Description

This session highlights novel basic science research investigating mechanisms of hepatoxicity. This session spans liver injury and repair for a variety of disease models including acetaminophen-induced liver injury, ethanol hepatoxicity, induction of tumorgenesis and HCC, and the role of coagulation in severe acute liver injury.

Drug-Induced Liver Injury

Objectives

  • Describe key pathways for inflammation and recovery in acetaminophen-induced liver injury.
  • Discuss the interplay of metabolic factors, ammonia production, and development of HCC in pre-clinical models.
  • Outline the interplay of immune cells in drug toxicity and liver recovery.
