The Dynamics of the Vaginal Microbiome During Infertility Therapy with In Vitro Fertilization-Embryo Transfer

Project description:Clinical treatment protocols for infertility with in vitro fertilization-embryo transfer (IVF-ET) provide a unique opportunity to assess the human vaginal microbiome in defined hormonal milieu. Herein, we have investigated the association of circulating ovarian-derived estradiol (E2) and progesterone (P4) concentrations to the vaginal microbiome. Thirty IVF-ET patients were enrolled in this study, after informed consent. Blood was drawn at four time points during the IVF-ET procedure. In addition, if a pregnancy resulted, blood was drawn at 4-to-6 weeks of gestation. The serum concentrations of E2 and P4 were measured. Vaginal swabs were obtained in different hormonal milieu. Two independent genome-based technologies (and the second assayed in two different ways) were employed to identify the vaginal microbes. The vaginal microbiome underwent a transition with a decrease in E2 (and/or a decrease in P4). Novel bacteria were found in the vagina of 33% of the women undergoing IVF-ET. Our approach has enabled the discovery of novel, previously unidentified bacterial species in the human vagina in different hormonal milieu. While the relationship of hormone concentration and vaginal microbes was found to be complex, the data support a shift in the microbiome of the human vagina during IVF-ET therapy using standard protocols. The data also set the foundation for further studies examining correlations between IVF-ET outcome and the vaginal microbiome within a larger study population.

Vaginal epithelial gene expression in postmenopausal women suffering from vaginal dryness

Project description:The onset of menopause is accompanied by a dramatic increase in reported symptoms of vaginal dryness, soreness, irritation or itching, pain with intercourse and bleeding after intercourse. Collectively these affect 25-50% of women of post-menopausal age and significantly impact their quality of life. To examine how gene expression differs between these groups, surface vaginal epithelial cells were collected from postmenopausal women suffering from vaginal dryness and appropriate controls not suffering from dryness. Affymetrix GeneChip Human 1.0 ST microarrays were performed on RNA isolated from ten participants.

Vaginal epithelial dysfunction is mediated by the microbiome, metabolome, and mTOR signaling - Participant Group 2

Project description:Bacterial vaginosis (BV) is characterized by depletion of Lactobacillus and overgrowth of anaerobic and facultative bacteria, leading to increased mucosal inflammation, epithelial disruption, and poor reproductive health outcomes. However, the molecular mediators contributing to vaginal epithelial dysfunction are poorly understood. Here we utilized proteomic, transcriptomic and metabolomic analyses to characterize biological features underlying BV in 405 African women and explored functional mechanisms using bacterial co-cultures in vitro. We identified five major vaginal microbiome groups, (L.crispatus(21%), L.iners(18%), any non-specific Lactobacillus species(9%), Gardnerella species .vaginalis(30%), or polymicrobial(22%)). Using multi-‘omics we show that BV associated epithelial disruption and mucosal inflammation are linked to the mammalian target of rapamycin (mTOR) pathway and associate with Gardnerella.vaginalis, Mobiluncus mulieris, and specific metabolites including imidazole propionate. Bacterial co-culture experiments in vitro confirmed that type strain G.vaginalis and, M.mulieris supernatants as well as imidazole propionate, directly affect epithelial barrier function and are accompanied by activation of mTOR pathways. These results establish the microbiome-mTOR axis as a central feature of epithelial dysfunction in BV.
