Abstract
Immune checkpoint molecules may play a crucial role in safeguarding pregnancy by regulating immune responses at the maternal-fetal interface. In this study, we aim to investigate the expression of PD-1, GITR, HLA-G, and CTLA-4 on T cell subsets in peripheral blood (PB), retroplacental blood (RPB), and cord blood (CB) in normal pregnancy (NP), preeclampsia (PE) and gestational diabetes mellitus (GDM). PB, RPB, and CB were collected immediately after delivery, and the expression of PD-1, GITR, HLA-G, and CTLA-4 on T cell subsets were measured by flow cytometric analysis. The proportions of Tregs in PB, RPB, and CB from NP were significantly higher than those of PE and GDM (P < 0.01, respectively). PD-1+ and GITR+ T cell subsets (CD3+, CD4+, and CD8+ T cells, and Tregs) in PB, as well as PD-1+ T cell subsets in RPB from NP, were significantly higher than those of PE and GDM (P < 0.01, respectively). In NP, PE, and GDM, the proportion of PD-1+ Tregs was significantly decreased in CB as compared to those of PB and RPB (P < 0.05, respectively) and the proportion of GITR+ Tregs was significantly higher in PB as compared to those of CB and RPB (P < 0.01, respectively). The proportion of HLA-G+ Tregs in PB was significantly lower than those of CB and RPB (P < 0.01, respectively). In conclusion, decreased PD-1+ and GITR+ T cell subsets and decreased proportion of Tregs in PB and RPB may play a role in chronic inflammatory immune activation of effector T cells in PE and GDM.

Abstract
Preeclampsia (PE) is a pregnancy-specific disorder representing a major cause of maternal and perinatal morbidity and mortality. Invasive and migratory phenotypes are acquired by trophoblasts through the process of epithelial-mesenchymal transition (EMT). Studies have shown that trophoblast EMT events are dysregulated in PE and play an important role in its development. Dysregulation of interleukin (IL)-27 and IL-27R (T-cell cytokine receptor (TCCR)/WSX -1) is relevant to PE. In this study, our results demonstrated that IL-27 did not significantly affect the proliferation and apoptosis of HTR -8/SVneo trophoblast cells, while it did significantly inhibit trophoblast invasion and migration. The expression of EMT-related proteins in HTR-8/SVneo cells and extravillous explants was detected after treatment with IL-27. Expression of epithelial markers was increased, and mesenchymal marker expression was reduced. Furthermore, we found that IL-27 could induce significant phosphorylation of Signal Transducer and Activator of Transcription 1 (STAT1) and Signal Transducer and Activator of Transcription 3 (STAT3) in a time-dependent manner in HTR-8/SVneo cells. Selective inhibitors of STAT1 (STAT1 siRNA) and STAT3 (STAT3 siRNA) were used to determine whether both STAT1 and STAT3 are required for IL-27-mediated inhibition of EMT. STAT1 inhibition in IL-27-treated cells attenuated the IL-27 effect, while the inhibition of STAT3 activation had no effect on the development of the epithelial phenotype. These results demonstrate that IL-27 may inhibit trophoblast cell migration and invasion by affecting the EMT process through an STAT1-dominant pathway in PE.

Abstract
Preeclampsia is a multi-system hypertensive disorder of pregnancy, with significant rates of maternal and neonatal morbidity. It represents a major cause of preterm birth, as definitive treatment demands fetal delivery. Although its pathophysiology is complicated, placental hypoxia and endothelial dysfunction constitute established pathogenetic steps of the disease. Inflammation is considered to be a crucial mediator of preeclampsia process, as an imbalance between TH 1, TH 2, and TH 17 immune responses is observed. The present review accumulates current knowledge about the contribution of interleukins in preeclampsia, summarizing the pathways through which each interleukin exerts its function in the disease. Also, the role of genetic polymorphisms is explored and the predictive efficacy of maternal serum interleukin levels is evaluated. Finally, recommendations about the safe interpretation of the outcomes, as well as guidance for future research, are provided.
