    Abstract: The present invention relates to an immune hepatotoxicity screening method using hepatocytes derived from human stem cells. After hepatocytes differentiated from human stem cells and human hepatocytes are treated with ethanol, CCl4, and acetaminophen to induce immune hepatotoxicity, a hepatocellular immunotoxic material assay system is constructed in order to verify cytokines, chemokines, and lipid mediators, which are mediators secreted from the hepatocytes, and an immunotoxic material can be confirmed in the cells having the induced hepatotoxicity by using the system. Therefore, the immune hepatotoxicity screening method using hepatocytes derived from human stem cells can be favorably used.

    Abstract: The present invention relates to a composition for the prevention and treatment of liver toxicity originated from acetaminophen comprising TNP (N2-(m-Trifluorobenzyl), N6-(p-nitrobenzyl)purine) as an active ingredient. The present inventors confirmed that TNP known as a 5-inosito pyrophosphate inhibitor suppressed apoptosis caused by acetaminophen in human embryonic stem cell-derived liver cells, mouse liver cells, and human hepatoma cell lines, up-regulated glutathione converted in liver cells, and inhibited JNK phosphorylation that is a kind of response against stress increased by acetaminophen. The inventors further confirmed that TNP had the activity of protecting liver cells from the toxicity caused by acetaminophen in an animal model. Therefore, TNP can be efficiently used as an active ingredient for a composition for the prevention and treatment of liver toxicity caused by acetaminophen.
