Application of engineered exosomes in tumor therapy

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Oncology

Background:

• Malignant tumors represent a major global health challenge.
• Conventional cancer therapies often lack specificity, causing significant side effects.
• Exosomes, as natural intercellular communicators, possess inherent biocompatibility and low toxicity.

Purpose of the Study:

• To review engineered exosomes as targeted delivery vehicles for cancer therapy.
• To summarize exosome engineering strategies and applications.
• To identify challenges in clinical translation of exosome-based therapies.

Main Methods:

• Review of literature on exosome biogenesis and engineering.
• Analysis of exosome modification techniques for drug delivery.
• Discussion of exosome-based therapeutic strategies in preclinical and clinical studies.

Main Results:

• Engineered exosomes can be tailored for enhanced tumor targeting and drug delivery.
• Various methods exist for exosome production, modification, and drug loading.
• Exosomes demonstrate potential in overcoming drug resistance and reducing systemic toxicity.

Conclusions:

• Engineered exosomes hold significant promise for advancing targeted cancer treatment.
• Further research is needed to address challenges in large-scale production and clinical implementation.
• Exosome engineering offers a novel platform for developing next-generation cancer therapeutics.
