Front Immunol 2023; 14:1126103. [PMID: 37901230 PMCID: PMC10603295 DOI: 10.3389/fimmu.2023.1126103] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Accepted: 09/28/2023] [Indexed: 10/31/2023] Open
Abstract
Background Antiphospholipid syndrome (APS) is a group of clinical syndromes of thrombosis or adverse pregnancy outcomes caused by antiphospholipid antibodies, which increase the incidence of in vitro fertilization failure in patients with infertility. However, the common mechanism of repeated implantation failure (RIF) with APS is unclear. This study aimed to search for potential diagnostic genes and potential therapeutic targets for RIF with APS. Methods To obtain differentially expressed genes (DEGs), we downloaded the APS and RIF datasets separately from the public Gene Expression Omnibus database and performed differential expression analysis. We then identified the common DEGs of APS and RIF. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses were performed, and we then generated protein-protein interaction. Furthermore, immune infiltration was investigated by using the CIBERSORT algorithm on the APS and RIF datasets. LASSO regression analysis was used to screen for candidate diagnostic genes. To evaluate the diagnostic value, we developed a nomogram and validated it with receiver operating characteristic curves, then analyzed these genes in the Comparative Toxicogenomics Database. Finally, the Drug Gene Interaction Database was searched for potential therapeutic drugs, and the interactions between drugs, genes, and immune cells were depicted with a Sankey diagram. Results There were 11 common DEGs identified: four downregulated and seven upregulated. The common DEG analysis suggested that an imbalance of immune system-related cells and molecules may be a common feature in the pathophysiology of APS and RIF. Following validation, MARK2, CCDC71, GATA2, and KLRC3 were identified as candidate diagnostic genes. Finally, Acetaminophen and Fasudil were predicted as two candidate drugs. Conclusion Four immune-associated candidate diagnostic genes (MARK2, CCDC71, GATA2, and KLRC3) were identified, and a nomogram for RIF with APS diagnosis was developed. Our findings may aid in the investigation of potential biological mechanisms linking APS and RIF, as well as potential targets for diagnosis and treatment.

Matsumi H. Evidence for Correlation between Novel Autoantibody against Phospholipid Named Neoself Anti- β2-GPI/HLA-DR Antibody and Complement Consumption in Infertile Patients. Obstet Gynecol Int 2023; 2023:1318553.

Abstract
Impaired implantation is one of the causes of infertility. It occurs under vital inflammatory status due to immune hyperactivation. In the innate immune system, the inflammatory response to pathogenic stimuli is initiated by complement activation. Minimal vasculitis associated with complement consumption in infertile patients may be an underlying mechanism for impaired implantation. Antiphospholipid antibodies regulate the inflammatory response. Recently, a novel autoantibody (neoself antibody) against a complex of β2-GPI and HLA class II molecules (β2-GPI/HLA-DR) has been reported to be an independent autoantibody associated with aPLs. This study investigated the relationship between neoself antibodies and complement consumption in infertile patients with impaired implantation. It was found that decreased C4 levels were strongly related to the increased neoself antibody titers in the serum among those patients whose antibody titers were not as high. On the contrary, serum levels of CH50 and CRP are not correlated with them. These results suggest that neoself antibodies might indicate low-grade inflammation, which causes endometrial vasculitis in impaired implantation of infertile patients.

