These limitations necessitate innovative strategies to enhance therapeutic efficacy and safety.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We designed and synthesized RBC@SeMSN@Uri, a red blood cell-coated biomimetic self-cascade bioreactor, which encapsulates uricase (Uri) and a selenium-based nano-scavenger (SeMSN) within RBC membranes. This design aims to reduce immunogenicity, extend systemic circulation, and maintain enzymatic activity. <jats:italic>In vitro<\/jats:italic> assays were conducted to evaluate biocompatibility, anti-inflammatory effects, and oxidative stress protection. <jats:italic>In vivo<\/jats:italic> experiments in hyperuricemia and gout models assessed therapeutic efficacy, biodistribution, and biosafety.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>RBC@SeMSN@Uri effectively degraded uric acid (UA) into allantoin and converted H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub> into water, preventing oxidative damage and inflammation. <jats:italic>In vitro<\/jats:italic> assays demonstrated excellent biocompatibility and reduced H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub>-induced inflammatory responses compared to free uricase. <jats:italic>In vivo<\/jats:italic>, the bioreactor prolonged circulation time, significantly reduced uric acid levels, alleviated kidney damage, and mitigated symptoms of hyperuricemia and gout. It also targeted inflamed joints, reducing swelling and inflammation in gouty arthritis models.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>This study presents RBC@SeMSN@Uri as a novel biomimetic strategy for enzyme replacement therapy in hyperuricemia and gout. By integrating uricase and selenium-based nano-scavenger within RBC membranes, the bioreactor addresses key limitations of traditional therapies, offering enhanced stability, reduced immunogenicity, and superior therapeutic efficacy. This platform holds potential for broader applications in protein or antibody delivery for enzyme replacement therapies in other diseases.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fbioe.2024.1520663","type":"journal-article","created":{"date-parts":[[2025,1,7]],"date-time":"2025-01-07T06:58:02Z","timestamp":1736233082000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["Biomimetic bioreactor for potentiated uricase replacement therapy in hyperuricemia and gout"],"prefix":"10.3389","volume":"12","author":[{"given":"Bin","family":"Yang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guihu","family":"Luo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tailei","family":"Nie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenglan","family":"Ban","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Quanxin","family":"Ning","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jialin","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiangru","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanhua","family":"Lin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaochun","family":"Xie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qianyun","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Han","family":"Zhong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pan","family":"Liao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chenyang","family":"Guo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chuanxu","family":"Cheng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erwei","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,1,7]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"862","DOI":"10.1016\/j.jconrel.2024.06.042","article-title":"Immunogenicity-masking delivery of uricase against hyperuricemia and gout","volume":"372","author":"Ban","year":"2024","journal-title":"J.
