Abstract
Ovarian aging leads to diminished fertility, dysregulated endocrine signaling and increased chronic disease burden. These effects begin to emerge long before follicular exhaustion. Female humans experience a sharp decline in fertility around 35 years of age, which corresponds to declines in oocyte quality. Despite a growing body of work, the field lacks a comprehensive cellular map of the transcriptomic changes in the aging mouse ovary to identify early drivers of ovarian decline. To fill this gap we performed single-cell RNA sequencing on ovarian tissue from young (3-month-old) and reproductively aged (9-month-old) mice. Our analysis revealed a doubling of immune cells in the aged ovary, with lymphocyte proportions increasing the most, which was confirmed by flow cytometry. We also found an age-related downregulation of collagenase pathways in stromal fibroblasts, which corresponds to rises in ovarian fibrosis. Follicular cells displayed stress-response, immunogenic and fibrotic signaling pathway inductions with aging. This report provides critical insights into mechanisms responsible for ovarian aging phenotypes. The data can be explored interactively via a Shiny-based web application.

Abstract
For decades, most studies of ovarian aging have focused on its functional units, known as follicles, which include oocytes and granulosa cells. However, in the ovarian stroma, there are a variety of somatic components that bridge the gap between general aging and ovarian senescence. Physiologically, general cell types, microvascular structures, extracellular matrix, and intercellular molecules affect folliculogenesis and corpus luteum physiology alongside the ovarian cycle. As a result of damage caused by age-related metabolite accumulation and external insults, the microenvironment of stromal cells is progressively remodeled, thus inevitably perturbing ovarian physiology. With the established platforms for follicle cryopreservation and in vitro maturation and the development of organoid research, it is desirable to develop strategies to improve the microenvironment of the follicle by targeting the perifollicular environment. In this review, we summarize the role of stromal components in ovarian aging, describing their age-related alterations and associated effects. Moreover, we list some potential techniques that may mitigate ovarian aging based on their effect on the stromal microenvironment.

Regulatory T Cells Overexpressing Peli1 Show Better Efficacy in Repairing Ovarian Endocrine Function in Autoimmune Premature Ovarian Insufficiency. J Transl Med 2023; 103:100005.

Abstract
Regulatory T (Treg) cell dysfunction is involved in the pathogenesis of autoimmune premature ovarian insufficiency (POI). Adoptive transfer of Treg cells has been shown to be effective in the treatment of autoimmune POI in mice. However, the therapeutic effect of Treg cell therapy is limited because the phenotype and function of Treg cells is not properly maintained when they are reinfused in an inflammatory environment. Therefore, enhancing the function of Treg cells using genetic engineering is of great significance for improving the efficacy of Treg cells in the treatment of immune diseases. In this study, we investigated the role of the E3 ubiquitinated ligase Pellino 1 (Peli1) in the proliferation and immunosuppressive function of Treg cells and the therapeutic effect of Treg cells overexpressing Peli1 on autoimmune POI. The results showed that the overexpression of Peli1 promoted cell proliferation and enhanced the immunosuppressive function of Treg cells in vitro. After the adoptive transfer of Treg cells overexpressing Peli1 in autoimmune POI mice, the apoptosis rate of ovarian granulosa cells declined. The levels of the inflammatory inhibitors interleukin 10 and transforming growth factor-β as well as the ovarian hormone estradiol were elevated. The number of primordial, primary, secondary, and mature follicles was restored to a certain extent compared with those in control subjects. These results revealed that the adoptive transfer of Treg cells overexpressing Peli1 promoted its efficacy against zona pellucida protein 3 peptide-induced POI, which provides new insights into the treatment of autoimmune POI.

