Team 10 - PETRY

Research Goal

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 PETRY team explores key parameters involved in tumor aggressiveness and relapse, in particular tumor metabolic adaptation and tumor microenvironment cooption.

Our research program is organized around three main axis :
1) The tumor plasticity by deciphering the dynamic evolution of multiple tumor cell states, including molecular subtypes, tumor-stem cells and metabolic heterogeneity
2) The vascular microenvironment and its impact on tumor agressivity and relapse, in particular following radiotherapy/chemotherapy
3) The development of innovative immunotherapeutic strategies through antibody and T-cell engineering

We have shown that GBM are characterized by diverses molecular, cellular and metabolic states, that evolve with time and treatments. We are interested in understanding this dynamic evolution of tumor cells, to subsequently exploit whereas preventing cell states transition or targeting tumor metabolic plasticity could be exploited to reduce GBM aggressiveness or to sensitize them to radio/chemotherapy. How radiation modulate cell state transition and metabolism are also key questions to answer before turning these potential vulnerabilities into therapeutic opportunity.

Vascular dysfunction plays a key role in the enhancement of RT-induced tumor regression and normal tissue toxicity after RT. We recently define that irradiated endothelial cells are developing a different acute and late secretome. We are willing to understand their similarity and difference in the modulation of RT efficacy. Final goal of this project is to facilitate the development of new therapeutic strategies targeting tumor microenvironment to prevent the resistance and recurrence of tumors after RT, which is a major challenge to prolong patient survival

Since 2008, our team focuses on immunotherapeutic strategies targeting the O-acetylated form of GD2 (OAcGD2). Being a carbohydrate antigen, OAcGD2 possesses identical biochemical structures between species, allowing antigen cross-reactivity and is a T cell-independent antigen, an interesting characteristic in poorly immunogenic tumors. We have shown that OAcGD2 is highly expressed on all NB tumors, but, contrary to GD2, is not found on peripheral nerves, pituitary gland and human brain. We have developed the 8B6 anti-OAcGD2 chimeric antibody which display immunological antitumor activity (ADCC and CDC) similar to GD2 mAb in vitro and in vivo. Our recent work has also shown that adoptive transfer of allogeneic Vγ9Vδ2 T lymphocytes might be considered as an efficient immunotherapy, at least in GBM). The final goal of these projects is to establish the proof-of-concept of targeted immunotherapies in preclinical models of GBM, NB and MB in combination with RT, essential for its translation to phase I/II clinical trials.
