Oral sex is associated with reduced incidence of recurrent miscarriage.

J Reprod Immunol 2019 Mar 27;133:1-6. Epub 2019 Mar 27.

Department of Obstetrics, Leiden University Medical Centre, Leiden, the Netherlands; Department of Obstetrics, Wilhelmina Children Hospital Birth Centre, Division Woman and Baby, University Medical Centre Utrecht, Utrecht, the Netherlands.

A possible way of immunomodulation of the maternal immune system before pregnancy would be exposure to paternal antigens via seminal fluid to oral mucosa. We hypothesized that women with recurrent miscarriage have had less oral sex compared to women with uneventful pregnancy. In a matched case control study, 97 women with at least three unexplained consecutive miscarriages prior to the 20 week of gestation with the same partner were included. Read More

Authors:
Gerard Chaouat

J Reprod Immunol 2019 Apr 20;132:49-53. Epub 2019 Mar 20.

U976 INSERM Hopital Saint Louis Pavillon Bazin, 75010 Paris France. Electronic address:

In this summary of my presentation in the last Reunion workshop I discuss a few assertions on preeclampsia, then turn on a (not fully testable) model where an embryonic defect in expression of embryo/ placental regulatory proteins results in complement activation, itself responsible for a down regulation of the T regs activity, resulting in a very early lack of complete down regulation of the preimplantation decidual inflammation, causing in the post implantation stage a low grade but chronic inflammatory state.

Estradiol impairs epithelial CXCL1 gradient in the cervix to delay neutrophil transepithelial migration during insemination.

J Reprod Immunol 2019 Apr 18;132:9-15. Epub 2019 Feb 18.

Laboratorio de InmunoFisiología, Grupo Fisiopatología de la mujer, del embarazo, parto y puerperio. Instituto de Investigación Sanitaria Gregorio Marañón, Madrid, Spain. Electronic address:

Female reproductive mucosa must allow allogenic sperm survival whereas at the same time, avoid pathogen infection. To preserve sperm from neutrophil attack, neutrophils disappear from the vagina during the ovulatory phase (high estradiol); although the mechanisms that regulate neutrophil influx to the vagina during insemination remain controversial. We investigated the sex hormone regulation of the neutrophil migration through the cervix during insemination and revealed that ovulatory estradiol dose fades the CXCL1 epithelial expression in the ectocervix and fornix; hence, retarding neutrophil migration and retaining them in the epithelium.

Department of Obstetrics and Gynecology, Rambam Medical Center, Haifa, Israel; Rappaport faculty of Medicine, Techinon-Isarel Institute of Technology, Israel. Electronic address:

Introduction: immature-myeloid cells (IMCs) are proangiogenic bone marrow (BM)-derived cells that normally differentiate into inflammatory cells such as neutrophils, monocytes and dendritic cells (DCs). We characterized placental IMCs comparing their gene expression and subpopulations to tumor IMCs, and tested our hypothesis that progesterone that inhibits preterm labor, may affect their abundance and differentiation.

Methods: differences between IMC-subpopulations in subcutaneous tumors versus placentas in C57BL/6 or ICR (CD-1) mice were analyzed by flow cytometry and gene expression was detected by microarrays. Read More

Robinson Research Institute, School of Medicine, The University of Adelaide, Adelaide, SA, 5005, Australia. Electronic address:

The detrimental consequences of obesity on female fertility are well known, but the functional changes that occur in the ovary in response to elevated BMI are not clear. Obesity induces multiple components of a systemic inflammatory state that is a key pathway by which it initiates tissue dysfunction in adipose, liver and muscle; however whether obesity induces similar inflammatory changes in the ovary has not been fully investigated. This is important to understand because it is increasingly clear that obesity at conception impacts not only pregnancy rates but also influences pre-implantation embryo development. Read More

The combination of maternal KIR-B and fetal HLA-C2 is associated with decidua basalis acute atherosis in pregnancies with preeclampsia.

J Reprod Immunol 2018 Sep 25;129:23-29. Epub 2018 Jul 25.

Institute for Clinical Medicine, Faculty of Medicine, University of Oslo, Norway; Division of Obstetrics and Gyneacology, Oslo University Hospital, Norway.

Acute atherosis is an arterial lesion most often occurring in pregnancies complicated by preeclampsia, a hypertensive pregnancy disorder. Acute atherosis predominates in the maternal spiral arteries in the decidua basalis layer of the pregnant uterus. This layer forms the fetal-maternal immunological interface, where fetal extravillous trophoblasts interact with maternal immune cells to promote decidual spiral artery remodeling and maternal immune tolerance towards the fetus.

Inflammation induced preterm labor and birth.

J Reprod Immunol 2018 Sep 30;129:53-58. Epub 2018 Jun 30.

Clinical Immunology Laboratory, Department of Microbiology and Immunology, Chicago Medical School, Rosalind Franklin University of Medicine and Science, North Chicago, IL 60064, United States.

Preterm birth which occurs before 37 weeks gestation is one of the most common obstetrical complication in humans. After many studies, it appears that "not one answer fits all" regarding the risk factors, causes and the treatments for this syndrome. However, it is becoming more evident that one of the major risk factors is inflammation and/or infection in the fetoplacental unit. Read More

Preeclampsia serum induces human glomerular vascular endothelial cell hyperpermeability via the HMGB1-Caveolin-1 pathway.

J Reprod Immunol 2018 Sep 6;129:1-8. Epub 2018 Jul 6.

