi can become resistant to this drug. By understanding how resistance occurs, we can create possible solutions for treating echinocandin-resistant fungal infections.

Results

Our research on echinocandin resistance is ongoing, but you can view some of the mutations we have found so far on the yEvo mutation browser!
