Dual therapy for amanita phalloides-induced acute liver failure in mice: A combination of etanercept and alpha-1 antitrypsin

Background The toxin α-amanitin from Amanita phalloides induces hepatocyte death and disrupts local and systemic immune responses, key drivers of acute liver failure (ALF). Although TNF-α plays a central role in ALF, TNF-α-targeted therapies alone have sho ...
