GSCs in the Transdifferentiation Phenomenon: Focus on CAR-T-Based Therapy

Le résumé fourni par la source

Glioblastoma (GBM) remains one of the most lethal brain tumors, largely due to the resilience and plasticity of glioblastoma stem cells (GSCs), which drive tumor growth, recurrence, and resistance to conventional therapies. A key mechanism underlying their aggressiveness is transdifferentiation, whereby GSCs acquire endothelial- and pericyte-like phenotypes, promoting neovascularization and remodeling the tumor microenvironment to sustain malignancy. Conventional treatments often fail to eliminate these resilient populations, highlighting the need for innovative targeted strategies. Chimeric antigen receptor (CAR)-based immunotherapies offer a targeted strategy to specifically eliminate GSCs and interfere with their role in promoting tumor vascularization and suppressing immune responses. This review aims to provide a comprehensive overview of the molecular mechanisms driving GSC transdifferentiation and to summarize the current landscape of CAR-T therapies developed to target these cells. By integrating knowledge of GSC biology with advances in CAR-T-based interventions, this work highlights the potential of next-generation immunotherapies to overcome therapeutic resistance, limit tumor recurrence, and improve clinical outcomes in GBM.
