Project description:The female’s reproductive tract is exposed directly to the male’s ejaculate, making it a hotspot for mating-induced responses shortly after mating. In Drosophila melanogaster, changes in the reproductive tract are essential to optimize fertilization. To detect the earliest gene regulatory events that underlie these changes, we measured transcript abundances using RNA-seq and microRNA-seq of reproductive tracts of unmated females and females collected within 10-15 minutes after the end of mating, either to a wildtype male or to a male with defective BMP signaling in secondary cells of the accessory gland, which influences the composition of the male’s ejaculate. We observed transcript abundance changes for genes with roles in tissue morphogenesis, wound healing, the immune response and metabolism. Strikingly, predicted targets of microRNAs that respond to mating are enriched for overlapping functions, suggesting that mating-induced changes are in part regulated by microRNAs. Most of the differentially expressed RNAs are upregulated in response to mating, while most of the differentially expressed microRNAs are downregulated. This pattern suggests a response of activation and de-repression of gene programs that switch the reproductive tract to a “mated” state, rather than a repression of virgin-specific programs. Male genotype did not influence transcript levels, indicating that the earliest transcriptomic responses in the reproductive tract are not dependent on ejaculate components that require BMP signaling in secondary cells. Our results shed light on the molecular changes that accompany very early responses to mating and present candidate genes and microRNAs that can be further examined for their participation in alterations of the reproductive tract microenvironment in response to signals from the male.

Project description:In order to better understand the female reproductive tract (FRT) we conducted a systematic, comprehensive investigation of the FRT in a tssue-specific manner at three time points relative to mating. By characterizing the transcriptional relationships among discrete FRT tissues across time we advance the understanding of the molecular genetics of FRT functions.

Project description:The male reproductive tract tissue samples were obtained from six 38-wk-old turkeys. The gene expression pattern in turkey testis, epididymis and ductus deferens were determined by high-throughput transcriptome sequencing. The obtained sequence reads were mapped to the turkey genome, and relative expression values were calculated for the analysis of differential expressed genes. Bioinformatics analysis revealed several candidate genes potentially involved in spermatogenesis, spermiogenesis and flagella formation in testis and post-testicular sperm maturation in epididymis and ductus deferens. The achievement of spermatozoa motility during post-testicular maturation were found to be linked with development of flagellum actin filaments and biochemical processes including Ca2+ influx and protein phosphorylation/dephosphorylation. Finally, genes involved in reproductive system development and morphogenesis were identified.

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:The microbiome encompasses the array of microorganisms inhabiting various niches in the body and is necessary for numerous physiological processes, including normal metabolism and a functioning immune system. Not only does the absence of a microbiome in mice impact the exposed animals but also inherited phenotypes in successive generations of progeny, suggesting that the absence of a microbiome impacts the germline and gametes. Indeed, recent research has identified a role of the gut microbiome in contributing to male fertility, in both healthy and disease states. While this link is beginning to be established, the impact of the microbiome on the male reproductive tract remains understudied. Here, we utilized a germ-free mouse model to examine the influence of the absence of microbes on the male reproductive tract. In contrast to mice with an established microbiome, germ-free mice display decreased testicular weight and the prevalence of an epididymitis-like inflammation phenotype. These histopathological changes are accompanied by transcriptomic dysregulation in the reproductive tract of germ-free mice, particularly in the cauda epididymis. Moreover, such transcriptomic changes are transmitted to the next generation with high correlation of gene expression in the cauda epididymis between germ-free mice and their conventionalized (microbiome-restored) male offspring, when compared to control mice. Ultimately, our findings identify the reproductive sequalae of males without a functional microbiome and additionally in their conventionalized offspring, suggesting that the paternal microbiota is an underappreciated contributor to male reproductive function.

Project description:Chlamydia trachomatis urogenital serovars are intracellular bacteria that parasitize human reproductive tract epithelium. As the principal cell type supporting bacterial replication, epithelial cells are central to Chlamydia immunobiology initially as sentries and innate defenders, and subsequently as collaborators in adaptive immunity-mediated bacterial clearance. In asymptomatic individuals who do not seek medical care a decisive struggle between C. trachomatis and host defenses occurs at the epithelial interface. For this study we modeled the immunobiology of epithelial cells and macrophages lining healthy genital mucosa and inflamed/infected mucosa during the transition from innate to adaptive immunity. Upper reproductive tract epithelial cell line responses were compared to bone marrow-derived macrophages utilizing gene expression microarray technology. Those comparisons showed minor differences in the intrinsic innate defenses of macrophages and epithelial cells. Major lineage-specific differences in immunobiology relate to epithelial collaboration with adaptive immunity including an epithelial requirement for inflammatory cytokines to express MHC class II molecules, and a paucity and imbalance between costimulatory and coinhibitory ligands on epithelial cells that potentially limits sterilizing immunity (replication termination) to Chlamydia-specific T cells activated with limited or unconventional second signals. 2 mouse reproductive tract epithelial cell lines compared to bone marrow macrophages untreated vs. treated with inflammatory supernatant (4 replicates each).
