  • Chronic endometritis in patients with unexplained infertility: Prevalence
           and effects of antibiotic treatment on spontaneous conception
    • Authors: Ettore Cicinelli; Maria Matteo, Giueseppe Trojano, Paola C. Mitola, Raffaele Tinelli, Amerigo Vitagliano, Francesco M. Crupano, Achiropita Lepera, Giuseppe Miragliotta, Leonardo Resta
      Abstract: ProblemThe correlations between chronic endometritis and unexplained infertility are unexplored.Method of StudyWe performed a retrospective study on consecutive patients referred to our hysteroscopy service due to unexplained infertility. All women underwent endometrial sampling with histological and cultural examinations. If chronic endometritis was diagnosed, patients received antibiotic therapy, and chronic endometritis resolution was subsequently ascertained by histological examination. We aimed to estimate chronic endometritis prevalence and the effects of antibiotic therapy on spontaneous conception during the year following hysteroscopy.ResultsA total number of 95 women were included. Pooled prevalence of chronic endometritis was 56.8%. Antibiotic therapy resulted in chronic endometritis resolution in 82.3% of patients, while in 17.6% disease was persistent. Women with cured chronic endometritis showed higher pregnancy rate and live birth rate in comparison with both women with persistent disease and women without chronic endometritis diagnosis (pregnancy rate = 76.3% vs 20% vs 9.5%, P

  • Low molecular weight heparin and aspirin exacerbate human endometrial
           endothelial cell responses to antiphospholipid antibodies
    • Authors: Zola Chihombori Quao; Mancy Tong, Elena Bryce, Seth Guller, Lawrence W. Chamley, Vikki M. Abrahams
      Abstract: ProblemWomen with antiphospholipid antibodies (aPL) are at risk for pregnancy complications despite treatment with low molecular weight heparin (LMWH) or aspirin (ASA). aPL recognizing beta2 glycoprotein I can target the uterine endothelium, however, little is known about its response to aPL. This study characterized the effect of aPL on human endometrial endothelial cells (HEECs), and the influence of LMWH and ASA.Method of studyHEECs were exposed to aPL or control IgG, with or without low-dose LMWH and ASA, alone or in combination. Chemokine and angiogenic factor secretion were measured by ELISA. A tube formation assay was used to measure angiogenesis.ResultsaPL increased HEEC secretion of pro-angiogenic VEGF and PlGF; increased anti-angiogenic sFlt-1; inhibited basal secretion of the chemokines MCP-1, G-CSF, and GRO-α; and impaired angiogenesis. LMWH and ASA, alone and in combination, exacerbated the aPL-induced changes in the HEEC angiogenic factor and chemokine profile. There was no reversal of the aPL inhibition of HEEC angiogenesis by either single or combination therapy.ConclusionBy aPL inhibiting HEEC chemokine secretion and promoting sFlt-1 release, the uterine endothelium may contribute to impaired placentation and vascular transformation. LMWH and ASA may further contribute to endothelium dysfunction in women with obstetric APS.

