However, its clinical translation is often hindered by excessive accumulation in reticuloendothelial system organs, particularly the liver, which can lead to radiation-induced toxicity. Herein, an in vivo selective radiolabeling strategy is reported that exploits the distinct subcellular fates of nanoparticles in tumors versus liver. A biorthogonal nanosystem composed of trans-cyclooctene (TCO)-functionalized iron oxide nanoparticles (Fe3O4@TCO) and a radiolabeled tetrazine probe (177Lu-DOTA-Tz) is constructed to validate this concept. Owing to the hydrophilic nature, 177Lu-DOTA-Tz cannot penetrate cell membranes, resulting in spatially restricted bioorthogonal labeling in the extracellular space. At tumor sites, Fe3O4@TCO nanoparticles accumulate via the enhanced permeability and retention effect and remain accessible for efficient binding with 177Lu-DOTA-Tz. In contrast, in the liver, nanoparticles are predominantly internalized by liver cells, and its intracellular localization prevents interaction with the probe, thereby minimizing hepatic radiation retention. By harnessing these subcellular distribution differences, the approach achieves selective in vivo radiolabeling and significantly improves the tumor-to-liver radiation ratio. This study provides a biologically informed strategy for designing radiolabeled nanoplatforms with enhanced safety profiles for theranostic applications.","PeriodicalId":113,"journal":{"name":"Advanced Healthcare Materials","volume":" ","pages":"e03438"},"PeriodicalIF":9.6,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145224680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study sought to mitigate this problem by utilizing the patient's blood, serum, or plasma in the transplant. To accomplish this objective, blood additives derived from Sprague-Dawley rats are incorporated within alginate, and human parathyroid cells are encapsulated. The prepared microbeads are monitored for mechanical properties, followed by xenotransplantation into rats for the evaluation of cell function and immunological response. Biodegradation data showed that the structural integrity of the microbeads containing blood and plasma is superior to serum, while the durability of plasma-including microbeads is only comparable to that of the alginate-only group. Plasma-including microbeads released the highest levels of parathyroid hormone (PTH), both in vitro and in vivo. This behavior could be attributed to the beneficial impact of plasma on cellular function while regulating immune response. Blood incorporation provoked an elevated immune response while concurrently offering minimal support to the encapsulated cells. A notable elevation in CCL2 (MCP-1) chemokine levels is observed in both blood and alginate-only microbead groups, correlating with CD68 expression. These findings demonstrated that autologous plasma addition may regulate the immune system, thereby diminishing the risk of rejection in cell transplantations.","PeriodicalId":113,"journal":{"name":"Advanced Healthcare Materials","volume":" ","pages":"e01483"},"PeriodicalIF":9.6,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145224749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are few effective pharmacological interventions targeting muscle atrophy, highlighting the need for new therapeutic strategies. In this study, in vivo self-assembled siRNA is designed to silence myostatin (MSTN), a key regulator of muscle growth and atrophy, aiming to prevent muscle atrophy. Using synthetic constructs and the host liver as a scaffold, the assembly of MSTN-siRNA is guided into muscle-specific peptide MSP-tagged small extracellular vesicles (sEVs). These MSP-tagged sEVs selectively deliver MSTN-siRNA to muscle tissue. Treatment significantly reduces MSTN protein levels in skeletal muscle, promotes muscle mass gain in healthy mice, and protectes skeletal muscles from atrophy in cancer- and dexamethasone-induced muscle atrophy models. Notably, the sEV-encapsulated MSTN-siRNA is produced in a nontoxic, nonimmunogenic, and biocompatible manner.

The development of 3D printing provides a promising solution for corneal tissue engineering, offering precise control over dimensionality, structural organization, and cell-matrix interactions. The choice of biomaterials and printing strategies critically determines the properties of 3D-printed corneal constructs. While prior reviews have summarized general bioinks and techniques, few have addressed cornea-specific benchmarks such as transparency, curvature, and mechanical robustness. This review provides a comprehensive discussion on the current study of 3D printed cornea, with a focus on replicating the biomechanical and optical properties of native human cornea. Key limitations in current fabrication methods are outlined, and recent advancements in 3D bioprinting technologies-many of which have been successfully applied in other tissue engineering contexts-are reviewed for their potential in producing anisotropic, multilayered corneal constructs with high resolution and fidelity. 3D printing human cornea is believed to have strong potential in generating scalable and clinically relevant solutions to overcome the global donor cornea tissue shortage, and 3D printing holds a central role in their development.","PeriodicalId":113,"journal":{"name":"Advanced Healthcare Materials","volume":" ","pages":"e02767"},"PeriodicalIF":9.6,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145211150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gene editing approaches to eradicate HBV by targeting cccDNA face challenges and limitations due to suboptimal editing efficiency and substantial off-target effects. Herein, a combinatorial therapeutic strategy is developed that integrates CRISPR/Cas9-mediated cccDNA disruption with an antisense oligonucleotide (ASO)-targeted degradation of pregenomic RNA (pgRNA). To overcome delivery challenges, a hepatocyte-targeting nanocarrier (UACPG) is engineered, featuring low immunogenicity, high payload capacity, and dual-stimuli responsiveness. The UACPG platform enabled liver-specific delivery through surface-conjugated targeting ligands, followed by on-demand release of Cas9 ribonucleoprotein complexes and ASO via RNase H-dependent degradation and near-infrared (NIR) light activation. The results demonstrated that UACPG can effectively reduce HBV replication and viral antigen levels, while significantly lowering cccDNA in hydrodynamic HBV-infected mouse models, with no significant off-target effects observed. This nanocarrier achieved the spatiotemporally controlled release of gene-editing systems in vitro and in vivo, significantly inhibiting the replication of HBV, thereby establishing an innovative technological platform for developing curative HBV therapies.","PeriodicalId":113,"journal":{"name":"Advanced Healthcare Materials","volume":" ","pages":"e02835"},"PeriodicalIF":9.6,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145211075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, reliable diagnostic markers and therapeutic tools for successfully predicting personalized treatment outcomes with copper inhibition remain elusive. In this study, it is discovered that Yes-associated protein (YAP) expression conferred susceptibility toward cuproptosis. Molecular analyses revealed that YAP inhibition significantly abolished cuproptotic characteristics. Interestingly, YAP inhibition does not affect protein lipoylation but disrupts copper homeostasis. Mechanistically, YAP regulates antioxidant-1 (ATOX1), a copper chaperone, and overexpression of ATOX1 restored cuproptotic sensitivity in YAP-silenced cells. To advance copper-targeting therapy, it is identified that melatonin inhibited YAP signaling and attenuated the expression of copper metabolism-related genes. Furthermore, a copper-based functional nanomaterial, EsMP@Fu is developed, which incorporates melatonin and the cuproptosis inducer elesclomol complex with copper ions (Cu(II)) (Es:Cu). This formulation facilitates cuproptotic cytotoxicity via fucoidan-decorated nanocarrier to enhance the targeted delivery toward tumor cells. In vivo study demonstrated that EsMP@Fu significantly suppressed tumor growth by 60%, with more pronounced effects on distant metastasis and the induction of antitumor immunity.
