Research focus

The amazing ability of the immune system to recognize and modulate atypical micro-environments (tumor, inflammation) makes it the perfect weapon to fight cancer. However the high complexity of molecular pathways and cell populations involved in mounting the anti-tumor response makes the immunotherapies ineffective in a high percentage of patients. Expanding its benefits possibly goes through the development of combined therapies which systemic application that are frequently related to severe collateral effects.
My current research focus on the use of mRNA gene transfer to induce an intratumoral production of immunomodulatory molecules that can eventually trigger a strong anti-tumor response and avoid the collateral effects of systemic therapies. We are evaluating the synergy between intratumoral PD-L1 blockade and tumor antigen vaccination.
