Accumulating evidence suggests that antigen-antibody-mediated immune responses may be involved in the pathogenesis of various cardiovascular conditions; however, whether these associations reflect causal relationships has long remained unclear. To address this question, we conducted a bidirectional two-sample Mendelian randomization study leveraging summary-level data from genome-wide association studies. In this analysis, 46 antibody-mediated immune traits were evaluated as exposures, and 11 cardiovascular outcomes, including aortic aneurysm, aortic valve stenosis, atrial fibrillation, coronary artery disease, dilated cardiomyopathy, atrioventricular block, heart failure with reduced ejection fraction, hypertrophic cardiomyopathy, infective endocarditis, myocarditis, and pericarditis, were examined as outcomes. Our results revealed several significant causal associations: genetically predicted higher levels of Epstein-Barr virus EBNA-1 antibodies were associated with increased risks of myocarditis and aortic valve stenosis, while elevated VCA p18 antibody levels were linked to a higher risk of myocarditis. Furthermore, increased antibody levels against BK polyomavirus VP1 were causally associated with greater risks of aortic valve stenosis and dilated cardiomyopathy. In contrast, higher levels of antibodies against varicella-zoster virus glycoproteins and human herpesvirus 6 IE1B were associated with reduced risks of myocarditis and aortic aneurysm, respectively.

Endovascular mechanical thrombectomy (EVT) has revolutionized stroke treatment by enabling rapid recanalization of occluded cerebral vessels. However, a significant proportion of patients experience futile recanalization, where successful vessel reopening fails to translate into favorable functional outcomes. Emerging evidence highlights ferroptosis, a regulated form of cell death driven by iron-dependent lipid peroxidation, as a critical mechanism contributing to neuronal damage in ischemic stroke, particularly during reperfusion injury. This comprehensive review examines the intricate relationship between ferroptosis and futile recanalization following mechanical thrombectomy. We systematically explore the molecular mechanisms underlying ferroptosis in the context of cerebral ischemia-reperfusion injury, including iron metabolism dysregulation, lipid peroxidation cascades, glutathione depletion, and mitochondrial dysfunction. Multiple factors contribute to futile recanalization, including patient demographics (age, comorbidities), stroke characteristics (severity, infarct volume, collateral status), procedural variables (time to treatment, recanalization quality), and post-procedural complications (hemorrhagic transformation, reperfusion injury). We review current predictive models, including nomograms and machine learning algorithms, that integrate clinical, radiological, and biomarker data to stratify patient risk. Importantly, we discuss potential therapeutic interventions targeting ferroptosis pathways, such as iron chelators, lipophilic antioxidants, and ferroptosis-specific inhibitors. The integration of ferroptosis biomarkers into predictive models may enhance risk stratification and guide personalized treatment strategies. Future research should focus on validating ferroptosis-targeted therapies in clinical trials, developing real-time monitoring techniques, and establishing standardized protocols for neuroprotective interventions during mechanical thrombectomy. A deeper understanding of ferroptosis mechanisms and their contribution to futile recanalization may pave the way for novel therapeutic approaches to improve stroke outcomes.</p>","PeriodicalId":12163,"journal":{"name":"Experimental Biology and Medicine","volume":"251 ","pages":"10997"},"PeriodicalIF":3.8,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13175941/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147962681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sixty male Sprague-Dawley rats were randomized into five groups: control, doxorubicin (DOX), bisoprolol (1.0 mg/kg/d), sacubitril valsartan (30 mg/kg/d), and combination therapy. All groups except control received intraperitoneal DOX (2.5 mg/kg weekly for 5 weeks).
