Abstract

In liver biopsies of 37 patients with chronic active liver disease (CALD) the inflammatory infiltrate was studied with monoclonal antibodies to the surface antigens on helper/inducer (OKT4+), suppressor/cytotoxic (OKT8+), killer/natural killer (OKM1,2+) cells and common T cell antigens (OKT1+, OKT3+). Furthermore OKT11 antibody was applied, which defines the E rosette receptor. Special emphasis was given to areas with piece-meal necrosis (PMN). In areas with PMN in idiopathic autoimmune CALD (IA-CALD, n = 15) OKT8+ and OKM+ lymphocytes and IgG plasma cells were present, whereas in hepatitis B-CALD (HB-CALD, n = 12) almost exclusively OKT8+ cells were found. In PBC (n = 10) OKT4+ cells in central parts of portal tracts and OKT8+ cells in areas with PMN predominated. These findings indicate that in IA-CALD antibody-dependent cell-mediated cytotoxicity (ADCC), as well as T cell cytotoxicity may be responsible for liver cell damage, while in HB-CALD T cell cytotoxicity seems to be the only mechanism. In PBC liver cell damage also predominantly is the result of T cell cytotoxicity. In addition, helper T lymphocytes seem to play a role since these are found in central areas of the portal tracts.

Autoimmune Hepatitis

Autoimmune hepatitis formerly called lupoid hepatitis, is a chronic, autoimmune disease of the liver that occurs when the body's immune system attacks liver cells causing the liver to be inflamed. Discover the latest research on autoimmune hepatitis here.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Adrenocortical Carcinoma

Adrenocortical carcinoma (ACC) is a rare malignancy of the adrenal cortex, associated with a generally dismal prognosis owing to its aggressive behavior. Here are the latest discoveries pertaining to this disease.

B cell Differentiation

Depending on the signal received through the B cell receptor and other receptors, B cells differentiate into follicular or marginal zone B cells. Here is the latest research pertaining to this differentiation process.

Antibody-Dependent Cell Cytotoxicity

Antibody-dependent cellular toxicity refers to the lysis of a target cell by a non-sensitized effector cell of the immune system as a result of antibodies binding to the target cell membrane and engaging the Fc receptors on the immune effector cells. Find the latest research on antibody-dependent cellular toxicity here.

Autoimmune Hemolytic Anemia

Autoimmune hemolytic anemia (AIHA) occurs when antibodies directed against the person's own red blood cells (RBCs) cause them to burst (lyse), leading to an insufficient number of oxygen-carrying red blood cells in the circulation. Discover the latest research on AIHA here.
