PROBLEM: The immunophenotype of B cells at the maternal-fetal interface (decidua) in labor at term and preterm labor is poorly understood. METHOD OF STUDY: Decidual tissues were obtained from women with preterm or term labor and from non-labor gestational age-matched controls. Immunophenotyping of decidual B cells was performed using multi-color flow cytometry. RESULTS: 1) In the absence of acute or chronic chorioamnionitis, total B cells were more abundant in the decidua parietalis of women who delivered preterm than those who delivered at term, regardless of the presence of labor; 2) decidual transitional and naïve B cells were the most abundant B-cell subsets; 3) decidual B1 B cells were increased in women with labor at term or preterm labor and chronic chorioamnionitis compared to those without this placental lesion; 4) decidual transitional B cells were reduced in women with preterm labor compared to those without labor; 5) naïve, class-switched, and non-class-switched B cells in the decidual tissues underwent mild alterations with the process of preterm labor and/or placental inflammation; 6) decidual plasmablasts seemed to increase in women with labor at term or preterm labor with chronic chorioamnionitis; and 7) decidual B cells expressed high levels of interleukin (IL)-12, IL-6 and/or IL-35...

PROBLEM: Among mechanisms triggering onset of parturition, it has been recently postulated that Toll-Like Receptor (TLR)9 engagement by cell-free DNA (cfDNA) triggers inflammation, myometrial contractions and labor in absence of infection. The current study evaluated whether direct (myometrial) or indirect (decidual) TLR9 engagement enhances human myometrial contractility. METHOD OF STUDY: TLR9 expression and cellular localization were surveyed by immunohistochemistry of placenta, fetal membranes, and myometrium in term (gestational age [GA]:>37 weeks) labor (TL, n=7) or term non-labor (TNL, n=7) tissues...

PROBLEM: Maternal immune system tolerance to the semiallogeneic fetus is critical for a successful pregnancy. Studies have shown that myeloid-derived suppressor cells (MDSCs) play an important role in maintaining feto-maternal tolerance. However, the mechanisms remain poorly understood. METHODS: Flow cytometry was used to evaluate the percentage of MDSCs in an allogeneic-normal-pregnant mouse model during different periods of gestation. We further assessed the percentage of MDSCs and their subtypes (granulocytic MDSCs [GR-MDSCs] and monocytic MDSCs [MO-MDSCs]) in a spontaneous abortion mouse model...

Many approaches have been used to achieve successful pregnancies in patients with infertility, though existing treatments remain unsatisfactory in patients with infertility caused by abnormal maternal-fetal immunity. However, our understanding of the immunological aspects of infertility has steadily progressed, aided by recent research into organ transplantation and cancer. The results of these recent analyses have led to the development and evaluation of several candidate immunological treatments, but the use of immunological treatments remains a novel approach...

Tubal ectopic pregnancy (TEP) refers to implantation of conceptus in the fallopian tube. It makes up over 98% of ectopic pregnancy (EP), which is the leading cause of maternal morbidity and mortality in the first trimester of pregnancy. Immune cells at the maternal-fetal interface play important roles in the process of embryo implantation, stroma decidualization, and early placental development. Alterations in the composition, phenotype, and activity of the immune cells in the fallopian tubes contribute towards the onset of TEP...
