Abstract:
Monoclonal antibodies which react specifically to Fc receptor of human effector cells IgG are disclosed. Binding of the antibodies to the receptor is not blocked by human immunoglobulin G. The antibodies are useful for targeting human effector cells (e. g. macrophages) against a target cell (e. g. a cancer cell, an infectious agent, etc. ) For this purpose, bifunctional antibodies or heteroantibodies can be constructed containing the binding region derived from an anti-Fc receptor antibody and the binding region of a target-specific antibody. Targeted effector cells can be used to kill target cells by cell mediated antibody dependent cytolysis.