  • Genetic and epigenetic regulation of major histocompatibility complex
           class I gene expression in bovine trophoblast cells
    • Authors: Bi Shi; Aaron J. Thomas, Abby D. Benninghoff, Benjamin R. Sessions, Qinggang Meng, Parveen Parasar, Heloisa M. Rutigliano, Kenneth L. White, Christopher J. Davies
      Abstract: ProblemThe regulatory mechanisms governing differential expression of classical major histocompatibility complex (MHC) class I (MHC-Ia) and non-classical MHC class I (MHC-Ib) genes are poorly understood.Method of studyQuantitative reverse transcription- polymerase chain reaction (PCR) was used to compare the abundance of MHC-I transcripts and related transcription factors in peripheral blood mononuclear cells (PBMC) and placental trophoblast cells (PTC). Methylation of MHC-I CpG islands was detected by bisulfite treatment and next-generation sequencing. Demethylation of PBMC and PTC with 5′-aza-deoxycytidine was used to assess the role of methylation in gene regulation.ResultsMHC-I expression was higher in PBMC than PTC and was correlated with expression of IRF1, class II MHC transactivator (CIITA), and STAT1. The MHC-Ia genes and BoLA-NC1 were devoid of CpG methylation in PBMC and PTC. In contrast, CpG sites in the gene body of BoLA-NC2, -NC3, and -NC4 were highly methylated in PBMC but largely unmethylated in normal PTC and moderately methylated in somatic cell nuclear transfer PTC. In PBMC, demethylation resulted in upregulation of MHC-Ib by 2.8- to 6-fold, whereas MHC-Ia transcripts were elevated less than 2-fold.ConclusionDNA methylation regulates bovine MHC-Ib expression and is likely responsible for the different relative levels of MHC-Ib to MHC-Ia transcripts in PBMC and PTC.qRT-PCR analysis of bovine MHC-I and transcription factor gene expression in PBMC and PTC. Data were normalized to GAPDH. The heatmap shows the fold change of gene expression relative to the average for the AI PTC samples.

      Abstract: ProblemHow is the role of inhibitor of apoptosis proteins (IAPs) in the development of murine endometriosis lesions'Method of studyBALB/c female mice (n = 36) were used for the murine endometriosis model. Endometriotic lesions were surgically induced in mice by transplanting mouse uterine tissue. After 4 weeks of IAP antagonist (BV6) treatment, the expression of inflammatory factors in the implants was evaluated using real-time RT-PCR. Inflammatory state, angiogenic activity, and nuclear factor-kappa B (NF-κB) activation were assessed by immunohistochemical staining.ResultsThe number, size, and level of inflammatory cytokines (Vegf, Il-6, Ccl-2, Lif) gene expression in the murine endometriosis-like lesions were reduced by BV6 treatment. BV6 repressed the intensity and rate of positive cells of CD3, F4/80, and PECAM immunostaining; in addition, the expression of NF-κB p65 and phospho-NF-κB p65 was also attenuated.ConclusionInhibitor of apoptosis proteins antagonist represses the inflammation status of murine endometriosis-like lesions viaNF-κB pathway. IAPs may be a novel therapeutic target for endometriosis.

  • Medroxyprogesterone acetate-treated human, primary endometrial epithelial
           cells reveal unique gene expression signature linked to innate immunity
           and HIV-1 susceptibility
    • Authors: Matthew W. Woods; Muhammad Atif Zahoor, Sara Dizzell, Chris P. Verschoor, Charu Kaushic
      Abstract: ProblemMedroxyprogesterone acetate (MPA), a progestin-based hormonal contraceptive designed to mimic progesterone, has been linked to increased human immunodeficiency virus (HIV-1) susceptibility. Genital epithelial cells (GECs) form the mucosal lining of the female genital tract (FGT) and provide the first line of protection against HIV-1. The impact of endogenous sex hormones or MPA on the gene expression profile of GECs has not been comprehensively documented.Method of studyUsing microarray analysis, we characterized the transcriptional profile of primary endometrial epithelial cells grown in physiological levels of E2, P4, and MPA.ResultsEach hormone treatment altered the gene expression profile of GECs in a unique manner. Interestingly, although MPA is a progestogen, the gene expression profile induced by it was distinct from P4. MPA increased gene expression of genes related to inflammation and cholesterol synthesis linked to innate immunity and HIV-1 susceptibility.ConclusionThe analysis of gene expression profiles provides insights into the effects of sex hormones and MPA on GECs and allows us to posit possible mechanisms of the MPA-mediated increase in HIV-1 acquisition.Treatment of human endometrial epithelial cells with the hormonal contraceptive, Medroxyprogesterone acetate results in a unique gene expression signature linked to innate immunity and HIV-1 susceptibility.

