Extracellular vesicles are small membrane-bound particles released by cells into the extracellular environment. They contain a variety of molecules, including proteins, lipids, and nucleic acids, which can serve as signaling molecules or carriers of cargo between cells. Research in this area focuses on understanding the biology and functions of extracellular vesicles, as well as their potential roles in health and disease. This includes studies on their biogenesis, composition, and mechanisms of intercellular communication. Extracellular vesicles have been implicated in a wide range of physiological processes, such as immune responses, cell-to-cell communication, and tissue regeneration, and their dysregulation has been associated with various diseases, including cancer, neurodegenerative disorders, and cardiovascular diseases. Studies in extracellular vesicles have the potential to provide insights into new biomarkers and therapeutic targets for various medical conditions.
