We all breathe into our lungs thousands of fungal spores every single day and among them we encounter Aspergillus fumigatus spores. Fortunately our immune system is extremely good at killing these spores. However, if the individual’s immune system is not working properly Aspergillus fumigatus can survive and become life-threatening.
Unfortunately there are few anti-fungal drugs available to treat this killing machine and understanding of how they work is a limited.
Using advanced time-lapse microscopy I have been studying the main cellular adaptations that allows Aspergillus fumigatus to overcome the attack of caspofungin, a commonly used anti-fungal drug.
My research will provide a better understanding of the way in which caspofungin works in inhibiting Aspergillus fumigatus growth and infection. And this might provide new insights into how the design of novel anti-fungal drugs might be improved.
