Ischemia reperfusion (I/R) injury is a leading cause of acute kidney injury with
high morbidity and mortality due to limited therapy. NMDA receptor inhibitor
(DAP5) and resveratrol (Res) could ameliorate kidney I/R injury, but their use is
limited by low aqueous solubility and poor stability. Here, we examined the
potential protective effects of Res-DAP5 nanoparticles (NP) against renal I/R
injury. Mice were subjected to renal ischemia for 30 min followed by reperfusion
for 24 h. The results showed that Res-DAP5-NP could decreased serum creatinine
(Cr) and urea nitrogen (BUN), alleviated tubular damage and oxidative stress. In
addition, Res-DAP5-NP suppressed cell apoptosis, promoted the expression of
p-DAPK, and inhibited the expression of p-CaMK and p-AKT. Furthermore,
Res-DAP5-NP decreased the production of pro-inflammatory cytokines such as tumor
necrosis factor-?, IL-1?, IL-6, and p-I?B? induced by renal I/R injury. In
addition, Res-DAP5-NP also attenuated renal I/R injury in vivo, as manifested by
increase in cell viability, SOD level, and the expression of p-DAPK, decreases in
intracellular Ca2+ concentration and the expression of p-CaMK. Taken together,
our findings indicates that Res-DAP5-NP could effectively protect renal I/R
injury by inhibiting apoptosis and inflammation responses, possibly through
AKT/NMDA/CaMK/DAPK and NF-?B pathways.
