Systemic mRNA aggregates elicit immunologic reprogramming that unlocks anti-cancer immunity

Hum Vaccin Immunother. 2025 Dec;21(1):2543599. doi: 10.1080/21645515.2025.2543599. Epub 2025 Aug 19.

Abstract

Successful cancer immunotherapy requires novel approaches that overcome intratumoral immunosuppression and peripheral tolerance. In a recent manuscript describing intravenously administered mRNA-loaded lipid particle aggregates (RNA-LPAs), we demonstrate the ability to reprogram both the tumor microenvironment and periphery enabling cancer-specific immunity simultaneously generated to compete against immunologically 'cold' malignancies like glioblastoma.

Keywords: cancer; immunotherapy; mRNA vaccines.
