Core Tip

Core tip: In this study, we found that urotensin-II (UII) increased before tumor necrosis factor (TNF)-α and interleukin (IL)-1β following lipopolysaccharide/D-galactosamine challenge. Furthermore, pretreatment with urantide, an inhibitor of the UII receptor, blocked TNF-α and IL-1β increases following downregulation of UII in liver and blood at different time points after challenge. Therefore, UII may play a pivotal role in the pathogenesis and priming of acute liver failure by triggering the inflammatory cascade, and initiating and driving the early release of TNF-α and IL-1β in lipopolysaccharide/D-galactosamine-challenged mice.
