Exosomes: A Brief Review of Biology and Medical Applications

Extracellular vesicles (EV) are subcellular components derived from a cell that are essential mediators of intercellular communication. Exosomes are a type of extracellular vesicle secreted by the cell. Exosomes have immense therapeutic significance and benefits in a variety of medical applications, including medication nanodelivery, cell and gene therapy, immunological response, biomarker therapy, and anticancer vaccination. Methods for isolating exosomes, including ultracentrifugation, size-based isolation, immune-affinity capture-based approaches, precipitation, and microfluidic methods, are described in this brief review. Additionally, studies that demonstrate the diverse potential of exosomes as agents in diagnosis and natural agent therapeutics are briefly discussed. The potential of exosomes extends to anticancer vaccines, with evidence supporting their role in inducing potent antitumor immune responses. Despite advancements, further research is needed to unlock the full diagnostic and therapeutic capabilities of exosomes. In summary, this concise review highlights the multifaceted nature of exosomes, showcasing their crucial role in intercellular communication and their diverse applications in biomedicine.
