Natural killer (NK) cells are essential for establishment of human and rodent pregnancies. The function of these and other cytotoxic T cells (CTL) is controlled by stimulatory and inhibitory signaling. A role for cytotoxic cells during early pregnancy in cattle has not been described, but regulation of their function at the fetal-maternal interface is thought to be critical for conceptus survival. The hypothesis that the relative abundance of CTL and expression of inhibitory signaling molecules is increased by the conceptus during early pregnancy was tested...

BACKGROUND/AIMS: Mesenchymal stem cells (MSCs) play an important role in regulating angiogenesis and immune balance. Abnormal proliferation and function of MSCs were reported at maternal fetal interface in patients with pre-eclampsia (PE). Micro-RNA-495 was known to be upregulated in the MSCs derived from patients with PE. However, it is not clear whether the up-regulated miR-495 is related to the pathogenesis of PE. METHODS: We analyzed the expression of miR-495 in MSCs and umbilical cords derived from healthy pregnancies (NC) and PE, then we upregulated or downregulated the expression of miR-495 in MSCs derived from NC and tested the proliferation, apoptosis, migration, invasion, tube formation and senescence...

The comparison of the immunological state of pregnancy to an immunosuppressed host-graft model continues to lead research and clinical practice to ill-defined approaches. This Review discusses recent evidence that supports the idea that immunological responses at the receptive maternal-fetal interface are not simply suppressed but are instead highly dynamic. We discuss the crucial role of trophoblast cells in shaping not only the way in which immune cells respond to the invading blastocyst but also how they collectively react to external stimuli...

AIMS: Toll-like receptors (TLRs) form a group of pattern recognition receptors that play a major role in maintaining innate host immunity. Myeloid differentiation factor 88 (MyD88) is an adaptor molecule that is essential for signaling via the TLR family. To analyze the mechanism of the imbalance in the innate immune system mediated by TLRs-MyD88 in spontaneous abortion, we detected the expression of TLR-2, TLR-4, TLR-7, and MyD88 in placentae and deciduas. METHODS: The expression of TLR-2, TLR-4, TLR-7, and MyD88 in the placentae and deciduas of abortion-prone mice (n = 10) and normal pregnant mice (n = 10) were analyzed by immunochemistry, western blot, and real-time polymerase chain reaction...

In the third trimester of pregnancy, the human fetus has the capacity to process perceptual information [1-3]. With advances in 4D ultrasound technology, detailed assessment of fetal behavior [4] is now possible. Furthermore, modeling of intrauterine conditions has indicated a substantially greater luminance within the uterus than previously thought [5]. Consequently, light conveying perceptual content could be projected through the uterine wall and perceived by the fetus, dependent on how light interfaces with maternal tissue...

The well-established classic role of vitamin D is implicated in the regulation of the balance between calcium and phosphorus. Furthermore, vitamin D is also involved in many non-classic physiological processes, mainly including the regulation of cell proliferation, differentiation, apoptosis and immune function, participation in the inflammatory response and maintenance of genome stability function. During pregnancy, vitamin D receptor and its metabolic enzymes are expressed at the placenta and decidua, indicating the potential role in the mechanism of immunomodulation at the maternal-fetal interface...

BACKGROUND: Antiphospholipid syndrome (APS)-related immune factors are considered as an important cause of recurrent spontaneous abortion (RSA). Anticoagulant and anti-inflammatory treatments are believed to effectively improve adverse pregnancy outcomes by affecting the abnormal autoimmune response of the maternal-fetal interface. The aim of this study was to observe the clinical characteristics and treatment outcomes of anticoagulant regimens and anti-inflammatory plus anticoagulation regimens for APS-related RSA...

Immunological tolerance between fetal allograft and mother is crucial for pregnancy establishment and maintenance; however, these mechanisms particularly those during the latter part of pregnancy have not been definitively elucidated. The aim of this study was to examine the presence and potential function of innate immunity characteristic to the middle to late pregnancy. We first characterized up-regulated proteins in decidua from day 11 pregnant (P11) mice using 2D-PAGE, followed by MALDI-TOF/MS analysis...

Infection with Zika virus (ZIKV) is associated with human congenital fetal anomalies. To model fetal outcomes in nonhuman primates, we administered Asian-lineage ZIKV subcutaneously to four pregnant rhesus macaques. While non-pregnant animals in a previous study contemporary with the current report clear viremia within 10-12 days, maternal viremia was prolonged in 3 of 4 pregnancies. Fetal head growth velocity in the last month of gestation determined by ultrasound assessment of head circumference was decreased in comparison with biparietal diameter and femur length within each fetus, both within normal range...

Ample evidence exists for the presence of infectious agents at the maternal-fetal interface, often with grave outcomes to the developing fetus (i.e. zika virus, brucella, cytomegalovirus, toxoplasma). While less studied, pregnancy-related transmissible spongiform encephalopathies (TSEs) have been implicated in several species, including humans. Our previous work has shown that prions can be transferred from mother-to-offspring resulting in the development of clinical TSE disease in offspring born to CWD-infected muntjac dams (64)...

