Abstract: A binary vector and the provision of expression of a target antigen-dependent regulatory cytokine using the synNotch technology, so as to partially release the cytokine to enhance the function of T cell and reduce the non-specific toxic and side effect of the cytokine. A synthetic notch receptor is used to construct plasmid vectors to achieve local cytokine secretion. One plasmid vector uses a specific antibody as an extracellular domain for identifying a target antigen, a notch core comprises a transmembrane domain and a specific enzyme cutting site on a notch receptor, and transcription factor GAL4VP64 is used as an intracellular domain. When the target antigen is identified, the enzyme cutting site on the notch will be identified by a corresponding enzyme to hydrolyze and cut the intercellular transcription factor GAL4VP64.
