The hormone-responsive glandular layer of ENDOMETRIUM that sloughs off at each menstrual flow (decidua menstrualis) or at the termination of pregnancy. During pregnancy, the thickest part of the decidua forms the maternal portion of the PLACENTA, thus named decidua placentalis. The thin portion of the decidua covering the rest of the embryo is the decidua capsularis.
The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.
Cells lining the outside of the BLASTOCYST. After binding to the ENDOMETRIUM, trophoblasts develop into two distinct layers, an inner layer of mononuclear cytotrophoblasts and an outer layer of continuous multinuclear cytoplasm, the syncytiotrophoblasts, which form the early fetal-maternal interface (PLACENTA).
A highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products. It includes a fetal portion (CHORIONIC VILLI) derived from TROPHOBLASTS and a maternal portion (DECIDUA) derived from the uterine ENDOMETRIUM. The placenta produces an array of steroid, protein and peptide hormones (PLACENTAL HORMONES).
The thin layers of tissue that surround the developing embryo. There are four extra-embryonic membranes commonly found in VERTEBRATES, such as REPTILES; BIRDS; and MAMMALS. They are the YOLK SAC, the ALLANTOIS, the AMNION, and the CHORION. These membranes provide protection and means to transport nutrients and wastes.

The development of the PLACENTA, a highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products between mother and FETUS. The process begins at FERTILIZATION, through the development of CYTOTROPHOBLASTS and SYNCYTIOTROPHOBLASTS, the formation of CHORIONIC VILLI, to the progressive increase in BLOOD VESSELS to support the growing fetus.
The hollow thick-walled muscular organ in the female PELVIS. It consists of the fundus (the body) which is the site of EMBRYO IMPLANTATION and FETAL DEVELOPMENT. Beyond the isthmus at the perineal end of fundus, is CERVIX UTERI (the neck) opening into VAGINA. Beyond the isthmi at the upper abdominal end of fundus, are the FALLOPIAN TUBES.
The threadlike, vascular projections of the chorion. Chorionic villi may be free or embedded within the DECIDUA forming the site for exchange of substances between fetal and maternal blood (PLACENTA).
The outermost extra-embryonic membrane surrounding the developing embryo. In REPTILES and BIRDS, it adheres to the shell and allows exchange of gases between the egg and its environment. In MAMMALS, the chorion evolves into the fetal contribution of the PLACENTA.
The mucous membrane lining of the uterine cavity that is hormonally responsive during the MENSTRUAL CYCLE and PREGNANCY. The endometrium undergoes cyclic changes that characterize MENSTRUATION. After successful FERTILIZATION, it serves to sustain the developing embryo.
Endometrial implantation of EMBRYO, MAMMALIAN at the BLASTOCYST stage.
The innermost membranous sac that surrounds and protects the developing embryo which is bathed in the AMNIOTIC FLUID. Amnion cells are secretory EPITHELIAL CELLS and contribute to the amniotic fluid.
The most common (>96%) type of ectopic pregnancy in which the extrauterine EMBRYO IMPLANTATION occurs in the FALLOPIAN TUBE, usually in the ampullary region where FERTILIZATION takes place.
Collection of granular epithelial cells in the uterine muscle beneath the placenta that develop during pregnancy in certain species of animals.
The repetitive uterine contraction during childbirth which is associated with the progressive dilation of the uterine cervix (CERVIX UTERI). Successful labor results in the expulsion of the FETUS and PLACENTA. Obstetric labor can be spontaneous or induced (LABOR, INDUCED).
Expulsion of the product of FERTILIZATION before completing the term of GESTATION and without deliberate interference.
Proteins produced by organs of the mother or the PLACENTA during PREGNANCY. These proteins may be pregnancy-specific (present only during pregnancy) or pregnancy-associated (present during pregnancy or under other conditions such as hormone therapy or certain malignancies.)
A hypothalamic hormone that is synthesized as a precursor protein which is cleaved into two peptides. In addition to stimulating PROLACTIN release the peptides bind to specific G-PROTEIN-COUPLED RECEPTORS found at locations within the BRAIN.
The last third of a human PREGNANCY, from the beginning of the 29th through the 42nd completed week (197 to 294 days) of gestation.
An acyclic state that resembles PREGNANCY in that there is no ovarian cycle, ESTROUS CYCLE, or MENSTRUAL CYCLE. Unlike pregnancy, there is no EMBRYO IMPLANTATION. Pseudopregnancy can be experimentally induced to form DECIDUOMA in the UTERUS.
The process of bearing developing young (EMBRYOS or FETUSES) in utero in non-human mammals, beginning from FERTILIZATION to BIRTH.
The disintegration and assimilation of the dead FETUS in the UTERUS at any stage after the completion of organogenesis which, in humans, is after the 9th week of GESTATION. It does not include embryo resorption (see EMBRYO LOSS).
The age of the conceptus, beginning from the time of FERTILIZATION. In clinical obstetrics, the gestational age is often estimated as the time from the last day of the last MENSTRUATION which is about 2 weeks before OVULATION and fertilization.

