The classical therapeutic scheme for neural cancers, such as Glioblastoma and Neuroblastoma, involved surgery followed with a combination of radio- and chemotherapies. However tumor location and acquired treatment resistance limit the efficacy of these treatments. Novel non-genotoxic therapeutic approaches in combination with actual treatments are currently being explored to improve their efficacy.

On this basis, the PETRI team explores 2 key parameters involved in tumor aggressiveness and relapse, tumoral metabolic adaptation and tumoral microenvironment cooption.
Our research program is organized around four main axis :
1)Impact of microvascular dysfunctions in tumor response to radiotherapy and relapse
2) Reciprocal impact of metabolic adaptation, microenvironment, and radiotherapy in the tumor ecosystem
3) Development of innovative immunotherapeutic strategies through antibody and T-cell engineering
4) Improvement of radiotherapy efficacy through innovative immunotherapeutic approaches
