    摘要: Bispecific molecules which react both with the high-affinity Fcγ 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 BIV-infected cell). For this purpose, bispecific molecules can be constructed containing the binding region derived from an anti-Fcγ receptor antibody and the CD4 molecule or CD4 binding domain of the envelope glycoprotein gp120 of BIV. Alternatively, bispecific antibodies or heteroantibodies can be constructed containing the binding region derived from an anti-Fc receptor antibody and the binding region of 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: L'invention se rapporte à des molécules bispécifiques qui réagissent à la fois avec le récepteur Fcgamma d'affinité élevée de cellules effectrices humaines et avec un antigène de surface de cellules cibles. La liaison des molécules sur les récepteurs Fc se trouvant sur les cellules effectrices n'est pas bloquée par l'immunoglobuline G humaine. Ces molécules servent à cibler des cellules effectrices humaines (par exemple macrophages), contre des cellules portant l'antigène cible. A cet effet, on peut construire des molécules bispécifiques, qui contiennent la région de liaison dérivée d'un anti-corps de récepteur anti-Fcgamma et la région de liaison dérivée d'un anti-corps spécifique pour l'antigène cible. Les cellules effectrices ciblées peuvent être utilisées pour détruire des cellules portant l'antigène de surface de cellules cibles au moyen d'une cytolyse dépendant des anti-corps et faite par l'intermédiaire de cellules et au moyen d'une fixation par complément.

    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.
