Abstract: The invention relates to a method of stimulating antibody-dependent cellular cytotoxicity to enhance the elimination of IgE-bearing B-cells comprising administering to a mammal an anti-IgE antibody, which binds to membrane bound IgE, but does not induce histamine release and administering an ISO to the mammal. The ISO may be a CpG containing oligonucleotide, or a modified CpG-containing oligonucleotide with an electron-withdrawing group at least at position C-5 of the cytosine in the CpG sequence. In addition, the method may include the administration of an allergen to improve desensitization therapy.

Abstract: A method of determining the antigens encoded by a genomic or cDNA library is disclosed. Dendritic or other antigen presenting cells are transfected with DNA fragments in a vector which includes a signal peptide coding sequence and an sequence which encodes a peptide binding to a receptor on the antigen presenting cell. The expressed DNA fragments are secreted under control of the signal peptide, and bind to a cell surface receptor. The antigen presenting cells are used to generate monoclonal antibodies. The monoclonal antibodies may be screened by cloning the same fragments into a display vector containing a transmembrane domain thereby displaying the expressed proteins on the surface of a host cell. The monoclonal antibodies are screened against these displayed proteins for a positive match.

Abstract: The invention is related to conjugates comprised of a pro-apoptotic protein encoded by Bak, Bak-2 or Bax genes and a ligand specifically targeting a cell surface antigen. The cell surface antigen is expressed on tumor cells, cells infected with bacteria or virus, or cells of specific functions, but it is not expressed or expressed only to a limited extent on other cell types. The ligand my be an organic molecule, an oligonucleotide, peptide, peptidomimetic, monoclonal antibody or derivative thereof, including fragments and single chain antibodies.

Abstract: A particular epitope located within the CD4-binding region of gpl20 of HIV-1, and antibodies specific for the epitope which can inhibit HIV-1 infection of human cells by diverse strains and isolates of the virus, is disclosed. The antibodies are useful for a number of purposes, including diagnosis of HIV-1 infection.

Abstract: Monoclonal antibodies are revealed which bind to the gp 120 protein on the envelope of HIV-1. These antibodies neutralize HIV-1. They inhibit the rate of infection of T cells, and also inhibit syncytium formation. Further, the antibodies are group-specific and neutralize different strains and isolates of HIV-1. These antibodies have a variety of uses, including the treatment and prevention of AIDS and ARC.

Abstract: The invention relates to a method of using a peptide which has the sequence of epitopes which are present on B cell-bound but not secreted IgA. This induces production of the antibody itself. These extracellular peptide segments form, entirely or in part, antigenic epitopes unique to membrane-bound but not secreted IgA.

Abstract: Murine monoclonal antibodies and related products such as antibody fragments, immunotoxins, human and humanized antibodies are disclosed, all of which bind to the gp120 protein on the envelope of HIV-1. These antibodies and related products neutralize HIV-1. They inhibit the infection of T cells, and also inhibit syncytium formation. Further, the antibodies are preferably group-specific and neutralize various strains and isolates of HIV-1. These antibodies have a variety of uses, including the treatment of AIDS and ARC, the prevention of HIV-1 infection, as well as a diagnostic application, in that they can be used for assaying of unknown fluid samples for HIV-1.

Abstract: The invention relates to unique extracellular peptide segments present on B cell-bound but not secreted IgA. These extracellular peptide segments form, entirely or in part, antigenic epitopes unique to membrane-bound but not secreted IgA, and thereby provide a unique epitope on the IgA-bearing B cells to which membrane-bound IgA is attached. These peptide segments can be used as immunogens to generate antibodies which specifically target membrane-bound IgA and IgA-bearing B cells.

Abstract: Antigenic epitopes associated with the extracellular segment of the domain which anchors immunoglobulins to the B cell membrane are disclosed. For IgA, the epitopes are present on IgA-bearing B cells but not the secreted, soluble form of IgA. The epitopes can be exploited for therapy and prophylaxis. For example, antibodies specific for the epitopes associated with the anchor and peptide encompassing the epitope domain of IgA can be used to increase secretory IgA production for the purposes of treating patients with infectious diseases and IgE-mediated allergic diseases.