  • Breastfeeding and autoimmunity: Programing health from the beginning
    • Authors: Vânia Vieira Borba; Kassem Sharif, Yehuda Shoenfeld
      Abstract: Breast milk is not only a completely adapted nutrition source for the newborn but also an impressive array of immune-active molecules that afford protection against infections and shape mucosal immune responses. Decisive imprinting events might be modulated during the first months of life with potential health long-term effects, enhancing the importance of breastfeeding as a major influence on the immune system correct development and modifying disease susceptibility. The aim of this review was to clarify the link between breastfeeding and autoimmune diseases, inquiring the related mechanisms, based on data available in the literature. Being breastfed was associated with a lower incidence of diabetes, celiac disease, multiple sclerosis and asthma, explained by the protection against early infections, anti-inflammatory properties, antigen-specific tolerance induction, and regulation of infant's microbiome. The protective role of human milk in idiopathic juvenile arthritis, rheumatoid arthritis, and inflammatory bowel diseases remains controversial. On the other hand, the breastfeeding mother faces a health-challenging period in life. High levels of prolactin may lead either to the development of autoimmune diseases in susceptible mothers or exacerbations of current immune-mediated disorders. These features raise the question if mothers with autoimmune diseases, mainly systemic lupus erythematosus, should avoid breastfeeding.

  • Gestational tissue inflammatory biomarkers at term labor:
           A systematic review of literature
    • Authors: Emily E. Hadley; Lauren S. Richardson, Maria R. Torloni, Ramkumar Menon
      Abstract: Parturition at term is characterized by inflammatory overload in both feto-maternal tissues. Despite the large number of individual studies on changes in inflammatory biomarkers linked to labor, a comprehensive profile of them in each of the uterine compartments is not available to better understand their mechanistic contributions to labor. This systematic review investigated the pro- and anti-inflammatory biomarkers reported in intra-uterine tissues (amnion, chorion, decidua, placenta, and myometrium) at term labor. We conducted a systematic review of studies on pro- and anti-inflammatory biomarkers (mRNA and/or protein) reported in feto-maternal tissues during normal human term labor, published in English (1980-2016), in 3 electronic data bases. From a total of 3712 citations, 172 were included for final review. Each tissue expresses a unique set of biomarkers at the time of term labor, but there is significant overlap between tissues. All tissues had IL-6, IL-8, IL-1β, COX-2, PGE-2, TNF-α, and hCAP18 in common at term labor. Common and unique inflammatory biomarkers are expressed in various feto-maternal compartments at term labor. Increase in pro-inflammatory markers in all gestational tissue signifies their harmonious functional role in promoting labor. Anti-inflammatory markers at term labor are hardly reported.

  • The immune profile induced is crucial to determine the effects of
           immunocastration over gonadal function, fertility, and GnRH-I expression
    • Authors: Daniela Siel; Alexandra Loaiza, Sonia Vidal, Mario Caruffo, Rodolfo Paredes, Galia Ramirez, Lisette Lapierre, Cristóbal Briceño, Oliver Pérez, Leonardo Sáenz
      Abstract: ProblemImmunocastration or vaccination against the GnRH-I hormone is a promising alternative to reproductive control in different animal species. Given the low immunogenicity of this hormone, the use of adjuvants becomes necessary.Method of StudyThis study evaluated the effects of three adjuvants that induce different immune response profiles over gonadal function, fertility, and expression of GnRH-I. Female mice (n = 6) were vaccinated at days 1 and 30 with a recombinant antigen for immunocastration and different adjuvants that induced preferentially Th1/Th2, Th2, and Th1 immune profiles.ResultsTh1/Th2 response is the most efficient to block reproductive activity in vaccinated animals, reducing the number of luteal bodies and pre-ovulatory follicles. Th2 and Th1/Th2 responses induced an increase in GnRH-I at the hypothalamus.ConclusionThe immune profile induced by different adjuvants is essential on the effects over fertility, gonadal function, and hypothalamic GnRH-I expression in immunocastrated animals.In female mice vaccinated with a recombinant antigen for immunocastration and different adjuvants that induced preferentially Th1/Th2, Th2, and Th1 immune profiles, the effects of vaccination over gonadal function, fertility, and expression of GnRH-I were evaluated.

