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: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).

Project description:The vertebrate nuclear hormone receptor steroidogenic factor 1 (SF1; NR5A1) controls reproductive development and regulates the transcription of steroid-modifying cytochrome P450 genes. We find that the SF1-related Drosophila nuclear hormone receptor HR39 is also essential for sexual development. In Hr39 mutant females, the sperm-storing spermathecae and glandular parovaria are absent or defective, causing sterility. Our results indicate that spermathecae and parovaria secrete reproductive tract proteins required for sperm maturation and function, like the mammalian epididymis and female reproductive tract. Hr39 controls the expression of specific cytochrome P450 genes and is required in females both to activate spermathecal secretion and repress male-specific courtship genes such as takeout. Thus, a pathway that, in vertebrates, controls sex-specific steroid hormone production, also mediates reproductive functions in an invertebrate. Our findings suggest that Drosophila can be used to model more aspects of mammalian reproductive biology than previously believed. Keywords: mutant/wild-type comparison and tissue comparison
