Abstract
Decidualization is an intricate biological process in which extensive remodeling of the endometrium occurs to support the development of an implanting blastocyst. However, the immunometabolic mechanisms underlying this process are still largely unknown. We found that the decidualization process is accompanied by the accumulation of fructose-1,6-bisphosphate (FBP). The combination of FBP with pyruvate kinase M stimulated IL-27 secretion by endometrial stromal cells in an ERK/c-FOS-dependent manner. IL-27 induced decidual COX-2+ M2-like macrophage differentiation, which promotes decidualization, trophoblast invasion, and maternal-fetal tolerance. Transfer of Ptgs2+/COX-2+ macrophages prevented fetal loss in Il27ra-deleted pregnant mice. FBP levels were low in plasma and decidual tissues of patients with unexplained recurrent spontaneous abortion. In therapeutic studies, FBP supplementation significantly improved embryo loss by up-regulation of IL-27-induced COX-2+ macrophage differentiation in a mouse model of spontaneous abortion. These findings collectively provide a scientific basis for a potential therapeutic strategy to prevent pregnancy loss.

Abstract
STUDY QUESTION Is the protein l-arginine methyltransferase 3 (PRMT3)/asymmetrical dimethylarginine (ADMA)/nitric oxide (NO) pathway involved in the development of recurrent miscarriage (RM), and what is the potential mechanism? SUMMARY ANSWER Elevated levels of PRMT3 and ADMA inhibit NO formation in the decidua, thereby impairing the functions of trophoblast cells at the maternal-foetal interface. WHAT IS KNOWN ALREADY Decreased NO bioavailability is associated with RM. ADMA, an endogenous inhibitor of nitric oxide synthase (NOS), is derived from the methylation of protein arginine residues by PRMTs and serves as a predictor of mortality in critical illness. STUDY DESIGN, SIZE, DURATION A total of 145 women with RM and 149 healthy women undergoing elective termination of an early normal pregnancy were enrolled. Ninety-six female CBA/J, 24 male DBA/2 and 24 male BALB/c mice were included. CBA/J × DBA/2 matings represent the abortion group, while CBA/J × BALB/c matings represent the normal control group. The CBA/J pregnant mice were then categorised into four groups: (i) normal + vehicle group (n = 28), (ii) abortion + vehicle group (n = 28), (iii) normal + SGC707 (a PRMT3 inhibitor) group (n = 20) and (iv) abortion + SGC707 group (n = 20). All injections were made intraperitoneally on Days 0.5, 3.5 and 6.5 of pregnancy. Decidual tissues were collected on Days 8.5, 9.5 and 10.5 of gestation. The embryo resorption rates were calculated on Day 9.5 and Day 10.5 of gestation. PARTICIPANTS/MATERIALS, SETTING, METHODS NO concentration, ADMA content, NOS activity, expression levels of NOS and PRMTs in decidual tissues were determined using conventional assay kits or western blotting. PRMT3 expression was further analysed in decidual stromal cells, macrophages and natural killer cells. A co-culture system between decidual macrophages (DMs) and HTR-8/SVneo trophoblasts was constructed to study the roles of the PRMT3/ADMA/NO signalling pathway. Trophoblast apoptosis was analysed via Annexin V-fluorescein isothiocyanate/propidium iodide staining. CBA/J × DBA/2 mouse models were used to investigate the effects of SGC707 on embryo resorption rates. MAIN RESULTS AND THE ROLE OF CHANCE Our results show that NO concentration and NOS activity were decreased, but ADMA content and PRMT3 expression were increased in the decidua of RM patients. Moreover, compared with the normal control subjects, PRMT3 expression was significantly up-regulated in the macrophages but not in the natural killer cells or stromal cells of the decidua from RM patients. The inhibition of PRMT3 results in a significant decrease in ADMA accumulation and an increase in NO concentration in macrophages. When co-cultured with DMs, which were treated with SGC707 and ADMA, trophoblast apoptosis was suppressed and induced, respectively. In vivo experiments revealed that the administration of SGC707 reduced the embryo resorption rate of CBA/J × DBA/2 mice. LIMITATIONS, REASONS FOR CAUTION All sets of experiments were not performed with the same samples. The main reason is that each tissue needs to be reserved for clinical diagnosis and only a small piece of each tissue can be cut and collected for this study. WIDER IMPLICATIONS OF THE FINDINGS Our results indicate that the PRMT3/ADMA/NO pathway is a potential marker and target for the clinical diagnosis and therapy of RM. STUDY FUNDING/COMPETING INTEREST(S) This study was supported by the National Key Research and Development Program of China (2017YFC1001401), National Natural Science Foundation of China (81730039, 82071653, 81671460, 81971384 and 82171657) and Shanghai Municipal Medical and Health Discipline Construction Projects (2017ZZ02015).

Abstract
The foetus can be regarded as a half‐allograft implanted into the maternal body. In a successful pregnancy, the mother does not reject the foetus because of the immune tolerance mechanism at the maternal‐foetal interface. The innate immune cells are a large part of the decidual leukocytes contributing significantly to a successful pregnancy. Although the contributions have been recognized, their role in human pregnancy has not been completely elucidated. Additionally, the accumulated evidence demonstrates that the immune checkpoint molecules expressed on the immune cells are co‐inhibitory receptors regulating their activation and biological function. Therefore, it is critical to understand the immune microenvironment and explore the function of the innate immune cells during pregnancy. This review summarizes the classic immune checkpoints such as PD‐1, CTLA‐4 and some novel molecules recently identified, including TIM‐3, CD200, TIGIT and the Siglecs family on the decidual and peripheral innate immune cells during pregnancy. Furthermore, it emphasizes the role of the immune checkpoint molecules in pregnancy‐associated complications and reproductive immunotherapy.

Abstract
Dysregulated extravillous trophoblast invasion and proliferation are known to increase the risk of recurrent spontaneous abortion (RSA); however, the underlying mechanism remains unclear. Herein, in our retrospective observational case-control study we show that villous samples from RSA patients, compared to healthy controls, display reduced succinate dehydrogenase complex iron sulfur subunit (SDHB) DNA methylation, elevated SDHB expression, and reduced succinate levels, indicating that low succinate levels correlate with RSA. Moreover, we find high succinate levels in early pregnant women are correlated with successful embryo implantation. SDHB promoter methylation recruited MBD1 and excluded c-Fos, inactivating SDHB expression and causing intracellular succinate accumulation which mimicked hypoxia in extravillous trophoblasts cell lines JEG3 and HTR8 via the PHD2-VHL-HIF-1α pathway; however, low succinate levels reversed this effect and increased the risk of abortion in mouse model. This study reveals that abnormal metabolite levels inhibit extravillous trophoblast function and highlights an approach for RSA intervention.

Abstract
Twenty-one strains of termite-associated actinomycetes were tested for their activities against three bacteria. The results showed that nine strains showed bacteriostatic activities against at least one tested bacterium, and the actinomycete YH01, which was isolated from the body surface of the queen of Odontotermes formosanus, had potent antibacterial activity. The YH01 was further identified as Streptomyces davaonensis. Two metabolites roseoflavin (1) and 8-methylamino-8-demethyl-d-riboflavin (2) were isolated and purified from S. davaonensis YH01. Their structures were determined by NMR, MS, and the related literature. The metabolite 1 showed strong inhibition activities against Bacillus subtilis (MIC = 1.56 μg/mL) and Staphylococcus aureus (MIC = 3.125 μg/mL), which were comparable to referenced gentamycin sulfate, with MIC values of 1.56 and 1.56 μg/mL, respectively. Furthermore, the anti-MRSA potential of compound 1 was determined against nine kinds of MRSA strains, with inhibition zones in the ranges of 12.7-19.7 mm under a concentration of 15 μg/6 mm discs and 18.3-22.7 mm under a concentration of 30 μg/6 mm discs. However, metabolite 1 had no inhibitory effect on Gram-negative bacteria. These results suggested that roseoflavin produced by YH01 holds promise for use against Gram-positive bacteria, especially to MRSA.