      Abstract: ProblemDecidual immune dysregulation is thought to underlie major pregnancy disorders; however, incomplete understanding of the decidual immune interface has hampered the mechanistic investigation.Method of studyHuman term decidua was collected, and single-cell phenotypic information was acquired by highly polychromatic flow cytometry. Cellular identity analysis was performed with t-distributed stochastic neighbor embedding, DensVM clustering, and matched to CellOntology database.ResultsTraditional analytical methods validated known cellular T and dendritic cell subsets in human term decidua. Computational analysis revealed a complex and tissue-specific decidual immune signature in both the innate and adaptive immune compartments.ConclusionPolychromatic flow cytometry with a streamlined computational analysis pipeline is a feasible approach to comprehensive immunome mapping of human term decidua. As an unbiased, standardized method of investigation, computational flow cytometry promises to unravel the immune pathology of pregnancy disorders.Use of high dimensional flow cytometry with operator-independent machine learning to comprehensively map T cell populations at the maternal-fetal interface. t-SNE map generated from pre-gated CD3+ cells from decidua basalis, decidua parietalis, and PBMCs (top) and manually gated subsets overlaid onto total CD3+ cells (bottom). Analysis revealed a unique immune signature, characteristic of term human decidua.

      Abstract: ProblemThe endothelial glycocalyx (EGX) plays an important role in vascular integrity. Recently, increased levels of EGX components were detected in the circulating blood of healthy pregnant women and were related to the increased tendency to edema formation during gestation. However, the EGX has not yet been systematically studied in non-pregnant women during ovulatory cycles.Method of studySerum levels of EGX components syndecan-1, heparan sulfate, and hyaluronan in healthy women (n = 16) at 3 phases of the ovulatory cycle (early follicular phase, at ovulation, and mid-luteal phase) were compared with a control group of healthy men (n = 10). Using immunofluorescence microscopy in cultured human umbilical vein endothelial cells, the effects of progesterone and estrogen on the EGX were measured.ResultsSyndecan-1 increased from 11.1 ± 2.4 ng/mL at ovulation to 12.6 ± 2.3 ng/mL in mid-luteal phase (P = .031) and of heparan sulfate from 663 ± 35 ng/mL to 782 ± 55 ng/mL (P = .011). In contrast to estrogen, there was a detrimental effect of progesterone on the EGX in HUVECs.ConclusionThe relationship between the natural menstrual cycle and the EGX as an indicator of vascular permeability may provide a new explanation for premenstrual edema in healthy women. This may be an attendant phenomenon of a regular physiological process, the hormonal downregulation of the vascular barrier during pregnancy.

  • Modulation of Th17 and regulatory T-cell responses during murine pregnancy
           contributes to increased maternal susceptibility to Salmonella Typhimurium
           infection
    • Authors: Gerard Agbayani; Kristina Wachholz, Anindita Chattopadhyay, Komal Gurnani, Shawn P. Murphy, Lakshmi Krishnan
      Abstract: ProblemSalmonella Typhimurium (S. Tm) infection in pregnant mice results in massive placental infection, fetal loss, and exacerbated systemic infection. The Th17 host response can aid control of S. Tm infection, whereas successful pregnancy correlates to a dampened inflammatory and enhanced regulatory T-cell (Treg) response.Method of studyMice were infected systemically with S. Tm and tissue bacterial burden, splenic Th17 and Treg cell numbers, and serum cytokines were analyzed. Splenic and/or placental mRNA expression of IL-17A, RORγ-t, IL-10, and TNF was determined. The effects of in vivo CD25+ cell depletion and TLR4 blockade on the course of S. Tm infection and Th17 response were determined.ResultsEnhanced S. Tm burden in pregnant mice was associated with time-dependent increased serum inflammatory cytokines. In vivo, TLR4 blockade reduced splenic S. Tm burden, suggesting detrimental TLR4-mediated inflammation. However, the splenic and placental Th17 response was reduced in S. Tm-infected pregnant mice relative to non-pregnant controls. Alternatively, there was an increase in splenic Treg frequency in pregnant mice and depletion of this subset reduced bacterial burden and increased the Th17 response.ConclusionDownregulation of Th17 cell responses by Tregs during pregnancy potentially contributes to exacerbation of S. Tm infection in pregnant mice.

