Regulatory T cells suppress excessive lipid accumulation in alcoholic liver disease.

ABSTRACT: Sensitization of hepatic immune cells from chronic alcohol consumption gives rise to inflammatory accumulation, which is considered a leading cause of liver damage. Regulatory T cells (Tregs) are an immunosuppressive cell subset that plays an important role in a variety of liver diseases; however, data about pathological involvement of Tregs in liver steatosis of alcoholic liver disease (ALD) is insufficient. In mouse models of ALD, we found that increased lipid accumulation by chronic alcohol intake was accompanied by oxidative stress, inflammatory accumulation, and Treg decline in the liver. Adoptive transfer of Tregs relieved lipid metabolic disorder, oxidative stress, inflammation, and, consequently, ameliorated the alcoholic fatty liver. Macrophages are a dominant source of inflammati