Abstract
PROBLEM Decidual natural killer (dNK) cells play key roles in maternal-fetal immune regulation, trophoblast invasion, and vascular remodeling, and most dNK cell populations are CD56bright CD16- NK cells. However, the enrichment and redistribution of dNK cells in the local decidua have not been clarified yet. METHOD OF STUDY A total of 45 women with normal pregnancies and 8 unexplained recurrent spontaneous abortion (RSA) patients were included. We isolated primary human dNK (n = 53) and peripheral blood NK (pNK) cells (n = 5) from specimen and analyzed CD56, CD82, and CD29 by flow cytometry (FCM). We assessed their adhesion ability by cell counts of NK cells adhered to decidual stromal cells (DSCs) in a co-culture system. RESULTS We found that RSA patients had more CD56dim dNK cells with lower CD82 and higher CD29 than women with normal pregnancies. There were negative correlations of CD82 to CD29 on CD56dim and CD56+ dNK cells. In normal pregnancies, dNK cells had lower CD82 and higher CD29 expression with a stronger adhesion ability than pNK cells. Blocking CD82 on dNK cells increased the adhesive ability and CD29 expression, while blocking CD29 decreased the adhesive ability. Co-culturing dNK cells with trophoblast cells decreased CD82 expression and increased the adhesive ability of dNK cells and the percentage of CD56bright NK cells, while blocking trophoblast-derived CXCL12 increased CD82 expression, decreased CD29 expression, and impaired the adhesive ability of NK cells. CONCLUSION Trophoblast cells enhance the adhesive ability of NK cells to DSCs via the CXCL12/CD82/CD29 signaling pathway and contribute to CD56bright NK cell enrichment in the uterus.

Abstract
Recurrent spontaneous abortion (RSA) refers to the unintentional termination of two or more consecutive pregnancies that severely threatens human reproductive health. Our previous study has shown that miR-184 is expressed more highly in RSA than in normal pregnancy, whether in the villus or decidua. In this study, compared with normal pregnant women, the expression of miR-184 in decidual stromal cells (DSCs) and decidual immune cells (DICs), as well as in peripheral blood, from RSA patients was enhanced similarly. Moreover, we found miR-184 could promote the apoptosis and repress the proliferation of trophoblast cells. Further exploration indicated that miR-184 upregulated the expression of Fas by targeting WIG1 thus inducing cell apoptosis. Finally, after miR-184 overexpression in vivo, the embryo resorption rate in pregnant mice was increased significantly. Therefore, our study outlines the pivotal role of miR-184 in maintaining successful pregnancy, providing a new diagnostic and therapeutic target for RSA.

Abstract
Preeclampsia is a pregnancy-specific disorder that is a major cause of maternal and fetal morbidity and mortality with a prevalence of 6–8% of pregnancies. Although impaired trophoblast invasion in early pregnancy is known to be closely associated with preeclampsia, the underlying mechanisms remain elusive. Here we revealed that lysyl oxidase (LOX) and LOX-like protein 2 (LOXL2) play a critical role in preeclampsia. Our results demonstrated that LOX and LOXL2 expression decreased in preeclamptic placentas. Moreover, knockdown of LOX or LOXL2 suppressed trophoblast cell migration and invasion. Mechanistically, collagen production was induced in LOX- or LOXL2-downregulated trophoblast cells through activation of the TGF-β1/Smad3 pathway. Notably, inhibition of the TGF-β1/Smad3 pathway could rescue the defects caused by LOX or LOXL2 knockdown, thereby underlining the significance of the TGF-β1/Smad3 pathway downstream of LOX and LOXL2 in trophoblast cells. Additionally, induced collagen production and activated TGF-β1/Smad3 were observed in clinical samples from preeclamptic placentas. Collectively, our study suggests that the downregulation of LOX and LOXL2 leading to reduced trophoblast cell migration and invasion through activation of the TGF-β1/Smad3/collagen pathway is relevant to preeclampsia. Thus, we proposed that LOX, LOXL2, and the TGF-β1/Smad3/collagen pathway can serve as potential markers and targets for clinical diagnosis and therapy for preeclampsia. Cancer-associated proteins play a role in preeclampsia, a potentially life-threatening disorder of pregnancy marked by high blood pressure and protein in the urine. The causes of preeclampsia are poorly understood, but the tissue that nourishes the fetus, the placenta, is known to be involved. Knowing that for healthy placenta formation, cells called trophoblasts must show cancer cell-like behavior and invade the developing tissue, Li-Ping Jin and Kai Wang at Tongji University School of Medicine in Shanghai, China, and co-workers investigated the role of cancer-associated LOX proteins, previously linked to cell invasiveness. Preeclamptic placentas showed low LOX levels, poor trophoblast invasion, and excessive formation of collagen, an important connective tissue. Further analysis showed that this excessive collagen is broken down, becoming the diagnostic urinary protein. These results illuminate potential markers for early diagnosis and treatment of preeclampsia.

Abstract
Impaired NK cell cytotoxic activity contributes to the local dysfunctional immune environment in endometriosis (EMS), which is an estrogen-dependent gynecological disease that affects the function of ectopic endometrial tissue clearance. The reason for the impaired cytotoxic activity of NK cells in an ectopic lesion microenvironment (ELM) is largely unknown. In this study, we show that the macroautophagy/autophagy level of endometrial stromal cells (ESCs) from EMS decreased under negative regulation of estrogen. The ratio of peritoneal FCGR3- NK to FCGR3+ NK cells increases as EMS progresses. Moreover, the autophagy suppression results in the downregulation of HCK (hematopoietic cellular kinase) by inactivating STAT3 (signal transducer and activator of transcription 3), as well as the increased secretion of the downstream molecules CXCL8/IL8 and IL23A by ESCs, and this increase induced the upregulation of FCGR3- NK cells and decline of cytotoxic activity in ELM. This process is mediated through the depression of microRNA MIR1185-1-3p, which is associated with the activation of the target gene PTGS2 in NK cells. FCGR3- NK with a phenotype of PTGS2/COX2high IFNGlow PRF1low GZMBlow induced by hck knockout (hck-/-) or 3-methyladenine (3-MA, an autophagy inhibitor)-stimulated ESCs accelerates ESC's growth both in vitro and in vivo. These results suggest that the estrogen-autophagy-STAT3-HCK axis participates in the differentiation of PTGS2high IFNGlow PRF1low GZMBlow FCGR3- NK cells in ELM and contributes to the development of EMS. This result provides a scientific basis for potential therapeutic strategies to treat diseases related to impaired NK cell cytotoxic activity.