      Abstract: ProblemThe mechanisms underlying the regulation of decidual natural killer cells (dNKs) at the maternal-fetal interface are unclear.Method of studyPrimary trophoblasts (TROs), decidual stromal cells (DSCs), and dNKs were cocultured, and responses to LAIR-2 (LAIR-1 inhibitor) and P4H shRNA (collagen inhibitor) were studied.ResultsCoculture of dNKs with primary TROs/DSCs resulted in downregulation of Th1 cytokine production by dNKs. These effects were abrogated by LAIR-2 and P4H shRNA. LAIR-1 binds to SHP-1, which in turn binds to JAK1 and JAK2. Further, the phosphorylation of STAT1/STAT4 and the expression of the downstream transcription factors T-bet and Helios in dNKs were decreased by collagen treatment and primary TROs/DSCs coculture.ConclusionThe JAK-STAT pathway and its downstream transcription factors T-bet and Helios are involved in the regulation of dNK function by collagen/LAIR-1 interaction, and this signaling mechanism may contribute to the maintenance of immune tolerance at the maternal-fetal interface.Signaling pathway for the regulation of dNKs at the maternal-fetal interface via collagen/LAIR-1 interaction

      Abstract: ProblemDifferences in circulating (peripheral) and mucosal T-cell phenotypes in chlamydia-infected women remain largely unknown.Method of studyThirteen paired mononuclear cell specimens from blood and cervicovaginal lavages collected from chlamydia-infected women were stained and analyzed using ten-color cell surface flow cytometry for T-cell distribution, activation status, homing, and T helper (Th)-associated chemokine receptors (CKRs).ResultsA higher proportion of genital mucosal T-cells were activated (CD38+HLA-DR+) and expressed CCR5 and Th1-associated CKR CXCR3+CCR5+ compared to peripheral T-cells, but a lower proportion of mucosal T-cells expressed homing CKR CCR7, Th-2 associated CKR CCR4, and CXCR3+CCR4+ for both T-cell subsets.ConclusionT-cell phenotypes differed in the peripheral vs genital mucosa compartments in chlamydia-infected women. As chlamydia infects mucosal epithelial cells, the finding of a higher frequency of activated T-cells and Th-1 phenotypes in the mucosa likely reflects an adaptive immune response to infection.

      Abstract: ProblemTo determine if altered trophoblast CD200 and CD200R expressions promote inflammatory cytokine production in preeclamptic placentas.Methods of studyPlacental tissue CD200 and CD200R expressions were determined by immunostaining. Tissue sections from first-, second-, and third-trimester, normal term, and preeclamptic placentas were used. CD200 and CD200R expressions and cytokine production of TNFα, sTNFR1, INFγ, IL-4, IL-6, IL-8, and IL-10 were determined in trophoblasts from normal and preeclamptic placentas and in normal trophoblasts transfected with CD200 siRNA.ResultsCD200, but not CD200R, expression was significantly reduced in trophoblasts from preeclamptic compared to normal placentas. Trophoblast from preeclamptic placentas and trophoblast transfected with CD200 siRNA produced significantly more TNFα, sTNFR1, IL-6, and IL-8, but significantly less IL-10, than trophoblasts from normal control placentas.ConclusionDownregulation of CD200 expression resulted in an imbalance of increased Th1 cytokine and decreased Th2 cytokine production in placental trophoblasts in preeclampsia.

