    摘要： Bispecific molecules which react both with the high-affinity Fcη receptor of human effector cells and with a virus or virus component are disclosed. Binding of the molecules to the Fc receptors found on effector cells is not blocked by human immunoglobulin G. The molecules are useful for targeting human effector cells (e.g. macrophages) against a viral target (e.g. HIV or HIV-infected cell). For this purpose, bispecific molecules can be constructed containing the binding region derived from an anti-Fcη receptor antibody and the CD4 molecule or CD4 binding domain of the envelope glycoprotein gp120 of HIV. Alternatively, bispecific antibodies or heteroantibodies can be constructed containing the binding region derived from an anti-Fc receptor antibody and the binding region of a HIV-specific antibody such as anti-gp120 antibody. Targeted effector cells can be used to kill virus by cell mediated antibody dependent cytolysis.

    摘要： A human Fc receptor-specific monoclonal antibody is disclosed together with its mode of preparation. Binding of the antibody to Fc receptor is not blocked by human immunoglobulin G. The antibody binds to the high affinity Fc receptor for IgG on human monocytes at a receptor binding site distinct from the ligand binding site for Fc. A bifunctional antibody or a heteroantibody has an antigen binding region derived from an anti-Fc receptor antibody and an antigen binding region specific for a target epitope or cell; such antibody may target a macrophage when it is bound to surface Fc receptors of the macrophage. A target-specific effector cell expresses receptor for the Fg portion of IgG, has one antigen binding region derived from an anti-Fc receptor antibody and another specific for a target cell, and the aforesaid bifunctional or hetero-antibody is bound to the Fc receptor of the effector cell; such effector cell can be used in the therapy of cancers, allergies, infectious and autoimmune diseases, and in immunoassays.
