dc.description.abstract | Targeted cancer therapies have been extensively tested with the purpose to selectively suppress tumor growth and to avoid harming healthy tissue. However, failure to escape endosomes upon receptor‐mediated endocytosis is a major obstacle limiting the efficacy of targeted cancer therapeutics. Here, novel target‐switchable intracellular toxin delivery systems (TiTDS) are presented which use the catalytic and translocation domain of diphtheria toxin (dtA‐T) as an intracellular toxin delivery platform and affibody molecules targeting human epidermal growth factor receptor 2 or epidermal growth factor receptor (HER2Afb or EGFRAfb) as target‐specific ligands. The intracellular toxin delivery platform and the affibody molecules are genetically fused with SpyCatcher (SC) protein and SpyTag (ST) peptide, respectively, to generate dtA‐T‐SC and ST‐HER2Afb or ST‐EGFRAfb modules. These modules can be individually purified and post‐translationally ligated to produce dtA‐T/HER2Afb or dtA‐T/EGFRAf. dtA‐T/HER2Afb and dtA‐T/EGFRAfb can selectively bind to their corresponding target cancer cells, efficiently enter the cells through receptor‐mediated endocytosis, successfully escape endosomes, and release toxins into the cytosol. They exhibit high target‐specific cytotoxicity in vitro and can significantly reduce tumor masses in vivo. TiTDS is a promising targeted cancer therapy platform because of its high target specificity, effective intracellular delivery of active toxins with improved therapeutic efficacy, and target switchability. | - |
