Lymphocyte Cytotoxicity in Alcoholic Hepatitis

Lymphocyte Cytotoxicity of oxLDL in Patients with Atherosclerosis

Background: Atherosclerosis, a chronic inflammatory disease of the vessel wall is characterized by local and systemic immune responses to a variety of antigens. Oxidized low-density lipoprotein (oxLDL) is considered as an important determining factor in the pathogenesis of atherosclerosis. Objective: The purpose of this study was to investigate the degree of peripheral blood mononuclear cells (...

Alcoholic hepatitis

Alcoholic hepatitis (AH) is a clinical syndrome characterized by jaundice and liver failure that generally occurs after decades of harmful alcohol consumption. Less severe forms of acute AH (AAH) frequently respond to alcoholic abstinence; whereas severe AAHs are characterized by a poor prognosis: up to 40-60% of these patients die within six months. Glucocorticoids currently remain the mainsta...

Lymphocyte-mediated Cytotoxicity in Vitro

The ability of antisera to suppress immune responses either in vivo or in vitro is well known. A variety of lymphocyte-target cell systems have been employed to demonstrate inhibition of cell-mediated immunity by antisera in vitro, and skin, tumor, and kidney graft survival have been prolonged by passively administered antiserum in vivo. An in vitro lymphocyte-tumor cell assay system was develo...

Molecular pathogenesis of T lymphocyte-induced liver injury in alcoholic hepatitis.

The development of alcohol-induced liver injury is, in part, a consequence of the immunological/inflammatory response that alcohol stimulates. The abnormalities of immune function in heavy drinkers have been documented well. Cytokines, especially TNF alpha, produced from macrophages/Kupffer cells, play a role in the induction of liver cell necrosis and apoptosis. TNF alpha can cause liver cell ...
