Its high prevalence, severe periodontal tissue destruction, and complex pathological mechanisms present substantial therapeutic challenges. Conventional therapies frequently fail to target underlying molecular pathological mechanisms. Ferroptosis, an iron-dependent form of regulated cell death characterized by iron accumulation and lipid peroxidation, has been increasingly implicated in diabetic periodontitis. However, translating ferroptosis inhibition into effective therapy remains problematic. Current strategies, primarily relying on single-pathway inhibitors, exhibit insufficient effectiveness. To overcome this, we engineered a bimetallic ZIF-8 codelivery nanoplatform (FGZ nanoparticles [NPs]) for sustained release of gallium ions (Ga\u00b3+) and canonical ferroptosis inhibitor ferrostatin-1 (Fer-1), synergistically integrating the functions of the 2 drugs. FGZ NPs potently activated the Nrf2\/HO-1 cytoprotective pathway, simultaneously reestablishing iron homeostasis and strengthening antioxidant capacity, resulting in effective dual-pathway ferroptosis inhibition. FGZ NPs demonstrated outstanding therapeutic outcomes, significantly promoting the regeneration of damaged periodontal tissues. This study validates ferroptosis as a promising target for diabetic periodontitis and introduces a novel strategy that surpasses the constraints of single-pathway ferroptosis inhibition, providing a new design framework for biomaterials targeting ferroptosis-related diseases.<\/jats:p>","DOI":"10.1177\/00220345251409777","type":"journal-article","created":{"date-parts":[[2026,2,12]],"date-time":"2026-02-12T04:36:33Z","timestamp":1770870993000},"page":"1285-1295","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Nano-Driven Dual Ferroptosis Inhibition for Diabetic Periodontitis Therapy"],"prefix":"10.1177","volume":"105","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-4065-5282","authenticated-orcid":false,"given":"Z.","family":"Zhao","sequence":"first","affiliation":[{"name":"State Key Laboratory of Oral Diseases &amp; National Center for Stomatology &amp; National Clinical Research Center for Oral Diseases &amp; Department of Prosthodontics, West China Hospital of Stomatology, Sichuan University, Chengdu, Sichuan, China"},{"name":"College of Polymer Science and Engineering, State Key Laboratory of Polymer Materials Engineering, Sichuan University, Chengdu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-6473-6020","authenticated-orcid":false,"given":"H.","family":"Feng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Oral Diseases &amp; National Center for Stomatology &amp; National Clinical Research Center for Oral Diseases &amp; Department of Prosthodontics, West China Hospital of Stomatology, Sichuan University, Chengdu, Sichuan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"X.","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Oral Diseases &amp; National Center for Stomatology &amp; National Clinical Research Center for Oral Diseases &amp; Department of Prosthodontics, West China Hospital of Stomatology, Sichuan University, Chengdu, Sichuan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.","family":"Cheng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Oral Diseases &amp; National Center for Stomatology &amp; National Clinical Research Center for Oral Diseases &amp; Department of Prosthodontics, West China Hospital of Stomatology, Sichuan University, Chengdu, Sichuan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W.","family":"Zhao","sequence":"additional","affiliation":[{"name":"College of Polymer Science and Engineering, State Key Laboratory of Polymer Materials Engineering, Sichuan University, Chengdu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0386-8262","authenticated-orcid":false,"given":"X.","family":"Pei","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Oral Diseases &amp; National Center for Stomatology &amp; National Clinical Research Center for Oral Diseases &amp; Department of Prosthodontics, West China Hospital of Stomatology, Sichuan University, Chengdu, Sichuan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,2,11]]},"reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"crossref","unstructured":"Bao J et al. 2023.
