Recent progress in exosome research: isolation, characterization and clinical applications

Area of Science:

• Biochemistry
• Cell Biology
• Oncology

Background:

• Exosomes are nano-vesicles released by cells, transporting proteins, RNAs, DNAs, and lipids.
• Exosomes mediate intercellular communication and play significant roles in cancer development.
• Differential cargo expression in exosomes from biological fluids suggests potential for cancer diagnostics.

Purpose of the Study:

• To review recent advancements in exosome isolation and characterization techniques.
• To explore the biological functions of exosomes in cancer progression, including metastasis, drug resistance, and immune regulation.
• To outline the therapeutic applications of exosomes in cancer treatment.

Main Methods:

• Literature review of recent progress in exosome isolation and characterization.
• Analysis of studies on exosome biological functions in cancer.
• Compilation of research on exosome-based cancer therapies.

Main Results:

• Exosomes are involved in intercellular communication and cancer development.
• Exosome cargo analysis shows potential for liquid biopsy in cancer diagnosis and prognosis.
• Exosomes exhibit favorable biocompatibility, safety, and low immunogenicity for therapeutic applications.

Conclusions:

• Exosomes are crucial in cancer biology, influencing metastasis, drug resistance, and immune responses.
• Exosomes hold significant promise as biomarkers for minimally invasive cancer diagnostics (liquid biopsy).
• Exosomes offer potential as biocompatible and safe therapeutic agents for cancer treatment.
