Recurrent spontaneous abortion (RSA) is a common health problem that affects about 5% of fertile women, when it occurs for unknown reasons, it is called unexplained recurrent spontaneous abortion (URSA). Traditional Chinese medicine, such as Bu-Shen-Yi-Qi formula which consists of Dangshen, Tusizi, Baizhu, Baishuo, Duzhong, Sangjisheng, Sugeng, and Tiaohuangqin, has played an invaluable role in the treatment of RSA since ancient times. However, the mechanism of how it takes effect is still not clear. To identify Bu-Shen-Yi-Qi formula could modulate immune condition at maternal-fetal interface via its effect on trophoblasts, HTR-8 of different treatment were co-cultured with peripheral or decidual natural killer (NK) cells, and the receptors such as NKP30 and NKP46 expression on NK cells were measured by flow cytometry (FCM)...

The hypothesis of this study was that the leukocyte populations and expression levels of genes related to immune response, growth factors and apoptosis would be altered at the fetal-maternal interface in somatic cell nuclear transfer (SCNT)-generated sheep pregnancies. Placental and endometrial samples from sheep pregnancies established by SCNT and natural breeding (control) were collected at 45 days and at term. Expression of genes related to growth factors, apoptosis and immune response was examined using quantitative reverse transcription polymerase chain reaction...

Toxoplasma gondii is a major source of congenital disease worldwide, but the cellular and molecular factors associated with its vertical transmission are largely unknown. In humans, the placenta forms the key interface between the maternal and fetal compartments and forms the primary barrier that restricts the hematogenous spread of microorganisms. Here, we utilized primary human trophoblast (PHT) cells isolated from full-term placentas and human midgestation chorionic villous explants to determine the mechanisms by which human trophoblasts restrict and respond to T...

The imbalance of Th1/Th2 cytokines is well known in recurrent spontaneous abortion (RSA) mouse model. Mesenchymal stem cells (MSCs) possess potent immunoregulatory properties that could modulate the Th1 cytokine responses in benefit of Th2 types. In this study, we aimed to analyze the local and systemic balance of Th1/Th2 cytokines following MSCs therapy. Syngeneic adipose derived MSCs were administered to abortion prone mice during the implantation window. The abortion rate was determined and IL-4, IL-6, IL-12, IL-2, IFN-γ and GM-CSF gene expression was evaluated by Real-Time-PCR in decidual and placental tissues of pregnant mice at day 13...

Preterm birth is widespread and causes 35% of all neonatal deaths. Infants who survive face potential long-term complications. A major contributing factor of preterm birth is infection. We investigated the role of Interleukin 22 (IL22) as a potential clinically relevant cytokine during gestational infection. IL22 is an effector molecule secreted by immune cells. While the expression of IL22 was reported in normal non-pregnant endometrium and early pregnancy decidua, little is known about uterine IL22 expression during mid- or late gestational stages of pregnancy...

Human leucocyte antigen-G (HLA-G), a non classical class Ib gene is mainly expressed on extravillous trophoblasts at the fetal-maternal interface. HLA-G molecule is considered to play an important role in maternal immune suppression during pregnancy. 14bp insertion/deletion polymorphism (rs66554220) in exon 8 of the HLA-G gene influences HLA-G mRNA stability and isoform splicing patterns. In the present study, 202 RM women with two or more than two consecutive miscarriages, their 202 partners and 204 fertile control women with at least one live birth and no miscarriages were analyzed for 14bp insertion/deletion polymorphism...

Chemokines and atypical chemokine receptors (ACKRs; also known as chemokine decoy receptors) play an important role in reproductive immunology by recruiting leukocytes during early pregnancy. The aim of this study was to determine the expression of C-C motif chemokine ligand 2 (CCL2) and ACKRs in the endometrium during estrous cycle and early pregnancy, and to investigate the functional effects of CCL2 on porcine uterine luminal epithelial (pLE) cells. Our results indicated that CCL2, ACKR1, ACKR3, and ACKR4 were strongly detected in the glandular and luminal epithelium of the endometrium during early pregnancy compared to that in non-pregnant pigs...

Natural killer (NK) cells are present in large populations at the maternal-fetal interface during early pregnancy. However, the role of NK cells in fetal growth is unclear. Here, we have identified a CD49a+Eomes+ subset of NK cells that secreted growth-promoting factors (GPFs), including pleiotrophin and osteoglycin, in both humans and mice. The crosstalk between HLA-G and ILT2 served as a stimulus for GPF-secreting function of this NK cell subset. Decreases in this GPF-secreting NK cell subset impaired fetal development, resulting in fetal growth restriction...

BACKGROUND: Prenatal ambient fine particulate matter (PM2.5) and maternal chronic psychosocial stress have independently been linked to changes in mithochondrial DNA copy number (mtDNAcn), a marker of mitochondrial response and dysfunction. Further, overlapping research shows sex-specific effects of PM2.5 and stress on developmental outcomes. Interactions among PM2.5, maternal stress, and child sex have not been examined in this context. METHODS: We examined associations among exposure to prenatal PM2...

