High mobility group B1 impairs hepatocyte regeneration in acetaminophen hepatotoxicity
BACKGROUND Acetaminophen (APAP) overdose induces massive hepatocyte necrosis. Necrotic tissue releases high mobility group B1 (HMGB1), and HMGB1 contributes to liver injury. Even though blockade of HMGB1 does not protect against APAP-induced acute liver injury (ALI) at 9 h time point, the later time points are not studied and the role of HMGB1 in APAP overdose is unknown, it is possible that ne...
متن کاملAcetaminophen-related hepatotoxicity.
Acetaminophen (APAP) is the leading worldwide cause of drug overdose and acute liver failure (ALF). Single overdose ingestion and therapeutic misadventure may cause hepatotoxicity. Several factors, such as concomitant alcohol use or abuse, concurrent medications, genetic factors, and nutritional status, can influence the susceptibility and severity of APAP hepatotoxicity. Early manifestations o...
متن کاملPlatelets mediate acetaminophen hepatotoxicity.
In this issue of Blood, Miyakawa et al show that platelets and protease-activated receptor (PAR)-4 contribute to acetaminophen (APAP)-induced liver damage. Using various strategies in a mouse model of APAP overdose, the authors demonstrate that platelets participate in the progression of liver damage, and that the direct thrombin inhibitor lepirudin and PAR-4 deficiency attenuate hepatotoxicity...
متن کاملAcetaminophen-induced hepatotoxicity.
The analgesic acetaminophen causes a potentially fatal, hepatic centrilobular necrosis when taken in overdose. The initial phases of toxicity were described in Dr. Gillette's laboratory in the 1970s. These findings indicated that acetaminophen was metabolically activated by cytochrome P450 enzymes to a reactive metabolite that depleted glutathione (GSH) and covalently bound to protein. It was s...
متن کاملFreshly isolated hepatocyte transplantation in acetaminophen-induced hepatotoxicity model in rats.
CONTEXT Hepatocyte transplantation is an attractive therapeutic modality for liver disease as an alternative for orthotopic liver transplantation. OBJECTIVE The aim of the current study was to investigate the feasibility of freshly isolated rat hepatocyte transplantation in acetaminophen-induced hepatotoxicity model. METHODS Hepatocytes were isolated from male Wistar rats and transplanted 2...
