Glioblastoma is the most common and most aggressive form of brain cancer. As the 3rd cause of cancer-related death in young adults (aged between 15 and 35 years), this incurable tumour is associated with very limited survival.
Following diagnosis, very few patients (5%) survive for more than 3 years, and half of them are carried off by the disease within a year of diagnosis.
This tumour strikes sporadically, with no known risk factors associated with the disease in most cases. Although the molecular causes of the emergence of glioblastoma are not (yet) determined, it could be the result of mutations occurring in so-called stem cells giving rise to neurons and glial cells.
The Strasbourg-based teams are very interested in tumour-producing stem cells, and in particular in the role of the CXCL12/CXCR4/ACKR3 pathway in controlling how these cells functiiton. Our researchers have developed a family of molecules neutralising the chemokine CXCL12, a small protein that is known to be responsible for cellular migration, and are studying their effect on self-renewal of tumour-producing stem cells. Thanks to these studies, the researchers hope to open up innovative therapeutic perspectives in cancer treatment.
