In recent years, there has been exponential growth in the interest in microvesicles, which is reflected by the number of publications. Initially referred to as "platelet dust" by Peter Wolf in 1967, platelet microvesicles (PMV) are now recognized as important mediators of intercellular communication. There are examples of PMV exerting physiological effects on almost all hematological and vascular cell types, including monocytes, macrophages, neutrophils, T-cells, endothelium cells, and smooth muscle cells (SMCs). PMV can exert these effects by multiple methods: extracellular signaling through receptors, transfer of surface molecules, and delivery of intracellular contents including miRNA. Recent work suggests a complex environment in which cellular contents are being shared multi-directionally between multiple cell types. This review will focus on the communicative properties of PMV.
