Pregnancy is an immune challenge to the maternal immune system. The effects of pregnancy on maternal immunity and particularly on memory T cells during and after pregnancy are not fully known. This observational study aims to show the short term and the long term effects of pregnancy on the constitution, size and activation status of peripheral human memory T-lymphocyte populations. Effector memory (EM) and central memory (CM) T-lymphocytes were analyzed using flow cytometry of peripheral blood from 14 nulligravid, 12 primigravid and 15 parous women that were on average 18 months postpartum...

Peripheral and uterine NK cells (pNK, uNK) can be distinguished according to their receptor expression. Recent studies indicate an association of elevated pNK and uNK with recurrent miscarriage (RM). This study aimed to analyze pNK and uNK in patients with RM and healthy controls. Out of n=590 RM patients screened according to a standard diagnostic protocol, n=268 couples with ≥3 consecutive RM were identified. Subgroups consisted of n=151 primary RM (pRM), n=85 secondary RM (sRM), n=32 tertiary RM (tRM) and n=42 healthy controls...

Proteins of the epididymal and testicular mileu contribute to sperm maturation and a vast majority of them remain uncharacterised. In this study, the role of three Lysozyme-like (LYZL) proteins, namely LYZL1, LYZL4 and LYZL6 in sperm function was assessed using in vitro neutralization and auto antibodies generation model. Rats immunized with LYZL1, LYZL4 and LYZL6 proteins had a litter size of 5.93, 8.47 and 2.10 respectively compared to 9.96 in the control rats. The litter size was further reduced to 4.53, 7...

Successful pregnancy relies on the accurate regulation of the maternal-fetal immune system. Without enough tolerance in the uterine microenvironment, the mother and the hemiallogeneic fetus could not peacefully coexist. T cell immunoglobulin and mucin domain (Tim)-3 is a molecule originally regarded as to be expressed on terminally differentiated IFN-γ expressing CD4(+) T cells (Th1). The engagement of Tim-3 with its ligand, galectin-9 (Gal-9) could induce the exhaustion or apoptosis of effector T cells, and thus might regulate the tolerance...

Preterm delivery (PTD) is one of the potent contributor of neonatal mortality and morbidity, and the underlying cause in some situation is elusive. This study attempts to delineate the association of deregulation in progesterone receptor (PR) pathway and deleterious immune responses in predisposing patients to PTD in Northeast India, a region with high rate of PTD cases. A total of 109 cases of PTD and 100 term delivery cases were enrolled with all clinical details. The PTD cases were stratified based on gestation age at delivery...

Chronic prostatitis is a risk factor for impaired male fertility potential, and anti-sperm antibodies (ASAs) cause the autoimmune disease immune infertility, which has a negative effect on semen parameters. Current studies have investigated the ASA-positive relationship between chronic prostatitis versus normal controls, but have shown inconsistent results. Hence, we systematic searched the PubMed, EMBASE, Science Direct/Elsevier, Medline, and the Cochrane Library up to October 2015 for case-control studies that involved the ASA-positive relationship between chronic prostatitis patients versus normal controls...

Alterations in normal balance of B cell subsets have been reported in various rheumatic diseases. In this study, we report a woman with a history of recurrent pregnancy losses (RPL) and infertility who had low levels of memory B cells. A 35-year-old woman with a history of RPL and infertility was demonstrated to have increased peripheral blood CD19+ B cells with persistently low levels of memory B cell subsets. Prior to the frozen donor egg transfer cycle, prednisone and intravenous immunoglobulin G (IVIg) treatment was initiated and patient achieved dichorionic diamniotic twin pregnancies...

The pathologies of the dangerous pregnancy complications pre-eclampsia (PE) and fetal growth restriction (FGR) are established in the first trimester of human pregnancy yet we know little of how this happens. Finely tuned interactions between maternal and placental cells are essential for pregnancy to progress without complications; however, the precise nature of this cross-talk and how it can go wrong are crucial questions that remain to be answered. This review summarises recent studies examining the role played by natural killer cells in regulating normal placentation and remodelling...

Complement component C1q is one of the recognition molecules of the complement system which can serve several functions unrelated to complement activation. This molecule is produced at foeto-maternal interface by macrophages as wells as by decidual endothelial cells and invading trophoblast. Foetal trophoblast cells migrating through the decidua in the early stages of pregnancy synthesize and express C1q on their surface, which is actively involved in promoting trophoblast endovascular and interstitial invasion of the decidua...

: Studies have shown that not only bacterial vaginosis, but also intermediate vaginal flora has deleterious effects for women's reproductive health. However, literature still lacks information about microbiological and immunological aspects of intermediate flora. OBJECTIVE: To characterize intermediate flora regarding levels of Interleukin (IL)-1beta, IL-6, IL-8, tumor necrosis factor-alpha, interleukin 1 receptor antagonist (IL-1ra), IL-10, sialidase; loads of Gardnerella vaginalis, total bacteria and to verify whether it is closer related to normal flora or bacterial vaginosis...

Chemokines were known to participate in inflammation and angiogenesis but have been recently recognized to be involved in embryonic implantation and endometrium-related pathologies. Among these chemokines, the CXC chemokines, such as CXCL1, have potential roles to work as biomarkers to identify patients with uterine adenomyosis. In this study, human endometrial epithelial cells (HEECs) were derived from patients' endometrium with adenomyosis. The inductive effects of CXCL1 production by various mediators/growth factors were investigated in the HEECs...

PURPOSE: Idiopathic Asthenozoospermia (AZS) is a common symptom of male infertility described as reduced forward motility or absence of sperm motility. The PATE1 is generally expressed in male genital tract and related to sperm development, maturation and fertilization. However, the single nucleotide polymorphisms (SNPs) of the PATE1 gene which contribute to AZS were still unknown. For this reason, the possible association between the single nucleotide polymorphisms of the PATE1 gene and idiopathic asthenozoospermia was investigated in this research...

Systemic lupus erythematosus (SLE) is an auto-immune systemic disease showing a strong predilection for women of reproductive age. Higher prevalance of SLE among young women are in part accounted for by the effects of estrogen hormone on immune system. The key pathophysiological features of this disease are the generation of autoantibodies and the deposition of antibody-antigen complexes in the basal membranes of the organs where they evoke inflammatory responses and injury. Young females diagnosed with SLE are more prone to developing a multitude of adverse reproductive and obstetric outcomes, especially in the presence of active disease...

PROBLEM: Reproductive failure including RM has been suggested to correlate with antibodies that cross react with HLA-negative syncytiotrophoblasts and we have reported that 17% of women with 2 or more miscarriages and 34% of women with 3 or more miscarriages express anti-trophoblast antibodies (ATAB). Until now, the mechanism, how ATAB interfere with pregnancy success is not known. HCG and progesterone both play fundamental roles in supporting human pregnancy. Therefore we investigated the effects of sera of RM patients containing ATAB on the hCG and progesterone production of cells of the choriocarcinoma cell line JEG-3...

It has been proposed that the transforming growth factor (TGF)-β1 present in seminal plasma (SP) triggers a female immune response favorable for implantation. We hypothesize that seminal interleukin (IL)-18, a cytokine that can potentially cause implantation failure, interferes with the beneficial effect of TGF-β1. This study aims to determine whether the levels of seminal TGF-β1 and IL-18 are associated with reproductive outcomes in patients exposed to SP during in vitro fertilization (IVF) or IVF with intracytoplasmic sperm injection (ICSI)...