DC-NK cell interactions are thought to influence the development of maternal tolerance and de novo angiogenesis during early gestation. However, it is unclear which mechanism ensures the cooperative dialogue between DC and NK cells at the feto-maternal interface. In this article, we show that uterine NK cells are the key source of IL-10 that is required to regulate DC phenotype and pregnancy success. Upon in vivo expansion of DC during early gestation, NK cells expressed increased levels of IL-10. Exogenous administration of IL-10 was sufficient to overcome early pregnancy failure in dams treated to achieve simultaneous DC expansion and NK cell depletion...

CD8(+) T cells are the main candidates to recognize and respond to fetal HLA-C at the fetal-maternal interface, but data on the amount of peripheral CD8(+) T cells and their functions during the window of implantation in recurrent implantation failure (RIF) patients are limited. Peripheral blood was obtained from 56 women with RIF and 16 fertile women in the mid-luteal phase of the menstrual cycle, and the CD8(+) T cells were determined by FACS analysis. No statistical differences in the proportion of peripheral CD8(+) T cells were observed among the women with RIF and the control group...

The pathologies of the pregnancy complications pre-eclampsia (PE) and fetal growth restriction (FGR) are established in the first trimester of human pregnancy. In a normal pregnancy, decidual spiral arteries are transformed into wide diameter, non-vasoactive vessels capable of meeting the increased demands of the developing fetus for nutrients and oxygen. Disruption of this transformation is associated with PE and FGR. Very little is known of how these first trimester changes are regulated normally and even less is known about how they are compromised in complicated pregnancies...

We compared the number of CD4-positive (CD4(+)) and CD8-positive (CD8(+)) cells in severe and non-severe preeclampsia (PE), and in normal pregnancy. We also evaluated the expression of matrix metalloproteinase 9 (MMP-9) in CD4(+) and CD8(+) cells. Immunohistochemistry for CD4(+) and CD8(+) was performed on the decidua basalis of 15 severe and 13 non-severe PE women and compared to decidual tissue of 19 normal pregnancies (control group). Co-expression of MMP-9 with CD8(+) and CD4(+) cells was determined by double immunofluorescence staining...

Preeclampsia (PE) is a major complication of pregnancy in which the placenta is known to have shallow implantation into the uterine decidua. Studies have implicated soluble fms-like tyrosine kinase-1 (sFlt1), a soluble vascular endothelial growth factor (VEGF) receptor protein, in the pathogenesis of PE. sFlt1 has the ability to bind to and neutralize the angiogenic functions of VEGF and placental growth factor (PlGF). The presence of sFlt1 and its action in the endometrium is yet to be determined. We hypothesize that endometrial stromal cells (ESC) at the maternal-fetal interface may play a role in sFlt-1 regulation during pregnancy...

INTRODUCTION: We have previously shown that miRNAs produced from the Chromosome 19 MiRNA Cluster (C19MC), which are expressed almost exclusively in primate trophoblasts and are released into the maternal circulation, reduce viral replication in non-placental cells and can modulate migratory behavior of extravillous trophoblast. We sought to define the expression pattern of C19MC miRNA in early pregnancy and in response to viral infection in vitro and in vivo. METHODS: We prospectively followed women undergoing in vitro fertilization (IVF) and determined their blood level of C19MC miRNA using RT-qPCR...

Workshops are an important part of the IFPA annual meeting as they allow for discussion of specialised topics. At IFPA meeting 2016 there were twelve themed workshops, four of which are summarized in this report. These workshops related to various aspects of placental biology but collectively covered areas of decidual-trophoblast interaction, regulation of trophoblast invasion, immune cells at the maternal-fetal interface, and placental inflammation.

The present retrospective study investigated pregnancy rates, the incidence of pregnancy loss and large offspring syndrome (LOS) and immune-related gene expression of sheep and goat somatic cell nuclear transfer (SCNT) pregnancies. We hypothesised that significantly higher pregnancy losses observed in sheep compared with goat SCNT pregnancies are due to the increased amounts of T-helper 1 cytokines and proinflammatory mediators at the maternal-fetal interface. Sheep and goat SCNT pregnancies were generated using the same procedure...

Angiogenesis is an essential process for proper functioning of the female reproductive system and for successful pregnancy realization. The multitude of factors required for physiological angiogenesis and the complexity of regulation of their temporal-spatial activities contribute to aberrations in human fertilization and pregnancy outcomes. In this study, we reviewed the current knowledge of the temporal expression patterns, functions, and regulatory mechanisms of angiogenic factors during foliculogenesis, early implantation/placentation and embryo development, as well as recurrent spontaneous abortions...

PROBLEM: Several mechanisms contribute to the tolerogenic state observed during pregnancy, such as the activity of the enzyme indoleamine 2, 3-dioxygenase (IDO). This initializes the catabolism of tryptophan, inducing T cells to apoptosis due to its deprivation and by the action of its catabolites in the placental microenvironment. Progesterone plays an important part on immunological tolerance mechanisms during pregnancy; however, there is no evidence it is related to IDO activity. Thus, this study aimed to investigate progesterone influence on the maternal-fetal interface of pregnant Wistar rats, by identifying IDO positive cells by immunophenotyping and flow cytometry under exogenous progesterone supplementation...
