Zusammenfassung

Mikropartikel (MP) sind kleine Zellvesikel, die von Zellen im Rahmen von Aktivierung oder Apoptose freigesetzt werden und im Blut nachweisbar sind. MP bestehen aus Plasma und Zellmembran ihrer Ursprungszelle und können anhand ihrer Oberflächenantigene ihrer Ursprungszelle zugeordnet werden. Durch den Nachweis entsprechender MP kann somit eine Aussage über den Funktionszustand der Ursprungszelle (Aktivierung oder Apoptose) getroffen werden. Mittlerweile ist bekannt, dass MP als Vektoren spezifische biologische Informationen zwischen einzelnen Zellen austauschen können und somit ein wesentliches Bindeglied in der Pathophysiologie inflammatorischer und koagulatorischer Prozesse darstellen. Da viele Gefäßerkrankungen mit inflammatorischen und thrombotischen Prozessen einhergehen, sind MP nachweisbar und bekommen sowohl als Diagnostikum (Surrogatmarker) als auch als pathophysiologischer Baustein vaskulärer Erkrankungen zunehmende Bedeutung.

Summary

Microparticles (MP) are small cell vesicles that are released by activated or apoptotic cells and that are amenable to quantification in peripheral blood. MP consist of the cytoplasm and the cell membrane of their cell of origin, which allows for their assignment to these cells. By the detection of the respected MP one can conclude to the functional status of the cell of origin. It is known that MP confer specific information between cells and contribute to inflammatory and coagulatory processes. They are detectable in many acute and chronic vascular diseases as a surrogate marker for disease activity but also play a role in the pathophysiology of vascular diseases.
