Abstract

Glioblastoma multiforme (GBM) is a complex and aggressive central nervous system (CNS) tumor that has a poor prognosis, and restricted therapeutic options are available despite the increasing research conducted. Moreover, the cells in our body package microRNAs, ubiquitous modulators of numerous biological processes, into exosomes for cell-to-cell signaling. Indeed, exosomal miRNAs contribute to several aspects of glioma, such as development, occurrence, metastasis, and immune evasion. Additionally, exosomal miRNAs play a key role in cellular functions and glioma pathogenesis by regulating numerous pathways, including the Wnt/β-catenin, PTEN/PI3K/Akt, EGFR/MAPK, notch signaling, and NF-κB. Notably, exosomal miRNAs are recognized to have promising potential in clinical applications; in fact, exosomal miRNAs are emerging biomarkers for glioma diagnosis and prognosis and are additionally considered as putative therapeutic candidates by inhibiting tumor progression, occurrence, and metastasis. This review presents the current knowledge regarding clinical potential and application of exosomal miRNAs in glioma, as well as the miRNA-mediated regulatory network underlying glioma immunopathogenesis. © 2025 Elsevier B.V., All rights reserved.
