IL-4 and immuno-modulation are hallmarks of parasitic infections, my laboratory broadly focuses on using the helminth parasite Schistosoma mansoni as a tool to understand both, the consequences of IL-4 induced immuno-modulation, and the complex interplay between B, T and stromal cells necessary to develop an optimal T and B cell memory response Under this umbrella we currently have three main projects:
- Understanding the immunological implications of maternal schistosomiasis;
- Dissecting the role of IL-4 in shaping the cellular environment of peripheral lymph nodes during homeostasis and antigenic challenge;
- Delineating the mechanistic role of hepatic macrophages in helminth-induced protection from metabolic diseases.
