Özet

Sepsis-induced acute liver injury is a life-threatening condition involving inflammation, oxidative stress, and endothelial dysfunction. In the present study, the preventive effects of resveratrol (RV) alone and RV-loaded silver nanoparticles (AgNPs + RV) against sepsis-induced damage were investigated and compared in a rat model of polymicrobial sepsis induced by cecal ligation and puncture (CLP). Rats were divided into four groups: Sham, CLP, RV, and AgNPs + RV. Pro-inflammatory cytokines (TNF-alpha, IL-1 beta, IL-6), nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappa B) activation, presepsin, procalcitonin (PCT), 8-hydroxy-2 '-deoxyguanosine (8-OHDG), vascular endothelial growth factor (VEGF), and sirtuin-1 (SIRT1) levels were assessed to determine the treatments' effects. AgNPs + RV treatment significantly reduced pro-inflammatory cytokines, NF-kappa B activation, presepsin, PCT, 8-OHDG, and VEGF levels compared with the CLP group, indicating attenuation of sepsis-induced liver injury. Both RV and AgNPs + RV treatments increased SIRT1 levels, suggesting a potential role of SIRT1 activation in mediating the protective effects. In conclusion, AgNPs + RV treatment demonstrated extremely enhanced efficacy in alleviating sepsis-induced liver injury by modulating inflammation, oxidative stress, and endothelial dysfunction, potentially mediated through SIRT1 activation. In this study, the effect of AgNPs + RV on sepsis was evaluated for the first time, and these findings highlight AgNPs + RV as a promising therapeutic strategy for managing sepsis-induced liver injury, warranting further investigation.
