Summary
Exosomes, or bioactive vesicles, facilitate intercellular communication and play roles in disease. This review explores exosome biogenesis, function, and potential as biomarkers and vaccine candidates.
Area of Science:
- Cell Biology
- Immunology
- Biochemistry
Background:
- Exosomes are bioactive vesicles mediating intercellular communication.
- Their biogenesis involves multivesicular bodies fusing with the plasma membrane.
- Exosomes are released by various cell types, but their precise functions are still under investigation.
Purpose of the Study:
- To review exosome biogenesis and composition.
- To focus on novel insights into exosome functions.
- To discuss the potential of exosomes as disease biomarkers and vaccine candidates.
Main Methods:
- Literature review of recent studies on exosomes.
- Analysis of exosome biogenesis and release mechanisms.
- Examination of exosome roles in intercellular communication, disease, and immunity.
Main Results:
- Exosomes are implicated in intercellular communication and can spread infectious agents.
- Exosomes from infected cells contain microbial components, aiding antigen presentation and macrophage activation.
- Exosomes may be involved in immune surveillance.
Conclusions:
- Exosomes have diverse functions beyond tumor antigen presentation.
- Exosomes show promise as diagnostic biomarkers for various diseases.
- Exosomes represent potential candidates for novel vaccine development.

Overview of Exosomes
Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.

Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
The Tumor Microenvironment
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
