For alleviating losses, immersion vaccination is an extremely promising maneuver to prevent and curb on SVCV infection. In our previous research, we designed a modular immersion nanovaccine (LSG-TDH) targeting SVCV, and found that it could induce not merely mucosal immunity but systemic immune responses in zebrafish. Nevertheless, our previous research was unable to elaborate on how LSG-TDH were taken up by the cells. Thereby, this study aimed to investigate its transmembrane transport mechanism <em>in vitro</em> using epithelioma papulosum cyprini (EPC) cells and macrophages as models. The transmembrane transport mechanism of LSG-TDH on EPC cells and macrophages was analyzed by cell fluorescence, flow cytometry and chemical inhibitor experiments. The results showed that the entry of LSG-TDH into cells was time-dependent and energy-dependent. Chlorpromazine significantly inhibited the transmembrane transport of LSG-TDH. The contents of LSG-TDH into EPC cells and macrophages after treated with chlorpromazine decreased by 80 % and 71 %, respectively. It is indicated that the transmembrane transport of LSG-TDH was mainly achieved through clathrin-mediated endocytosis pathway. This study provides a reference for the delivery mechanism of aquatic nanovaccine, which has important scientific significance and application prospect.</div></div>","PeriodicalId":100941,"journal":{"name":"Nano TransMed","volume":"4 ","pages":"Article 100077"},"PeriodicalIF":0.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143577942","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}

Researchers are studying different kinds of NPs, like liposomal, polymeric, dendritic, and gold nanoparticles (AuNPs), to see how they can improve drug delivery and change the tumour environment. To improve treatment results, we use specific strategies like targeting receptors, releasing substances inside cells in a controlled way, and adjusting the immune response. The review talks about how NPs focus on cancer-related fibroblasts, stop new blood vessel growth, and tackle problems in moving these treatments into real-world use. These issues include safety, toxicity, being able to produce them on a large scale, and following regulations. Finally, emerging trends, such as hybrid NPs and personalized nanomedicine, are proposed. Nanoparticle technology can greatly change how we treat head and neck cancer.
