The aim of this prospective study was to determine clinical factors associated with adverse pregnancy outcomes in women with systematic lupus erythematosus (SLE). Fifty-six pregnancies from 46 women with SLE were enrolled. Risk factors for pregnancy loss, premature delivery, hypertensive disorders of pregnancy (HDP), and light-for-date neonate (LFD), were evaluated. Univariate and multivariate logistic regression analyses revealed a history of two or more pregnancy losses before 10 gestational weeks (GW) (OR 11...

Preeclampsia is a dangerous pregnancy complication, which is often associated with fetal growth restriction and can have serious life-long effects for both mother and baby. While the establishment of the placenta in the first trimester is the sentinel event in the development of preeclampsia little is known of the critical mechanisms of placentation that lead to the syndrome. Locally produced inflammatory cytokines are thought to play a role in the development of preeclampsia. This review summarizes the evidence that interleukin 11 is dysregulated in preeclampsia and contributes to the initiation of preeclampsia via effects on placentation...

We performed a prospective cohort study in 197 pregnant women. Peripheral blood was collected between 5 and 16 weeks of gestation. Intracellular cytokine analysis and immunophenotype were performed by flow-cytometry. Serum levels of cytokines and chemokines were analyzed by multiplex assay. 86 patients were eligible for the analysis and 10.5% (n=9) developed preeclampsia. Patients with preeclampsia had significantly higher percentage of CD3+CD4+TNFα+ T helper (Th) 1 cells (45.4±10.3 vs 37.1±8.5, P=0.032) and CD3+CD4+IL17+ Th 17 cells (2...

In addition to being immunomodulatory, Progesterone-Induced Blocking Factor (PIBF) plays a role in cell cycle regulation and invasion. The full length protein is associated with the pericentriolar satellites and as such, it is crucial for maintaining the integrity of spindle poles during mitosis. Another suggestive evidence for the involvement of PIBF in tumour progression is the fact that the PIBF gene has been identified on chromosome 13 in the region associated with breast cancer susceptibility. Earlier we showed that PIBF differentially regulates the invasiveness of trophoblast and tumour cell lines...

The control of complement activation within embryo-endometrium environment is critical for embryo survival. Cell evasion from complement attack requires interaction of complement regulatory proteins (CRPs) with cell adhesion αvβ3 integrin. We aim to compare the expression of CRPs in endometria of women with and without endometriosis and to examine the molecular interaction of decay accelerating factor (DAF) with αvβ3 integrin. Endometrial expression of Membrane cofactor protein (CD46), Decay accelerating factor (DAF), Membrane attack complex inhibitory factor (CD59) and β3 integrin subunit were determined through menstrual cycle by immunohistochemistry...

Early administration of low dose acetyl salicylic acid (Aspirin) in high risk women reduces the risk of early onset preeclampsia. This study aims to investigate the effect of aspirin on trophoblast integration and the its effect on angiogenic and invasive pathways in an in-vitro model of preeclampsia. Red fluorescent-labeled human uterine myometrial microvascular endothelial cells (UtMVECs) were seeded on matrigel to form endothelial networks. Green fluorescent-labeled trophoblastic HTR-8/SVneo cells were co-cultured with the endothelial networks with/without TNF-a (0...

The maternal-fetal interface undergoes dynamic changes to allow the fetus to grow and develop in the uterus, despite being recognized by the maternal immune cells. Within the innate immune system, decidual natural killer cells and antigen presenting cells (including macrophages and dendritic cells) that comprise a large proportion of the decidual leukocyte populations play an important role in modulating trophoblast invasion, angiogenesis and vascular remodeling. On the other hand, within the adaptive immune system, CD8(+) T cells, effector CD4(+) T cells, Foxp3(+) regulatory T cells and CD4(+)HLA-G(+) suppressor T cells are identified as potential players in maintaining immune tolerance toward the semi-allogeneic fetus...

The testis has been described in animal models as a site of immune privilege, which protects spermatids against tissue damage during inflammation. Myeloid cells, including macrophages and dendritic cells (DC), are defined as key players in the testicular immune privilege in animal models. However, their distribution and frequency in human testis remain poorly described. To overcome the challenges related to tissue sampling, we obtained testicular tissue from men under hormonal therapy who elected to have sex reassignment surgery (SRS)...

The presence of genital inflammatory responses and a compromised vaginal epithelial barrier have been linked to an increased risk of HIV acquisition. It is important to assure that application of candidate microbicides designed to limit HIV transmission will not cause these adverse events. We previously developed high resolution in vivo imaging methodologies in sheep to assess epithelial integrity following vaginal application of a model microbicide, however characterization of genital inflammation in sheep has not been previously possible...

