Molecular Pharmacology of Lysophospholipid Mediators


Our research program seeks to increase understanding of the biology and pathobiology of the lysophospholipid mediator, sphingosine 1-phosphate (S1P). We use primarily chemical biology approaches and secondarily mutant mouse models in our research. We are particularly focused on developing drug-like molecules to rigorously test the hypothesis that interdiction of S1P signaling at the level of synthesis is a viable therapeutic strategy. Other areas of interest include the mechanism of uptake of sphingoid bases by cells, the routes of S1P metabolism and the function of putative mitochondrial lipid kinase.
