Endometriosis is a chronic, inflammatory, condition of high incidence and serious reproductive and general health consequences. Understanding the pathogenesis of endometriosis is crucial for proper diagnostic and ordering the most effective treatment. Even though there is a large body of data regarding this pathology our understanding of the pathogenesis of this disease remains incomplete. The aim of this review is to summarize contemporary data regarding pathogenesis of endometriosis. Current data regarding endometrial origin, metaplastic and Mullerian embryonic rests theory will be reviewed here...

BACKGROUND: Endometriosis is a disease that affects 7-10% of reproductive-age women. When its diagnosis is delayed, its management becomes more difficult. Both for earlier detection and for therapeutic follow-up, discovering noninvasive biological markers with good specificity for this disease is a promising aspect of its research. We analyzed the recent data in the literature regarding these markers to determine which were worth following. MATERIALS AND METHODS: This literature review focused on medical data reported in the last 6 years (2011-2016)...

Endometrial mesenchymal stromal cells (eMSCs), along with mesenchymal stromal cells (MSCs) isolated from other tissues, are promising for use in regenerative medicine. The benefits of eMSCs include their presence in adults, simplicity of isolation, high proliferative and differentiation capacity. In this study, we have employed the flow cytometry technique to assess expression of 28 molecular markers on the surface of two eMSCs cultures. The culture of MSCs isolated from Wharton's jelly of the umbilical cord (uMSCs) was used as a reference, because uMSCs were studied in details earlier and demonstrated their effectiveness in vivo...

Subfertility in mares is mainly caused by endometrial diseases. Alterations of Toll-like receptors (TLRs) are associated with endometrial disorders in women. This study investigated TLRs 2, 4 and 6 in the equine endometrium. Endometria of 21 mares were examined by histology, PCR and immunohistochemistry. Tissues from 2 mares were considered normal. The remaining showed endometritis, endometrosis and/or angiosclerosis. TLRs 2, 4 and 6 were expressed as transcripts and proteins in all endometria. Immunohistochemistry detected TLRs 2, 4 and 6 in mast cells, luminal and glandular epithelial cells, stromal cells, endothelia, vascular smooth muscle and/or inflammatory cells...

When trying to conceive 1% of couples have recurrent miscarriages, defined as three or more consecutive pregnancy losses. This is not accounted for by the known incidence of chromosomal aneuploidy in miscarriage, and it has been suggested that there is an immunological aetiology. The endometrial mucosa is populated by a variety of immune cells which in addition to providing host pathogen immunity must facilitate pregnancy. Here we characterise the endometrial CD8-T cell population during the embryonic window of implantation and find that the majority of cells are tissue resident memory T cells with high levels of CD69 and CD103 expression, proteins that prevent cells egress...

The endometrium is the inner lining of the uterus. Following specific cyclic hormonal stimulation, endometrial stromal fibroblasts (stroma) and vascular endothelial cells exhibit morphological and biochemical changes to support embryo implantation and regulate vascular function, respectively. Herein, we integrated a resin-based porous membrane in a dual chamber microfluidic device in polydimethylsiloxane that allows long term in vitro co-culture of human endometrial stromal and endothelial cells. This transparent, 2-μm porous membrane separates the two chambers, allows for the diffusion of small molecules and enables high resolution bright field and fluorescent imaging...

Depot-medroxyprogesterone acetate is a commonly used injectable contraceptive that has been associated with an increased risk of HIV acquisition. This study compares effects of depot-medroxyprogesterone acetate on immune parameters from several upper reproductive tract compartments relevant to HIV-1 susceptibility in repetitive samples from 15 depot-medroxyprogesterone acetate users and 27 women not on hormonal contraceptives. Compared with samples from unexposed women in the mid-luteal phase, depot-medroxyprogesterone acetate use was associated with: increased endocervical concentrations of MCP1 and IFNalpha2; decreased endocervical concentrations of IL1beta and IL6; increased proportions of endometrial CD4+ and CD8+ cells expressing the activation marker HLADR; increased density of endometrial macrophages; and decreased density of endometrial regulatory T cells...

BACKGROUND: Embryo implantation remains the main limiting factor in IVF/ICSI program. Endometrial immune remodeling events begin before implantation and are a vital process for pregnancy, preparing future maternal immune tolerance and regulating the placentation process. METHODS: Between 2012 and 2014, 193 patients (analyzed group) enrolled in our IVF program benefitted of an endometrial immune profiling to determine if their uterus was immunologically ready to accept an embryo and, if not, the specific immune mechanisms involved...

