Project description:Metagenome of the female upper reproductive tract

Project description:The female reproductive tract is one of the major mucosal invasion site of HIV-1. This site has been neglected in previous HIV-1 vaccine studies. Immune responses in the female reproductive tract after systemic vaccination remain to be characterized. Using a modified vaccinia virus Ankara (MVA) as a vaccine model, we characterized specific immune responses in all compartments of the female reproductive tract (FRT) of non-human primates after systemic vaccination. Memory T cells were preferentially found in the lower tract (vagina and cervix), whereas antigen-presenting cells and innate lymphoid cells were mainly located in the upper tract (uterus and fallopian tubes). This compartmentalisation of immune cells in the FRT was supported by transcriptomic analyses and correlation network. Polyfunctional MVA-specific CD8+ T cells were detected in the blood, lymph nodes, vagina, cervix, uterus and fallopian tubes. Anti-MVA IgG and IgA were detected in cervicovaginal fluid after a second vaccine dose. Systemic vaccination with an MVA vector thus elicits cellular and antibody responses in the female reproductive tract.

Project description:Cervical-vaginal fluid (CVF) covers the lower part of the female reproductive system and functions in the homeostasis and immunity of the surrounding tissues. The proteome of this proximal fluid has mainly been studied in pregnant women, whereas the CVF proteome of non-pregnant women has not been analyzed in great detail. The CVF peptidome has not been reported to date. In the current study, we separated pooled CVF samples from healthy non-pregnant women into proteomic and peptidomic fractions, followed by mass spectrometry analysis. In total, we identified 1,087 unique proteins in CVF, of which 801 proteins were not previously identified. The presence of the tissue specific proteins oviductal glycoprotein-1 (OVGP-1) and tubulin polymerization-promoting protein family member 3 (TPPP3) in CVF strongly suggests that the tissues of the upper female reproductive tract contribute to the protein composition of CVF. The tremendous catalytic potential of CVF was highlighted by the identification of 85 proteases. The majority of identified proteases belong to the serine protease catalytic type. Over 1,000 endogenous peptides were detected in the CVF peptidome, and 39 peptides are predicted to have antimicrobial activity. The detailed proteomic and peptidomic analysis of CVF will further aid in the delineation of physiological and pathobiological pathways related to reproduction, immunity and host defense, and assist in developing new biomarkers for malignant and other diseases of the female reproductive tract.

Project description:Male-derived accessory gland proteins (Acps) that are transferred to females during mating have profound effects on female reproductive physiology including increased ovulation, mating inhibition, and effects on sperm utilization and storage. The extreme rates of evolution seen in Acps may be driven by sperm competition and sexual conflict, processes which may ultimately drive complex interactions between female- and male-derived molecules and sperm. However, little is known of how gene expression in female reproductive tissues changes in response to the presence of male molecules and sperm. To characterize this response, we conducted parallel genomic and proteomic analyses of gene expression in the reproductive tract of 3-day-old unmated and mated female Drosophila melanogaster. Using DNA microarrays, we identified 539 transcripts that are differentially expressed in unmated vs. mated females and revealed a striking peak in differential expression at 6 hrs postmating and a marked shift from primarily down-regulated to primarily up-regulated transcripts within 3 hrs after mating. Combining two-dimensional gel electrophoresis and liquid chromatography mass spectrometry analyses, we identified 84 differentially expressed proteins at 3 hrs postmating, including proteins which appeared to undergo post-translational modification. Together, our observations define transcriptional and translational response to mating within the female reproductive tract and suggest a bimodal model of postmating gene expression initially correlated with mating and the final stages of female reproductive tract maturation and later with the declining presence of male reproductive molecules and with sperm maintenance and utilization. Experiment Overall Design: Three-day-old mated and unmated females were dissected to remove the lower reproductive tract (upper uterus, sperm-storage organs, and accessory glands). Mated females were dissected either immediately following mating (0 hr) or at 3, 6, or 24 hrs following the termination of mating. Tracts of 12-40 females of like category were pooled and total RNA extracted via a TRIzol-based protocol. Processing and labeling of transcript was performed by the Molecular Biology Core Facility at the Medical College of Georgia. Arrays from mated females at the different timepoints were compared to unmated females.

Project description:Reproductive traits that influence female remating and competitive fertilization rapidly evolve in response to sexual selection and sexual conflict. One such trait, observed across diverse animal taxa, is the formation of a structural plug inside the female reproductive tract, either during or shortly after mating. In Drosophila melanogaster, male seminal fluid forms a mating plug inside the female bursa, which has been demonstrated to influence sperm entry into storage and latency of female remating. Processing of the plug, including its eventual ejection from the female's reproductive tract, influences the competitive fertilization success of her mates and is mediated by female × male genotypic interactions. However, female contributions to plug formation and processing have received limited attention. Using developmental mutants that lack glandular female reproductive tract tissues, we reveal that these glandular tissues are essential for the mating plug to be ejected. We further use proteomics to demonstrate that female glandular proteins, and especially proteolytic enzymes, contribute to mating plug composition and that the absence of glands has a widespread impact of plug formation and composition. Together, these phenotypic and molecular data resolve molecular mechanisms of important postmating, intersexual interactions and cryptic female choice.
