Extracellular microRNAs (ex-miRNAs) participate in intercellular communication. Secreted miRNAs are transported by extracellular vesicles (EVs) and transferred to recipient cells, where they regulate posttranscriptional gene expression. Different types of EVs exist. Membrane-derived exosomes are released from cells as endosomes containing multivesicular bodies (MVB) that fuse with the plasma membrane. Microvesicles (MVs) are released from the plasma membrane via outward budding. Multivesicular cargo (MVC) is released by membrane budding during apocrine secretion. Extracellular vesicles and their miRNA cargo are transferred to recipient cells after endocytosis or membrane fusion.
