  • Title: Local anesthetic articaine ameliorates LPS-induced acute kidney injury via inhibition of NF-ĸB activation and the NLRP3 inflammasome pathway.

    Abstract:
    The present study was conducted to determine the protective effect of articaine (ART) in an lipopolysaccharide (LPS)-induced acute kidney injury (AKI) animal model. The results suggest ART causes a significant decrease in serum blood urea nitrogen, creatinine, and serum cystatin C level, showing a protective effect against LPS-induced AKI. This has been further supported by histopathological findings of kidney tissues. The level of tumor necrosis factor-α, interleukin (IL)-6, and IL-1β in serum and kidney tissues was remarkably inhibited by ART in a dose-dependent manner. ART causes a significant reduction of malondialdehyde and increases the activities of glutathione and superoxide dismutase with an increase in dose as compared to the LPS-treated group. Moreover, the ART-treated group showed dose-dependent inhibition of LPS-induced nuclear factor-κB activation and TLR4 expression as confirmed by Western blot analysis. The level of Bcl-2 family genes (Bcl-2 and Bax) was restored near to normal by ART. Collectively, all the above results indicated that ART had protective effects against LPS-induced AKI by blocking inflammatory and oxidative responses.