Abstract
BACKGROUND Decidual γδ T cells are known to regulate the function of trophoblasts at the maternal-fetal interface; however, little is known about the molecular mechanisms of cross talk between trophoblast cells and decidual γδ T cells. METHODS Expression of chemokine C-X-C motif ligand 6 (CXCL16) and its receptor CXCR6 was evaluated in first-trimester human villus and decidual tissues by immunohistochemistry. γδ T cells were isolated from first-trimester human deciduae and cocultured with JEG3 trophoblast cells. Cell proliferation and apoptosis-related molecules, together with cytotoxicity factor and cytokine production, were measured by flow cytometry analysis. RESULTS Expression of CXCL16 and CXCR6 was reduced at the maternal-fetal interface in patients who experienced unexplained recurrent spontaneous abortion as compared to healthy pregnancy women. With the administration of pregnancy-related hormones or coculture with JEG3 cells, CXCR6 expression was upregulated on decidual γδ T cells. CXCL16 derived from JEG3 cells caused a decrease in granzyme B production of decidual γδ T cells. In addition, decidual γδ T cells educated by JEG3-derived CXCL16 upregulated the expression of Bcl-xL in JEG3 cells. CONCLUSION This study suggested that the CXCL16/CXCR6 axis may contribute to maintaining normal pregnancy by reducing the secretion of cytotoxic factor granzyme B of decidual γδ T cells and promoting the expression of antiapoptotic marker Bcl-xL of trophoblasts.

Abstract
Endometriosis (EMS) is an estrogen-dependent gynecological disease with a low autophagy level of ectopic endometrial stromal cells (eESCs). Impaired NK cell cytotoxic activity is involved in the clearance obstruction of the ectopic endometrial tissue in the abdominopelvic cavity. Protopanaxadiol (PPD) and protopanaxatriol (PPT) are two metabolites of ginsenosides, which have profound biological functions, such as anti-cancer activities. However, the role and mechanism of ginsenosides and metabolites in endometriosis are completely unknown. Here, we found that the compounds PPD, PPT, ginsenoside-Rg3 (G-Rg3), ginsenoside-Rh2 (G-Rh2), and esculentoside A (EsA) led to significant decreases in the viability of eESCs, particularly PPD (IC50 = 30.64 µM). In vitro and in vivo experiments showed that PPD promoted the expression of progesterone receptor (PR) and downregulated the expression of estrogen receptor α (ERα) in eESCs. Treatment with PPD obviously induced the autophagy of eESCs and reversed the inhibitory effect of estrogen on eESC autophagy. In addition, eESCs pretreated with PPD enhanced the cytotoxic activity of NK cells in response to eESCs. PPD decreased the numbers and suppressed the growth of ectopic lesions in a mouse EMS model. These results suggest that PPD plays a role in anti-EMS activation, possibly by restricting estrogen-mediated autophagy regulation and enhancing the cytotoxicity of NK cells. This result provides a scientific basis for potential therapeutic strategies to treat EMS by PPD or further structural modification.

Abstract
Embryo implantation is essential for a successful pregnancy, and leads to the decidualization of endometrial stromal cells (ESCs) in the secretory phase of the menstrual cycle. It has previously been demonstrated that decidual stromal cells (DSCs) co‑express interleukin (IL)‑25/IL‑17RB and that IL‑25 further promotes the proliferation of DSCs via activating c‑Jun n‑terminal kinase and protein kinase B signals, therefore the present study primarily focused on the role of IL‑25 in the process of decidualization in vitro. It was demonstrated that the expression of IL‑25/IL‑17RB in ESCs was decreased compared with DSCs. In addition, following decidualization, the expression levels of IL‑25/IL‑17RB in ESCs were significantly elevated. Recombinant human (rh) IL‑25 promoted the decidualization of ESCs in the presence of 8‑bromoadenosine 3',5'‑cyclic monophosphate sodium salt and 6α‑methyl17α‑acetoxyprogesterone, which was partially inhibited by anti‑human IL‑25 neutralizing antibody (anti‑IL‑25) or anti‑IL‑17RB. In addition, decidual natural killer (dNK) cells not only secreted IL‑25, however also further accelerated the decidualization in vitro. Therefore, these findings indicated that ESCs differentiate into DSCs in the presence of ovarian hormones, resulting in the upregulation of IL‑25/IL‑17RB expression in ESCs. Furthermore, IL‑25 secreted by ESCs and dNK cells further facilitates the decidualization of ESCs, which may form a positive feedback mechanism at the maternal‑fetal interface and thus contribute to the establishment and maintenance of normal pregnancy.

Abstract
Decidual immune cells (DICs), consisting of both innate and adaptive immune cells, have a pivotal role in maintaining immune tolerance for normal pregnancy. Our previous study demonstrated that interleukin (IL)-25 stimulates the proliferation of decidual stromal cells (DSCs) in an autocrine manner. However, the role of IL-25 in functional regulation of DICs is largely unknown. Flow cytometry was used to analyze the expression of IL-25 and its receptor (IL-17RB) in DICs, and the effect of IL-25 on the expression of Ki-67, IL-4, IL-10, interferon (IFN)-γ and transforming growth factor (TGF)-β in decidual γδT cells. In addition, ELISA assays were performed to detect the secretion of IL-10 and TGF-β in decidual γδT cells. The present findings indicated that decidual CD56 bright CD16-natural killer (NK) cells, natural killer T (NKT) cells, regulatory T (Treg) cells, CD3+ T cells, macrophages and γδT cells co-expressed IL-25 and IL-17RB, particularly γδT cells. Recombinant human (rh) IL-25 protein upregulated the expression of Ki-67, IL-4, and IL-10, but downregulated the expression of IFN-γ in γδT cells; however, anti-human IL-25 or IL-17RB neutralizing antibody reversed these effects. These data suggest that IL-25 may promote IL-10 production by γδT cells as well as the proliferation of γδT cells, and possibly forms a positive feedback loop to maintain a T helper 2 cell bias at the maternal-fetal interface and further contributes to the maintenance of successful pregnancy.

Abstract
Ovarian cancer, the third most common with highest mortality rates gynecological malignancy among women in China, is characterized by a unique tumor immune microenvironment. Immune-cell population infiltrated into the tumor tissue among patients with ovarian cancer are associated positively or negatively with antitumor activity. The imbalance between immune activation and immune suppression can result in oncogenesis and cancer progression. Therefore, intense investigation of the immunologic mechanism of ovarian cancer is urgently needed, and a comprehensive understanding of the network in which immune cells interact with the microenvironment, tumor cells and each other will greatly promote the development of more effective immunotherapies for ovarian cancer. In this review, we will focus on the main immune-cell population in ovarian tumor microenvironment, discuss their role in tumor progression and try to give the readers a new perspective in finding more promising therapeutic targets for cancers.

Abstract
Interleukin-33 (IL-33) promotes migration of cancer cells through downregulating the expression of E-cadherin. Previous studies have demonstrated that IL-33 stimulates the proliferation of trophoblasts. However, the effect of IL-33 on the adhesion and invasion of trophoblasts has not been investigated in detail. In the present study, the expression of IL-33 and its receptor, IL-1 receptor-like 1 (ST2), was examined in villi from women during early pregnancy using immunohistochemistry. ST2 expression on human trophoblast and choriocarcinoma cell lines JAR, BeWo, JEG3 and HTR8 was confirmed by flow cytometry (FCM) assay. The effect of recombinant human IL-33 (rhIL-33) on adhesion, invasion and associated molecules was analyzed by cell adhesion, Matrigel invasion and FCM assays. The current study identified that human trophoblasts expressed IL-33 and ST2. RhIL-33 inhibited trophoblast invasion and adhesion, and decreased adhesion and invasion-associated molecules such as integrin α4β1 and CD62L. Therefore, these results suggest that IL-33 may serve an important role in limiting invasion and implantation of trophoblasts by adhesion and invasion-associated molecules, contributing to the formation of the placenta and maintenance of normal pregnancy during early pregnancy.