The period from onset of one menstrual bleeding (MENSTRUATION) to the next in an ovulating woman or female primate. The menstrual cycle is regulated by endocrine interactions of the HYPOTHALAMUS; the PITUITARY GLAND; the ovaries; and the genital tract. The menstrual cycle is divided by OVULATION into two phases. Based on the endocrine status of the OVARY, there is a FOLLICULAR PHASE and a LUTEAL PHASE. Based on the response in the ENDOMETRIUM, the menstrual cycle is divided into a proliferative and a secretory phase.
A low affinity interleukin-11 receptor subunit that combines with the CYTOKINE RECEPTOR GP130 to form a high affinity receptor for INTERLEUKIN-11. Multiple isoforms of this protein exist due to ALTERNATIVE SPLICING of its MRNA.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

The HLA-G antigens are considered non-classical class I antigens due to their distinct tissue distribution which differs from HLA-A; HLA-B; and HLA-C antigens. Note that several isoforms of HLA-G antigens result from alternative splicing of messenger RNAs produced from the HLA-G*01 allele.
Chemical substances that interrupt pregnancy after implantation.

Marker genes of decidualization: activation of the decidual prolactin gene. (1/1114)

Decidualization of human endometrial stromal (ES) cells in vitro is induced by cAMP analogues and ligands that elevate cellular cAMP levels in a manner resembling the gonadotrophins, prostaglandin E2 and relaxin (RLX). This differentiation process is marked by the onset of decidual prolactin (PRL) production in the late luteal phase of the cycle. Using transfection assays and a primary ES cell culture system, we have demonstrated that decidual PRL gene transcription is driven by an alternative upstream promoter (dPRL), approximately 6 kb upstream of the pituitary transcription start site. In primary cell cultures, RLX not only acutely but also permanently elevated cellular cAMP levels and induced PRL secretion after 6 days. Northern and Western blot analyses revealed all regulatory subunit isoforms (RIalpha, RIbeta, RIIalpha, RIIbeta) and catalytic subunits Calpha and Cbeta of protein kinase A (PKA) in ES cells. Transcript levels of PKA subunit isoforms are not altered during decidualization, but in decidualized ES cells exposed to elevated cellular cAMP levels by stimulation with RLX for >6 days, RIalpha protein levels were significantly reduced, whereas levels of all other forms remained unchanged. Reducing the availability of R subunits changed the R:C subunit ratio in favour of C and increased kinase activity. In transient transfections of undifferentiated ES cells, the dPRL promoter was activated by 8-Br-cAMP and by C subunit (Cbeta) of PKA. This induction, and the differentiation-dependent activity of the dPRL promoter in transfected decidualized cells, was effectively abolished by the co-expression of protein kinase inhibitor (PKI). A fragment of 332 bp of 5'-flanking region of the dPRL transcription start site was sufficient to mediate full inducibility by cAMP. cAMP activation of the dPRL promoter in ES cells was biphasic as an initial weak induction within 12 hours was followed by a subsequent, much more intense induction after 12 hours. The secondary induction was not seen with a control construct driven by a consensus cAMP response element (CRE) linked to a minimal promoter. The early response of the dPRL promoter depended upon a non-palindromic CRE at position -12 and mutation of this sequence led to omission of the early, but not of the delayed, induction. The major activation of the dPRL promoter depended upon a different region between position -332 and -270 since its deletion significantly reduced inducibility by cAMP. Its action was probably indirect as its kinetics differed from classic CRE-mediated responses, and it was specific to ES cells.  (+info)

Ryk is expressed in a differentiation-specific manner in epithelial tissues and is strongly induced in decidualizing uterine stroma. (2/1114)

