Study Notes

Extracellular Vesicles (EVs)

The main function of extracellular vesicles (EVs) is to facilitate cell-to-cell communication and transfer of biological information.

Formation and Cargo

Exosomes are primarily formed in multivesicular bodies (MVBs) within cells.
Extracellular vesicles (EVs) can carry various types of cargo, including proteins, lipids, RNA, and DNA.

Distribution

Extracellular vesicles (EVs) are found in various bodily fluids, including blood, urine, saliva, and cerebrospinal fluid.

Classification

Extracellular vesicles (EVs) are classified based on their size, biogenesis, and release mechanisms into three main categories: exosomes, microvesicles, and apoptotic bodies.