Abstract
Macrophages play an important role in the origin and development of endometriosis. Estrogen promoted the growth of decidual stromal cells (DSCs) by downregulating the level of interleukin (IL)-24. The aim of this study was to clarify the role and mechanism of IL-24 and its receptors in the regulation of biological functions of endometrial stromal cells (ESCs) during endometriosis. The level of IL-24 and its receptors in endometrium was measured by immunohistochemistry.In vitroanalysis was used to measure the level of IL-24 and receptors and the biological behaviors of ESCs. Here, we found that the expression of IL-24 and its receptors (IL-20R1 and IL-20R2) in control endometrium was significantly higher than that in eutopic and ectopic endometrium of women with endometriosis. Recombinant human IL-24 (rhIL-24) significantly inhibited the viability of ESCs in a dosage-dependent manner. Conversely, blocking IL-24 with anti-IL-24 neutralizing antibody promoted ESCs viability. In addition, rhIL-24 could downregulate the invasiveness of ESCsin vitro. After co-culture, macrophages markedly reduced the expression of IL-24 and IL-20R1 in ESCs, but not IL-22R1. Moreover, macrophages significantly restricted the inhibitory effect of IL-24 on the viability, invasion, the proliferation relative gene Ki-67, proliferating cell nuclear antigen (PCNA) and cyclooxygenase2 (COX-2), and the stimulatory effect on the tumor metastasis suppressor gene CD82 in ESCs. These results indicate that the abnormally low level of IL-24 in ESCs possibly induced by macrophages may lead to the enhancement of ESCs’ proliferation and invasiveness and contribute to the development of endometriosis.

Abstract
Temperature is one of the most important environmental parameters with crucial impacts on nearly all biological processes. Due to anthropogenic activity, average air temperatures are expected to increase by a few degrees in coming decades, accompanied by an increased occurrence of extreme temperature events. Such global trends are likely to have various major impacts on human society through their influence on natural ecosystems, food production and biotic interactions, including diseases. In this study, we used a combination of statistical genetics, experimental evolution and common garden experiments to investigate the evolutionary potential for thermal adaptation in the potato late blight pathogen, Phytophthora infestans, and infer its likely response to changing temperatures. We found a trade-off associated with thermal adaptation to heterogeneous environments in P. infestans, with the degree of the trade-off peaking approximately at the pathogen's optimum growth temperature. A genetic trade-off in thermal adaptation was also evidenced by the negative association between a strain's growth rate and its thermal range for growth, and warm climates selecting for a low pathogen growth rate. We also found a mirror effect of phenotypic plasticity and genetic adaptation on growth rate. At below the optimum, phenotypic plasticity enhances pathogen's growth rate but nature selects for slower growing genotypes when temperature increases. At above the optimum, phenotypic plasticity reduces pathogen's growth rate but natural selection favours for faster growing genotypes when temperature increases further. We conclude from these findings that the growth rate of P. infestans will only be marginally affected by global warming.

Abstract
Discovered 30 years ago, γδT cells remain an enigmatic T-cell subset. Although they account for a small portion of the total human circulating T-cell pool, their associations with other immune cells and their potential regulatory roles in related diseases have been explored but still require further investigation. γδT cells which are MHC-unrestricted innate-like lymphocytes with more unique antigen receptors than αβT cells and B cells are considered to bridge innate and adaptive immunity. They have APC functions and initiate adaptive immunity. Due to their distribution in specific tissues, secretion of Th1-, Th2-, and Th17-type cytokines, and other characteristics, they are involved in a variety of physiology and pathology processes. They are barometers in HIV infection. However, different γδT cell subsets play opposing roles in HBV infections, autoimmune diseases, and several types of tumors. Moreover, decidual γδT cells have protective roles during pregnancies by synthesizing several cytokines. This emerging evidence provides an improved understanding of the immune mechanism of infection, autoimmunity, cancer, and other related disorders and better insights regarding the potential roles of γδT cells in immunological therapeutic strategies.

Abstract
Cervical cancer is often associated with hypoxia and many kinds of chemokines. But the relationship and role of hypoxia and Chemokine (C-C motif) ligand 17 (CCL17) in cervical cancer are still unknown. Here, we found that CCL17 was high expressed in cervical cancer. HeLa and SiHa cells could secrete CCL17 in a time-dependent manner. Hypoxia increased expression of CCL17 receptor (CCR4) on HeLa and SiHa cells. Treatment with recombination human CCL17 (rhCCL17) led to an elevation of cell proliferation in HeLa and SiHa cells in a dose-dependent manner. In contrast, blocking CCL17 with anti-human CCL17 neutralizing antibody (α-CCL17) played an oppose effect. However, rhCCL17 had no effect on apoptosis in cervical cancer cells. Further analysis showed that hypoxia promoted the proliferation of HeLa and SiHa cells, and these effects could be reversed by α-CCL17. Stimulation with the inhibitor for c-Jun N-terminal kinase (JNK) or signal transducers and activator of transcription 5 (STAT5) signal pathway not only directly decreased the proliferation of HeLa and SiHa cells, but also abrogated the stimulatory effect of rhCCL17 on the proliferation of HeLa and SiHa cells. These results suggest that a high level of CCL17 in cervical cancer lesions is an important regulator in the proliferation of cervical cancer cells through JNK and STAT5 signaling pathways. In this process, hypoxia magnifies this effect by up-regulating CCR4 expression and strengthening the interaction of CCL17/CCR4.

Abstract
Chemokine CCL24, acting through receptor CCR3, is a potent chemoattractant for eosinophil in allergic diseases and parasitic infections. We recently reported that CCL24 and CCR3 are co-expressed by trophoblasts in human early pregnant uterus. Here we prove with evidence that steroid hormones estradiol (E), progesterone (P), and human chorionic gonadotropin (hCG), as well as decidual stromal cells (DSCs) could regulate the expression of CCL24 and CCR3 of trophoblasts. We further investigate how trophoblast-derived CCL24 mediates the function of trophoblasts in vitro, and conclude that CCL24/CCR3 promotes the proliferation, viability and invasiveness of trophoblasts. In addition, analysis of the downstream signaling pathways of CCL24/CCR3 show that extracellular signal-regulated kinases (ERK1/2) and phosphoinositide 3-kinase (PI3K) pathways may contribute to the proliferation, viability and invasiveness of trophoblasts by activating intracellular molecules Ki67 and matrix metallopeptidase 9 (MMP9). However, we did not observe any inhibitory effect on trophoblasts when blocking c-Jun N-terminal kinase (JNK) or p38 pathways. In conclusion, our data suggests that trophoblast-derived CCL24 at the maternal-fetal interface promotes trophoblasts cell growth and invasiveness by ERK1/2 and PI3K pathways. Meanwhile, pregnancy-related hormones (P and hCG), as well as DSCs could up-regulate CCL24/CCR3 expression in trophoblasts, which may indirectly influence the biological functions of trophoblasts. Thus, our results provide a possible explanation for the growth and invasion of trophoblasts in human embryo implantation.