Ryk is a ubiquitously expressed tyrosine kinase-like receptor of unknown activity and associations. We examined ryk expression in adult mouse epithelial tissues and during embryonic development at the histological level. Ryk RNA is present at greatly increased levels in cells at particular stages of epithelial differentiation: the basal layer of skin and tongue epithelia, the intervillous layer and some crypt bases of the intestine and the lower matrix region of the hair follicle. Although ryk RNA is expressed at similar levels in a variety of tissues from embryonic day 10.5 to 18.5, specific induction of ryk RNA can be seen by in situ hybridization in the basal layer of skin and hair follicle at day 15.5-16.5, and protein staining localizes to the hair follicle by immunohistochemistry. At day 4.5 and 6.5, little if any ryk is present in the blastocyst, but it is transiently induced at a high level in mature decidual cells of the uterine stroma. We review a number of independent isolations of ryk, including fruit fly and nematode members of the ryk family. Because ryk is induced in epithelial cells seeking a final place in a differentiated tissue, or during remodeling of the endometrium, and a homologous gene, derailed, is known to regulate muscle and nerve target seeking in Drosophila, ryk may also be involved in cellular recognition of appropriate context.  (+info)

Cytosolic phospholipase A2 in rat decidual cells: evidence for its role in decidualization. (3/1114)

We investigated the existence and possible role of cytosolic phospholipase A2 (cPLA2) in rat decidualized uteri. PLA2 activity in the cytosol of a decidualized uterine horn, induced by intraluminal oil infusion, was significantly higher than that in contralateral intact horn. The activity was almost completely depressed by cPLA2 inhibitors including arachidonyl trifluoromethyl ketone (ATK). The immunoreactive signals for cPLA2 were intense in decidua and glandular epithelial cells. In vivo administration of ATK (0.1-100 microg) caused a dose-dependent inhibition of decidualization. These results show the presence of cPLA2 and its probable implication in decidualization in rat uterus.  (+info)

Prostaglandin endoperoxide H synthase mRNA expression in the human amnion and decidua during pregnancy and in the amnion at preterm labour. (4/1114)

We have examined the expression of prostaglandin endoperoxide H synthase (PGHS) isoenzymes in the amnion and the decidua during gestation, and the abundance of PGHS mRNA in the amnion at idiopathic preterm labour. PGHS-1 and -2 mRNA abundance in the amnion, determined with ribonuclease protection assays, was significantly (P< 0.05) higher at term than earlier during pregnancy. In contrast, neither PGHS-1 and -2 mRNA values, nor PGHS-specific activity, measured with a cell-free assay, was different in the decidua at term as compared to earlier gestational ages. In individual term patients, PGHS-2 mRNA values in the amnion were positively correlated with PGHS-2 mRNA values in the chorion laeve. PGHS-1 and -2 mRNA abundance was higher (P < 0.05) in the amnion after idiopathic preterm labour than in the absence of labour at the same gestational age (28-35 weeks). Thus, PGHS-1 and -2 are induced in the amnion at term. Furthermore, amniotic PGHS-2 changes in co-ordination with PGHS-2 concentrations in the chorion laeve. PGHS is not induced in the decidua at term. Increased amniotic PGHS expression may contribute to the enhanced intrauterine prostaglandin synthesis before term labour. Both PGHS isoenzymes may participate in the increase of PGHS activity in the amnion at preterm birth.  (+info)

Gestational regulation of granulocyte-colony stimulating factor receptor expression in the human placenta. (5/1114)

A number of cytokines and their receptors are abundantly expressed at the materno-fetal interface and are thought to have a function in the regulation of placentation. Granulocyte-colony stimulating factor (G-CSF) is expressed by stromal cells in both placental tissue and maternal decidua throughout placentation. In this study, we examined the expression of placental G-CSF receptor (G-CSFR) mRNA and protein throughout gestation by ribonuclease protection assays, Western blotting, and immunohistochemistry. The major placental form of G-CSFR mRNA, corresponding to a membrane-bound form of the protein, was present in first-trimester placental tissues; levels decreased in second- and were highest in third-trimester placental tissues. Two placental G-CSFR molecules, 120 kDa and 150 kDa, were detected in first- and third-, but not second-, trimester tissues. The level of the 150-kDa G-CSFR was greater in the third- than in first-trimester samples. These differences were irrespective of whether or not the patients had received prostaglandin E1 analogues, prostaglandin E1 analogues and oxytocin, oxytocin alone, or mifepristone before labor. We demonstrated by immunohistochemistry that interstitial cytotrophoblast in first- and second-trimester decidual tissue and cytotrophoblast in term fetal membranes express G-CSFR. These data demonstrate that the expression of specific forms of placental G-CSFR is strictly cell type- and developmental stage-specific, and they suggest that G-CSFR may be important in decidual invasion of cytotrophoblast and in trophoblast function during placentation.  (+info)

Spatiotemporal expression of cyclooxygenase 1 and cyclooxygenase 2 during delayed implantation and the periimplantation period in the Western spotted skunk. (6/1114)