    • Authors: Anita Barišić; Nina Pereza, Alenka Hodžić, Saša Ostojić, Borut Peterlin
      Abstract: ProblemAberrant DNA methylation has been suggested as a potential cause of recurrent spontaneous abortion (RSA). Considering the growing evidence on the important roles of DNA methylation in gametogenesis and early pregnancy, we investigated the potential association of DNA methyltransferase gene polymorphisms (DNMT1 rs2228611, DNMT3A rs1550117, DNMT3B rs1569686) with RSA in Slovenian reproductive couples.Method of studyA total of 146 couples with ≥3 consecutive spontaneous abortions and 149 control women and men with ≥2 normal pregnancies were included. Genotyping was performed using PCR-RFLP methods.ResultsWe found a statistically significant higher frequency of the DNMT3B rs1569686 GG genotype (X2=7.37;P = .025) and G allele (X2 = 6.33;P = .012) in RSA women compared with controls. Moreover, the odds for RSA in women were increased under the recessive genetic model (GGvsTG+TT: OR=1.92; 95% CI=1.18-3.09; P = .008).ConclusionDNMT3B rs1569686 gene polymorphism in women might be a genetic marker for the susceptibility to RSA.

    • Authors: Lucy Rudo Mukura; Danica K. Hickey, Marta Rodriguez-Garcia, John V. Fahey, Charles R. Wira
      Abstract: ProblemChlamydia trachomatis infection is the most common sexually transmitted bacterial infection worldwide and known to increase the risk for HIV acquisition. Few studies have investigated how infection of epithelial cells compromises barrier integrity and antimicrobial response.Method of studyECC-1 cells, a human uterine epithelial cell line, were treated with live and heat-killed C. trachomatis. Epithelial barrier integrity measured as transepithelial resistance (TER), chemokines antimicrobial levels, and antimicrobial mRNA expression was measured by ELISA and Real-time RT-PCR.ResultsEpithelial barrier integrity was compromised when cells were infected with live, but not with heat-killed, C. trachomatis. IL-8 secretion by ECC-1 cells increased in response to live and heat-killed C. trachomatis, while MCP-1, HBD2 and trappin2/elafin secretion decreased with live C. trachomatis.ConclusionLive C. trachomatis suppresses ECC-1 innate immune responses by compromising the barrier integrity, inhibiting secretion of MCP-1, HBD2, and trappin-2/elafin. Differential responses between live and heat-killed Chlamydia indicate which immune responses are dependent on ECC-1 infection rather than the extracellular presence of Chlamydia.

    • Authors: Tao Zhang; Chunyu Huang, Yan Du, Ruochun Lian, Meilan Mo, Yong Zeng, Gil Mor
      Abstract: ProblemEffective therapy for endometrial receptivity of patients with repeated embryo implantation failure (RIF) is far undeveloped. Whether intrauterine perfusion of dexamethasone (DXM), local administration of drugs with less systematic side-effects, benefit for embryo implantation by suppressing uterine NK (uNK) cells to improve endometrial receptivity remains unknown.Method of studyWomen with RIF were analyzed for the correlation between the percentage of uNK cells during implantation window and following clinical pregnancy rate to determine the appropriate range of uNK for embryo implantation. Women with RIF and extremely increased uNK cells were treated with transvaginal intrauterine perfusion of DXM. Quantification of uNK cells before and after this treatment was analyzed by immunohistochemistry staining for understanding potential underlying mechanism. Pregnancy outcome was evaluated for the efficiency and safety of this novel therapy.ResultsThe clinical pregnancy rate was decreased if the percentage of uNK cells was higher than the 75th percentile (18.06%), which was considered as the cutoff value for increased uNK cells. All eight patients with increased uNK cells responded to DXM-induced decrease on uNK cells number, and seven got clinical pregnancy. Three delivered with a healthy baby at term without any pregnancy complication and three achieved an ongoing pregnancy, but one suffered from early miscarriage.ConclusionWe report for the first time the beneficial effect of intrauterine perfusion of DXM for patients with RIF characterized by high number of uNK cells. The potential mechanism is downregulation of the proportion of uNK cells, which may improve endometrial receptivity and enhance embryo implantation.

