The aim of this work was a comparative study of the influence of intracellularly and extracellularly localized polydopamine-containing materials on the heat-mediated facilitation of neuronal differentiation. Scaffolds made from aligned nylon nanofibers, mimicking the structure of the extracellular matrix, were used as a matrix for immobilizing photothermal nanoparticles. The composite material combines an ultrastructure capable of accelerating and directing the growth of nerve extensions and the ability for controlled thermal remote influence on cell activity under NIR irradiation within the biological transparency range. The materials demonstrated high photostability and biocompatibility without the drawbacks associated with intracellular nanoparticle delivery, such as cytotoxicity and gradual elimination from the body. The immobilization of thermoplasmonic elements on the fibers surface allows for more controlled and manageable heating compared to intracellular introduction of PDA nanoparticles. The fibrous material's ultrastructure directs neurite growth and enhances elongation. Photothermal stimulation further enhances this process by increasing the proportion of cells with longer neurites, thus enhancing neuronal differentiation. Composite nanomaterials can be used for neuromodulation, managing the functional activity of cells, particularly where directed growth is needed, such as in the regeneration of peripheral nerve tissue. This work brings us closer to the creation of smart materials that are biocompatible and easy to manufacture for developing scalable thermal stimulation techniques in regenerative medicine.</div></div>","PeriodicalId":22019,"journal":{"name":"Smart Materials in Medicine","volume":"6 1","pages":"Pages 8-22"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143610204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, there is an urgent unmet clinical need for novel FSGS therapies. Recognizing potent efficacy of GCs in managing FSGS, we proposed the use of a polyethylene glycol (PEG)-based nephrotropic dexamethasone (Dex) prodrug (ZSJ-0228 or PEG-Dex) to mitigate the GC side effects. The focus of the present study was to assess the therapeutic efficacy and safety of PEG-Dex in an Adriamycin-induced BALB/c mouse model of FSGS. A single dose of PEG-Dex treatment (35 mg/kg Dex dose equivalent) effectively reduced the proteinuria level, ameliorated FSGS lesions and restored kidney function when compared to the dose equivalent daily Dex treatment and Saline control. Additionally, PEG-Dex treatment also showed a much-improved safety profile than Dex with minimal adverse events detected.
