Myasthenia gravis (MG) is an autoimmune disease in which regulatory T cells (Tregs) exhibit reduced numbers and functional defects, with decreased expression of the Treg cell-specific transcription factor Foxp3. Our previous study identified an abnormally high expression of miR-125a-5p in thymoma-associated myasthenia gravis, however, the involvement of miR-125a-5p in the pathogenesis of myasthenia gravis in vivo is unclear. In this study, we explored the role of thymic miR-125a-5p abnormalities in the pathogenesis of myasthenia gravis by establishing an experimental autoimmune myasthenia gravis model. Muscle strength score, low-frequency repetitive nerve stimulation, and serum acetylcholine receptor antibody were performed. The relative expression of miR-125a-5p and Foxp3 in the thymus and spleen was quantified, and the percentage of Treg cells, the levels of the inhibitory cytokines IL-10 and TGF-β1, and the proliferative capacity of splenic T lymphocytes were detected. Our findings revealed significant upregulation of miR-125a-5p expression in myasthenia gravis models. Reducing miR-125a-5p levels alleviated muscle weakness symptoms, elevated Foxp3 expression, enhanced the number of Treg cells, elevated the levels of the Treg-associated inhibitory cytokines IL-10 and TGF-β1, and inhibited the proliferative function of splenic T lymphocytes. The opposite result was obtained when miR-125a-5p was overexpressed. These results suggest that miR-125a-5p can inhibit Foxp3 expression, leading to a decrease in the number and abnormal function of Treg cells. Thus, our findings suggest that miR-125a-5p participates in the pathogenesis of myasthenia gravis by targeting Foxp3 to regulate the function of Treg cells, providing new insights to explore the immunoregulatory mechanisms of miR-125a-5p in myasthenia gravis.</div></div>","PeriodicalId":13413,"journal":{"name":"Immunology letters","volume":"276 ","pages":"Article 107050"},"PeriodicalIF":3.3,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144257927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This functional plasticity makes ILC attractive targets for immunotherapy. Furthermore, their slow proliferation enables them to survive anti-proliferative radiation therapy and chemotherapy, which may support continuous immune surveillance of breast cancer tissue. However, this same resilience poses a significant challenge, as surviving ILC could contribute to tumor persistence or recurrence. Additionally, anti-estrogen therapy, chemotherapy and immune checkpoint inhibitors, commonly used in breast cancer treatment, may interfere with ILC function, either dampening their anti-tumor potential or enhancing their pro-tumor activities.