           microRNA, let-7f-1 in human endocervical cells
    • Authors: Kanchana Ayyar; Kudumula Venkata Rami Reddy
      Abstract: ProblemIn endocervical epithelial cells (End1/E6E7), miRNA let-7f plays an important role in the control of innate immunity. The underlying molecular mechanism for let-7f regulation in these cells remains largely unclear.Methods of studylet-7f was knocked down in End1/E6E7 cells using siRNA, and differential gene expression was analyzed by microarray. Differentially expressed genes were validated by qPCR and Western blot. Expression of let-7f was studied by qPCR after inhibition of C/EBPβ with betulinic acid (BA) and pCMVβ plasmid and after overexpression of C/EBPβ with pCMVβ+ plasmid. ChIP assay was performed to confirm binding of C/EBPβ to let-7f promoter. Levels of Lin28A/B were checked by qPCR after similar treatment.Resultslet-7f knockdown (KD) affects the expression of many transcription factors (eg, C/EBPβ) which are important regulators of immune responses. We observed let-7f-1 promoter to contain 6 C/EBPβ binding sites. KD of C/EBPβ led to decreased let-7f expression while overexpression of C/EBPβ increased its expression. Treatment of End1/E6E7 cells with TLR-3 ligand, poly(I:C) increased binding of C/EBPβ at binding sites 3, 5, and 6. Expression of Lin28A/B also changed upon inhibition and overexpression of C/EBPβ. Its expression is opposite to that of let-7f in End1/E6E7 cells.Conclusionlet-7f-1 is a direct target of transcription factor, C/EBPβ in End1/E6E7 cells.

Here, we analyze the percentage of CD4+ CD25high FOXP3+, CD4+ CD25low FOXP3+, and CD4+ FOXP3+ Tregs, in the umbilical cord blood of babies born to mothers with and without preeclampsia.Method of studyThe percentage of umbilical cord blood CD4+ CD25high FOXP3+, CD4+ CD25low FOXP3+, and CD4+ FOXP3+ Tregs were analyzed by flow cytometry.ResultsCD4+ CD25high FOXP3+ Treg (%) and CD4+ FOXP3+ Treg (%) were significantly lower, while CD4+ CD25low (%) was significantly higher in umbilical cord blood of babies born to preeclamptic mothers.ConclusionPreeclampsia is associated with immune dysregulation which leads to a deficiency in Treg (CD4+ CD25high FOXP3+) in the umbilical cord blood of babies born to preeclamptic mothers.

  • Expansion of CD4 phenotype among CD160 receptor-expressing lymphocytes in
           murine pregnancy
    • Authors: Matyas Meggyes; Laszlo Szereday, Pal Jakso, Barbara Bogar, Agnes Bogdan, Jasper Nörenberg, Eva Miko, Aliz Barakonyi
      Abstract: ProblemCD160, a cell surface co-receptor, is capable of up- or downregulating cell proliferation, cytotoxicity or cytokine production on lymphocytes. Our aim was to investigate CD160+ lymphocytes in the periphery and at the maternal-foetal interface during murine pregnancy.Method of studyCD4+, CD8+ and gamma/delta T-cell phenotype, TIM3 co-expression and cytotoxic activity of CD160+ lymphocytes of pregnant BALB/c mice were analysed by flow cytometry.ResultsThe percentage of CD160+ lymphocytes in the decidua was unchanged compared to non-pregnant endometrium; however, the ratio of CD4+ cells within the CD160 population was significantly increased. The co-expression of TIM3 co-inhibitory molecule and cytotoxicity of CD160+ cells were increased in the decidua.ConclusionThe expansion of CD4-expressing CD160+ decidual lymphocytes is a new observation suggesting a potential regulatory role of T-cell function during mouse pregnancy. The altered immunological character of CD160+ lymphocytes could play a role in the maintenance of murine pregnancy.

