The main focus of Professor Aifantis' laboratory is the study of the mechanisms of hematopoietic stem cell (HSC) differentiation and transformation. The research is focused on three signaling pathways:  Notch, Hedgehog (Hh) and SCF ubiquitin ligase signaling cascades, and their role in stem cell biology and function. Notch is a receptor/transcription factor initially identified in Drosophila melanogaster that is remarkably conserved during evolution. The studies have found that Notch not only affects stem cell commitment to the T lymphocyte lineage, but also transform the cells to induce fatal T cell acute lymphoblastic leukemia (T-ALL). Aifantis is studying the signaling pathways responsible for the oncogenic transformation of stem cells to identify cancer-initiating stem cells in T-ALL. Dr. Aifantis is using both loss and gain of function animal models to study the role of Hh signaling in HSC differentiation and self-renewal.
