The aim of my research is to find novel drug therapies for neurodegenerative diseases, such as Alzheimer’s and Parkinson’s diseases, that don’t currently have curative treatment. Our long-term research topic has been PREP enzyme and targeting on it with small-molecular compounds, and we have shown that by targeting PREP we can block several toxic features in models of neurodegenerative diseases. Moreover, based on our PREP research we have found similar multitargeting drug targets, and are currently opening novel research lines.
