Regulation of excessive inflammation and impaired cell proliferation is crucial for healing diabetic wounds. Although plant-to-mammalian regulation offers effective approaches for chronic wound management, the development of a potent plant-based therapeutic presents challenges. This study aims to validate the efficacy of turmeric-derived nanoparticles (TDNPs) loaded with natural bioactive compounds. TDNPs can alleviate oxidative stress, promote fibroblast proliferation and migration, and reprogram macrophage polarization. Restoration of the fibroblast-macrophage communication network by TDNPs stimulates cellular regeneration, in turn enhancing diabetic wound healing. To address diabetic wound management, TDNPs are loaded in an ultralight-weight, high swelling ratio, breathable aerogel (AG) constructed with cellulose nanofibers and sodium alginate backbones to obtain TDNPs@AG (TAG). TAG features wound shape-customized accessibility, water-adaptable tissue adhesiveness, and capacity for sustained release of TDNPs, exhibiting outstanding performance in facilitating in vivo diabetic wound healing. This study highlights the potential of TDNPs in regenerative medicine and their applicability as a promising solution for wound healing in clinical settings.
调控过度炎症和受损的细胞增殖对于糖尿病伤口的愈合至关重要。尽管植物向哺乳动物的调控为慢性伤口管理提供了有效的方法,但开发有效的植物性治疗方法仍然存在挑战。本研究旨在验证负载天然生物活性化合物的姜黄衍生纳米颗粒(TDNPs)的功效。TDNPs 可以减轻氧化应激,促进成纤维细胞增殖和迁移,并重新编程巨噬细胞极化。TDNPs 恢复成纤维细胞-巨噬细胞通讯网络,刺激细胞再生,从而促进糖尿病伤口愈合。为了解决糖尿病伤口管理问题,将 TDNPs 负载到由纤维素纳米纤维和海藻酸钠骨架构建的超轻、高溶胀比、透气的气凝胶(AG)中,得到 TDNPs@AG(TAG)。TAG 具有伤口形状定制的可及性、适应水的组织粘附性和 TDNPs 的持续释放能力,在促进体内糖尿病伤口愈合方面表现出优异的性能。本研究强调了 TDNPs 在再生医学中的潜力及其作为临床伤口愈合的有前途的解决方案的适用性。