  • Undifferentiated connective tissue diseases and adverse pregnancy
           outcomes. An undervalued association'
    • Authors: Arsenio Spinillo; Fausta Beneventi, Roberto Caporali, Veronique Ramoni, Carlomaurizio Montecucco
      Abstract: Undifferentiated connective tissue diseases (UCTDs) are a heterogeneous group of disorders characterized by symptoms and signs suggestive of systemic autoimmune rheumatic disease (ARD), but which do not fulfill all the established criteria for definite diagnosis of a condition. Although a third of UCTDs can progress to a definite ARD within months or years, most UCTDs can remain stable for years with minimal disease activity. The annual incidence of UCTD in the general population ranges from 14 to 140 per 100 000 people. UCTDs are associated with the persistence of several circulating autoantibodies including antinuclear, antiphospholipid or antithyroid antibodies. Immunological evaluation of subjects with UCTDs suggests a proinflammatory state and dysregulation of the Th1/Th2 balance. Autoantibodies have well-known deleterious effects on placentation and have been associated with an increased risk of prematurity, fetal growth restriction (FGR), preeclampsia, and congenital atrioventricular heart block. Although epidemiological and biological data suggest a potential negative impact on reproductive outcomes, the relationship between UCTD and pregnancy outcomes has not been adequately studied. While awaiting definitive data from large studies, obstetricians should be aware that rheumatic disorders in their early, incomplete, or undifferentiated phases can adversely affect pregnancy outcomes, increasing the likelihood of pregnancy loss, FGR, preeclampsia, and prematurity.

      Abstract: ProblemThe role of extracellular signal-regulated kinase (ERK)1/2-mediated angiogenesis during endometriotic nidation is unknown. We posit that ERK1/2-induced angioblast differentiation and proliferation promotes ectopic endometrial angiogenesis.Methods of studyHuman eutopic and ectopic endometria were immunostained for total- (T-) or phosphorylated- (P-) ERK1/2 or double-immunostained for P-ERK1/2-CD34 and PCNA-CD34. Estradiol (E2), cytokines, normal peritoneal fluid (NPF) or endometriotic peritoneal fluid (EPF) ±PD98059, an ERK1/2 inhibitor, treaded primary human endometrial endothelial cells (HEECs) were evaluated by T-/P-ERK1/2 immunoblotting, MTT viability and tube formation assays.ResultsHEECs exhibited higher endothelial P-ERK1/2 immunoreactivity in ectopic vs eutopic endometria. Double-immunostained ectopic endometria displayed abundant CD34-positive angioblasts exhibiting strong P-ERK1/2 and PCNA immunoreactivity. EPF and vascular growth factor (VEGF)-A significantly increased HEEC proliferation and P-ERK1/2 levels. PD98059 reduced basal, EPF, and VEGF-induced HEEC proliferation and promoted vascular stabilization following tube formation.ConclusionEnhanced ERK1/2 activity in angioblasts by such peritoneal factors as VEGF, E2 induces proliferation to trigger ectopic endometrial angiogenesis.Increased ERK1/2 phosphorylation (P-ERK1/2) is involved in endothelial progenitor cell (angioblast) differentiation and proliferation in endometriosis. Several individual cells (asterisks) and cell clusters of vascular like structures (presumptive vessels; arrows) display the strongest P-ERK1/2 immunoreactivity in the ectopic endometrium, whereas endothelial cells in distal to ectopic tissue (arrowheads) exhibit weak to moderate P-ERK1/2 immunoreactivity (A, B). CD34, an angioblast marker and P-ERK1/2 double immunostaining is seen in ectopic endometrial specimens (C-E) with stronger P-ERK1/2 (brown) immunoreactivity in CD34 immunoreactive (red) endothelial progenitor cells (arrows; C or D) vs. mature vascular endothelial cells (arrowheads in C or E). Representative photomicrographs of CD34 and PCNA double immunostained ectopic endometrial specimens display stronger co-expression of CD34 (red) and PCNA (brown) in endothelial progenitor cells (arrows; F) than in mature vascular endothelial cells (arrowheads; G), indicating proliferative nature of this CD34 immunoreactive angioblasts.
