Several oligonucleotide aptamers targeting coagulation factors have been developed, and some are undergoing preclinical or clinical evaluation. Among them, anti-thrombin anticoagulant aptamers are promising dual-targeting agents in that, in addition to inhibiting enzyme activity, they may limit thrombin generation by binding to its precursor, prothrombin. In the present study, combined calorimetric and spectroscopic analyses reveal that these aptamers recognize proexosite I of prothrombin and exosite I of thrombin through broadly similar thermodynamic binding mechanisms. Integration of structural small-angle X-ray scattering (SAXS) studies and limited proteolysis assays shows that aptamer binding to proexosite I alters prothrombin structure, shifting the equilibrium from its more abundant closed form to the open conformation. Taken together, these results support the classification of these aptamers as dual-targeting agents capable of recognizing both thrombin and prothrombin and provide guidance for their continued development as anticoagulant therapeutics.</p>","PeriodicalId":19020,"journal":{"name":"Molecular Therapy","volume":" ","pages":"6074-6085"},"PeriodicalIF":11.4,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13673481/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148579362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therapeutic strategies capable of restoring mitochondrial homeostasis in human RGCs remain limited. We established a human retinal ganglion-like cell (RGLC) model of mitochondrial injury and evaluated neuroprotective efficacy of small extracellular vesicles (sEVs) derived from either undifferentiated BRN3B-H9 cells or differentiated lineage-tailored RGLCs. RGLC-derived sEVs (RGLC-sEVs) conferred robust neuroprotection, significantly enhancing neuronal survival, preserving neurite architecture, and mitigating mitochondrial stress following injury. These effects were reproducible in mixed retinal cultures and in an ocular hypertension mouse model of glaucoma, with neuroprotective benefits observed throughout the retinal landscape. Mechanistically, untargeted metabolomic profiling revealed extensive metabolic reprogramming involving oxidative phosphorylation, amino acid utilization, lipid metabolism, and redox regulatory pathways. In vitro tracking studies confirmed efficient uptake of sEVs by injured RGLCs, confirming effective vesicular cargo delivery under conditions that promote neuroprotection and metabolic recovery. Functional bioenergetic analysis further validated restoration of mitochondrial-glycolytic coupling and improved cellular energetic resilience.

Moreover, many patients who receive ex vivo-manufactured CD19 CAR T cells do not achieve durable responses, suggesting that the expansion and persistence of CAR T cells may need improvement, and/or that strategies targeting alternative antigens may be needed for patients who are refractory to or relapse following treatment with CD19-directed therapies.