Abstract
The aim of this retrospective study was to compare the immune tolerance status of patients suffered from unexplained spontaneous abortion (URSA) before and after treatment with paternal lymphocyte induced immunization (PLII) four times, and its relationship to the pregnancy outcome. 168 URSA patients were included in the present study. Among 168 couples, 138 couples were conceived again, of whom 86 were successfully pregnant till 20 gestational weeks, 31 cases again failed in the first trimester, 21 cases were still under follow-up, another 30 cases still had not conceived. Both the level of one way mixed lymphocyte culture blocking efficiency (MLC-BE) and anti-idio blocking antibody (BE-Ab2) were markedly elevated in succeeded group after PLII. In contrast, although a significant increase could be observed in the failed group after treatment, the elevation of BE-Ab2 was much lower than that in successful group. PLII therapy significantly up-regulated the percentage of peripheral CD4(+)CD25(+)CD127(-) regulatory T cells (Tregs) in successfully pregnant women; however, there was no significant change of Tregs in pregnancy loss cases although receiving PLII therapy. These results suggested a positive correlation between higher frequency of Tregs and rate of successful pregnancies. The sensitivity and specificity of combination of Tregs with MLC-BE and BE-Ab2 were 81.8% and 81.3%, respectively. Therefore, the percentage of Tregs in peripheral blood may hopefully serve as a potential biomarker for monitoring the efficacy of therapy in URSA patients. Combination of Tregs with MLC-BE and BE-Ab2 may expect to better evaluate the efficacy of PLII in URSA patients.

Abstract
It has reported that interleukin-22 (IL-22) promotes the invasion of tumor cells. IL-22 in the endometriotic milieu stimulates the proliferation of human endometrial stromal cells (ESCs). The present study aimed to elucidate whether and how IL-22 regulates the invasion of ESCs from adenomyosis. The expression of IL-22 and its receptors in normal endometrium, eutopic endometrium and ectopic lesion was analyzed by immunohistochemistry; the invasiveness of ESCs in vitro was verified by Matrigel invasion assay; and the effects of IL-22 on the correspondent functional molecules were investigated by ELISA and flow cytometry. Here we found that IL-22 and its receptors IL-22R1 and IL-10R2 in eutopic endometrium and ectopic lesion of adenomyosis were significantly higher than that of normal endometrium. Recombinant human IL-22 (rhIL-22) increased IL-22R1 and IL-10R2 levels on ESCs. Moreover, rhIL-22 promoted the invasiveness of ESCs, and inhibited the expression of metastasis suppressor gene CD82, stimulated the secretion of IL-8, RANTES, IL-6 and VEGF of ESCs. On the contrary, the neutralizing antibody for IL-22 reversed these effects. Our current study has demonstrated that IL-22 has a positive feedback on the expression of its receptors IL-22R1 and IL-10R2 on ESCs. This autocrine effect of IL-22 promotes the invasion of ESCs possibly through regulating invasion-related molecules, suggesting that the abnormal high expression of IL-22 may play an important role in ESCs invasion and finally contribute to the origin and development of adenomyosis.

Abstract
Mammalian proprotein convertases (PCs) play an important role in folliculogenesis, as they proteolytically activate a variety of substrates such as the transforming growth factor beta (TGFβ) superfamily. PC subtilism/kexin 6 (PCSK6) is a member of the PC family and is ubiquitously expressed and implicated in many physiological and pathological processes. However, in human granulosa cells, the expression of the PC family members, their hormonal regulation, and the function of PCs are not clear. In this study, we found that PCSK6 is the most highly expressed PC family member in granulosa cells. LH increased PCSK6 mRNA level and PCSK6 played an anti-apoptosis function in KGN cells. Knockdown of PCSK6 not only increased the secretion of activin A and TGFβ2 but also decreased the secretion of follistatin, estrogen, and the mRNA levels of FSH receptor (FSHR) and P450AROM (CYP19A1). We also found that, in the KGN human granulosa cell line, TGFβ2 and activin A could promote the apoptosis of KGN cells and LH could regulate the follistatin level. These data indicate that PCSK6, which is regulated by LH, is highly expressed in human primary granulosa cells of pre-ovulatory follicles and plays important roles in regulating a series of downstream molecules and apoptosis of KGN cells.

Abstract
In the peritoneal fluid, macrophages and their secretory cytokines are essential for endometriosis, but the factors that favor their involvement in the endometriosis-associated inflammatory response are still elusive. Given the anomalous expression of indoleamine 2,3-dioxygenase-1 (IDO1) in endometrial stromal cells (ESCs) and its potentially important roles in immune modulation, we aimed to determine the effects of IDO1 in ESCs on macrophages and the mechanism of those effects. Normal ESCs and ectopic ESCs transfected with the SD11-IDO1 shRNA (short hairpin RNA) or vector-only plasmid SD11 were subsequently co-cultured with peripheral blood (PB)-derived monocytes (PBMC)-driven macrophages directly and indirectly. Cytokine production was determined by analyzing the supernatant of the co-culture unit by enzyme-linked immunosorbent assay (ELISA). The phenotypes and the phagocytic ability of the macrophages were determined by flow cytometry. Compared to normal ESCs, the PBMC-driven macrophages co-cultured with ectopic ESCs displayed lower phagocytic ability. Additionally, macrophages co-cultured with ectopic ESCs exhibited higher levels of CD163 and CD209 and lower levels of HLA-DR and CD11c. Moreover, both the intracellular expression and extracellular secretion of interleukin-10 (IL-10) and transforming growth factor-β1 (TGF-β1) were significantly increased, while that of IL-12p70 was decreased in macrophages after being co-cultured with ectopic ESCs. However, there was no significant difference in macrophage phagocytic ability, immunophenotype or cytokine secretion between the direct and indirect co-culture units. Reversely, SD11-IDO1 shRNA transfection of ectopic ESCs could abrogate the decreased phagocytic ability and alternative activation of macrophages in ectopic ESC-macrophage co-culture unit, suggesting that higher IDO1 in ectopic ESCs was indispensable for the induction of macrophage tolerance. Furthermore, the decrease in phagocytic macrophages and alternatively activated macrophages induced by IDO1 in ectopic ESCs was reversed by the addition of an IL-33 inhibitor, that is, soluble ST2 (sST2). Therefore, through the activation of IL-33, the increased expression of IDO1 in ectopic ESCs contributed to the truncated phagocytic ability of macrophages in endometriosis.

Abstract
Physiological pregnancy requires the maternal immune system to recognize and tolerate embryonic Ags. Although multiple mechanisms have been proposed, it is not yet clear how the fetus evades the maternal immune system. In this article, we demonstrate that trophoblast-derived thymic stromal lymphopoietin (TSLP) instructs decidual CD11c(+) dendritic cells (dDCs)with increased costimulatory molecules; MHC class II; and Th2/3-type, but not Th1-type, cytokines. TSLP-activated dDCs induce proliferation and differentiation of decidual CD4(+)CD25(-) T cells into CD4(+)CD25(+)FOXP3(+) regulatory T cells (Tregs) through TGF-β1. TSLP-activated dDC-induced Tregs display immunosuppressive features and express Th2-type cytokines. In addition, decidual CD4(+)CD25(+)FOXP3(+) Tregs promote invasiveness and HLA-G expression of trophoblasts, resulting in preferential production of Th2 cytokines and reduced cytotoxicity in decidual CD56(bright)CD16(-) NK cells. Of interest, decreased TSLP expression and reduced numbers of Tregs were observed at the maternal-fetal interface during miscarriage. Our study identifies a novel feedback loop between embryo-derived trophoblasts and maternal decidual leukocytes, which induces a tolerogenic immune response to ensure a successful pregnancy.

