Autoimmune hepatitis (AIH) is a chronic liver inflammation of unknown etiology that is characterized by the presence of circulatory autoantibodies and ongoing liver tissue damage.

Researchers at UT Southwestern Medical Center have found that individuals who carry a specific form of the gene PNPLA3 have more fat in their livers and a greater risk of developing liver inflammation.

Researchers reveal a new protein that prevents the hepatitis C virus from replicating, which could help devise new drugs against hepatitis C.