Embryonic development in the western spotted skunk is arrested after blastocyst formation for about 200 days. This developmental arrest is believed to be due to insufficiency of uterine conditions to support continuous development. Implantation and decidualization are defective in cyclooxygenase 2 (Cox2)-, but not Cox1-, deficient mice. We therefore used Northern and in situ hybridization to investigate changes in uterine expression of Cox1 and Cox2 genes during various stages of pregnancy in the spotted skunk. Cox1 was constitutively expressed at all stages of pregnancy examined, but it did exhibit localized up-regulation in the trophoblast and necks of uterine glands at early implantation sites. Cox2 expression was highly regulated with little or no expression during delayed implantation. Cox2 expression was first detected in the uterus and trophoblast prior to blastocyst attachment and remained detectable for 5-6 days after blastocyst attachment. Cox2 expression was also localized in the luminal and glandular epithelia of uterine segments located between implantation chambers. Changes in Cox expression were not correlated with the abrupt increase in uterine weight that occurs simultaneously with renewed embryonic development but was correlated with an influx of serum proteins into the uterus observed in a previous study.  (+info)

Localization of ubiquitin and ubiquitin cross-reactive protein in human and baboon endometrium and decidua during the menstrual cycle and early pregnancy. (7/1114)

We have examined the distribution of ubiquitin and the related ubiquitin cross-reactive protein (UCRP) in paraffin-embedded sections of human and baboon endometrium and decidua by immunoperoxidase or immunofluorescence cytochemistry with antibodies raised against ubiquitin, UCRP, CD45, and insulin-like growth factor-binding protein-1. Anti-ubiquitin immunoreactivity was present in the nonpregnant endometrium, particularly in the glandular epithelial cells, and up-regulated in endometrial stromal cells as they decidualized at the beginning of pregnancy. Anti-UCRP immunoreactivity was absent from nonpregnant tissue but accumulated to high levels in decidual cells during pregnancy. Western blotting indicated that immunoreactivity was primarily due to the presence of ubiquitin and UCRP conjugated to other proteins, and that although levels of ubiquitin-protein conjugates do not change substantially during pregnancy, decidualization is accompanied by the appearance of conjugates of UCRP. Baboon uterine tissues demonstrated a similar distribution of the two proteins, which indicates that the baboon may be a useful model for study of the role of the ubiquitin system and UCRP in the establishment of pregnancy in humans.  (+info)

Tissue plasminogen activator and its receptor in the human amnion, chorion, and decidua at preterm and term. (8/1114)

The plasminogen activator system consists of two proteins: tissue plasminogen activator (tPA) and urokinase plasminogen activator (uPA), which act upon their specific receptors to generate plasmin from plasminogen located on the cell surface. Plasmin then acts directly and indirectly to degrade the components of the extracellular matrix (ECM). This process is likely to be important in the normal turnover of the ECM of fetal membranes and in its premature weakening in preterm premature rupture of the fetal membranes. Quantitative Northern analysis and in situ hybridization have shown that the decidua expresses mRNA for tPA. However, the immunolocalized tPA protein was most strongly associated with the amnion and chorion, as was its receptor annexin II, suggesting that the amnion and chorion are the targets for decidual tPA. At term, decidual tPA expression was unaffected by labor, and the tPA receptor was elevated both before and after labor. At preterm, the converse was found: decidual tPA expression was significantly (p < 0. 05) up-regulated by labor, but the tPA receptor was not. The results suggest that the generation of plasmin at term would be controlled by an increased concentration of the tPA receptor in the amnion and chorion, whereas at preterm a pathological increase in plasmin would be generated by an overexpression of tPA, initiated by labor.  (+info)

Previous studies from our laboratories established that connexin (Cx)-43 critically regulates endometrial stromal cell (ESC) differentiation, whereas gap junction blockade prevents it. The current study evaluated the plasticity of ESC morphology and Cx43 expression, as well as other biochemical markers of cell differentiation, in response to decidualizing hormones. Primary human ESC cultureswere exposedto 10 nM estradiol, 100 nM progesterone, and 0.5 mM cAMPfor up to 14 days, followed by hormone withdrawal for 14 days, mimicking a biphasic ovulatory cycle.

