Seminal plasma promotes decidualization of endometrial stromal fibroblasts from women with and without inflammatory disorders in a manner dependent on IL11 signaling

ABSTRACT: SP promotes decidualization of eSF from women with and without inflammatory disorders (polycystic ovarian syndrome (PCOS), endometriosis) in a manner that is not mediated through semen amyloids and that is associated with a potent transcriptional response including induction of IL11, a cytokine important for SP-induced decidualization.

Seminal plasma induces global transcriptomic changes associated with cell migration, proliferation and viability in endometrial epithelial cells and stromal fibroblasts.

Project description:Exposure of eEC and eSF to SP in vitro increases expression of genes and secreted proteins associated with cellular migration, proliferation, viability and inhibition of cell death. This is a cross sectional study involving control samples versus treatment. SP (pooled from twenty donors) was first tested for dose- and time-dependent cytotoxic effects on eEC and eSF (n = 4). As exposure of eEC or eSF to 1% SP for 6 h proved to be non-toxic, a second set of eEC/eSF samples (n = 4) was treated under these conditions for transcriptome, protein and functional analysis. With a third set of samples (n = 3), we further compared the transcriptional response of the cells to SP versus fresh semen.

IL11 is elevated in systemic sclerosis and IL11-dependent ERK signaling is needed for the profibrotic activity of TGFβ in dermal fibroblasts

Project description:Objectives: Interleukin 11 (IL11) is highly upregulated in skin and lung fibroblasts from patients with systemic sclerosis (SSc). Here we tested whether IL11 is mechanistically linked with human dermal fibroblast (HDF) activation. Methods: We measured serum IL11 levels in healthy volunteers and patients with early diffuse SSc and manipulated IL11 signalling in HDFs using gain- and loss-of-function approaches. Results: In patients with SSc, serum IL11 levels are elevated as compared to healthy controls. Transforming growth factor beta (TGFβ) isoforms 1, 2 or 3 induced IL11 secretion from HDFs, which highly express IL11RA and the gp130 co-receptor, suggestive of an autocrine loop of IL11 activity in HDFs. IL11 consistently and robustly stimulated ERK activation in HDFs and resulted in HDF-to-myofibroblast transformation. IL11 induced STAT phosphorylation to a lesser extent than ERK and only at high IL11 concentrations. IL11-stimulated ERK activation and fibrosis phenotypes were absent in skin fibroblasts from patients with homozygous loss-of-function mutation in IL11RA. Inhibition of IL11 signaling using either a neutralizing antibody against IL11 or siRNA against IL11RA reduced TGFβ-induced HDF proliferation, matrix production and cell migration, which was phenocopied by pharmacologic inhibition of ERK activity. Conclusions: These data reveal an important contribution of IL11-related ERK activity for TGFβ-stimulated fibrosis phenotypes in HDFs and suggest IL11 as a potential therapeutic target in SSc.

Endometrial extracellular vesicle decidualization

Project description:Proper decidualization is vital in preparation for a potential embryo receptivity, placentation, menstrual health and subsequent endometrial regeneration. Given the importance of extracellular vesicles (EVs) in intercellular communication, and recently in embryo implantation and indicators of menstrual cycle and fertility, we investigated their role during decidualization. Overall, this study provides an insight into distinct variation in sEV composition depending upon the level of decidualization of endometrial stromal cells, with the signaling potential to coordinate endometrial health ranging from embryo implantation, facilitating placentation and subsequent endometrial regeneration.

Cardiomyocyte-Restricted Expression of IL11 Causes Cardiac Fibrosis, Inflammation, and Dysfunction

Project description:Background: Cardiac fibrosis is a common pathological process in heart disease and represents a therapeutic target. TGFβ is the canonical driver of cardiac fibrosis and was recently shown to be dependent on IL11 for its profibrotic effects in fibroblasts. In the opposite direction, recombinant human IL11 has been reported as anti-fibrotic and also anti-inflammatory in the mouse heart. Objectives: In this study, we determined the effects of IL11 expression in cardiomyocytes on cardiac pathobiology and function. Methods: We used the Cre-loxP system to generate a tamoxifen-inducible mouse with cardiomyocyte-restricted murine Il11 expression. Using protein assays, bulk RNA-sequencing and in vivo imaging we analysed the effects of IL11 on myocardial fibrosis, inflammation and cardiac function and challenge previous reports suggesting cardioprotective potential of IL11. Results: TGFβ stimulation of cardiomyocytes caused Il11 upregulation. As compared to wild-type controls, Il11 expressing hearts demonstrated severe cardiac fibrosis and inflammation that was associated with the upregulation of cytokines, chemokines, complement factors and increased inflammatory cells. IL11 expression also activated a programme of endothelial-to-mesenchymal transition and resulted in left ventricular dysfunction. Conclusion: Our data define species-matched IL11 as strongly profibrotic and proinflammatory when secreted from cardiomyocytes and further establish IL11 as a disease factor.

