Antibody-dependent cellular cytotoxicity (ADCC) is mediated by genetically modified antigen-specific human T lymphocytes.
In the context of transplantation, donor and virus-specific T-lymphocyte infusions have demonstrated the dramatic potential of T cells as immune effectors. Unfortunately, most attempts to exploit the T-cell immune system against nonviral malignancies in the syngeneic setting have been disappointing. In contrast, treatments based on monoclonal antibodies (Abs) have been clinically successful and...
متن کاملMonocyte-mediated antibody-dependent cellular cytotoxicity: a clinical test of monocyte function.
The lack of a simple, rapid, and quantitative test of the functional activity of the monocyte has hampered studies of the contribution of this cell type to host defense and human disease. This report describes an assay of antibody-dependent cellular cytotoxicity, which depends exclusively upon the monocyte as the effector cell and therefore provides a convenient test of monocyte function. In th...
متن کاملUsing impedance-based approaches for measuring cell-mediated cytotoxicity and antibody-dependent cell-mediated cytotoxicity (ADCC)
The most common method for measuring cell-mediated cytotoxicity is the release assay. Effector cell-mediated disruption of the target cell membrane results in leakage of its cytoplasmic contents into the culture medium. Endogenous biomolecules (such as lactate dehydrogenase) or previously added exogenous labels (such as the radioisotopes Cr or In) that leak into the media are then measured as a...
متن کاملAntibody-dependent cell-mediated cytotoxicity (ADCC) toward human O+ red cells coated with anti-D antibody: comparison between lymphocyte and monocyte ADCC activity.
We investigated the antibody dependent cell-mediated cytotoxicity (ADCC) of lymphocytes and monocytes toward human O+ red cells coated with anti-D antibody using a 51Cr release assay. Lysis of sensitized red cells by lymphocytes occurred rapidly, but monocyte-mediated lysis occurred slowly. This difference might be due to postphagocytic 51Cr release by monocytes. ADCC of lymphocytes increased i...
متن کاملHuman monocyte antibody-dependent cell-mediated cytotoxicity to tumor cells.
Previous investigations of mononuclear cell antibody-dependent cell-mediated cytotoxicity (ADCC) toward tumor cells suggest that K lymphocytes and not monocytes are active in this cytotoxic reaction. This report, however, demonstrates that human monocytes are able to carry out ADCC toward three different human tumor cell lines (CEM T lymphoblasts, Raji bone marrow-derived (B) lymphoblasts, and ...
