Research overview

To address these limitations, we developed an engineered EV strategy integrating efficient miRNA packaging with tumor-targeting surface modifications to enhance therapeutic outcomes in melanoma. Ferroptosis induction was evaluated through lipid peroxidation analysis, mitochondrial membrane potential assays, and transmission electron microscopy (TEM).

Key findings

Rationale: Melanoma remains a highly aggressive malignancy with limited effective therapies and frequent resistance to immune checkpoint blockade (ICB).

Extracellular vesicles (EVs) represent a promising platform for RNA-based therapeutics, but their clinical translation is impeded by inefficient cargo loading and insufficient tumor-specific targeting.

To address these limitations, we developed an engineered EV strategy integrating efficient miRNA packaging with tumor-targeting surface modifications to enhance therapeutic outcomes in melanoma.

Methods: Engineered EVs (iEV-150) were generated by co-expressing miR-150-3p and Annexin A2 (ANXA2) in HEK293T cells, followed by surface modification with tumor-targeting iRGD peptides.