Superfertility and subfertility in patients with recurrent pregnancy loss: A comparative analysis of clinical characteristics and etiology based on differences in fertile ability. J Reprod Immunol 2023; 159:104129. [PMID: 37598542 DOI: 10.1016/j.jri.2023.104129] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Revised: 08/02/2023] [Accepted: 08/03/2023] [Indexed: 08/22/2023]
Abstract
This study aimed to elucidate the etiologies of and risk factors for recurrent pregnancy loss (RPL) according to fertile ability, focusing on the differences between superfertile and subfertile patients. This retrospective observational study included 828 women with RPL between July 2017 and February 2020. Patients were divided into three groups based on time to pregnancy (TTP): superfertile (SUP) (TTP ≤3 months for all previous pregnancies), subfertile (SUB) (previous TTP ≥12 months and use of assisted reproductive technology [ART]), and Normal (N) (TTP >3 or <12 months without ART). All patients were assessed for uterine anatomy, antiphospholipid antibodies (APAs), thyroid function, and thrombophilia. Of the 828 patients, 22%, 44%, and 34% were assigned to the SUP, SUB, and N groups, respectively. The mean ages were 33.9, 38.2, and 35.9 years in the SUP, SUB, and N groups, respectively, revealing a significant difference (P < 0.001). The anti-CL β2GPI antibody positivity rate was significantly higher in the SUP group (4.6%) than in the N group (0.8%; P = 0.016). The prevalence of APA positivity was lowest in the N group. Overall, the clinical characteristics and etiologies of RPL associated with superfertility and subfertility were strikingly similar, with comparable positivity rates after adjusting for maternal age. Further investigation including chromosomal analysis of products of conception is needed to elucidate the clinical impact of differences in fertility on patients with RPL.

Hu S, Sun Z, Li B, Zhao H, Wang Y, Yao G, Li X, Bian X, Li TC, Vankelecom H, Sun Y. iTRAQ-based Proteomic Analysis Unveils ACSL4 as a Novel Potential Regulator of Human Endometrial Receptivity. Endocrinology 2023; 164:6991315. [PMID: 36652382 DOI: 10.1210/endocr/bqad012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 12/07/2022] [Accepted: 12/08/2022] [Indexed: 01/19/2023]
Abstract
Competent endometrial receptivity is a prerequisite for successful embryo implantation. Identification of novel key molecules involved in endometrial receptivity is essential to better interpret human implantation and improve pregnancy rates in assisted reproduction treatment. Isobaric tags for relative and absolute quantitation (iTRAQ)-based proteomics was performed to profile the proteomes of the prereceptive (luteinizing hormone [LH] + 2, n = 4) and receptive (LH + 7, n = 4) endometrial tissues. A total of 173 differentially expressed proteins (DEPs) between LH + 2 and LH + 7 endometrial samples were identified. Integrated analysis of the proteomic data and published transcriptomic data was performed to identify the concordant DEPs with differential expression at both the messenger RNA and protein levels. Protein-protein interaction (PPI) network analysis was performed on concordant DEPs. We first identified 63 novel concordant DEPs and 5 hub proteins (ACSL4, ACSL5, COL1A1, PTGS1, and PLA2G4F) between LH + 2 and LH + 7 endometrial samples. ACSL4 was predominantly expressed in endometrial epithelial cells and its expression was significantly upregulated by progesterone in the LH + 7 endometrium and significantly downregulated in repeated implantation failure patients. Knockdown of ACSL4 in endometrial epithelial cells induced the downregulation of endometrial receptivity markers (HOXA10, COX2, and LIF) and the significant decrease of implantation rate during in vitro implantation analysis. This study provides the first gel-independent quantitative proteomes of the LH + 2 and LH + 7 human endometrium using iTRAQ technology. The identified concordant DEPs and hub proteins open a new avenue for future studies aimed at elucidating the underlying mechanisms governing endometrial receptivity. ACSL4 was identified as a novel regulatory molecule in the establishment of endometrial receptivity and might play important roles during implantation.

Abstract
Despite the advances in the field of reproductive medicine, implantation failure represents a challenging condition affecting 10-30% of patients subjected to in vitro fertilization (IVF). Research has focused on the identification of molecules playing crucial roles in endometrial receptivity, with the aim of designing predictive tools for efficient detection of the implantation window. To that end, novel molecular genomic and transcriptomic approaches have been introduced as promising tools to enable personalized approaches with the aim of optimizing embryo transfer dating. However, the clinical value of these approaches remains unclear. The aim of this study is to provide a systematic review and critical analysis of the existing evidence regarding the employment of commercially available novel approaches to evaluate endometrial receptivity. An Embase and PubMed/Medline search was performed on 1 February 2022. From the 475 articles yielded, only 27 were included and analyzed. The considerable heterogeneity of the included articles indicates the uniqueness of the implantation window, showcasing that the optimal time for embryo transfer varies significantly between women. Moreover, this study provides information regarding the technical aspects of these advanced molecular tools, as well as an analysis of novel possible biomarkers for endometrial receptivity, providing a basis for future research in the field.

