Genital proteins in women at risk of HIV infection

ABSTRACT: In this study, we used a bead-based affinity proteomics method to examine genital proteins in women living in HIV-serodiscordant relationships. Proteins identified using the affinity set-up were validated by a label free tandem mass spectrometry based method in a parallel cohort with concordant results.

Women at high risk of HIV infection, including sex workers and those with active genital inflammation, have molecular signatures of immune activation and epithelial barrier remodeling in samples of their genital mucosa. These alterations in the local immunological milieu are likely to impact HIV susceptibility. We here analyze host genital protein signatures in HIV uninfected women, with high frequency of condom use, living in HIV-serodiscordant relationships. Cervicovaginal secretions from wome ...[more]

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.

High-throughput miRNA sequencing and identification of biomarkers for forensically relevant biological fluids

Project description:In this study, small RNAs were isolated from individual donations of eight forensically relevant biological fluids (blood, semen, vaginal fluid, menstrual blood, saliva, urine, feces, and perspiration) and subjected to next generation sequencing using the IlluminaÂ® Hi-Seq platform. Sequencing reads were aligned and annotated against miRbase release 21, resulting in a list of miRNAs and their relative expression levels for each sample analyzed. Body fluids with high bacterial loads (vaginal fluid, saliva, and feces) yielded relatively low annotated miRNA counts, likely due to oversaturation of small RNAs from the endogenous bacteria. Both body-fluid specific and potential normalization miRNAs were identified for further analysis as potential body fluid identification tools for each body fluid. 32 samples - 3-5 replicates of each human biological fluid: venous blood, urine, semen (normal and vasectomized), vaginal secretions, menstrual secretions, perspiration, feces, saliva

The Genetic Basis of Rapidly Evolving Male Genital Morphology in Drosophila

Project description:Deep sequencing of total RNA extracted from the genital discs of males for each of the following strains : Drosophila sechellia, Drosophila mauritiana, hybrid introgression line 3Q1(A) and hybrid introgression line Q1(A) Analysis of poly(A)+ RNA for three independent biological replicates of sequencing libraries for each of the following strains: D. sechellia w, D. mauritiana P-insertion Q1, hybrid introgression line 3Q1(A), and hybrid introgression line Q1(A). Male genital discs were obtained as described above, and total RNA was extracted using RNAqueousM-CM-^BM-BM-.-Micro Kit (Ambion). Poly(A)+ transcripts were isolated subsequently using MicroPoly(A)PuristM-CM-"M-BM-^DM-BM-" Kit (Ambion). To facilitate normalization of reads across our samples, at this stage of library construction we spiked-in small amounts of exogenous RNA from ArrayControlM-CM-"M-BM-^DM-BM-" Kit (Ambion) into each sample of poly(A)+ RNA. Paired-end sequencing was carried out by loading the samples onto four lanes (three samples per lane) of a flow cell and run on an Illumina Genome Analyzer IIx sequencer using 72 cycles per end of each paired-end read. Biological replicates of each genotype were loaded onto separate lanes.

The secretome of the rumen fluke, Calicophoron daubneyi

Project description:Helminth parasites secrete molecules in soluble form (i.e the secretome) or packaged into extracellular vesicles (EVs) as a means of exporting effector molecules into the host microenvironment. Once released, the parasite-derived molecules can trigger a range of biological effects including modulation of host immunity. While the secretome and molecular cargo of EVs have been characterised in many parasites, little is known about the molecules released by the rumen fluke, Calicophoron daubneyi – an emerging infection of livestock in Western Europe. Here we used a mass spectrometry-based proteomics approach to characterise the secretome of the infective newly-excysted juvenile (NEJ) stage and adult flukes. We also profile the proteome of two sub-populations of EVs (termed 15K and 120K EVs) released by the adult flukes.

Aging modifies endometrial dendritic cell function and unconventional double negative T cells in the human genital mucosa.

Project description:Immune function in the genital mucosa balances reproduction with protection against pathogens. As women age, genital infections, and gynecological cancer risk increase, however, the mechanisms that regulate cell-mediated immune protection in the female genital tract and how they change with aging remain poorly understood. Unconventional double negative (DN) T cells (TCRαβ + CD4-CD8-) are thought to play important roles in reproduction in mice but have yet to be characterized in the human female genital tract. Using genital tissues from women (27–77 years old), here we investigated the impact of aging on the induction, distribution, and function of DN T cells throughout the female genital tract.

Genital fibroblasts of normal males and 46,XY females with androgen insensitivity syndrome

Project description:This SuperSeries is composed of the following subset Series: GSE3871: Effects of androgen treatment on genital fibroblasts GSE3872: Baseline gene transcription in genital fibroblasts Abstract: BACKGROUND: Androgen insensitivity syndrome (AIS) comprises a range of phenotypes from male infertility to complete feminization. Most individuals with AIS carry germline mutations of the androgen receptor (AR) that interfere with or ablate its function. As genital fibroblasts retain expression of the AR in vitro, we used genital skin fibroblasts from normal males and 46,XY females with complete AIS due to known AR mutations to gain insights into the role of the AR in human genital differentiation. RESULTS: Using DNA microarrays representing 32,968 different genes, we identified 404 transcripts with significant differences in transcription levels between genital skin fibroblasts cultured from normal and AIS-affected individuals. Gene-cluster analyses uncovered coordinated expression of genes involved in key processes of morphogenesis. On the basis of animal studies and human genetic syndromes, several of these genes are known to have specific roles in genital differentiation. Remarkably, genital fibroblasts from both normal and AIS-affected individuals showed no transcriptional response to dihydrotestosterone treatment despite expression of the AR. CONCLUSIONS: The results suggest that in addition to differences in the anatomic origin of the cells, androgen signaling during prenatal development contributes to setting long-lasting, androgen-independent transcriptional programs in genital fibroblasts. Our findings have broad implications in understanding the establishment and the stability of sexual dimorphism in human genital development. Refer to individual Series
