Dr. Reynaud’s long-standing research interest is to understand the mechanisms controlling cell fate decisions in the hematopoietic system. During his graduate and post-graduate training, he worked to decipher the transcriptional regulatory networks that (i) control self-renewal activity and lineage specification in hematopoietic stem cells and (ii) regulate progenitor differentiation during the establishment of the natural and adaptive immune system. More recently he investigated the deregulation in stem and progenitor cell activity that, in adults, leads to the development of abnormal hematopoiesis and eventually to chronic myeloid leukemia. This work uncovered an unexpected contribution of the pro-inflammatory environment to leukemia development. Notably he identified a novel function for the pro-inflammatory cytokine IL-6 in reprogramming the fate of an early leukemic progenitor by promoting myeloid development at the expense of lymphoid differentiation. Following this work, the overall goal of his research at Cincinnati Children’s Hospital Medical Center is to characterize how micro-environmental signals regulate normal B lymphoid and how corruption of these signals contribute to the initiation, maintenance and progression of acute lymphoblastic leukemia.