Methods have been developed for isolating human tissue macrophages from first trimester or term pregnancy decidua. After a two stage enzymic digestion, viable cells were separated from cellular debris by velocity sedimentation at unit gravity or by Percoll centrifugation. Cell populations were analysed by flow cytometry after labelling with monoclonal antibodies. In term decidua, 47% of the cells were of bone marrow origin, comprising 18% macrophages, 3% large granular lymphocytes and 8% T cells. The remaining cells, the proportion of which varied between individuals, were CD16-positive granulocytes. Macrophages were isolated flow cytometrically from both first trimester and term decidual cell dispersions after labelling with an antibody to MHC class II. Yields of up to 4 X 10(6) macrophages, greater than 95% pure, were routinely obtained.
Uterine spiral artery remodeling is required for successful human pregnancy; impaired remodeling is associated with pregnancy complications, including late miscarriage, preeclampsia, and fetal growth restriction. The molecular triggers of remodeling are not known, but it is now clear that there are trophoblast-independent and trophoblast-dependent stages. Uterine natural killer (uNK) cells are abundant in decidualized endometrium in early pregnancy; they surround spiral arteries and secrete a range of angiogenic growth factors. We hypothesized that uNK cells mediate the initial stages of spiral artery remodeling. uNK cells and extravillous trophoblast (EVT) cells were isolated from early pregnancy decidua and placenta. Chorionic plate arteries from full-term placentas and spiral arteries from nonpregnant myometrium were cultured with angiogenic growth factors or conditioned medium (CM) from uNK cells or EVT or uNK cell/EVT cocultures. In both vessel models, uNK cell CM induced disruption of ...

A successful pregnancy requires that the maternal immune system adapts to tolerate the semi-allogeneic fetal-placental unit. This adaptation mainly occurs locally, i.e. at the fetal-maternal interface, where fetal-derived tissues come into close contact with maternal cells in the uterine endometrium (called decidua during pregnancy). Macrophages and regulatory T (Treg) cells are maternal immune cells that are enriched in the decidua and they likely play a central role in promoting fetal tolerance. However, the precise function of decidual macrophages and the factors regulating both macrophages and Treg cells in humans are unknown. The aim of this thesis was to characterize the phenotype and function of decidual macrophages from first trimester human pregnancy and to identify factors responsible for inducing tolerogenic properties in both decidual macrophages and Treg cells. CD14+ decidual macrophages showed characteristics of immune suppressive or homeostatic macrophages (expression of CD163, ...

In this study, we further verify that the levels of CD25 on CD4 + and CD8 + T lymphocytes are not increased in normal pregnancy, although the levels of CD69 and HLA-DR are markedly increased. We also elucidate that the amounts of all three activation molecules on local T lymphocytes are down-regulated in pregnancy ...
Objective: One of the most serious complications after hematopoietic stem cell transplantation is acute graftversus- host disease (GVHD), which develops when donor- derived T-cells recognize and become activated by alloreactive recipient tissue. We were the first to use bone marrow-derived mesenchymal stem cells (BM-MSCs) to reverse severe steroid-refractory acute GVHD and hemorrhagic cystitis. The fetus is protected against the mothers immune system by the fetal membrane. We wanted to explore if stromal cells from the placenta could be used for GVHD and tissue damage in a similar way as MSCs. Materials and Methods: We collected stromal cells from various parts of the placenta. To characterize these cells, we used fluorescence activated cell sorter (FACS). For functional analysis, mixed lymphocyte culture (MLC) and mitogen stimulation of human and mice cells were used. For studies of GVHD, we used B6 mice as donors and Balb/C mice as recipients of hematopoietic stem cell transplants. Patients ...
BackgroundAlthough uterine macrophages are thought to play an important regulatory role at the maternal-fetal interface, their global gene expression profile is not known.Methodology/Principal FindingsUsing micro-array comprising approximately 14,000 genes, the gene expression pattern of human first trimester decidual CD14+ monocytes/macrophages was characterized and compared with the expression profile of the corresponding cells in blood. Some of the key findings were confirmed by real time PCR or by secreted protein. A unique gene expression pattern intrinsic of first trimester decidual CD14+ cells was demonstrated. A large number of regulated genes were functionally related to immunomodulation and tissue remodelling, corroborating polarization patterns of differentiated macrophages mainly of the alternatively activated M2 phenotype. These include known M2 markers such as CCL-18, CD209, insulin-like growth factor (IGF)-1, mannose receptor c type (MRC)-1 and fibronectin-1. Further, the selective up