Mammalian pregnancy requires specific interactions between the conceptus and its mother that involve the endocrine system and adhesion molecules. The relation between adhesion molecules and their ligands at the fetal-maternal interface is crucial for developing a successful implantation. Progesterone (P4) and estrogen (E2) secreted by the porcine conceptus are required for the relation to be established. We investigated the expression of αvβ3 integrin and its ligand, fibronectin (FN), at the placental interface, and E2 and P4 concentrations in both serum and maternal and fetal placental extracts during placentation in swine...

Decidual stromal cells form the largest proportion of maternal cells at the maternal-fetal interface. Our aim was to investigate the role of the pre-eclampsia associated decidual activin receptor, ACVR2A, in regulating trophoblast functions at this interface. St-T1b and HTR-8/SVneo cell lines were used to model decidual stromal and trophoblast cells respectively. St-T1b conditioned medium inhibited HTR-8/SVneo adhesion, proliferation, migration and invasion; all effects that were attenuated by decidual ACVR2A siRNA transfection...

We aimed to investigate the expression of suppressors cytokine signaling (SOCS)-3, transforming growth factor (TGF)-β and indoleamine 2,3-dioxygense (IDO) and to analyse the relationship of SOCS3 and TGF-β with IDO expression in early pregnancy chorionic villi and decidua in the maternal-fetal interface. Western blot analysis and immunohistochemical method were used to detect the expression of TGF-β, SOCS3 and IDO in chorionic villi and decidua tissues of normal pregnant women. SOCS3, TGF-β and IDO protein was identified in chorionic villi and decidua tissues of normal pregnant women and there was a negative correlation between the expression of IDO and SOCS3, but TGF-β expression was positively correlated with IDO expression...

The decidua basalis and placental chorionic villi are critical components of maternal-fetal interface, which plays a critical role in normal placental development. Failure to form a proper maternal-fetal interface is associated with clinically important placental pathologies including preeclampsia and fetal growth restriction. Placental trophoblast cells are well known for their critical roles in establishing the maternal-fetal interface; however accumulating evidence also implicates mesenchymal stem/stromal cells that envelop the maternal and fetal blood vessels as playing an important role in the formation and efficient functioning of the interface...

The risk factors for preeclampsia, extremes of maternal age, changing paternity, concomitant maternal autoimmunity, and/or birth intervals greater than 5 years, suggest an underlying immunopathology. We used peripheral blood and lymphocytes from the UteroPlacental Interface (UPI) of 3rd trimester healthy pregnant women in multicolor flow cytometry-and in vitro suppression assays. The major end-point was the characterization of activation markers, and potential effector functions of different CD4-and CD8 subsets as well as T regulatory cells (Treg)...

The emergence of congenital Zika virus (ZIKV) disease, with its devastating effects on the fetus, has prompted development of vaccines and examination of how ZIKV breaches the maternal-fetal barrier. Infection of placental and decidual tissue explants has demonstrated cell types at the uterine-placental interface susceptible to infection and suggests routes for transmission across the placenta and amniochorionic membrane. ZIKV replicates in proliferating Hofbauer cells within chorionic villi in placentas from severe congenital infection...

The survival of allogeneic fetus during pregnancy contradicts the laws of immune responses. Behind this paradoxical phenomenon, the mechanism is quite complex. Indoleamine-2,3-dioxygenase (IDO) is the first and rate-limiting enzyme of tryptophan catabolism. Emerging evidence shows that IDO is expressed at the maternal-fetal interface, including trophoblast cells, decidual stroma cells, decidual immune cells (eg, natural killer cells, T cells, and macrophages), and vascular endothelial cells of decidua and chorion...

PROBLEM: We hypothesized that trophoblast expression of Ccl25 attracts a specific leukocyte cell population to the implantation site for local regulation. METHOD OF STUDY: Mice blastocysts, ectoplacental cones, and decidua at gestational days 3.5-7.5 were evaluated for Ccl25 and Ccr9 expressions. Peripheral availability and characterization of Ccr9+ leukocytes were determined by flow cytometry. Leukocyte chemotaxis was assessed in the presence of Ccl25 recombinant protein and embryos using antisense oligomers (ODNs) to Ccl25 and Ccr9 neutralizing antibody...

During pregnancy, immune cells infiltrate the placenta at different stages of fetal development. NK cells and macrophages are the most predominant cell types. These immune cells play pleiotropic roles, as they control spiral artery remodeling to ensure appropriate blood supply and maintain long-term tolerance to a true allograft; yet, they must be able to mount appropriate immune defenses to pathogens that may threaten the fetus. Whether the same cell type accomplishes all these tasks or if there are dedicated subsets remains controversial...

The current lack of knowledge about the effect of maternally administered drugs on the developing fetus is a major public health concern worldwide. The first critical step toward predicting the safety of medications in pregnancy is to screen drug compounds for their ability to cross the placenta. However, this type of preclinical study has been hampered by the limited capacity of existing in vitro and ex vivo models to mimic physiological drug transport across the maternal-fetal interface in the human placenta...