Abstract
Interleukin (IL)-33, a newly described member of the IL-1 family, has been reported to facilitate primary tumor progression and metastatic dissemination. However, its biological function on decidual stromal cells (DSCs) remains unclear. In this study, we tested the hypothesis whether IL-33 promotes proliferation and invasion of DSCs, and the possible mechanism. IL-33 and its orphan receptor ST2 was found to be co-expressed by DSCs in human first-trimester pregnancy. Addition of IL-33, enhanced the proliferation and invasion of DSCs in a dosage-dependent manner, concomitantly with increasing expression of proliferation relative gene (PCNA, survivin) and invasion relative gene (titin, MMP2). Blocking IL-33/ST2 signaling by soluble sST2 apparently abolished the stimulatory effect on the proliferation, invasiveness and related gene expression in DSCs. We also demonstrated that chemokines CCL2/CCR2 was significantly increased with IL-33 administration. Moreover, inhibition of CCL2/CCR2 activation using CCL2 neutralizing antibody or CCR2 blocker prevented IL-33-stimulated proliferation and invasiveness capacity of DSCs. Increasing phosphorylation of nuclear factor NF-κB p65 and extracellular signal-regulated kinases ERK1/2 after treatment with IL-33 was confirmed by western blotting. And the IL-33-induced CCL2/CCR2 expression was abrogated by treatment with the NF-κB inhibitor BAY 11-7082 or ERK1/2 inhibitor U0126. Finally, we showed that decreased IL-33/ST2 expression was observed in DSCs from spontaneous abortion compared with normal pregnancy at both gene and protein levels. This study provides evidence for the molecular mechanism of IL-33 in promoting proliferation and invasiveness of DSCs by up-regulation of CCL2/CCR2 via NF-κB and ERK1/2 signal pathways and thus contributes insight to the potential of IL-33 involved in successful pregnancy via inducing DSCs mitosis and invasion.

Abstract
Nonmetastatic gene 23-H1 (NME1, also known as nm23-H1) is a wide-spectrum tumor metastasis suppressor gene that plays an important role in suppressing the proliferation, adhesion and invasion of endometrial stromal cells (ESCs). The present study is undertaken to explore the mechanism by which NME1 in ESCs from endometriosis modulates the angiogenesis and herein participates in the pathogenesis of endometriosis. The expression of NME1 in the primary ESCs from normal endometrium without endometriosis was higher than that from eutopic endometrium and ectopic lesion with endometriosis. Silencing NME1 stimulated the secretion of angiogenic factors interleukin-8 (IL-8) and vascular-endothelial growth factor (VEGF) of the eutopic ESCs from women with endometriosis, and these effects could be abrogated by MAPK/ERK1/2 or AKT inhibitor. In addition, the supernatant of NME1-silenced ESCs increased the expression of angiogenesis-relative molecules CD62E and CD105, and promoted angiogenesis of human umbilical vein endothelial cells (HUVECs). Anti-human IL-8 or VEGF neutralizing antibody reversed the effect on angiogenesis of HUVECs induced by NME1-silenced ESCs. Our current results suggest that the abnormal lower expression of NME1 in ESCs secrete more IL-8 and VEGF through activation of MAPK/ERK1/2 and AKT signal pathways, up-regulate the level of CD62E and CD105, and finally lead to numerous angiogenesis of vascular endothelial cells in the endometriotic milieu, which is beneficial to the origin and development of endometriosis.

Abstract
Failure of the embryo to implant now constitutes the major limiting step in IVF treatment. Successful implantation requires a vital embryo and an effective molecular dialogue with a 'receptive' endometrium. However, what precisely constitutes a receptive human endometrium remains poorly defined. Several observations have indicated that ovarian stimulation for IVF may impair endometrial receptivity. The histological approach to monitor endometrial maturation requires an invasive biopsy that excludes its use during the luteal phase of cycles in which implantation is the end-point objective as in IVF. In recent years, several studies have been reported that the removal of endometrial secretions immediately prior to embryo transfer provides sufficient material for analysis of markers of receptivity without disrupting embryo implantation. Therefore, analysis of protein patterns in endometrial secretion fluid may offer a relatively non-invasive means of assessing endometrial receptivity during fertility treatment cycles. Several studies have shown that protein profile expression in endometrial secretions undergo cyclical changes, and demonstrated significant differences between the natural cycle and stimulated cycle. These findings suggest that endometrial secretion analysis provide a novel means of investigating the effect of ovarian stimulation on the intrauterine environment at the time of embryo transfer, which may help to develop less disruptive ovarian stimulation protocols for IVF in the future.

Abstract
Our previous studies have demonstrated that cyclosporin A (CsA) promotes the proliferation and migration of human trophoblasts via the mitgen-activated protein kinase-3/1 (MAPK3/1) pathway. In the present study, we further investigated the role of nuclear factor (NF)-κB in the CsA-induced trophoblast proliferating cell nuclear antigen (PCNA) expression and migration, and its relationship to MAPK3/1 signal. Flow cytometry was used to analyze the expression of PCNA in trophoblasts. The migration of human primary trophoblasts was determined by wound-healing assay and transwell migration assay. Western blot analysis was performed to evaluate the activation of NF-κB p65 and NF-κB inhibitory protein I-κB in human trophoblasts. We found that treatment with CsA promotes PCNA expression and migration of human trophoblast in a dose-associated manner. Blocking of the MAPK3/1 signal abrogated the enhanced PCNA expression and migration in trophoblasts by CsA. In addition, CsA increased the phosphorylation of NF-κB p65 and the inhibitor I-κB in human trophoblasts in a time-related manner. Pretreatment with MAPK3/1 inhibitor U0126 abrogated the phosphorylation of NF-κB p65 and I-κB. Accordingly, the CsA-induced enhancement of PCNA expression and migration in trophoblasts was also decreased. This CsA-induced enhancement in the expression and migration of trophoblasts was abolished by pretreatment with pyrrolidine dithiocarbamate, a specific NF-κB inhibitor. Thus, our results suggest that CsA promotes PCNA expression and migration of human trophoblasts via MAPK-mediated NF-κB activation.

Abstract
Interleukin-22 (IL-22) has been implicated as an important immune regulator in many physiologic and pathological processes, but little is known about the IL-22 in the fetal-maternal interface. In this study, we demonstrated that co-culture of decidual stromal cells (DSCs) and decidual natural killer (dNK) cells resulted in increased secretion of IL-22, compared to culture of DSCs or dNK cells alone. The trophoblast cell line, HTR8/SVneo, expresses IL-22 receptor α1 (IL-22R1). Combinant human (rh) IL-22 significantly promoted the proliferation and viability, and inhibited the apoptosis of HTR8/SVneo cells. By Western blotting and immunohistochemistry, we confirmed that villi expressed IL-22R1, and the villi from unexplained spontaneous miscarriage patients expressed reduced levels of IL-22R1 than those from normal early pregnancy. These findings indicate that the IL-22 secreted by DSCs and dNK might promote the survival of trophoblasts and participate in the maintenance of pregnancy by binding to the IL-22R1. The reduced level of IL-22/IL-22R1 in villi might be involved in the occurrence of spontaneous miscarriage.

