Extracellular vesicles (EVs) are tiny structures released by cells that play a significant role in intercellular communication. Also known as exosomes, they are like small packages or "bubbles" that contain various molecules such as proteins, lipids, and nucleic acids. These vesicles are released from cells into the surrounding extracellular space and can be found in bodily fluids like blood, urine, and saliva. EVs serve as vehicles for transferring information between cells, allowing cells to communicate and influence each other's behavior. They can transport important signals, such as genetic material or signaling molecules, to target cells, impacting various biological processes like immune response, tissue repair, and disease progression.
