Microvesicle
Microvesicle (pronunciation: /ˈmaɪkrəʊˌvɛsɪkəl/) is a term used in cell biology to describe a type of extracellular vesicle.
Etymology
The term "microvesicle" is derived from the Greek words "micros" meaning small, and "vesicula" meaning little bladder.
Definition
A Microvesicle is a small structure within a cell, consisting of fluid enclosed by a lipid bilayer. Microvesicles are a type of extracellular vesicle that are released from the cell during cell activation or apoptosis. They range in size from 100-1000 nanometers in diameter and contain various types of molecules including proteins, lipids, and nucleic acids.
Function
Microvesicles play a crucial role in cell-to-cell communication, allowing cells to exchange proteins, lipids, and genetic material. They are involved in a variety of biological processes, including immune responses, angiogenesis, and coagulation. In addition, they have been implicated in the pathogenesis of several diseases, including cancer and cardiovascular disease.
