Summary
Lipid nanoparticles (LNPs) are key for mRNA therapies, but escaping the endo-lysosome system is crucial for success. Molecular engineering of LNPs improves mRNA delivery and protein expression for cancer treatment.
Area of Science:
- Biotechnology
- Molecular Biology
- Oncology
Background:
- Messenger RNA (mRNA)-based therapeutics offer revolutionary potential for cancer immunotherapy, gene restoration, and editing.
- Efficient delivery systems are critical for mRNA stability and cytoplasmic translation.
- Lipid nanoparticles (LNPs) are advanced platforms, yet endo/lysosomal escape remains a significant hurdle.
Purpose of the Study:
- To review the intracellular journey of mRNA-loaded LNPs, focusing on endo/lysosomal processing.
- To explore strategies for enhancing LNP-mediated endo/lysosomal escape.
- To provide insights for advancing mRNA-based cancer therapies through improved protein expression.
Main Methods:
- Summarizing the internalization pathways and endo-lysosomal processing of mRNA-loaded LNPs.
- Discussing the impact of endo-lysosomal processes on mRNA delivery efficiency.
- Reviewing molecular engineering strategies for LNP lipid composition (ionizable lipids, helper lipids, cholesterol, PEGylated lipids).
- Examining ancillary strategies like surface coating and shape management.
Main Results:
- Endo/lysosomal escape is a critical bottleneck for LNP-mediated mRNA delivery.
- Optimizing LNP lipid composition and surface properties can enhance endo/lysosomal escape.
- Molecular engineering offers promising avenues to improve LNP performance.
Conclusions:

Site-targeted drug delivery systems enhance therapeutic efficacy while minimizing systemic toxicity and treatment costs. Unlike conventional methods, these systems ensure precise drug delivery, improving bioavailability and reducing side effects. Targeted drug delivery is classified into three levels. First-order targeting directs drugs to the capillary beds of specific organs or tissues. Second-order targets specific cell types, such as tumor cells, using receptor-mediated interactions.

Polymeric carriers enhance targeted drug delivery by increasing efficacy while minimizing off-target effects. These carriers comprise a biodegradable polymeric backbone integrated with functional elements that enable targeting, improve physicochemical properties, and regulate drug release.Targeting MechanismsThe targeting ability of polymeric carriers is mediated by a homing device, which is a molecular recognition component designed to selectively bind to specific tissues or cells.
