A popular hypothesis explaining the cause of pre-eclampsia is immune maladaptation(14).To date, the etiology of preeclampsia is not completely understood, however an increasing body of evidence indicates the involvement of the immune system in the form of faulty tolerance to the conceptus as an fundamental part of the pathogenesis(50).The immune system has been incriminated in the pathophysiology of preeclampsia with alterations in the cellular immunity and cytokines production that are work toward the maintenance of pregnancy(76). The maternal immune response against the fetus and placenta has too been proposed to have an central role in the pathogenesis of preeclampsia(185).

In contrast to normal pregnancy, there are indications of increased inflammatory responses and also of an immune deviation toward Th1 in the established preeclamptic pregnancy (183). Accompanied by a shift in the direction of Th1-type immunity as identified by the increased IL-2/IL-4 ratio and IFN- γ /IL-4 ratio , there is too increased circulating levels of the pro-inflammatory cytokines IL-6 and TNF-α, also the chemokines IL-8 , interferon-inducible protein-10 (IP-10) and monocyte chemoattractant protein 1 (MCP-1), as well as the adhesion molecules intercellular adhesion molecule 1(ICAM-1) and vascular cell adhesion molecule 1 (VCAM-1), in preeclampsia as compared …show more content…

NK cells are usually disappeared by full term. Conversely, in preeclampsia, NK cells continue to be active in the maternal decidua. Activation of NK cells might be accountable for the Th1-predominant inflammatory response profile experiential in preeclampsia, with increased IFN- γ and TNF-α level. The NK cell-derived Th1 cytokines may thus have a role in the pathogenesis of preeclampsia, maybe by inhibiting trophoblast invasion locally, and/or by the induction of endothelial damage and systemic inflammation
