Abstract

Aims

Gouty arthritis (GA), a prevalent and intricate form of inflammatory arthritis, affects individuals across all age groups. Existing therapeutic agents for GA are associated with substantial adverse effects. The overarching objective of this study is to identify an efficacious and biocompatible intervention strategy for GA.

Materials and methods

In this investigation, we developed a zinc ferrite nanoparticle (ZFN) characterized by outstanding catalytic activities in anti-inflammatory and antioxidative processes, along with negligible biotoxicity. ZFN features low-content Zn²⁺ doping, which effectively overcomes the issue of low biocompatibility commonly encountered in Zn-based nanoparticles. Both in vitro and in vivo experimental models were utilized to comprehensively evaluate the effects of ZFN.

Key findings

The experimental results demonstrate that ZFN exhibits remarkable efficacy in alleviating inflammation and oxidative stress both in vitro and in vivo. It exerts its therapeutic effect on GA by modulating the NF-κB signaling pathway, suppressing the activation of the NLRP3 inflammasome, and activating the Nrf2 pathway.

Significance

The protective effect of ZFN against GA holds great promise for the clinical translation of biocompatible inorganic nanoplatforms in the treatment of GA. This finding offers a potential alternative to the currently available medications, thereby providing new insights and possibilities for the management of GA.

期刊介绍： Life Sciences is an international journal publishing articles that emphasize the molecular, cellular, and functional basis of therapy. The journal emphasizes the understanding of mechanism that is relevant to all aspects of human disease and translation to patients. All articles are rigorously reviewed. The Journal favors publication of full-length papers where modern scientific technologies are used to explain molecular, cellular and physiological mechanisms. Articles that merely report observations are rarely accepted. Recommendations from the Declaration of Helsinki or NIH guidelines for care and use of laboratory animals must be adhered to. Articles should be written at a level accessible to readers who are non-specialists in the topic of the article themselves, but who are interested in the research. The Journal welcomes reviews on topics of wide interest to investigators in the life sciences. We particularly encourage submission of brief, focused reviews containing high-quality artwork and require the use of mechanistic summary diagrams.