Pre-eclampsia is a disease of pregnancy affecting 5%-8% of all pregnancies and a leading cause of maternal and fetal mortality. Despite improvements in the diagnosis, there is no effective method for prevention and treatment. While studies in women are of critical importance, investigation of pathological mechanisms in pregnant women is necessarily limited, and the ability to establish cause and effect relationships, difficult. Mouse models have been instrumental in defining pathogenic mechanisms in preeclampsia and in the identification of pravastatin as a potential treatment to prevent pregnancy complications associated with placental dysfunction...

Thyroid autoimmunity (TAI) appears to play a crucial role in female infertility, recurrent pregnancy loss and IVF failure. Thyroid autoantibodies against thyroid peroxidase and thyroglobulin have been shown to represent an independent risk factor for infertility and miscarriage. Moreover, thyroxin hormone administration reduces the risk of obstetrical complications in TAI positive women. The aim of our present study was to investigate the immunological background of female infertility and recurrent pregnancy loss in euthyroid and subclinical hypothyroid women with TAI focusing on innate immunity...

Immune tolerance at feto-maternal interfaces is a complex phenomenon. Although maternal decidual macrophages are well-known immune cells, little is known about fetal-derived macrophages (Hofbauer cells) within chorionic villi. Preeclampsia (PE) is a major cause of maternal mortality in the field of obstetrics, and the innate immunological role of maternal decidual macrophages is well known. In this study, we assessed the differential phenotypes and marker expression in fetal macrophages, known as dendritic cell-specific ICAM-grabbing non-integrin (DC-SIGN)-positive Hofbauer cells...

Gestational diabetes mellitus (GDM) is still a clinical challenge around world. Inflammation contributes to the pathogenesis of GDM, the precise underlying mechanism remains to be explored. IL-37 and 38 play important role in autoimmunity, but their role in the development of GDM is unclear. Using histopathology and immunohistochemistry, the thickness of the umbilical artery, the area of capillaries within the placental chorionic villi, and the production of IL-37/38 were determined. Placental mRNA of IL-37/IL-38 from GDM and Non-GMD was measured using qRT-PCR...

Preeclampsia results from a complex interaction between immunological alterations, endothelial dysfunction, and insulin resistance. Inositol second messengers are known to be involved in metabolic signaling and are highly expressed during preeclampsia. In the past two decades, several studies were published on different aspects where these molecules are involved. It appears that maternal increase of IPG-P content in all tissues and fluids reflects an increased production of inositol mediators on the fetal side in preeclampsia...

Bronchopulmonary dysplasia (BPD) and BPD-associated pulmonary hypertension (BPD-PH) are chronic inflammatory cardiopulmonary diseases with devastating short- and long-term consequences for infants born prematurely. The immature lungs of preterm infants are ill-prepared to achieve sufficient gas exchange, thus usually necessitating immediate commencement of respiratory support and oxygen supplementation. These therapies are life-saving, but they exacerbate the tissue damage that is inevitably inflicted on a preterm lung forced to perform gas exchange...

Antiphospholipid syndrome (APS) is an autoimmune condition that is associated with thrombosis and morbidity in pregnancy. The exact mechanisms by which these associations occur appear to be heterogeneous and are not yet well understood. The aim of this study was to identify and analyze publications in recent years to better understand the diagnosis and its contribution to monitoring APS among women with recurrent miscarriage (RM). This systematic review and meta-analysis was conducted using the PubMed and Web of Knowledge databases, with articles published between 2010 and 2014, according to the PRISMA statement...

For some time, reproductive immunologists have worked to understand the balance between maternal tolerance of the fetus, maternal health, and fetal protection which leads to successful pregnancy in mammalian species. We have always understood the potential importance of multiple factors, including nutrition, genetics, anatomy, hormonal regulation, environmental insult and many others. Yet, we still struggle to combine our knowledge of these factors and immunology to finally understand complex diseases of pregnancy, such as preeclampsia...

During pregnancy, prolactin (PRL) is a neuro-immuno-cytokine that contributes actively to the crosstalk between the immune and endocrine systems and, thus, to the creation of an immune-privileged milieu. This work aims to analyze the capacity of PRL to modulate the synthesis and secretion of pro-inflammatory markers associated with labor. Studies were conducted using human fetal membranes at term mounted in a model of two independent chambers. The choriodecidual region was stimulated with 500-ng/mL lipopolysaccharide (LPS), and the amnion and choriodecidual region were co-simulated with different concentrations of PRL that can arise during pregnancy: 250, 500, 1000, and 4000ng/mL...

In addition to natural killer cells, other innate lymphoid cells have recently been identified in the mouse and human uterus, but their roles in successful pregnancy remain poorly defined. In this study, we examined the dynamic changes of uterine innate lymphoid cells throughout pregnancy in mice. We found that the total number of uterine innate lymphoid cells markedly increased at early-gestation. Among the three groups of uterine innate lymphoid cells, the number of the group 2 uterine innate lymphoid cells increased the most during pregnancy...
