Chemogenomics

Candida albicans is the leading cause of fungal infections in humans. Despite available therapy options mortality rates reach up to 50%, a rate that highlights the shortcomings of current therapy strategies. Developing new antifungal strategies, therefore, remains a pressing need.

Our initial hypothesis towards improved fungal drug treatment relied on combination antifungal therapy, where two agents combined would be significantly more efficacious compared to either agent alone. In two proof-of-concept studies, we have firmly established this approach [1,2].

We have been following up on this work. In a systems biologically-driven approach, we are combining HTS, virtual as well as chemogenomic screening strategies to explore new drug targets and identify additional drugs that can be combined with existing drugs to improve clinical therapies. Our chemogenomic screening has identified new genetic interactions with a variety of antifungal drugs.