Variety of neurodegenerative diseases in humans are caused by loss of cells along with loss of function and disability. Cell replacement therapy is a potential strategy to cure neurodegenerative diseases. Mesenchymal stem cells are pluripotent non-hematopoietic cells that can be isolated from numerous tissues. Human endometrial-derived stem cell (hEnSC) are the abundant and easy available source with no immunological response, for cell replacement therapy. In the nervous system, where fatty acids are found in huge amounts, they participate in its development and maintenance throughout life...

INTRODUCTION: Recent reports consider endometriosis to be an immunological disorder, thus suggesting potential efficacy of immunomodulators for its treatment. The aim of this study was to assess the effects of oral administration of pentoxifylline on endometriosis-like lesions in a heterologous mice model. STUDY DESIGN: Human endometrial tissue obtained from women (n = 5) undergoing surgery for benign conditions was implanted in nude female mice (n = 30). The animals were distributed into 3 experimental groups receiving: saline 0...

CONTEXT: Angiogenesis is required for ectopic endometrial tissue growth. Our previous studies showed that prostaglandin F2α (PGF2α) biosynthetic enzymes and receptor were markedly elevated in endometriotic lesions and that PGF2α is a potent angiogenic factor in endothelial cells. OBJECTIVE: We sought to determine whether or not the F-prostanoid receptor modulates angiogenesis in ectopic stromal cells. DESIGN: Release of angiogenic factors by ectopic endometrial stromal cell primary cultures stimulated with PGF2αand exposed to agents that target PGF2α signaling was assessed...

BACKGROUND: Preeclampsia (PE) is a major cause of maternal and neonatal morbidity and mortality. Epidemiological association between Helicobacter pylori (Hp) infection and PE onset has been widely shown. The aim of this study was to analyze a possible correlation between Hp infection and the severity of clinical presentation of PE and to identify an immunologic mechanism triggered by Hp infection potentially contributing to the pathogenesis of PE. MATERIALS AND METHODS: Sera from 93 preeclamptic women and 87 healthy pregnant women were tested for Hp infection by immunoassay and for anti-CagA antibodies by Western blot assay...

BACKGROUND: Massive chromosomal aberrations are a signature of advanced cancer, although the factors promoting the pervasive incidence of these copy number alterations (CNAs) are poorly understood. Gatekeeper mutations, such as p53, contribute to aneuploidy, yet p53 mutant tumors do not always display CNAs. Uterine Corpus Endometrial Carcinoma (UCEC) offers a unique system to begin to evaluate why some cancers acquire high CNAs while others evolve another route to oncogenesis, since about half of p53 mutant UCEC tumors have a relatively flat CNA landscape and half have 20-90% of their genome altered in copy number...

INTRODUCTION: Leiomyosarcoma is a rare gynecologic malignancy that accounts for less than 1% of gynecological malignancies. Leiomyosarcoma of the broad ligament is an even rarer condition. According to Gardner's criteria, the diagnosis is made when the mass is completely separated from the uterus and adnexa. So far, 23 cases of primary leiomyosarcoma of the broad ligament have been reported in the literature published in English. CASE PRESENTATION: In September 2014, a 55-year-old, gravida 3, para 3 woman with a BMI of 30 and a chief complaint of fever and dizziness was admitted to the infectious-diseases ward of the Pars general hospital affiliated with Iran University of Medical Sciences in Tehran, Iran...

In healthy women, intra- and extracellular controls prevent the attachment and proliferation of ectopic endometrial cells. During endometriosis, abnormalities in these control mechanisms permit the survival of endometrial cells, their subsequent attachment to the peritoneal cavity, and disease progression. These abnormal cells cause invasion of tissues and induce an inflammatory response. Several genetic, immunological, and environmental factors contribute to this complex process. In this study we examined 6 polymorphisms for 6 different genes (p53; estrogen receptor β; progesterone receptor; GSTM1; GSTT1; CYP1A1)...

Uterine natural killer (NK) cells are abundantly present in endometrium and decidua. Their function is governed by interactions between killer cell immunoglobulin-like receptors (KIRs) and cognate human leukocyte antigen (HLA) class I ligands. These interactions have implications for reproductive success. Whereas most uterine NK cells are known to express KIRs, little information is available about KIR repertoire formation and stability over time. This is primarily due to inherent difficulties in gaining access to human uterine tissue...

INTRODUCTION: Endometriosis is a multifactorial benign gynecologic disorder, characterized by the ectopic growth of misplaced endometrial cells with complex genetic inheritance and changing of some immune based factors and also shares some autoimmune characteristics. However, it is not clear yet that how and when these immunological factors affect the initiation or progression of the disease. It has been shown that STAT4 is a predisposing gene in the development of some autoimmune diseases...
