Team presentation
The laboratory aims to understand genetic alterations and changes in the tumor microenvironment during the evolution of brain tumors, and to determine how these alterations influence tumor behavior and their response to treatments, with the goal of improving therapeutic strategies. To achieve this, the laboratory uses patient samples obtained from surgery as well as numerous preclinical in vitro and in vivo models.
Our research focuses on three main areas
- Improving the understanding of tumor heterogeneity in order to better predict patient prognosis and treatment response
- Identifying and targeting the mechanisms underlying treatment resistance in brain tumors
- Modulating interactions between tumor cells and the microenvironment to optimize new treatments, particularly immunotherapy
Some of the team’s flagship projects
- Integrated study of brain tumors heterogeneity (glioblastomas, IDH-mutant gliomas, primary central nervous system lymphomas, and rare tumors), combining multi-omics analyses (genetic, epigenetic, transcriptomic, histomic), exploration of interactions with the tumor microenvironment, and development of innovative tools in advanced imaging and artificial intelligence (Leaders: Agusti Alentorn, Franck Bielle, Francesca Branzoli, Khê Hoang-Xuan)
- Characterization of resistance mechanisms to chemotherapy and immunotherapy and development of new therapeutic strategies, particularly in glioblastoma, aimed at improving patient prognosis, using models such as patient-derived cell lines, xenografts, tumoroids, and organoids (Leaders: Ahmed Idbaih, Isabelle Le Roux, Mehdi Touat, Maïté Verreault)
- Study of interactions between tumor cells and their microenvironment, particularly myeloid and lymphoid cells and the vascular network, in order to identify predictive biomarkers of response and characterize therapeutic synergies (Leaders: Luis J. Castro-Vega, Ahmed Idbaih, Isabelle Le Roux, Michel Mallat, Marc Sanson, Mehdi Touat)
