Abstract

The present study characterized the cytotoxic capabilities of human T lymphocyte subpopulations against human red blood cells (HRBC) and autologous lymphoid cells in an antibody-dependent cellular cytotoxicity (ADCC) assay. T cells bearing Fc receptors for immunoglobulin IgG (TG) were capable of lysis of antibody-coated HRBC and autologous lymphoid cells while T cells with surface Fc receptors for IgM (TM) displayed no ADCC activity TG-cell mediated ADCC could be inhibited by blockage of surface Fc receptors following treatment with aggregated Ig. Null cells and low-affinity E-rosette forming cells were also capable of similar ADCC activity against these targets.

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.

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.