In cycling rodents, the circulating E and P are produced and secreted by the concerted actions of ovarian granulosa and theca cells (10). The adrenal glands in rodents are incapable of synthesizing significant levels of these steroid hormones (11). In pregnant mice, the corpora lutea develop fully by d 3 of pregnancy and start to produce P, the level of which increases and remains elevated until mid-gestation (12). In contrast, the level of serum E, which is high on d 1 of pregnancy because of the preovulatory hormonal surge, decreases and reaches approximately 15 pg/mL on d 2 and 3. The serum E level increases transiently to approximately 22 pg/mL on d 4 of pregnancy and plays a critical role in embryo attachment. When the embryo attaches to the uterus, the ovarian E synthesis decreases. During the decidualization phase, which lasts from d 5 through 8 of gestation, the circulating level of E remains low at approximately 15 pg/mL (12). When the ovaries were removed after embryo attachment, ...
Introduction: At the maternal fetal interface, the decidua may play a role in labor, a process which involves the prostaglandin (PG) pathway (important clinical target for labor management). However, the PG pathway is highly complex with three rate limiting steps, and its complexity remains to be addressed in the decidua. We hypothesize the decidua exhibits 1) a distinct expression profile of PG genes with labor, and 2) differential expression in preterm labor (PTL) compared to term labor ...
Uterine decidualization, a process that occurs in response to embryo implantation, is critical for embryonic survival and thus is a key event for successful pregnancy. Here we show that the sphingolipid metabolic pathway is highly activated in the deciduum during pregnancy and disturbance of the pathway by disruption of sphingosine kinase (Sphk) genes causes defective decidualization with severely compromised uterine blood vessels, leading to early pregnancy loss. Sphk-deficient female mice (Sphk1-/-Sphk2+/-) exhibited both an enormous accumulation of dihydrosphingosine and sphingosine and a reduction in phosphatidylethanolamine levels in pregnant uteri. These mice also revealed increased cell death in decidual cells, decreased cell proliferation in undifferentiated stromal cells, and massive breakage of decidual blood vessels, leading to uterine hemorrhage and early embryonic lethality. Thus, sphingolipid metabolism regulates proper uterine decidualization and blood vessel stability. Our ...

Abstract: In early human pregnancy, uterine decidual NK cells (dNK) are abundant and considered as cytokine producers but poorly cytotoxic despite their cytolytic granule content, suggesting a negative control of this latter effector function. To investigate the basis of this control, we examined the relative contribution to the cytotoxic function of different activating receptors expressed by dNK. Using a multicolor flow cytometry analysis, we found that freshly isolated dNK exhibit a unique repertoire of activating and inhibitory receptors, identical among all the donors tested. We then demonstrated that in fresh dNK, mAb-specific engagement of NKp46-, and to a lesser extent NKG2C-, but not NKp30-activating receptors induced intracellular calcium mobilization, perforin polarization, granule exocytosis and efficient target cell lysis. NKp46-mediated cytotoxicity is coactivated by CD2 but dramatically blocked by NKG2A coengagement, indicating that the dNK cytotoxic potential could be tightly ...

Uncovering the causes of pregnancy complications such as preterm labor requires greater insight into how the uterus remains in a noncontractile state until term and then surmounts this state to enter labor. Here, we show that dynamic generation and erasure of the repressive histone modification tri-methyl histone H3 lysine 27 (H3K27me3) in decidual stromal cells dictate both elements of pregnancy success in mice. In early gestation, H3K27me3-induced transcriptional silencing of select gene targets ensured uterine quiescence by preventing the decidua from expressing parturition-inducing hormone receptors, manifesting type 1 immunity, and most unexpectedly, generating myofibroblasts and associated wound-healing responses. In late gestation, genome-wide H3K27 demethylation allowed for target gene upregulation, decidual activation, and labor entry. Pharmacological inhibition of H3K27 demethylation in late gestation not only prevented term parturition, but also inhibited delivery while maintaining ...
Even after intensive study, many of the maternal immunological adaptations to pregnancy are not well elucidated. It is known that pregnancy is associated with an increase in the CD4+ T cells that secrete Th2-type cytokines-for example interleukins (Fragiadakis, 2016). Th1-type cytokine production-for example, interferon gamma and interleukin 2-appears to be somewhat suppressed, leading to a Th2 bias in pregnancy. This bias affects the ability to rapidly eliminate certain intracellular pathogens during pregnancy, although the clinical implications of this suppression are unknown (Kourtis, 2014; Svensson-Arvelund, 2014). Importantly, the Th2 humoral immune response remains intact. It also appears that human leukocyte antigen (HLA)-C expressed by extravillous trophoblasts elicits responses from decidual natural killer (dNK) and decidual CD8+ T cells (Crespo, 2017). ...
Immunological adaptations in pregnancy allow maternal tolerance of the semi-allogeneic fetus but also increase maternal susceptibility to infection. At implantation, the endometrial stroma, glands, arteries and immune cells undergo anatomical and functional transformation to create the decidua, the specialized secretory endometrium of pregnancy. The maternal decidua and the invading fetal trophoblast constitute a dynamic junction that facilitates a complex immunological dialogue between the two. The decidual and peripheral immune systems together assume a pivotal role in regulating the critical balance between tolerance and defense against infection. Throughout pregnancy, this equilibrium is repeatedly subjected to microbial challenge. Acute viral infection in pregnancy is associated with a wide spectrum of adverse consequences for both mother and fetus. Vertical transmission from mother to fetus can cause developmental anomalies, growth restriction, preterm birth and stillbirth, while the ...

