Preeclampsia is characterized by placental complement dysregulation.
Increasing evidence suggests that preeclampsia is associated with complement dysregulation. The origin of complement dysregulation in preeclampsia is unknown, and further unraveling this mechanism could provide both diagnostic tools and therapeutic targets. Because the placenta is believed to play a crucial role in the pathogenesis of preeclampsia, we investigated placentas from preeclamptic wo...
متن کاملInnate Immune System and Preeclampsia
Normal pregnancy is considered as a Th2 type immunological state that favors an immune-tolerance environment in order to prevent fetal rejection. Preeclampsia (PE) has been classically described as a Th1/Th2 imbalance; however, the Th1/Th2 paradigm has proven insufficient to fully explain the functional and molecular changes observed during normal/pathological pregnancies. Recent studies have e...
متن کامل[The complement system].
The complement system may be activated by at least two different pathways: the clinical pathway involving C1, C4 and C2 and the alternative pathway involving properdin, C3, factor B and factor D. The classical pathway can be activated by antigen antibody complexes, while the alternative pathway can be activated by other substances such as natural polysaccharides. Both pathways lead to an activ...
متن کاملThe complement system
The mammalian complement system plays an important role in the immune defense in blood and interstitial fluids. This set of ~30, mostly multi-domain, plasma proteins and cell-surface receptors enables the host to recognize and clear invading pathogens and altered host cells, while protecting healthy host cells and tissues. In addition to humoral immune defense, complement proteins are produced ...
متن کاملThe complement system
The system of plasma proteins called complement was so-named because it complements the activity of antibody in the lysis of bacteria. It has a central role in host defence against many micro-organisms and in the modulation of inflammatory reactions, an activity that has been illuminated by the study of humans with naturally occurring deficiencies of complement. Complement is activated by three...