Obstetric Intensive Care Center, The Institute of Obstetrics and Gynecology, Department of Obstetrics and Gynecology, Affiliated Sixth People's Hospital, Shanghai Jiao Tong University, Shanghai, China. Electronic address:

To explore new ideas about the pathogeny of preeclampsia (PE) proteinuria, this study focused on whether severe PE serum (PES) could induce high-molecular-weight protein (HMWP) hyperpermeability in glomerular endothelial cells (GEC) via the HMGB1-Caveolin-1 (CAV-1) pathway. Normal pregnancy serum (NPS) and severe PES were used to treat primary human GEC monolayer for 24 h. The CAV-1 inhibitor methyl-beta-cyclodextrin (MBCD), the HMGB1 inhibitor glycyrrhizicacid (GA), recombinant HMGB1 (rHMGB1) were also used to treat GEC monolayer that were stimulated by NPS or severe PES.

HLA-DR is aberrantly expressed at feto-maternal interface in pre-eclampsia.

J Reprod Immunol 2018 Sep 19;129:48-52. Epub 2018 Jun 19.

Nuffield Department of Obstetrics and Gynaecology, University of Oxford, Oxford, OX3 9DU, UK.

In normal pregnancy, villous cytotrophoblast and syncytiotrophoblast do not express HLA Class I and Class II molecules, while invasive extravillous trophoblast only express class I HLA-C and the atypical class Ib antigens, HLA-G, -E and -F. Inadequate maternal tolerance of invasive trophoblast has been proposed as a possible immunologic trigger of poor trophoblast invasion and subsequent occurrence of pre-eclampsia. This study aimed to investigate possible aberrant expression of class II HLA-DR on placentae and syncytiotrophoblast-derived extracellular vesicles (STEVs), obtained by dual placental perfusion, from pre-eclampsia (n = 23) and normal pregnant (n = 14) women.

Soluble CD200 in secretory phase endometriosis endometrial venules may explain endometriosis pathophysiology and provide a novel treatment target.

J Reprod Immunol 2018 Sep 21;129:59-67. Epub 2018 May 21.

Department of Pathology and Molecular Medicine, McMaster University, Hamilton, Ontario, Canada.

Retrograde menstruation is common and in about 10% of women, endometrial tissues implant at ectopic sites and grow as endometriosis (EM) deposits. To date, there has been no marker to identify which patients have an endometrium that will generate deposits. Both endometrial regulatory T cells (Tregs) and increased stromal cell indoleamine 2,3-dioxygenase (IDO) have been implicated, and may suppress rejection by peritoneal NK cells, neutrophils, and cytotoxic macrophages.

Innate immune responses to toll-like receptor stimulation are altered during the course of pregnancy.

J Reprod Immunol 2018 Aug 24;128:30-37. Epub 2018 May 24.

Heinrich Pette Institute, Leibniz Institute for Experimental Virology, Martinistrasse 52, Hamburg, 20251, Germany. Electronic address:

During pregnancy the maternal immune system has to develop tolerance towards the developing fetus. These changes in maternal immunity can result in increased severity of certain infections, but also in amelioration of autoimmune diseases. Pregnancy-related hormones have been suggested to play a central role in the adaptation of the maternal immune system, but their specific effects on innate immune function is not well understood.

Department of Clinical Science, University of Bergen, Bergen, Norway; Department of Obstetrics and Gynecology, Haukeland University Hospital, Bergen, Norway.

Immunological mechanisms underlying the development of preeclampsia are well known, but no association to allergy has yet been demonstrated. The aim of this study was to assess the correlation between maternal pre-gestational allergy, and early-onset and late-onset preeclampsia, respectively. It was a retrospective cohort study including all women giving birth in the Norwegian cities of Stavanger (1996-2014) and Bergen (2009-2014). Read More

Poly (I:C) and LPS induce distinct immune responses by ovarian stromal fibroblasts.

J Reprod Immunol 2018 Jun 9;127:36-42. Epub 2018 May 9.

Department of Microbiology and Immunology, Geisel School of Medicine at Dartmouth, Lebanon, NH, 03756, USA.

Despite its anatomical location, the ovary is a site of pathogen exposure in the human female reproductive tract (FRT). However, the role of ovarian stromal fibroblasts in immune protection is unclear. We generated a population of ovarian stromal fibroblasts derived from normal human ovaries that expressed the pattern recognition receptors TLR3, TLR4, RIG-I, & MDA5. Read More

Impact of prednisone in patients with repeated embryo implantation failures: Beneficial or deleterious?

J Reprod Immunol 2018 Jun 26;127:11-15. Epub 2018 Mar 26.

Institut National de Santé et de Recherche Médicale, INSERM UMR-976, Saint-Louis Hospital, Research Center, 1 Avenue Claude Vellefaux, 75010, Paris, France.

Introduction: Corticotherapy is the leading medication worldwide for patients with history of repeated implantation failures (RIF) after IVF/ICSI. Nevertheless, we still do not know its local mechanism of action, hence its precise indication. Our objective is to document the impact of prednisone on the endometrial expression of immune biomarkers (CD56 cells count, IL-18/TWEAK, IL-15/Fn-14 mRNA ratio) at the time of uterine receptivity in a RIF population.

The Ronald O. Perelman and Claudia Cohen Center for Reproductive Medicine, Weill Cornell Medicine, New York, NY 10021, United States. Electronic address:

An elevated level of insulin growth factor (IGF-1) in rat uterine fluid has been shown to exert detrimental effects of embryo development possibly leading to an increase in pregnancy loss. Interestingly, the administration of somatostatin to rats undergoing superovulation reduced IGF-1 levels in uterine luminal fluid and thus reversed its deleterious effects on embryo development and increased the number of normal embryos. Therefore, we investigated whether serum levels of IGF-1 correlate with the incidence of pregnancy loss following IVF. Read More
