However, research in reproductive health in Germany has remained limited, with significant gaps that demand attention. To address these gaps, there is an urgent need for focused research, particularly among emerging scientists in academic medical institutions. In response to this need, the Federal Ministry of Education and Research (BMBF) established five interdisciplinary centers dedicated to reproductive health in late 2023, following the ISIR 2023 conference. These centers include SRHOO at UKE, which explores the intersection of obesity and reproductive health; LE-REP, studying the long-term effects of fertility treatments; CEPRE, supporting healthy pregnancies through clinical and research collaboration; ReproTrack.MS, investigating male infertility at the molecular level; and FePro-Ulm, advancing fertility preservation techniques. This special issue showcases research from these centers, providing valuable insights into innovative treatments and the influence of lifestyle on reproductive health. The initiative also seeks to inspire young scientists to pursue careers in reproductive medicine and promote international collaboration aimed at improving maternal and child health worldwide.</div></div>","PeriodicalId":16963,"journal":{"name":"Journal of Reproductive Immunology","volume":"170 ","pages":"Article 104618"},"PeriodicalIF":2.9,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144321996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interleukin-33 plays an important role in the cellular activation of mast cells and natural killer cells. This study investigated the endometrial IL-33/<em>ST2</em> axis and its role in mast cell activation in women with RPL and RIF during the mid-luteal phase. Gene expression of <em>ST2</em> was significantly decreased in RPL and RIF patients compared to normal fertile controls (Mean ± SE, 0.46 ± 0.08, 0.44 ± 0.09, 1.25 ± 0.46, P < 0.007). No differences were found in <em>ST2/IL-33</em> mRNA expression ratios, IL-33, and <em>TPSAB1</em> mRNA expression. Western blot analysis revealed a decreased amount of membrane-bound ST2 in RPL and RIF in the endometrium compared to controls (0.09 ± 0.02, 0.12 ± 0.08, 0.28 ± 0.07, P < 0.05). No difference was found in soluble ST2 levels. Evaluation of the ST2/IL-33 protein ratios showed no significance between groups. No differences were found in IL-33 or tryptase protein levels. A correlation analysis was performed between mRNA expression levels of IL-33, ST2, and <em>TPSAB1</em> in relation to genes associated with decidualization; IL-33 was correlated with <em>CD3E, GZMB, NCAM1, PRF1, RORC, SGK1,</em> and <em>TGFB1</em> in the RPL group and associated with <em>CDKN2A, IL18, SLC2A1</em>, and <em>VEGFA</em> in controls. Decreased amount of membrane-bound ST2 may lead to the decreased physiologic activity of IL-33 on immune cells within patients with RPL and RIF; this may lead to alterations in uNK cells contributing to immune dysregulation in the endometrium.</div></div>","PeriodicalId":16963,"journal":{"name":"Journal of Reproductive Immunology","volume":"170 ","pages":"Article 104619"},"PeriodicalIF":2.9,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144321995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sensitivity analyses were performed to ensure result robustness. Multivariable MR was also used to control for confounding among immune cells. Results showed that 16 immunophenotypes were positively associated with adenomyosis (p < 0.05, OR > 1), while 10 had a negative correlation (p < 0.05, OR < 1). Reverse MR revealed 16 positive and 4 negative correlations with adenomyosis (P < 0.05, OR > 1 or < 1). Multivariable MR identified 5 risk factors and 8 protective factors for adenomyosis (P < 0.05, OR > 1 or < 1).
