Changes in the Ratio of Tc1/Tc2 and Th1/Th2 Cells but Not in Subtypes of NK-Cells in Preeclampsia

Abstract: It has been suggested that natural killer (NK) cell activity and Th1 immunity may be involved in the pathogenesis of preeclampsia. This study aimed to investigate the immunophenotypes of NK cells and type 1/type 2 immunity in both decidua and maternal peripheral blood between normal (n=11) and preeclamptic pregnant women (n=20) by flow cytometry. The results showed that no significant difference was observed between patients and controls by detecting CD56 + CD69 + and CD56 + CD94 + NK cells in both peripheral … Show more

“…However, in PBMC derived from some women with PE, Th1 cytokines expression increased and Th2 cytokines expression decreased, implying the balance shifts toward Th1-type immunity[5][7]. Our previous data also showed the decreased percentages of Tc2 and Th2 cells and the increased ratios of Tc1/Tc2 in both decidua and maternal peripheral blood of PE patients [8]. Moreover, the increase of Th1-type cytokine TNF-α was thought to associate with PE [9][12].…”

“…9 The dNK or pNK cells culture medium was supplemented with various concentration of CYR61, LM609, U0126, LY294002, or DMSO (served as a control). Peripheral blood NK (pNK) cells were isolated and purified as previously described and served as controls.…”

“…Density of DCs drastically affects antigen presentation in uencing the outcome of T cell responses. The CD4 T cell pro le in PE patients is altered as the number of Th2 cells is decreased in the pre-eclamptic decidua, compared to normal pregnancy associated decidua [19]. Along these lines, the ability of DCs to induce regulatory T cells is impaired in PE patients [20], disrupting the tolerogenic environment characteristic of a normal pregnancy.…”
