Neutrophil extracellular traps(NETs) have recently been found to be a new immune mechanism for neutrophils to kill pathogens.The main component of NETs is DNA,with granular proteins of different sizes attached to the surface. NETs play different roles in various liver diseases such as hepatic ischemia-reperfusion injury,chronic hepatitis B,liver cirrhosis,and liver cancer. This article reviews the formation mechanism,structure,and role of NETs in liver diseases.
