Interleukin-22 therapy: Providing new hope for alcoholic hepatitis



Alcoholic hepatitis is a severe form of alcoholic liver disease, and how the condition progresses is largely unknown. No FDA-approved therapies exist at this time.


IRP researchers led by Bin Gao, M.D., Ph.D., established a new animal model (chronic-plus-binge ethanol feeding) that better mimics human patterns of alcohol abuse than previous models, reproducing some features of liver damage and inflammation in patients with alcoholic hepatitis. Dr. Gao’s group discovered that interleukin-22 is a protein with the ability to protect the liver from damage and promote liver regeneration.


Interleukin-22 is currently the subject of clinical trials for the treatment of alcoholic hepatitis. The chronic-plus-binge model is now widely used for studying the development and progression of early alcoholic hepatitis.
