摘要

Glioblastoma (GBM) leverages exosomes to drive tumor progression, immunosuppression, and therapy resistance through transfer of oncogenic miRNAs, circRNAs, and proteins. These vesicles reprogram the tumor microenvironment (TME) by activating pathways such as TREM1 in microglia and STAT3-mediated vasculogenic mimicry. Exosomal nucleic acids, including circZNF800 and miR-374b-3p, serve as non-invasive biomarkers for recurrence and treatment monitoring. Advances in engineering, such as Angiopep-2-functionalized exosomes for blood-brain barrier penetration and CRISPR-Cas9-loaded vesicles targeting resistance genes, highlight their therapeutic potential. Challenges in heterogeneity, standardization, and scalable production underscore the need for interdisciplinary innovation to translate exosome-based strategies into clinical practice.
