Regulation of Protein Conformation Enables Cell‐Selective Targeting of Virus‐Mimicking Nanoparticles for siRNA Therapy of Glioblastoma

Abstract

Orthotopic glioblastoma (GBM) has an aggressive growth pattern and complex pathogenesis, becoming one of the most common and deadly tumors of the central nervous system (CNS). The emergence of RNA therapies offers promise for the treatment of GBM. However, the efficient and precise delivery of RNA drugs to specific tumor cells in the brain with high cellular heterogeneity remains ongoing. Here, we propose a strategy to regulate protein conformation through lipid nano‐environments (RPCLN) to custom‐design virus‐mimicking nanoparticles (VMNs) with excellent selective cell targeting capabilities, leading to efficient and precise delivery of small interfering RNA (siRNA) for effective treatment of GBM. The optimized VMNs not only retain the ability to cross the blood‐brain barrier (BBB) and release the RNA by lysosomal escape like natural viruses but also ensure precise enrichment in the GBM area. This study lays the conceptual foundation for the custom design of VMNs with superior cell‐selective targeting capabilities and opens up the possibility of RNA therapies for the efficient treatment of GBM and CNS tumors.This article is protected by copyright.
