Research Interests
Our research relies primarily on the use of Drosophila, a genetically amenable model system, to elucidate the previously unexplored role of peroxisomes as signaling platforms in the innate immune response. We demonstrated the peroxisome direct involvement in immune defense, with evidence of peroxisome requirements in phagocytic pathogen clearance and innate immune signaling in immune responsive tissue in flies and mammals. Peroxisomes are essential metabolic organelles present in every eukaryotic cell.
Our research program aims to define peroxisome-specific requirements during immune challenge. Specifically, we want to dissect how peroxisomes regulate innate immune signals produced by macrophages and gut cells upon infection. We focus on the role that peroxisomes and peroxisome metabolic products (lipids and reactive species) play in the Drosophila Toll and IMD immune defense pathways (orthologous to the human Toll and TNF innate immune pathways) for the resolution of infection. Defining the roles of peroxisomes in these processes has implications for our understanding of peroxisome metabolic signaling in inflammation, immunodeficiency, cancer and diabetes and opens a new unexplored field of the innate immunity.
