OBJECTIVES: An imbalance of angiogenic placental factors such as endoglin, soluble fms-like tyrosine kinase 1(sFlt-1) and placental growth factor (PlGF) has been implicated in the pathophysiology of preeclampsia. This study aimed to evaluate serum levels of sFlt-1, PlGF and endoglin in women with primary and secondary antiphospholipid Syndrome (APS) and systemic lupus erythematosus (SLE) longitudinally through pregnancy. MATERIAL AND METHODS: Serum levels of sFlt-1, PlGF and endoglin were measured prospectively at 4-week intervals (from gestational weeks 12-36) in 17 women with primary APS (PAPS), 18 women with secondary APS (SAPS), and 23 women with SLE...

In HIV infection, increased adverse perinatal outcomes reported among HIV-associated pregnancies are not fully understood. Currently, microbial product translocation (MT) from a permeable mucosa is demonstrated as a driver of inflammation, and may contribute to preterm delivery in HIV. Here, our results showed that plasma LPS levels (a representative marker of MT) were increased in HIV-infected women in the first and second trimester. Progesterone levels were significantly decreased in HIV-infected subjects in the first trimester and second trimester...

INTRODUCTION: Corticotherapy is the leading medication worldwide for patients with history of repeated implantation failures (RIF) after IVF/ICSI. Nevertheless, we still do not know its local mechanism of action, hence its precise indication. Our objective is to document the impact of prednisone on the endometrial expression of immune biomarkers (CD56 cells count, IL-18/TWEAK, IL-15/Fn-14 mRNA ratio) at the time of uterine receptivity in a RIF population. MATERIALS AND METHOD: An endometrial biopsy was realized in the mid luteal phase for immune profiling: IL-15/Fn-14 and IL-18/TWEAK mRNA ratios were determined by quantitative RT-PCR and CD56 mobilization per IHC...

An elevated level of insulin growth factor (IGF-1) in rat uterine fluid has been shown to exert detrimental effects of embryo development possibly leading to an increase in pregnancy loss. Interestingly, the administration of somatostatin to rats undergoing superovulation reduced IGF-1 levels in uterine luminal fluid and thus reversed its deleterious effects on embryo development and increased the number of normal embryos. Therefore, we investigated whether serum levels of IGF-1 correlate with the incidence of pregnancy loss following IVF...

Presence of the CD200 immune check-point inhibitor at the feto-maternal interface is linked to prevention of spontaneous abortion in mice and humans. In human missed abortions (MA), absence of Th17-driven inflammation has been attributed to expression of villus trophoblast CD200 quantified using immunohistochemistry. While rapid aneuploidy (QF-PCR) testing linked low CD200 to pregnancy failure, data showing normal VT CD200 in first trimester normal pregnancy and in abortion of chromosomally abnormal embryos has not been demonstrated...

BACKGROUND: Autoimmune (type 1) diabetes (T1D) is a frequent chronic disease in children and adolescents globally. Gestational enterovirus (EV) infections have been associated with an increased risk for T1D in the offspring. We test the hypothesis that EV infections during the first trimester were associated with beta cell autoantibodies in mothers of children who developed islet autoantibodies before 7 years of age. MATERIALS AND METHODS: Local registries were used to identify mothers to children born 2000-2007 who developed either beta cell autoantibodies or T1D during follow up...

Mucosal antibodies constitute the first line of adaptive immune defence against invaders in the female genital tract (FGT), yet the sequence of events leading to their production is surprisingly poorly characterized. We explored the induction of pathogen-specific antibody-secreting cells (ASC) as a response to an acute infection in the upper FGT. We recruited 12 patients undergoing surgery due to an upper FGT infection (7/12 blood culture positive, 5/12 negative) and six healthy controls. Pathogens were sampled during surgery and PBMC collected in the acute phase of the disease (days 7-10)...

The polybacterial invasion of the amniotic cavity and risk of preterm birth is often due to cervicovaginal bacteria such as genital mycoplasmas (Mycoplasma hominis and Ureaplasma urealyticum) and Gardnerella vaginalis. The most studied biomarker associated with preterm birth is interleukin-6 (IL-6), a pleiotropic cytokine that performs different functions based on classical or trans-signaling mechanisms. This study evaluated the changes in IL-6 and IL-6 function associated accessory molecules by human fetal membranes to determine the functional availability of IL-6 assessment in an in vitro model of polybacterial infection...

To prospectively study systemic in vivo immunological effects of sex hormones, using different phases of oral combined hormonal contraceptives (CHC), and the natural menstrual cycles in both healthy women and in women with multiple sclerosis (MS), blood samples from sixty female MS patients and healthy controls with and without CHC were drawn in high and low estrogenic/progestogenic phases. Expression of Th-associated genes in blood cells was determined by qPCR and a panel of cytokines and chemokines was measured in plasma...

