Taurine inhibits necroptosis helps to alleviate inflammatory and injury induced by Klebsiella infection

Klebsiella infection is widely acknowledged to inflict severe inflammatory damage in bovines. Herein, we demonstrate significant death of EpH4-Ev cells incubated with Klebsiella. And compelling evidence shows that Klebsiella infection increases interactions between the Receptor-interacting serine/threonine-protein kinase 1 (RIPK1) and RIPK3, which promotes phosphorylation of RIPK3 and MLKL to induce necroptosis. However, these changes can be partially reversed by taurine and Nec-1s. Moreover, using taurine and Nec-1s to partially inhibit necroptosis significantly reduce TNF-alpha, IL-1 beta and IL-6 levels and NAGase activity induced by Klebsiella infection. Taken together, taurine partially inhibits necroptosis induced by Klebsiella infection and hence alleviates inflammatory and injury in EpH4-Ev cells.

Automated summary

This study investigates the inflammatory damage caused by Klebsiella infection. The results demonstrate that necroptosis induced by Klebsiella infection can be partially reversed by taurine and Nec-1s, leading to reduced production of inflammatory cytokines.