Abstract
Chemokine CCL24 is the second member of eotaxins, a group of eosinophils' selectively chemoattractants. Via binding to its only receptor CCR3, CCL24 mainly mediates atopic disorders, parasitic infections and systemic diseases. It is well-known that CCR3 is expressed at the maternal-fetal interface; nevertheless whether CCL24 is located there and which role CCL24/CCR3 axis played is unclear. In this article, we assessed the expression of CCL24 and CCR3 in decidual stromal cells (DSCs) and trophoblasts, investigated the effects of DSCs-trophoblasts contact and pregnancy-associated hormones on the expression of CCR3 by DSCs, and last examined the role of trophoblasts-derived CCL24 on the proliferation, cell numbers and apoptosis of DSCs in vitro. We found that trophoblasts secrete chemokine CCL24, whereas DSCs express receptor CCR3. DSCs and trophoblasts co-culture had an raised level of CCL24 in culture supernatants, and the expression of CCR3 on DSCs was also obviously improved. Estrogen, progesterone and hCG up-regulated the expression of CCR3 on DSCs at appropriate concentration. CCL24 increased the proliferation and apoptosis of DSCs, whereas on the whole it promoted the number of DSCs. Thus, we conclude that by secreting CCL24 trophoblasts could promote the growth of DSCs; pregnancy associated environments such as DSCs-trophoblasts contact and hormones increased local CCL24/CCR3, which means a beneficial factor for the process of decidualization in human early pregnancy.

Abstract
Evidence for an immunosuppressive function of indoleamine 2,3-dioxygenase (IDO) has been accumulating. However, the unusual distribution of IDO1 in gynecologic cancer cells suggests that modulating immunity may not its only function. To clarify the physiological importance of IDO1 in endometriosis, a tumor-like benign disease, we have investigated the potential mechanism by which IDO1 modulated endometrial stromal cells (ESCs) proliferation and invasion. ESCs were obtained from 16 control women (normal) and 14 patients with ovarian endometrioma, then the normal ESCs were treated with plasmid pEGFP-N1-IDO1 or SD11-IDO1 short hairpin RNA (shRNA) alone, or in combination with c-Jun N-terminal kinase (JNK) inhibitor (SP600125), and subjected to cell viability, proliferation, apoptosis assay and Matrigel invasion assay. IDO1 mRNA expression was evaluated by quantitative real-time reverse transcription-polymerase chain reaction (real-time PCR), and protein levels of IDO1, survivin, protein 53 (p53), matrix metalloproteinase (MMP)-2, MMP-9, tissue-inhibitor of metalloproteinase-1 (TIMP-1) and cyclooxygenase-2 (COX-2) in IDO1-overexpressing and IDO1-deficiency ESCs were analyzed by in-cell Western. We found that IDO1 expression was higher in endometriosis-derived eutopic and ectopic ESCs, compared with endometriosis-free normal ESCs. As a result, IDO1-overexpression in ESCs was markedly linked to reduction of apoptosis and p53 expression, and upregulation of survival, proliferation, invasion, as well as expression of MMP-9, COX-2 expression, rather than expression of survivin, MMP-2 and TIMP-1. Reversely, JNK blockage could abrogate these alterations of ESCs in IDO1-overexpressing milieu, suggesting that JNK signaling pathway was indispensable for ESCs survival, proliferation and invasion enhanced by IDO1, which may contribute to the pathophysiology of endometriosis.

Abstract
Indoleamine 2,3-dioxygenase-1 (IDO1) is an intracellular enzyme that catalyses essential amino acid tryptophan along the kynurenine pathway. The aim of this study was to determine the impact of IDO1 expression on the biological characteristic of the endometrial stromal cells (ESCs). IDO1, cyclooxygenase-2 (COX-2) and matrix metalloproteinases (MMPs) in endometriotic ectopic stromal cells, endometriosis-derived eutopic stromal cells and normal ESCs (control) were detected by the in-cell Western analysis. After being treated with lipopolysaccharide, levo-1-methyl-tryptophan (L-1-MT) alone or a combination, a comparative analysis of the above protein expression was evaluated. The effects of IDO1 on ESCs proliferation, adhesion and invasion were detected through ELISA, adhesion assay and Matrigel invasion assay, respectively. The results showed that, contrary to healthy ESCs from control women, the expression of IDO1 was significantly higher in eutopic and ectopic ESCs obtained from women with endometriosis. Inhibition of IDO1 by L-1-MT suppressed the expression of COX-2 and MMP-9 in ESCs. It could also decrease the ESCs proliferation, adhesion and invasion, while stimulating ESCs decidualization. Thus, IDO1 is possibly involved in endometriosis pathogenesis via promoting COX-2 and MMP-9 expression and regulation of ESCs biological characteristics. The information may be useful for developing a new therapeutic strategy for endometriosis.

Abstract
BACKGROUND Chemokine CXCL8 (also known as IL-8) has been identified as a potential regulator of endometrial stromal cells (ESCs), but it is unclear how CXCL8 regulates the survival of ESCs in the pathogenesis of endometriosis. METHODS We assessed the secretion of CXCL8 by enzyme-linked immunosorbent assays and the expression of its receptors, CXCR1 and CXCR2, by in-cell Western assay and immunohistochemistry. The effects of CXCL8 on the activation or expression of various cell mediators were also investigated by in-cell Western assay. The effects of CXCL8 on the proliferation, growth and apoptosis of ESCs in vitro were assessed by BrdU assays, cell counts and annexin V labeling, respectively. RESULTS Secretion of CXCL8 and expression of CXCR1 in the eutopic ESCs from women with endometriosis were significantly higher than that in control ESCs, but the expression of CXCR2 showed no significant difference between these two cell types. CXCL8 stimulated proliferation and growth and reduced apoptosis of ESCs in an autocrine manner, and these effects were abolished by anti-human CXCL8 and CXCR1 neutralizing antibodies and by a PI3K/Akt inhibitor. Moreover, CXCL8 up-regulated the expression of the anti-apoptotic proteins, survivin and Bcl-2, inhibited the expression of the Phosphatase and tensin homolog (PTEN) and activated the phosphorylation of Akt. CONCLUSIONS This study suggests that CXCL8 and CXCR1 are involved in the pathogenesis of endometriosis by up-regulating proliferation and growth and restricting apoptosis in ESCs by activating the PTEN/Akt pathway and mediating the expression of survivin and Bcl-2.

Abstract
Our previous study has demonstrated that thymic stromal lymphopoietin (TSLP) stimulates trophoblast proliferation and invasion, suggesting TSLP plays an important role in the placentation in early human pregnancy, but the intracellular molecular mechanism is currently unknown. The present study is undertaken to investigate whether the STAT3-c-Myc signaling pathway is involved in TSLP-mediated trophoblast proliferation. Primary human first-trimester trophoblasts were treated with TSLP only, or TSLP combined with different signaling inhibitors (STAT3, STAT5, AKT, and ERK). The levels of STAT3 tyrosine phosphorylation and c-Myc expression were determined by using Western blot analysis, and the proliferation of trophoblasts was analyzed by BrdU cell proliferation assay. JEG-3 cells were transfected with siRNA targeting to c-Myc, and the proliferation was determined in JEG-3 cells treated with TSLP only, or TSLP combined with c-Myc silencing. It was revealed that treatment with TSLP significantly enhanced STAT3 phosphorylation and c-Myc expression in human trophoblasts. The effect of TSLP upregulation on trophoblast proliferation was abrogated completely by either STAT3 inhibitor or c-Myc siRNA silence. We further found that the upregulation of TSLP on c-Myc expression was abrogated completely by the STAT3 inhibitor, which suggests that the intracellular STAT3 phosphorylation is an upstream signal of c-Myc expression in the TSLP-stimulated trophoblast proliferation. These results suggest that TSLP may upregulate c-Myc expression through activation of STAT3 pathway, thereby inducing trophoblast proliferation.

