Areas of Research: Our major goal is to understand how immune cells (T, B and mononuclear cells) differentiate into protective long-lasting effector cells to develop novel immune-based therapies against microbial pathogens and tumors.

Professional Interests

Immune effector cell differentiation & protective host responses against microbial pathogens and tumors in vivo

Microbial pathogens invasion usually triggers potent host immune responses, however efficient protection and pathogen killing require the presence of effector cells and combinations of inflammatory signals that are ill-defined in most infections and during cancers.

Our work therefore focuses on precisely defining these events using mouse models and when possible patient samples. Specifically, we investigate (i) the inflammatory signals and related pathways, and innate immune cells that regulate CD8 T cell differentiation, and (ii) the cross-talks between memory T cells and innate immune cells during infections as well as tumor progression and (iii) the protective immune response against malaria. Immune cells we focus on include monocytes, macrophages, dendritic cells and T and B lymphocytes. We use various models of infections in mice, namely the bacteria Listeria monocytogenes, the Vesicular Stomatitis virus and Murine Cytomegalovirus and various murine Plasmodium parasites. We take advantage of a range of advanced fluorescent-tracer based methodologies to monitor immune cells in situ. We conduct cell transfer experiments and take advantage of novel genetically modified mouse models in which dynamic cell functions can be monitored and/or in which functional subsets of immune cells can be selectively eliminated.

Overall, the goal of my laboratory is to improve our fine understanding of the factors that orchestrate antimicrobial and antitumoral host protective immune responses in vivo. We believe that our work will contribute to better immune cell-mediated preventive and therapeutic strategies.