Mast cells (MCs) are largely known as primary responders in allergic reactions and important cells of the innate immune system. However, recent studies reveal that MCs in fact also play a critical role in the Treg-dependent allograft tolerance by secreting interleukin-9 (IL)-9. In the light of this breaking role for MCs we embarked on a series of studies aiming to analyze whether MCs may be implicated in tolerance towards the semiallogenic fetus growing within the maternal uterus. We confirmed the presence of MCs at the fetal-maternal interface preferentially in maternal decidua (Fig. 1). Their peak is observed around implantation. Fetal rescue by means of antigen-specific Treg was associated with an augmented number of MCs as well as with enhanced expression of MC-related molecules (Tph-1, Mcpt-1 and Mcpt-5) at the fetal-maternal interface and in other organs. Treg treatment was further associated with an increase in the levels of well-known MC growth factors mSCF and IL-3, while IL-9 remained ...
Most of the evidence supporting the sterile womb paradigm was generated with traditional microscopy or culture-based techniques, which are today considered deficient for assessing a microbiome. Researchers have therefore turned to molecular approaches, such as next-generation sequencing, and recent studies have produced evidence (summarized in Table 1) that challenges the sterile womb paradigm. Reports employing these techniques propose that bacteria are not only present within the fetal environment in healthy full-term pregnancies [8, 9, 37, 38], but that they also constitute a placental microbiome that jump-starts the colonization of the fetus [8-10] as part of its normal developmental process [39]. Additionally, it has been suggested that the uterus contains its own microbiome that can contribute to fetal colonization, as the placenta develops from both fetal trophoblasts and maternal decidua (the inner lining of the uterus) [40, 41].. After the early studies on the meconium discussed above, ...

Prvobitna analiza DNK kromosoma Y, koja se, kao i mitohondrijska DNK, nasljeđuje od samo jednog roditelja, bila je dosljedna modelu nedavnog afričkog pretka. Međutim, mitohondrijski i podaci sa Y kromosoma nisu se mogli objasniti istom ekspanzijom modernog čovjeka iz Afrike; ekspanzija Y kromosoma uključivala bi genetsko miješanje koje bi zadržalo regionalno lokalne mitohondrijske linije. Uz to, podaci s Y kromosoma ukazali su na kasnije širenje natrag u Afriku iz Azije, pokazavši da genski tok među regijama nije bio jednosmjeran.[81] Rana analiza 15 nekodirajućih dijelova kromosoma X otkrila je dodatne nepodudarnosti s hipotezom nedavnog afričkog pretka.

Granularity is a characteristic of both dNK and CD56dim pNK cells, both of which are also called large granular lymphocytes (65), whereas CD56bright pNK cells are known to be less granular (15). Granzyme B and perforin (components of cytotoxic granules) were expressed at similar levels in dNK and CD56dim pNK cells, whereas granzyme A was 3- and 10-fold overexpressed in dNK cells versus the CD56dim and CD56bright pNK cells, respectively (Fig. 3 C). Thus, the potential cytolytic function of dNK cells, probably regulated, cannot be ignored. This nascent activity could be manifest in the decidua under special circumstances (e.g., virus infection of the trophoblast or decidual remodeling).. Many other genes overexpressed in dNK cells that are presented in Fig. 3 (e.g., CD31, CD38, MIP-1 α/β, Syk, LEF1, AARS, arp2/3 subunit, and tubulins) may be of considerable interest but are beyond the scope of the present paper.

The part of the chorion that is in contact with the decidua capsularis undergoes atrophy, so that by the fourth month scarcely a trace of the villi is left. This part of the chorion becomes smooth, and is named the chorion laeve (from the Latin word levis, meaning smooth). As it takes no share in the formation of the placenta, this is also named the non-placental part of the chorion. As the chorion grows, the chorion laeve comes in contact with the decidua parietalis and these layers fuse. The villi at the embryonic pole, which is in contact with the decidua basalis, increase greatly in size and complexity, and hence this part is named the chorion frondosum. Thus the placenta develops from the chorion frondosum and the decidua basalis. ...

