The objective of this study was to determine whether there are any differences in the T cell composition and the expression of specific factors (i.e., IRF4, TBX21, GATA3, and GITR) of T cells between women with Repeated Implantation Failure (RIF) and fertile women. We observed a decrease in circulating Tregs and exhausted CD8 + T cells in RIF patients when compared to the controls whereas exhausted Treg and Th17 cells were more frequent. Using real-time PCR, we determined that the expression of IRF-4 and TBX21 was significantly elevated in the cases...

The aim of the present study was to characterize the lysozyme concentration and the bacterial killing activity (BKA) of boar seminal plasma against E. coli and S. aureus in 119 fertile Pietrain boars (aged: 18.1 ± 10.5 months). Lysozyme concentration was 2.4 ± 1.2 μg/ml in seminal plasma. More than 80% of the samples (97 of 119) showed BKA against E. coli or S. aureus or both bacterial strains: Group 1 (BKA against E. coli and S. aureus, n = 38), Group 2 (BKA against E. coli, n = 13), Group 3 (BKA against S...

INTRODUCTION: immature-myeloid cells (IMCs) are proangiogenic bone marrow (BM)-derived cells that normally differentiate into inflammatory cells such as neutrophils, monocytes and dendritic cells (DCs). We characterized placental IMCs comparing their gene expression and subpopulations to tumor IMCs, and tested our hypothesis that progesterone that inhibits preterm labor, may affect their abundance and differentiation. METHODS: differences between IMC-subpopulations in subcutaneous tumors versus placentas in C57BL/6 or ICR (CD-1) mice were analyzed by flow cytometry and gene expression was detected by microarrays...

This retrospective study of prospectively collected data examines the effect of prednisolone therapy on raised uterine Natural Killer cell (uNK) concentrations and pregnancy outcomes in women with recurrent miscarriage (RM) and recurrent implantation failure (RIF) after IVF/ICSI treatment. 136 women diagnosed with RRF who had a timed midluteal endometrial biopsy taken for uNK cell analysis were included. Women with high uNK cell concentrations (n = 45) were treated with prednisolone (10 mg/day) for one month, after which a second biopsy was taken for repeat uNK cell analysis...

PROBLEM: Continuous failures to achieve a pregnancy despite effective embryo transfers is extremely distressing for couples. In consequence, many adjuvant therapies to IVF have been proposed to achieve an "ideal" immune environment. We here focus on Intralipid® therapy (IL) reported to have immunosuppressive properties on NK cells. METHOD OF STUDY: 94 patients exhibited an immune profile of endometrial over-immune activation and an history of repeated implantation failures despite multiple embryos transfers (RIF)...

Though human pregnancy success has been classically linked with a shift into a Th2 immunoglobulin producing cell response, a clear picture concerning B cell development and immunoglobulin profile during human pregnancy is missing. We analyzed in this work the dynamic of different B cell populations in peripheral blood of pregnant women on the first, second and third trimester of pregnancy. As control, age-matched non-pregnant fertile women were included. Additionally, we quantified the levels of immunoglobulin (IgG1, IgG2, IgG3, IgG4, IgM, IgA and IgE) in the serum of pregnant and non-pregnant women...

Obesity is associated with implantation failure, miscarriage, low-grade inflammation and a reduction in peripheral immune-suppressive T regulatory (Treg) cells. Therefore, we postulated that this reduction may also extend to the endometrium and cause embryonic loss. In a cohort of 40 infertile women, without implantation failure or recurrent miscarriage, we examined the density of Treg cells, macrophages and natural killer (NK) cells in mid-luteal endometrial biopsies. Significant positive correlations were observed between BMI and endometrial Treg cells and macrophages, but no relationship with NK cells...

To characterize Annexin A1 (ANXA1), FPR2/ALX and cytokines expression in peritoneal endometriosis and to clarify their role in its etiology, a cross-sectional study was performed with forty women in reproductive age (22 patients with endometriosis and 18 control women) that had undergone laparoscopic surgery. Peritoneal biopsy and fluid aspirations from endometriosis and control samples were analyzed for the expression of ANXA1, FPR2/ALX and cytokines. ANXA1 and FPR2 / ALX levels were measured by Western blotting and interleukin 1ß (IL-1β), interleukin 4 (IL-4), interleukin 6 (IL-6), and interleukin 10 (IL-10) levels were quantified by enzyme-linked immunosorbent assay (ELISA)...

