Core Tip

Core Tip: Extracellular vesicles (EVs), especially small EVs (sEVs) derived from liver cells, have been the focus of much attention in the normal physiology and pathogenesis of various diseases affecting the liver. sEVs are approximately 100 nm in size, enclosed within lipid bilayers, and are very stable. The proteins and nucleic acids, including miRNAs, contained within these vesicles are known to play important roles in intercellular communication. This mini-review summarizes the application of sEVs in the diagnosis of liver diseases, along with their distribution post administration, their role in pathogenesis, and their potential therapeutic effects in hepatic disorders.
