  • Patent number: 7456264
    Abstract: Isolated human monoclonal antibodies which bind to Anthrax protective antigen are disclosed. The human antibodies can be produced in a non-human transgenic animal, e.g., a transgenic mouse, capable of producing multiple isotypes of human monoclonal antibodies by undergoing V-D-J recombination and isotype switching. Also disclosed are derivatives of the human antibodies (e.g., bispecific antibodies and immunoconjugates), pharmaceutical compositions comprising the human antibodies, non-human transgenic animals and hybridomas which produce the human antibodies, and therapeutic and diagnostic methods for using the human antibodies.

  • Patent number: 6365161
    Abstract: Multispecific molecules which target immune cells are disclosed. The molecules are “multispecific” because they bind to multiple (two or more), distinct targets, one of which is a molecule on the surface of an immune cell. Multispecific molecules of the invention include molecules comprised of at least one portion which binds to a molecule on an effector cell, such as an Fc receptor, and at least one portion (e.g., two, three, four or more portions) which binds to a different target, such as an antigen on a tumor cell or a pathogen. Multispecific molecules of the invention also include antigen “multimer complexes” comprised of multiple (i.e., two or more) portions which bind to a molecule on an antigen presenting cell (APC), such as an Fc receptor, linked to one or more antigens. These multimer complexes target antigens, such as self-antigens, to APCs to induce and/or enhance internalization (endocytosis), processing and/or presentation of the antigen by the APC.
