Immunobiology of Mononuclear Phagocytes
The Lawrence lab studies macrophages and dendritic cells and their roles in cancer. We use sophisticated genetic mouse models and high dimensional proteomic and genomic analysis at single cell and spatial resolution to understand the roles these cells play in shaping the tumor microenvironment and it's impact on tumor growth and response to therapy. Our previous work has identified macrophage and dendritic cell subsets with pro and anti-tumoral functions and we have mapped molecular pathways that drive their functional polarization within the tumor microenvironment. We continue to dissect the molecular pathways and cellular mechanisms that drive the functional diversification of these cells with the aim to identify targets for therapeutic intervention.

Hematopoiesis and Inflammation
The HSC group joined the Lawrence lab in January 2024, we focus on hematopoietic stem cells and macrophages. The work carried out by Sandrine Sarrazin and Bérengère De Laval explores how hematopoietic stem cells commit to the myeloid lineage, sense pathogens, and establish immune memory, uncovering previously unknown functions in immune responses. Simultaneously, the group explores self-renewal and reprogramming processes in macrophages, examining their roles in inflammation, tissue regeneration, and cancer. This research aims to deepen our understanding of the connections between hematopoietic development,
