Bi-specific antibody-like complexes have multiple modes of action including: (1) inhibition of two different cell surface receptors; (2) blocking of two ligands; (3) crosslinking of two receptors; (4) delivery of toxins or death inducing agents to kill tumor cells; and (5) T cell recruitment to the proximity of tumor cells to induce antibody-dependent cellular cytotoxicity, also named redirected lysis [7]. This evidence concerns the gene CD177 and neoplasm.