Abstract
BACKGROUND Previous investigations have demonstrated a relatively low incidence of stroke among young women, though both pregnancy and delivery can substantially increase the risk. Cerebral venous thrombosis may manifest different characteristics during pregnancy and postpartum as a result of their specific physiological statuses. This study aimed to identify the clinical manifestations, diagnosis, treatment, and prognosis of cerebral venous thrombosis during pregnancy and postpartum. METHODS We conducted a retrospective analysis of 22 patients with cerebral venous thrombosis who were assigned to either group A (during pregnancy) or group B (during postpartum). The relevant risk factors, initiation and development of the disease, clinical presentations, diagnosis, treatment, and prognosis were compared between the two stages. RESULTS Cerebral venous thrombosis occurred during both pregnancy and postpartum, but was more common postpartum. Patients in group A had a longer hospitalization period than those in group B. Confirmed predisposing factors in 85.7% of patients of group A were dehydration, infection, and underlying cerebrovascular disorders. No obvious predisposing factors were identified in group B. The most frequent symptom was headache, with epileptic seizures, hemiparalysis and aphasia being less frequent symptoms. Focal neurological symptoms (P = 0.022) and cerebral infarction (P = 0.014) occurred more frequently in group A than in group B. Anticoagulation therapy proved to be safe for cerebral venous thrombosis patients during puerperium, regardless of parenchymal hemorrhage. However, more attention should be paid to spontaneous in-site placental hemorrhage in pregnant patients. Both groups had similar prognoses (P = 1.000), with 36.3% patients suffering from consequential dysfunction or recurrent intracranial hypertension. Delayed diagnosis was associated with a poorer prognosis. CONCLUSIONS Cerebral venous thrombosis manifests different clinical characteristics during pregnancy and postpartum, though both have a good prognosis. Early diagnosis and prompt anticoagulation therapy are essential.

Abstract
PROBLEM To evaluate whether the association of the costimulatory signal regulation with T helper 1/T helper 2 (Th1/Th2) bias at maternal-fetal interface in human pregnancy loss. METHOD OF STUDY The expression of CD80 and CD86 in decidual tissues and CD28 and cytotoxic T-lymphocyte antigen-4 (CTLA-4) in the decidual T cells was compared between normal early pregnancy and miscarriage by qPCR and Western blot. The cytokine production in decidual T cells was performed by flow cytometry. The correlation of costimulatory molecule expression with Th1/Th2 cytokines was analyzed. RESULTS The CD80 mRNA and protein expression showed no significant difference between normal pregnancy and miscarriage. An increase in the expression of CD28 and CD86 was accompanied by a decrease in the expression of CTLA-4 in miscarriage in comparison with the early pregnancy. The higher expression of interleukin (IL)-2 and interferon-γ (IFN-γ), and lower expression of IL-4 and IL-10 in the decidual T cells were present in miscarriage. A correlation analysis showed a significant positive correlation of CD86 and CD28 expression with the Th1 cytokine production (IL-2 and IFN-γ), a significant negative correlation of CTLA-4 expression with the Th1 cytokine production. CONCLUSION The upregualtion of costimulatory signals on T cells might form an abnormal immune microenvironment, a shift to Th1 responses, at maternal-fetal interface, which leads to human miscarriage.

Abstract
A pregnancy is associated with modifications in the immune status of the mother, but the mechanisms are not well understood. Several observations have indicated that CD28/CTLA-4 and B7-1/B7-2 are involved in the maternal-fetal immune regulation. This review aims to recapitulate our current knowledge concerning the role of CD28/CTLA-4 and B7-1/B7-2 in maternal-fetal immune regulation. Several studies suggest that up-regulation of B7-2 and/or CD28 and/or down-regulation of CTLA-4 are correlated with the occurrence of pregnancy loss. Therefore, an accurate expression of costimulatory molecules at the maternal-fetal interface may ensure that the decidual cells do not elicit a 'danger' signal to the maternal immune system, perhaps instead contributing to the establishment of immune tolerance in vivo. It is showed that costimulation blockade with anti-B7 mAbs results in altered allogeneic T-cell response and overcomes increased maternal rejection to the fetus, which improves fetus growth in the abortion-prone system. These findings suggest that the anti-B7-treated T cells not only function as potent suppresser cells but also exert immunoregulatory effect on the maternal T cells. This procedure might be potentially useful to immunotherapy for human recurrent spontaneous abortion.

Abstract
BACKGROUND Thymic stromal lymphopoietin (TSLP) is a novel cytokine that triggers the dendritic cell-mediated T(H)2 response and regulatory T cell expansion. The aim of this study is to evaluate whether TSLP and TSLP receptor (TSLPR) are expressed in primary human extravillous trophoblast (EVT), how proimflammatory cytokines (tumor necrosis factor (TNF)-alpha, IL-1beta), T(H)2 and T(H)3 cytokines (IL-4, TGF-beta) and pregnancy-associated hormones regulate TSLP production by EVT and whether the SLP-TSLPR interaction affects the biological behavior of trophoblsts. METHODS We assessed TSLP mRNA and protein expression by real-time RT-PCR, ELISA and immunochemistry, respectively. We further investigated effects of TSLP on the proliferation and invasion of trophoblast cells in vitro. RESULTS The primary EVTs constitutively expressed TSLP and TSLPR. IL-4 and TNF-alpha or pregnancy-associated hormones result in a significant increase in TSLP mRNA expression and protein release from EVT, and TSLP promotes primary EVT proliferation and invasion in vitro. CONCLUSIONS This study has demonstrated that the first-trimester human trophoblast cells express TSLP and TSLPR, that cytokine milieu which mimics the maternal-fetal interface modulates expression of TSLP in trophoblast and that TSLP stimulates trophoblast proliferation and invasion. This suggests that TSLP plays an important role in human EVT invasion and placentation in human early pregnancy.

Abstract
PROBLEM To investigate the Th1/Th2 cytokine changes in abortion-prone recipient mice adoptively transferred by the paternal antigen-hyporesponsive T cells. METHOD OF STUDY The paternal antigen-hyporesponsive T cells were generated by the anti-B7 monoclonal antibody (mAb) treatment and adoptively transferred into pregnant CBA/J mice of abortion-prone matings on day 4 of gestation. The intracellular expressions of Th1 cell-derived cytokine, tumor necrosis factor-alpha, gamma-interferon and interleukin-2 (IL-2) and Th2 cell-derived cytokine, IL-4 and IL-10 in the maternal spleen were analyzed by flow cytometry, and secretions of the Th1 and Th2 cytokines in supernatant of the feto-placental unit culture were analyzed by an enzyme-linked immunosorbent assay. RESULTS Our findings showed the increased secretion of Th1 cytokines and the decreased secretion of Th2 cytokines in abortion-prone matings. Treatment with anti-B7 mAbs on day 4 of gestation enhanced Th2 and reduced Th1 cytokine production in abortion-prone matings. Similarly, adoptive transfer of paternal antigen-hyporesponsive T cells induced maternal tolerance to the fetus and displayed a Th2 bias both in the peripheral lymphocytes and at the materno-fetal interface of the abortion-prone matings. CONCLUSIONS These findings indicate that the Th2 cytokine bias and an increase in fetal viability induced by the anti-B7 mAb treatment can be transferred to other pregnant mice of the abortion-prone matings.