Abstract
PURPOSE Miscarriage is one of the most common complications of pregnancy. Although chromosomal abnormalities of the embryo is a well-known cause of miscarriage, a lot of cases remain unexplained, with immunologic and vascular growth alterations being considered as probable causes. Chemokines are produced by a variety of cells and exhibit several functions including both pro and anti-angiogenic properties. In this study, we investigated the role of the angiogenic and angiostatic chemokines in placenta and decidua tissues from spontaneous and induced abortions. METHODS Total RNA was extracted from the placenta and decidua tissues, which was then purified and converted into cDNA. Real-time PCR was then performed for the expression of the angiogenic CCL2, CCL5, CCL20, CXCL1, CXCL2, CXCL3, CXCL5, CXCL6, CXCL7, CXCL8 and CXCL4, and the angiostatic CXCL9, CXCL10, CXCL11, CXCL12 and CXCL14 and results were then statistically analyzed. RESULTS Regarding the placenta, CXCL7 (2.29-fold, 2.16-2.38, p < 0.05), CXCL4 (1.01-fold, 0.74-4.447, p < 0.05), CXCL9 (0.87-fold, 0.43-1.34, p < 0.05) and CXCL11 (0.31-fold, 0.22-0.45, p < 0.05) were altered in spontaneous abortions. CCL2, CCL5, CXCL2-3, CXCL8, CXCL10, CXCL12 and CXCL14 were not statistically significant altered. Regarding the decidua, CXCL7 (7.13-fold, 6.32-7.54, p < 0.01), CXCL8 (11.02-fold, 8.58-13.45, p < 0.05), CCL20 (1.21-fold, 0.29-1.89, p < 0.05) and CXCL9 (5.49-fold, 3.67-6.39, p < 0.05) were overexpressed in spontaneous abortions. CXCL2-4, CCL2, CCL5, CXCL10-12 and CXCL14 did not show any differences. The expression of the chemokines CXCL1, CXCL5-6 was absent in either tissue or group. CONCLUSION Our results show that the overexpression of angiostatic and diminished expression of angiogenic chemokines takes place in the placenta and decidua of spontaneous abortions, suggesting that dysregulation of angiogenesis could be a contributive factor to the pathogenesis of miscarriage.

Abstract
PROBLEM This study aimed to identify subsets of regulatory T cells (Tregs) associated with ovarian aging and determine whether they can be used as markers of reproductive aging. METHOD This prospective cohort study was conducted among women of reproductive age. Basic physiological characteristics, reproductive hormones, Treg cell subsets, and correlations between these parameters were assessed. The POSEIDON criteria was used to identify women with low reproductive potential. RESULTS The percentages of HLA-DR+ CD45RA- Tregs and CD28- Treg-like cells significantly increased with age. Women between 40 and 49 years had significantly higher percentages of HLA-DR+ CD45RA- Tregs and CD28- Treg-like cells than those at 20-29, 30-34, and 35-39 years old. Age positively correlated with FSH levels and the percentages of HLA-DR+ CD45RA- Tregs and CD28- Treg-like cells, but inversely correlated with antral follicle count (AFC) and AMH levels. Interestingly, a positive correlation was found between the percentages of HLA-DR+ CD45RA- Tregs and FSH levels, whereas an inverse correlation was found between those of HLA-DR+ CD45RA- Tregs and AFC or AMH levels. Furthermore, a significant positive correlation was observed between the percentages of CD28- Treg-like cells and AFC. Based on POSEIDON criteria, women with the percentages of HLA-DR+ CD45RA- Tregs and CD28- Treg-like cells above reference value ranges were assigned to the low prognosis groups. CONCLUSION These findings suggest that HLA-DR+ CD45RA- Tregs and CD28- Treg-like cells can be used as immunologic markers of reproductive aging, which helps clinicians identify women with low reproductive potential and establish individualized therapeutic strategies.

Abstract
Reproductive ageing in females is defined by a progressive decline in follicle number and oocyte quality. This is a natural process that leads to the loss of fertility and ovarian function, cycle irregularity and eventually menopause or reproductive senescence. The factors that underlie the natural depletion of follicles throughout reproductive life are poorly characterised. It has been proposed that inflammatory processes and fibrosis might contribute to ovarian ageing. To further investigate this possibility, we evaluated key markers of inflammation and immune cell populations in the ovaries of 2, 6, 12 and 18-month-old C57BL/6 female mice. We report that the decrease in follicle numbers over the reproductive lifespan was associated with an increase in the intra-ovarian percentage of CD4 + T cells, B cells and macrophages. Serum concentration and intra-ovarian mRNA levels of several pro-inflammatory cytokines, including IL-1α/β, TNF-α, IL-6, and inflammasome genes ASC and NLRP3, were significantly increased with age. Fibrosis levels, as determined by picrosirius red staining for collagen I and III, were unchanged up to 18 months of age. Collectively, these data suggest that inflammation could be one of the mechanisms responsible for the age-related regulation of follicle number, but the role of fibrosis is unclear. Further studies are now required to determine if there is a causative relationship between inflammation and follicle depletion as females age.

