High-grade glioma is the most aggressive form of brain cancer. Despite improvements in surgical procedures, chemotherapy, and radiotherapy, this type of brain tumour is still notoriously hard to treat: less than 10% of patients survive beyond five years. Researchers from KU Leuven, Belgium, have now shown that next-generation cell-based immunotherapy may offer new hope in the fight against brain cancer.
The researchers induced a specific type of cell death in brain cancer cells from mice. The dying cancer cells were then incubated together with dendritic cells, which play a vital role in the immune system. The researchers discovered that this type of cancer cell killing releases ‘danger signals’ that fully activate the dendritic cells. “We re-injected the activated dendritic cells into the mice as a therapeutic vaccine”, Professor Patrizia Agostinis explains. “That vaccine alerted the immune system to the presence of dangerous cancer cells in the body. As a result, the immune system could recognize them and start attacking the brain tumor.”
