monoclonal antibody therapy
The use of monoclonal antibodies to suppress immune function, kill target cells, or treat specific inflammatory diseases. Because of their high level of specificity, they bind to precise cellular or molecular targets. A potential problem associated with the use of monoclonal antibodies is an allergic reaction to the foreign antigens in the antibody, since they are created from mouse cells. Monoclonal antibodies have numerous uses in health care. SEE: table; hybridoma; monoclonal antibody.