Abstract
This study was designed to investigate the protective effect of CD4+ CD25+ regulatory T cells (Tregs) against zona pellucida glycoprotein 3 peptide (pZP3) immunization-induced premature ovarian insufficiency (POI) in mice. A mouse POI model was induced by two subcutaneous injections of pZP3 (50 nmol/L). Mice in the pZP3-Treg group were intraperitoneally injected with 5 × 105 CD4+ CD25+ Tregs after the POI model was established. Sex hormone levels, follicle numbers, apoptotic events, and the Akt/FOXO3a signaling pathway molecules in the ovaries were assessed. Compared with control group, the weight of ovaries in both pZP3 group and pZP3-Treg group was decreased and no difference was found between them. The number of follicles in the Treg transferred mice, like in pZP3 group, was significantly reduced compared to the control group, but showed a modest improvement when compared the pZP3 group alone. Significantly lower serum concentrations of follicle-stimulating hormone, luteinizing hormone, and anti-zona pellucida antibodies (AZPAbs) were found, while the concentrations of estradiol and anti-Mullerian hormone increased. In mechanism, Treg cell transfer to ZP3 treated mice restored the levels of Caspase3 to control levels, and partially restored Bax, however, had no effect on Bcl-2. Moreover, Treg cell transfer to ZP3 treated mice partially restored the levels of Akt and FOXO3a, and partially restored the ratios of p-Akt/Akt and p-FOXO3a/FOXO3a. In conclusion, Treg cells improved some aspects of ZP3-induced POI which may be mediate by suppressing ovarian cells apoptosis and involving the Akt/FOXO3a signaling pathway. Therefore, Treg cells may be protective against autoimmune POI.

Abstract
During pregnancy, the fetus that grows within the maternal uterus is not rejected by the maternal immune system. To enable both tolerance towards the fetus and defence against pathogens, modifications of the maternal immune system occur during gestation. These modifications are able to bring about a natural improvement in disease activity of some autoimmune diseases, such as rheumatoid arthritis (RA). Various mechanisms of the immune system contribute to the phenomenon of pregnancy-related improvement of RA, and the cessation of these immunomodulatory mechanisms after delivery correlates with postpartum disease flare. HLA disparity between mother and fetus, glycosylation of IgG, immunoregulatory pathways, and alterations in innate and adaptive immune cells and their cytokines have important roles in pregnancy and in pregnancy-related amelioration of RA.

Abstract
Autoimmune ovarian disease (AOD) is considered to be a major cause of premature ovarian failure (POF). The immunomodulatory properties of human amniotic epithelial cells (hAECs) have been studied in many disease models. We previously reported that hAECs restored ovarian function in chemotherapy-induced POF mice, but the immunomodulatory mechanism of hAECs is still unclear. To investigate the effect of hAECs on recipient mice, especially on regulatory Treg cells, hAECs and hAEC-conditioned medium (hAEC-CM) were intravenously injected into AOD mice immunized with zona pellucida protein 3 peptides (pZP3). Ovarian function was evaluated through estrous cycle, hormone secretion, follicle development, and cell apoptosis analysis. Immune cells including CD3, CD4, CD8 and Treg cells in the spleens were tested by flow cytometry. To elucidate the effect of hAEC-CM on macrophage function, inflammation model in vitro was established in RAW264.7 cells induced by lipopolysaccharide (LPS). hAECs and hAEC-CM regulated estrous cycles, promoted follicle development, ameliorated cell apoptosis and fibrosis in ovaries of AOD mice. In addition, hAECs significantly reversed the decrease of pZP3-induced Treg cells in the spleens. In vitro, hAEC-CM significantly inhibited the inflammatory reaction induced by LPS in RAW264.7 cells via up-regulating the expression of M2 macrophage genes. Further study demonstrated that hAEC-secreted transforming growth factor-beta and macrophage inhibitory factor played important roles in the macrophage polarization and migration under inflammatory stimulation. Taken together, hAECs restored ovarian function by up-regulating Treg cells in the spleens and reduced the inflammatory reaction via modulating the activated macrophage function in a paracrine manner in the ovaries of AOD mice.

Abstract
Anti-N-methyl-D-aspartate-receptor (NMDAR) encephalitis is an autoimmune disorder characterized by memory deficits, psychiatric symptoms, and autonomic instability. The lack of suitable biomarkers targeting anti-NMDAR encephalitis makes the immunotherapy and prognosis challenging. In this study, we found that the Th17 cells were significantly accumulated in the cerebrospinal fluid (CSF) of anti-NMDAR encephalitis patients than that of control individuals. The concentration of the cytokines and chemokines including interleukin (IL)-1β, IL-17, IL-6, and CXCL-13 were significantly increased in the CSF of anti-NMDAR encephalitis patients. IL-6 and IL-17 were found to promote the differentiation of CD4+ T cells into Th17 lineage. The chemotaxis assay showed that CCL20 and CCL22 play essential roles in the migration of Th17 cells. Notably, the correlation between the expression of IL-17 and the outcome of anti-NMDAR encephalitis patients was analyzed. The data showed that high level of IL-17 was significantly correlated with the limited response to the treatment and relapse of anti-NMDAR encephalitis patients. Our results suggested the potential important involvement of IL-17 in anti-NMDAR encephalitis.
