Microparticles: Modulators and biomarkers of liver disease
2012
Division of Molecular and Translational Medicine,Dept. of Medicine I, Johannes Gutenberg University, Mainz, GermanyEmerging role of microparticlesMicroparticles (MP) have gained increasing attention as biomark-ers for various diseases. First described as platelet dust, MP wereregarded as unspecific debris [1]. However, it has become appar-ent that cell derived MP or ectosomes represent a novel route ofhorizontal communication between cells. MP are between 100–1000 nm in size and generated through cell membrane shedding(ectocytosis), a process that can be triggered by the activation ofthe complement C5b-9 complex, as shown for platelet derivedMP, or by inhibition of flippase activitythroughCa
