Abstract	To exploit the biological and pharmacological properties of immunoglobulin constant domain Fc fragment and increase the killing efficacy of T cells, a single chain variable fragment specific to CD3 was fused with Fcab (Fc antigen binding), a mutant Fc fragment with specificity against Human epidermal growth factor receptor 2 (HER2) developed by F-star. The bispecific fusion named as FcabCD3 was expressed by transient transfection in HEK-293T cells and purified by affinity chromatography. Specific cytolytic activity of retargeted T cells to kill HER2 positive SKBR3 cell line was evaluated in vitro. FcabCD3 was able to retarget T cells to kill both Herceptin insensitive Colo205-luc cell line and HER2 low expression MDA-MB-231-luc cell line. Furthermore, FcabCD3 was effective in eliminating the Colo205 tumor established on BALB/c nu/nu mice.
