    Team: Cancer and Immune Response


    Team leader



    The team in brief… Our team investigates the mechanisms whereby T cells trigger an immune response in physiological and pathological conditions including in cancers. We are particularly interested in the capacity of T cells to migrate and to recognize a foreign antigen. To address these issues, we make an extensive use of dynamic imaging microscopy.



    Research conducted in our team is centered in studying T cell activation and migration with approaches ranging from molecular and cellular levels to more integrated systems. For this purpose, we have developed new tools based on fluorescence microscopy that has always been important in our experimental approaches. Precisely, we intend to understand the early signaling events and the molecular partners underlying T cell migration and activation.  We are also interested in defining the role played by the PI3K/FoxO pathway in T cell homeostasis and differentiation. The characterization of new FoxO targets represents an important aspect of our work too. Over the last years, we have taken advantage of our experience with T cells in vitro to address questions related to the behavior of these cells in ex-vivo conditions in normal lymphoid tissues and tumors, with a particular focusing on mechanisms by which human tumors escape T cell attacks. More recently, we have initiated a new project that aims to identify the cross-talk between the immune system and the nervous system during cancer development. Finally, we are exploring, in time and space, how a successful immune response triggered by various immunotherapy protocols leads to tumor regression.
