Abstract
The overexpression of inflammatory factors is closely related to the pathogenesis of acute kidney injury (AKI). Additionally, the overproduction of reactive oxygen species (ROS) further exacerbates the inflammatory response. In light of this, monotherapies focused solely on inflammation have proven to be suboptimal. Therefore, this study successfully developed a nanoparticle (SC@Se/GA) that possesses anti-inflammatory and antioxidant properties. The SC@Se/GA has a smaller size, better stability, and kidney-targeting. In vivo experiments showed that the GPx enzyme activity of SC@Se/GA increases by almost 50 % more than SC@Se alone, indicating its efficient ability to scavenge ROS. In the meantime, SC@Se/GA has a longer renal retention period (>24 h) than free drug GA, which can dramatically lower the levels of inflammatory factors TNF-α and IL-6. In summary, SC@Se/GA, through its synergistic anti-inflammatory and antioxidant effects, markedly alleviates CDDP-induced renal injury and restores renal function, providing a new effective strategy for treating AKI.