Abstract
Recurrent implantation failure (RIF) is characterized by the absence of implantation after high-grade embryos are transferred to the endometrium by at least three in vitro fertilization cycles. It is one of the most important factors contributing to reproductive failure. After numerous barriers have been overcome to obtain good-quality embryos, RIF causes extreme distress and frustration in women and couples. In recent years, significant progress has been made in understanding how inflammatory factors, which include pro-inflammatory factors, anti-inflammatory factors, chemokines, and other molecules, contribute to RIF. Immunological abnormalities, hypercoagulability, and reproductive diseases are considered potential causes of RIF. In alloimmune disorders, inflammatory factors can affect the success rate of embryo implantation by altering T helper (Th)1/Th2 and Th17/regulatory T cell ratios and causing imbalances of uterine natural killer cells and macrophages. Autoimmune disorders can also lead to RIF. Inflammatory factors also play key roles in RIF-related disorders such as hypercoagulability, chronic endometritis, adenomyosis, hydrosalpinx, and endometriosis. This review focuses on the roles of inflammatory factors in RIF, including immune factors, blood hypercoagulable states, and reproductive diseases such as chronic endometritis, adenomyosis, hydrosalpinx, and endometriosis. It also summarizes the different treatments according to the causes of RIF and discusses the efficacy of sirolimus, peripheral blood mononuclear cells, low-dose aspirin combined with low-molecular-weight heparin, blocking interleukin-22, and gonadotropin-releasing hormone agonists in the treatment of RIF.

Abstract
OBJECTIVE The aim of our study was to evaluate obstetric outcome of women affected by idiopathic infertility showing persistently positive antiphospholipid antibodies (aPL). METHODS : From 2000 consecutive patients undergoing ART, we selected 151 (7.55%) clinical records of patients affected by idiopathic infertility undergoing ICSI and showing positive aPL. RESULTS Persistently positive aPL were found in 64/151 (42.38%) of the patients: in 34/64 (53.12%) at medium/high titers (group A) and in 30/64 (46.87%) at low titers (group B). Primary or secondary antiphospholipid syndrome (APS) was diagnosed in 25% of the patients, whereas 37.5% women showed clinical and/or laboratory features suggestive of APS, but not fulfilling clinical or laboratory classification criteria. Idiopathic infertility was the sole symptom in 31.25%. In 55% of these infertile patients, a history of recurrent failures of assisted reproductive techniques (ART) was also observed. Eighty-eight percent (88.88%) of women became pregnant and 77.77% gave birth. During pregnancy, an increase of aPL values was observed in 29.41% women of group B. CONCLUSIONS A careful selection of patients allowed us to confirm that women affected by idiopathic infertility show a high prevalence of aPL, suggesting that these autoantibodies can also affect conception. Considering pregnancy complications and thrombotic risk related to ovarian stimulation, measuring aPL can represent a valid tool to identify among infertile women undergoing ART those at higher risk of pregnancy complications potentially life-threatening for mother and the fetus. In such patients, an accurate diagnosis and an adequate therapy are related to a better ART outcome.

Abstract
Polycystic ovary syndrome (PCOS) is a neuroendocrine heterogeneous disease that frequently occurs in women of reproductive age, causing serious damage to the fertility, quality of life, and physical and mental health of patients. The current studies have proved that satisfactory endometrial receptivity is one of the conditions that must be met during the process of spermatovum position, adhesion and invasion, as well as the subsequent blastocyst division and embryo development. Women with PCOS may suffer a series of pathological processes such as changes in the expression levels of hormones and related receptors, imbalances in the proportion of miscellaneous cytokines, insulin resistance, low-grade chronic inflammation and endometrial morphological changes, which will damage endometrial receptivity from various aspects and obstruct fertilized egg nidation and embryonic development, thus causing adverse reproductive health events including infertility and abortion. This article reviews the research progress about characteristics and related influencing factors of endometrial receptivity in PCOS patients.