The detrimental consequences of obesity on female fertility are well known, but the functional changes that occur in the ovary in response to elevated BMI are not clear. Obesity induces multiple components of a systemic inflammatory state that is a key pathway by which it initiates tissue dysfunction in adipose, liver and muscle; however whether obesity induces similar inflammatory changes in the ovary has not been fully investigated. This is important to understand because it is increasingly clear that obesity at conception impacts not only pregnancy rates but also influences pre-implantation embryo development...

Sexually transmitted infections (STI) can have major consequences for the reproductive health of women. Mycoplasma genitalium is a STI that is not as well studied but causes pelvic inflammatory disease (PID) among other complications. Another well-known STI is Chlamydia trachomatis, notorious for its capability to cause infertility. Both C. trachomatis and M. genitalium share some of the same clinical aspects. Parts of the pathogenesis of C. trachomatis and M. genitalium infections are unclear but potential factors are the microbiome and other STIs...

Polycystic ovary syndrome (PCOS) affects the endocrine system and is associated with low-grade inflammation. Natural killer (NK) cells are involved in the defense of the female reproductive tract, folliculogenesis, ovulation and the menstrual cycle. The killer-cell immunoglobulin-like receptors (KIR) on the surface of NK cells modulate the activation and function of these cells after interacting with human leukocyte antigen (HLA) class I ligands. The objective of this study was to evaluate the possible association of the KIR and their HLA ligands with polycystic ovary syndrome...

During pregnancy the maternal immune system has to develop tolerance towards the developing fetus. These changes in maternal immunity can result in increased severity of certain infections, but also in amelioration of autoimmune diseases. Pregnancy-related hormones have been suggested to play a central role in the adaptation of the maternal immune system, but their specific effects on innate immune function is not well understood. In a longitudinal study of pregnant women, we investigated innate immune cell function in response to toll-like receptors (TLR) 4 and 7 stimulation, two TLR pathways playing a critical role in early innate immune recognition of bacteria and viruses...

BACKGROUND: Uteroplacental acute atherosis is a pregnancy-specific lesion resembling early stages of atherosclerosis found frequently in preeclampsia. Preeclampsia is associated with an increased risk for future maternal atherosclerotic cardiovascular disease. The renin-angiotensin-system plays a role both in atherosclerosis and in preeclampsia. Circulating agonistic autoantibodies at the angiotensin-II type 1 receptor (AT1 -AA) are increased in preeclampsia. We hypothesized an association between AT1 -AA at delivery and postpartum with acute atherosis in pregnancy...

Pregnant women experience more sleep disturbances and greater systemic inflammation than non-pregnant women. However, the few studies that have examined the links between sleep and inflammation in pregnant women have been in clinical samples. We examined whether sleep duration is associated with C-reactive protein (CRP) levels, a marker of inflammation, in pregnant and non-pregnant women in a population-based sample of US women. Participants were 2865 women of reproductive age (aged 20-44 years) in the National Health and Nutrition Examination Survey (NHANES), a nationally representative sample of Americans...

This study aims to determine if a short duration of sexual relationship is more common among women who experience adverse pregnancy outcomes including gestational hypertension (GHT), preeclampsia, small for gestational age (SGA) pregnancies and spontaneous preterm birth (sPTB) with or without abnormal uterine artery Doppler compared to women who have uncomplicated pregnancies. 5591 nulliparous women from the Screening for Pregnancy Endpoints (SCOPE) study were included. The risk for pregnancy complications for women who had a duration of sexual relationship of ≤3 months, 4-6 months, 7-9 months, 10-12 months was compared with women who had a duration of sexual relationship of >12 months...

The studies proposed here were undertaken to test the hypothesis that, under specific circumstances (e.g., a strong enough inflammatory stimulus), genes that are repressed at the maternal-fetal interface via DNA methylation might be de-methylated, allowing either a maternal immune response to the semi-allogenic fetus or the onset of early labor. Chorionic trophoblasts (CT) were isolated from fetal membranes, followed by incubation with medium from LPS-activated PBMC or resting PBMC medium for 2 h. RNA and DNA were isolated from the cells for RNA-seq and DNA methylation studies...

Endometriosis is a prevalent gynaecological disorder with a still unclear pathogenesis. So far inflammatory mechanisms are associated with disease progression and critical reviews have discussed the so-called 'danger theory' related to endometriosis. Hence, we performed immunoassays to evaluate whether local inflammation is linked to the severity of the disease. In addition, we investigated the role of recently described cytokines IL-33, IL-32α and the 'alarmin' high mobility group box 1 (HMGB1). We confirmed a dysfunctional immune response in the local environment of women suffering from endometriosis...
