LIGHT deficiency attenuates acute kidney disease development in an in vivo experimental renal ischemia and reperfusion injury model.

ABSTRACT: Ischemia-reperfusion (I/R), a leading risk factor of acute kidney injury (AKI), is associated with high mortality and risk of progression to chronic kidney disease. However, the molecular mechanism of I/R-AKI remains not fully understood, which hinders its efficient clinical treatment. In this study, we observed that LIGHT deficiency remarkably attenuated I/R-AKI, as evidenced by rescued renal function, ameliorated tubular cell apoptosis, and alleviated inflammatory responses. Consistently, blocking LIGHT signaling with its soluble receptor fusion proteins (HVEM-IgG-Fc or LTβR-IgG-Fc) improved I/R renal dysfunction. RNA-sequencing and corresponding results indicated that LIGHT promoted oxidative stress and inflammation triggered by ischemic injury. Moreover, LIGHT signaling augmented ische
