Higher serum HSP70 predicted poorer clinical recovery in Kaplan\u2013Meier analysis. Neutralizing antibody inhibition of circulating HSP70 reduced liver injury in liver failure mice (ALT reduction: 43%, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05), while exogenous HSP70 worsened it (ALT increase: 2.86\u2010fold, p\u2009&lt;\u20090.05) via increased macrophage proinflammatory production. Besides, the HSP70 inhibitor blocked TNF\u2010\u03b1\u2010mediated apoptosis by inhibiting the NF\u2010\u03baB pathway. Notably, ginseng metabolite 20(<jats:italic>S<\/jats:italic>)\u2010protopanaxadiol (aPPD) was a natural HSP70 inhibitor (IC<jats:sub>50<\/jats:sub>\u2009=\u20092.85\u2009\u03bcM), preventing liver failure severity (ALT reduction: 92%) and reducing mortality by 64%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>These findings underlined the immunopathologic role of HSP70 and a promising therapeutic target in liver failure.
