exosomes

Exosomes are tiny, membrane-bound particles released by cells into the body. Think of them as small message carriers—containing proteins, lipids, and genetic material—that help cells communicate with each other. These vesicles play roles in normal bodily functions like immune response and tissue repair, as well as in disease processes such as cancer. Because they carry information from their originating cells, exosomes are also being studied as potential tools for diagnostics and therapies, offering insights into health and disease through their molecular contents.
