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...

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...

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...

Preterm birth continues to be a significant global health care issue, due to our lack of understanding of the mechanisms that drive human labour and delivery. Toll-like receptors (TLRs) are essential in triggering an inflammatory response in human gestational tissues, leading to the production of pro-inflammatory and pro-labour mediators, and thus preterm birth. The aims of this study were to determine whether the adaptor molecules associated with TLR2, TLR3 and TLR5 signalling are involved in human myometrium...

The aim of this study was to understand the clinical features of antiphospholipid syndrome (APS)-complicated pregnancies and evaluate risk factors for the adverse pregnancy outcomes. This multicenter study evaluated live-birth rates according to therapy modality for APS and risk factors of pregnancy loss in 81 pregnancies. Risk factors for pregnancy complications, including premature delivery before 34 gestational weeks, hypertensive disorders of pregnancy, thrombocytopenia, and light-for-date neonate, were evaluated in 51 women who received low dose aspirin (LDA) plus unfractionated heparin (UFH) and delivered after 24 GW...

The relevance of antiphospholipid (aPL), antinuclear (ANA) or antithyroid (ATA) antibodies in women undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) are controversial. The present study aims to investigate which autoantibodies are associated with the pregnancy outcome of patients undergoing first IVF/ICSI treatment. A total of 3763 IVF/ICSI patients were recruited from January to December 2015. Forty-five patients positive for aPL presenting adverse outcomes in their first cycle received low-dose aspirin treatment before the second transfer...

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...

Preeclampsia is a pregnancy disorder characterized by imbalance between pro- and anti-inflammatory cytokines associated with high plasma levels of uric acid and Interleukin-1 beta (IL-1β). The inflammasome is a protein complex that mediates innate immune responses via caspase-1 activation promoting secretion of IL-1β and IL-18 in their active forms, and also release of the high-mobility group box 1 protein (HMGB1). As the placenta seems to play an important role in the pathogenesis of PE, the present study investigated the expression of genes and proteins related to the inflammasome in placentas from pregnant women with severe preeclampsia...

Epithelial cells lining the vagina are major components of genital tract immunity. The influence of the vaginal microbiome on properties of host epithelial cells is largely unexplored. We evaluated whether differences in the most abundant lactobacilli species or bacterial genera in the vagina of first trimester pregnant women were associated with variations in the extent of stress and autophagy in vaginal epithelial cells. Vaginal swabs from 154 first trimester pregnant women were analyzed for bacterial composition by amplification and sequencing of the V1-V3 region of bacterial 16S rRNA genes...

The physiopathology of endometriosis is not completely understood and its progression is associated with a local and systemic inflammatory reaction. It is important to clarify the potential role of the immune system to better understand its implication in the pathogenesis of endometriosis, which includes the study of the role of B cells and antibodies. The aim of this study was to review the literature about the role of B lymphocytes in endometriosis. A search for "endometriosis", "B cells" and "B lymphocytes" in databases resulted in 140 citations; after applying inclusion and exclusion criteria, a total of 22 studies were assessed...

A lack of immunologic tolerance of the mother toward her child and in placentation can result in early or late pregnancy complications, including implantation failure, miscarriage, preeclampsia, and fetal growth restriction. Seminal plasma has the potential of influencing the maternal immune system for acceptance of the semi-allogeneic fetus. Here we elaborate on studies which provide evidence that an optimal balance of pro-inflammatory and immunomodulatory factors is necessary for the induction of immunologic tolerance and the process of implantation and placentation...

Autophagy is an evolutionarily conserved process in eukaryotes to maintain cellular homeostasis against stress. This process has two main functions: producing energy and quality control of intracellular proteins. During early pregnancy, extravillous trophoblasts (EVTs) invade the uterine myometrium and migrate along the lumina of spiral arterioles under hypoxic and low-nutrient conditions. Autophagy activation is observed in EVTs under these conditions, suggesting that EVTs use autophagy for adjusting to such harsh conditions...

Term labor in humans is associated with increased oxidative stress (OS) -induced senescence and damages to amnion epithelial cells (AECs). Senescent fetal cells release alarmin high-mobility group box 1 (HMGB1) and cell-free fetal telomere fragments (cffTF) which can be carried by exosomes to other uterine tissues to produce parturition-associated inflammatory changes. This study characterized AEC-derived exosomes under normal and OS conditions and their packaging of HMGB1 and cffTF. Primary AECs were treated with either standard media or oxidative stress-induced media (exposure to cigarette smoke extract for 48h)...

Clinical differences, maternal risk factors and pregnancy outcomes of deliveries complicated by early- (delivery<34 weeks) and late-onset (delivery≥34 weeks) preeclampsia were studied in a cohort of women in Reunion Island during 15 years (period 2001-2015; N=62,230 pregnancies). The overall preeclampsia rate in singleton pregnancies was 2.37%. Early- and late-onset preeclampsia rates were 0.75% and 1.5% respectively, and the trend for each type of disease was stable over time. In both form of preeclampsia, smoking during pregnancy was a protective factor and associated risk factors were: older age, primiparity, pre-existing diabetes, chronic hypertension, higher pre-pregnancy body mass index and obesity, infertility treatment, history of renal disease and hypercholesterolemia (all p<0...