HLA-G expressed by trophoblasts at the fetal-maternal interface and its soluble form have immunomodulatory effects. HLA-G expression depends on the combination of DNA polymorphisms. We hypothesized that combinations of specific single nucleotide polymorphisms (SNPs) in the 3'untranslated region (3'UTR) of HLA-G play a role in unexplained recurrent miscarriage. In a case control design, 100 cases with at least three unexplained consecutive miscarriages prior to the 20th week of gestation were included. Cases were at time of the third miscarriage younger than 36 years, and they conceived all their pregnancies from the same partner...

Previous studies have reported a preponderance of autoimmune thyroiditis (AIT) in females, but the detailed mechanisms have not been elucidated. In this study, we explored the effects of oestrogen on experimental AIT (EAT) and its potential mechanisms in an ovariectomised mouse model through the supplementation of high (equivalent to the level during pregnancy) or low (equivalent to the level at the oestrus stage) doses of oestradiol (E2). We found that EAT incidence, the intrathyroidal inflammatory score, serum anti-thyroglobulin IgG2b levels, splenic mRNA expression of Th1- and Th17-specific transcription factors and typical cytokines and the proportion of IL-12-producing dendritic cells were significantly increased in EAT mice treated with low-dose E2 compared with those in the control group...

The aim of this study was to evaluate Treg and NK cells related cytokines in deep infiltrating endometriosis lesions and its relationship with clinical symptoms of the disease. mRNA expression of Transforming Growth Factor Beta (TGFB), Interleukin (IL)10, Interferon Gamma (IFNG), IL7, and IL15 was analyzed by Real-Time PCR in eutopic endometrium and rectosigmoid lesions from 11 women with deep infiltrating endometriosis and in eutopic endometrium from 11 healthy women. IL10, IFNG, and IL7 expression was significantly higher in endometriotic bowel lesions than in eutopic endometrium from women with endometriosis...

Congenital Cytomegalovirus infection (cCMV) is the most common cause of congenital infections worldwide causing permanent long-term impairment (LTI). cCMV immunopathogenesis remains largely unknown due to the complex interplay between viral, maternal, placental and child factors. The aim of this study was to determine the possible role of particular HLA antigens, of the number of HLA mismatches (mm) and non-inherited maternal antigens (NIMAs) in a large retrospective nation-wide cohort of children with cCMV and their mothers...

Disturbances in fetal neurodevelopment have extensively been related to neurodevelopmental disorders in early and later life. Fetal neurodevelopment is dependent on adequate functioning of the fetal immune system. During pregnancy, the maternal immune system is challenged to both tolerate the semi-allogenic fetus and to protect the mother and fetus from microbes. The fetal immune system is influenced by maternal immune disturbances; therefore, perturbations in maternal immunity likely do not only alter pregnancy outcome but also alter fetal neurodevelopment...

Despite increasing evidence that epididymal immune disorders can lead to infertility, the cells and mechanisms underlying epididymal immunity remain poorly understood. In this study, we propose a rather exhaustive overview of innate and adaptive immune cells present in the murine caput and cauda epididymis. Using flow cytometry and a wide set of markers, we screened the broadest panel of immune cells ever, in this organ. For the first time, we unequivocally quantified the innate populations of monocytes, macrophages, and dendritic cells subtypes...

OBJECTIVES: Perturbation of the choriodecidual space before the onset of spontaneous preterm birth (sPTB) could lead to a concomitant rise in both cervicovaginal fluid (CVF) cytokine and fetal fibronectin (FFN), and assessing the concentrations of both markers could improve the prediction of sPTB (delivery before 37 completed weeks of gestation). Therefore, we prospectively determined mid-trimester changes in CVF cytokine and FFN concentrations, and their predictive capacity for sPTB in asymptomatic pregnant women...

The central role of inflammatory processes in labour and delivery is now well-recognised. However, the biomolecular, immunological and endocrine mechanisms involved in the labour process, and the clinical manifestations of inflammation in pregnancy, are complex, variable and modulated by factors such as aetiology, ethnicity and gestational age. In this review, evidence is presented of the pivotal relationship between progesterone and inflammation in pregnancy in terms of determining the timing of labour and delivery...

Cytokines in the reproductive tract environment at conception mediate a dialogue between the embryo and maternal tissues to profoundly influence embryo development and implantation success. Through effects on gene expression and the cell stress response, cytokines elicit an epigenetic impact with consequences for placental development and fetal growth, which in turn affect metabolic phenotype and long-term health of offspring. There is substantial evidence demonstrating that pro-survival cytokines, such as GM-CSF, CSF1, LIF, HB-EGF and IGFII, support embryos to develop optimally...

Polybrominated diphenyl ethers (PBDEs) are pollutants that may increase the risk of preterm birth. In previous studies, we found that a mixture of PBDEs altered the expression of biomarkers for preterm birth by the placenta. However, there are 209 different PBDE congeners with different tissue distributions. How these different congeners may alter the production of immunomodulators by the placenta that help to maintain the survival of the fetal allograft is unclear. Therefore, we compared the effects 5 common congeners on basal and bacteria-stimulated cytokine production by the placenta...