Seminal Plasma-Derived Extracellular-Vesicle Fractions from HIV-Infected Men Exhibit Unique MicroRNA Signatures and Induce a Proinflammatory Response in Cells Isolated from the Female Reproductive Tract

Project description:The continuing spread of HIV/AIDS is predominantly fueled by sexual exposure to HIV-contaminated semen. Seminal plasma (SP), the liquid portion of semen, harbors a variety of factors that may favor HIV transmission by facilitating viral entry into host cells, eliciting the production of pro-inflammatory cytokines, and enhancing the translocation of HIV across the genital epithelium. One important and abundant class of factors in SP is extracellular vesicles (EVs), which in general are important intercellular signal transducers. Although numerous studies have characterized blood plasma-derived EVs from both uninfected and HIV-infected individuals, little is known about the properties of EVs from semen of HIV-infected individuals. We report here that fractionated SP enriched for EVs from HIV-infected men induce potent transcriptional responses in epithelial and stromal cells that interface with luminal contents of the female reproductive tract. Compared to semen EV fractions from uninfected individuals, those from acutely-infected individuals induced a more pro-inflammatory signature. This was not associated with any observable differences in the surface phenotypes of the vesicles. However, miRNA expression profiling analysis revealed that EV fractions from infected individuals exhibit a broader and more diverse profile. Taken together, our data suggest that SP EVs from HIV-infected individuals exhibit unique miRNA signatures and exert potent pro-inflammatory transcriptional changes in cells of the female reproductive tract, which may facilitate HIV transmission.

Endometrial gland impacts on stromal cell decidualization

Project description:Uterine glands and, by inference, their secretions impact uterine receptivity, blastocyst implantation, stromal cell decidualization, and placental development. Changes in gland function across the menstrual cycle are impacted by steroid hormones, estrogen and progesterone, as well as stroma-derived factors. Using an endometrial epithelial organoid (EEO) system, transcriptome and proteome analyses identified distinct responses of the EEO to steroid hormones and prostaglandin E2 (PGE2). Notably, steroid hormones and PGE2 modulated the basolateral secretion of EEO proteins, where cystatin C (CST3) was significantly increased by progesterone and PGE2. CST3 treatment of decidualizing stromal cells significantly decreased the decidualization markers PRL and IGFBP1. The attenuation of stromal cell decidualization via CST3 suggests a role for uterine gland-derived proteins in controlling the extent of decidualization. These findings provide evidence that uterine gland-derived factors directly impact stromal cell decidualization, which has strong implications for better understanding pregnancy establishment and female fertility in humans.

Seminal plasma exposures strengthen vaccine responses in the female reproductive tract mucosae

Project description:HIV-1 sexual transmission occurs mainly via mucosal semen exposures. In the female reproductive tract (FRT), seminal plasma (SP) induces physiological modifications, including inflammation. An effective HIV-1 vaccine should elicit mucosal immunity. However, modifications of vaccine responses by the local environment remain to be characterized. Using a modified vaccinia virus Ankara (MVA) as a vaccine model, we characterized the impact of HIV-1+ SP intravaginal exposure on the local immune responses of nonhuman primates. Multiple HIV-1+ SP exposures did not impact the anti-MVA antibody responses. However, SP exposures revealed an anti-MVA responses mediated by CD4+ T cells, which was not observed in the control group. Multi-parameter approaches clearly identified the cervix as the most impacted compartment in the FRT. The frequency and the quality of specific anti-MVA CD8+ T cell responses increased in the FRT exposed to SP. Furthermore SP exposures induced a local cell recruitment of antigen presenting cells, especially CD11c+ cells and CD8+ T cell recruitment in the FRT draining lymph nodes. CD11c+ cell recruitment was associated with upregulation of inflammation-related gene expression after SP exposures in the cervix. We thus highlight the fact that physiological conditions, such as SP exposures, should be taken into consideration to test and to improve vaccine efficacy against HIV-1 and other sexually transmitted infections.

Integrated target discovery screens identify IL11 as novel therapeutic target for fibrosis [mouse]

Project description:Cardiac fibrosis is the final common pathology in heart disease. Here we establish an integrated imaging-genomic discovery platform using primary human heart fibroblasts to identify new drug targets for cardiac fibrosis. Genome wide analyses identify IL11, a secreted cytokine amenable to therapeutic inhibition, as the leading pro-fibrotic candidate. We demonstrate an autocrine loop of IL11 activity that is critical for fibrosis and acts as a nexus of signalling convergence for multiple pro-fibrotic stimuli. IL11 signals in cis and trans via the ERK cascade to activate a programme of fibrosis primarily at the level of protein translation. Injection of IL11 to mice causes fibrosis of the heart, kidney, lung, skin and liver whereas genetic ablation of the IL11 receptor prevented fibrosis across tissues. These data define a new non-canonical fibrogenic pathway and prioritise IL11 as a novel therapeutic target for fibrosis of the heart and other organs
