Use of the antibody trastuzumab to kill HER2+ breast cancer cells is an attractive therapy because of its specificity and minimal adverse effects. However, a large fraction of HER2+ positive patients are or will become resistant to this treatment. No other markers are used to determine sensitivity to trastuzumab other than HER2 status.Using the xCELLigence platform and flow cytometry, we have c...
To develop a new immunotherapy for multiple myeloma, we have generated a monoclonal antibody (MoAb) that detects a human plasma cell-specific antigen, HM1.24. Our previous study has shown that mouse anti-HM1.24 MoAb inhibits the proliferation of human myeloma cells implanted into severe combined immunodeficiency mice. In this report, we evaluated the antitumor activity of the humanized anti-HM1...
Recent immune correlates analysis from the RV144 vaccine trial has renewed interest in the role of non-neutralizing antibodies in mediating protection from infection. While neutralizing antibodies have proven difficult to induce through vaccination, extra-neutralizing antibodies, such as those that mediate antibody-dependent cellular cytotoxicity (ADCC), are associated with long-term control of...
Increasing evidence indicates that antibody-dependent cellular cytotoxicity (ADCC) contributes to the control of HIV/SIV infection. However, little is known about the ADCC function of natural killer (NK) cells in non-human primate model. Here we demonstrated that ADCC function of NK cells was significantly compromised in chronic SIV/SHIV infection, correlating closely with the expression of Fcγ...
Interleukin 2 (IL-2) regulates immune responses by inducing proliferation and differentiation of T-cells into cytotoxic cells, inducing lymphokine activated killer activity and enhancing antibody dependent cellular cytotoxicity (ADCC). Lym-1, a monoclonal antibody, recognizes a membrane antigen present on the surface of B-lymphoma cells and can be used for ADCC. We therefore used Raji (human Bu...

Lym-1, a monoclonal antibody, recognizes a mem brane antigen present on the surface of B-lymphoma cells and can be used for ADCC. We therefore used Raji (human ...
Antibody-dependent cell-mediated cytotoxity (ADCC) can eliminate HIV-1 infected cells, and may help reduce the reservoir of latent virus in infected patients. Sera of HIV-1 positive individuals include a number of antibodies that recognize epitopes usually occluded on HIV-1 envelope glycoprotein (Env) trimers. We have recently described eCD4-Ig, a potent and exceptionally broad inhibitor of HIV...
Patients with active systemic lupus erythematosus (SLE) often have circulating antibodies to T cells. These patients also often have leukopenia and diminished numbers of T lymphocytes. In addition, certain T lymphocyte functions are frequently impaired in patients with SLE. It has been previously considered that a complement-dependent cytotoxic mechanism was responsible for the above observatio...
Adenoid cystic carcinoma (AdCC) of the salivary gland in the head and neck is characterized by indolent yet persistent growth, multiple local recurrences and early hematogenous metastasis. Considering the possible association between the epidermal growth factor receptor (EGFR) signaling pathway and angiogenesis in various types of cancer and the overexpression of EGFR in AdCC, it is reasonable ...
PURPOSE Removal of fucose residues from the oligosaccharides of human antibody is a powerful approach to enhance antibody-dependent cellular cytotoxicity (ADCC), a potential important antitumor mechanism of therapeutic antibodies. To provide clinically relevant evidence of this mechanism, we investigated ADCC of a fucose-negative version of trastuzumab [anti-human epidermal growth factor recept...
