Occurrence of neutrophil extracellular DNA traps (NETs) in pre-eclampsia: a link with elevated levels of cell-free DNA?

Abstract:

:Manifest pre-eclampsia is associated with activation of peripheral neutrophils as well as elevations in maternal cell-free DNA. For this reason, we were very intrigued by recent reports indicating that activated circulatory neutrophils secrete nuclear DNA to generate extracellular DNA lattices, termed NETs (neutrophil extracellular traps). Our preliminary data indicate that placental syncytiotrophoblast microparticles, which are released in elevated amounts in pre-eclampsia, can induce NETs in isolated neutrophils. Furthermore, we found evidence for the increased presence of NETs directly in the intervillous space of pre-eclamptic placentae. Therefore, these newly discovered entities may be implicated in the underlying etiology of this disorder.
