The lipidome remains a vast and poorly explored frontier that often goes awry in diseases like Parkinson's and Alzheimer's. We hope to gain genetic control over neural and glial lipidomes. How and why do select lipid species function in brain cells, including in synaptic vesicle fusion, lysosome catabolism, or glial ensheathment? We are excited to develop genetic tools to cell-type specifically track and manipulate the lipidome using the Drosophila brain as a tractable model.