Tryptophan 2,3-dioxygenase (T do 2) is a rate-limiting enzyme which directs the conversion of tryptophan to kynurenine. The aim of this study was to examine the expression and regulation of T do 2 in mouse uterus during decidualization. T do 2 mRNA was mainly expressed in the decidua on days 6-8 of pregnancy. By real-time PCR, a high level of T do 2 expression was observed in the uteri from days 6 to 8 of pregnancy, although T do 2 expression was observed on days 1-8. Simultaneously, T do 2 mRNA was also detected under in vivo and in vitro artificial decidualization. Estrogen, progesterone, and 8-bromoadenosine-cAMP could induce the expression of T do 2 in the ovariectomized mouse uterus and uterine stromal cells. T do 2 could regulate cell proliferation and stimulate the expression of decidual marker Dtprp in the uterine stromal cells and decidual cells. Overexpression of T do 2 could upregulate the expression of Ahr, Cox2, and Vegf genes in uterine stromal cells, while T do 2 inhibitor 680C91 ...
Decidualization is a process that results in significant changes to cells of the endometrium in preparation for, and during, pregnancy. This includes morphological and functional changes to endometrial stromal cells (ESCs), the presence of decidual white blood cells (leukocytes), and vascular changes to maternal arteries. The sum of these changes results in the endometrium changing into a structure called the decidua. In humans, the decidua is shed during the third phase of birth. Decidualization plays an important role in promoting placenta formation between a mother and her fetus by mediating the invasiveness of trophoblast cells. It also triggers the production of cellular and molecular factors that result in structural changes, or remodeling, of maternal spiral arteries. Decidualization is required in some mammalian species where embryo implantation and trophoblast cell invasion of the endometrium occurs, also known as hemochorial placentation. This allows maternal blood to come into direct ...

The oedematous condition of the decidual stroma is noted in most early ova, but it is usually associated with a certain amount of congestion of the blood vessels throughout the whole decidua. Jung refers particularly to a condition of venous hyperaemia. In my specimen there is no marked congestion in the decidua vera, but merely some enlarged veins here and there. There is in the decidua basalis, especially around the border zone, a noticeable escape of red blood corpuscles into the stroma. This condition is more widespread in my specimen than in ]ungs, where it was confined to the immediate neighbourhood of the border zone. I have not detected anything that could be interpreted as the formation of new capillaries in this zone. This phenomenon is described by Peters, particularly in the capsularis. White blood cells, or at least what appear to be lymphocytes, are to be found in the stroma particularly around the vessels, not only in the decidua basalis but in the vera and capsularis. The ...

Here we show that dynamic and variable decidual angiogenesis (sprouting, intussusception and networking), and active vigorous vascular remodelling such as enlargement and elongation of vascular sinus folding (VSF) and mural cell drop-out occur distinctly in a spatiotemporal manner in the rapidly growing mouse uterus during early pregnancy - just after implantation but before placentation. Decidual angiogenesis is mainly regulated through VEGF-A secreted from the progesterone receptor (PR)-expressing decidual stromal cells which are largely distributed in the anti-mesometrial region (AMR). In comparison, P4 -PR-regulated VEGF-A
Professor Graham Burton. The role of the endometrial glands during human early pregnancy has largely been ignored once implantation is complete. However, we have recently demonstrated that the glands are an important source of nutrients for the conceptus during the first trimester. The glandular secretions also contain a rich mix of growth factors and cytokines, and so play a role in regulating early placental development, modulating trophoblast proliferation and differentiation. In other species, such as the sheep and rabbit, there is good evidence that the secretions are essential for promoting growth of the conceptus. It is also known that in these species signals from the conceptus increase the production of glandular secretions to meet its demands. Our interests now are to identify how endometrial gland secretions are regulated in human early pregnancy, their composition, and their effects on trophoblast behaviour. The project may tackle one or more of these topics depending on the ...
Preeclampsia is a severe complication that occurs in the third trimester of pregnancy, affecting around 8% of pregnant women. If it is not diagnosed on time, it may lead to significant complications with both the mother and fetus. Until now, most research on the topic had focused on investigating defects in placenta formation that resulted in the onset of the disease, ignoring the role of the maternal uterine tissue where the embryo is implanted.. Our study, first author of which is Dr. Tamara Garrido-Gómez, shows the link between the onset of preeclampsia and a defect in the decidualization process in the endometrium. Decidualization is an endometrial process that entails preparing the uterus for the implantation of the embryo and a successful pregnancy. This defect not only occurs in the endometrium of women who have suffered from preeclampsia during a previous pregnancy, but also in patients who have preeclampsia at the time of birth.. This discovery offers an explanation as to why women ...
