Project description:We have used 10x singel cell immune profiling methods to analyze gene expression and TCR clonotypes simultaneously of freshly isolated human ectocervix biopsies. Our main goal is to define phenotypes and clonotypes of different subsets of tissue resident CD8 T cells in normal human cervix tissues.

Project description:In mice, seminal fluid elicits an inflammation-like response in the female genital tract that activates immune adaptations to advance the likelihood of conception and pregnancy. Here we examined whether similar changes in leukocyte and cytokine parameters occur in the human cervix in response to the male partner’s seminal fluid. After a period of abstinence in proven-fertile women, duplicate sets of biopsies were taken from the ectocervix in the peri-ovulatory period and again 48 h later, 12 h after unprotected vaginal coitus, vaginal coitus with use of a condom, or no coitus. One pair of first biopsy and second biopsy RNA samples from each treatment group were reverse transcribed into cDNA and hybridized to Affymetrix Human Gene 1.0 ST arrays. A total of 713 probe sets were identified as differentially expressed (fold change >2) between first and second biopsies after unprotected coitus, with 436 genes upregulated and 277 genes downregulated. Ingenuity Pathway Analysis revealed that gene pathways including inflammatory response, immune response, immune cell trafficking, cellular movement and antigen presentation were significantly affected by seminal fluid exposure. Amongst these were genes encoding several chemokines which target granulocytes, monocyte/macrophages, dendritic cells and lymphocytes, proinflammatory cytokines and regulators of cytokine synthesis, prostaglandin pathway gene including PTGS2; COX-2) and several matrix metalloproteinases (MMPs). Of these genes, no change or a substantially smaller change was seen between first and second biopsies obtained after coitus with condom use, or abstinence. An increase in CSF2, IL6, IL8 and IL1A expression was confirmed by qRT-PCR in larger sets of duplicate biopsies (n=6-7 per group). We conclude that seminal fluid introduced at intercourse elicits expression of pro-inflammatory cytokines and chemokines which underpins the accompanying recruitment of macrophages, dendritic cells and memory T cells. The leukocyte and cytokine environment induced in the cervix by seminal fluid appears competent to initiate adaptations in the female immune response that promote fertility. This response is also relevant to transmission of sexually transmitted pathogens, and potentially susceptibility to cervical metaplasia. Women aged 18-40 years, with regular menstrual cycles and a current sexual relationship with a proven fertile regular partner, volunteered for the study. All women had previously undergone tubal ligation and none of the women used steroidal contraceptives or an intrauterine device for a minimum of three months preceding the study. Subjects were screened to exclude bacterial or viral infection. A negative test result was a prerequisite for inclusion in the study. The study was approved by the local ethics committee of Karolinska University Hospital, Stockholm, Sweden. RNA from each of six cervical biopsies was analysed. The six tissues comprised three pairs of cervical biopsies (a ‘first’ and a ‘second’ biopsy); one pair from each of three women assigned to three different treatment protocols. Treatments were (1) no coitus (control); (2) coitus with a condom (condom), or (3) unprotected coitus (coitus). To synchronise the timing of the biopsies, all subjects determined their LH peak in urine samples taken twice daily from approximately day 10 after the onset of menstruation to the time at which an LH increase was detected (LH0-LH+1), using a rapid self-test (Clearplan, Searle Unipath Ltd., Bedford, UK). The first biopsy was recovered during the peri-ovulatory stage of the menstrual cycle (at 0900 h - 1200 h on day LH0 to LH+1), and the second biopsy was recovered 48 h later (at 0900 h - 1200 h on day LH+2 to LH+3). Small needle biopsies (approximately 50-100 mg tissue) were taken from the ectocervix, approximately 1 cm from the transformation zone. Women then abstained from intercourse for 36 hours to enable haemostasis and healing of the biopsy site. Women allocated to groups (1) and (2) had intercourse, without or with condom use respectively, on one occasion approximately 36 hours after the first biopsy and 12 hours prior to the second biopsy. The abstinent woman did not have intercourse between the two biopsies. Before all biopsies, the cervix was washed with 10 ml of saline solution to clear mucous and debris. All cervical washings were collected and examined microscopically for the presence of sperm to confirm compliance.

Project description:Modulation of mucus production by the human endo- and ecto-cervical epithelium by steroid hormones and associated interactions with commensal microbiome play a central role in the physiology and pathophysiology of the female reproductive tract. However, most of our knowledge about these interactions is based on results from animal studies or in vitro models that fail to faithfully mimic the mucosal environment of the human cervix. Here we describe microfluidic organ-on-a-chip (Organ Chip) models of the human cervical mucosa that recreate the cervical epithelial-stromal interface with a functional epithelial barrier and produce abundant mucus that has compositional, biophysical, and hormone-responsive properties similar to the living cervix. Application of continuous fluid flow to chips lined primary human cervical epithelial cells from a commercial source that contained a mixture of primary human ecto- and endo-cervical epithelial cells promoted preferential expression of the ecto-cervical phenotype, whereas use of periodic flow including periods of stasis induced endo-cervical specialization. When the periodic flow Cervix Chips were co-cultured with living Lactobacillus crispatus and Gardnerella vaginalis bacterial communities to respectively mimic the effects of human host interactions with optimal (healthy) or non-optimal (dysbiotic) microbiome associated with an ascending infection in the female reproductive tract, significant differences in tissue innate immune responses, barrier function, cell viability and protein profile, and mucus composition were detected reminiscent of those observed in vivo. Thus, these Organ Chip models of human cervix provide a physiologically relevant experimental in vitro model to study cervical mucus physiology and its role in human host-microbiome interactions as well as a potential preclinical testbed for development of therapeutic interventions to enhance women's health.

Similar results with minor differences were obtained using epithelial cells isolated from three donors each from a different ethnic background (African American, Hispanic, and Caucasian).

Project description:Modulation of mucus production by the human ecto- and endo-cervical epithelium by steroid hormones and associated interactions with commensal microbiome play a central role in the physiology and pathophysiology of the female reproductive tract. Here, we show that in a human organ-on-a-chip model of cervix (Cervix Chip), use of continuous fluid flow promotes ecto-cervical differentiation, whereas use of periodic flow including periods of stasis stimulated endo-cervical specialization. Continuous flow exhibited significant upregulation of genes associated with ectocervical epithelial phenotype whereas the same cells cultured in the same medium under periodic flow or under static conditions in Transwell inserts upregulated genes more closely associated with the endocervical epithelial phenotype. Similar results with minor differences were obtained using epithelial cells isolated from three donors each from a different ethnic background (African American, Hispanic, and Caucasian).

Project description:The aim of this study was to identify hormonally regulated genes and their related biological pathways in the rhesus macaque cervix during the menstrual cycle. The cervix is the gateway for gamete passage, which is driven by hormonal regulation with progesterone (P) suppressing the passage of gametes. Contraceptives that are progesterone based change the cervix. Progestogen only contraception is reported to act by suppressing ovulation and/or altering cervical mucus secretion. In order to further investigate novel contraceptive targets and their pathways, a microarray was used to discover genes in the cervix that are suppressed under varying lengths of exposure to progesterone throughout an artificial menstrual cycle.
