Native and engineered extracellular vesicles: novel tools for treating liver disease

Area of Science:

• Biomedical Engineering
• Regenerative Medicine
• Nanotechnology

Background:

• Liver diseases, including fibrosis, cirrhosis, and hepatoma, necessitate novel therapeutic strategies beyond liver transplantation.
• Extracellular vesicles (EVs) are natural nanocarriers facilitating cell-to-cell communication, crucial for immune regulation and tissue repair.
• Native EVs possess inherent biocompatibility and low immunogenicity, making them suitable candidates for liver disease treatment.

Purpose of the Study:

• To review the mechanisms and therapeutic effects of native EVs from various sources in treating diverse liver diseases.
• To summarize methods for enhancing EV liver targeting and cargo loading efficiency.
• To discuss engineered EVs, delivery strategies, and future challenges for clinical application.

Main Methods:

• Review of existing literature on extracellular vesicle applications in liver disease.
• Analysis of native EV mechanisms and therapeutic outcomes.
• Exploration of EV engineering techniques for improved targeting and efficacy.
• Discussion of delivery strategies and clinical translation hurdles.

Main Results:

• Native EVs demonstrate potential in treating various liver pathologies due to their biological properties.
• EV engineering offers avenues to optimize targeting, cargo delivery, and therapeutic impact.
• Advanced delivery strategies are being developed to enhance EV efficacy in liver disease models.

Conclusions:

• Extracellular vesicles represent a promising therapeutic modality for liver diseases.
• Further research into EV engineering and delivery is crucial for clinical translation.
