  • Publication number: 20190321404
    Abstract: Disclosed herein is a novel chimeric antigen receptor and use thereof. The novel chimeric antigen receptor consists of a signal peptide, an antigen binding domain, a transmembrane region, and an intracellular signal domain, and comprises a 4-1BB signal peptide and/or a 4-1BB molecular transmembrane region. Nucleic acid sequences of various chimeric antigen receptors are separated and purified and provided is a chimeric antigen receptor and a CAR-T cell which are specific for a CD19 malignant tumor antigen. In the malignant tumor killing test of hematological cell lines, the ability of immune cells to target and recognize tumor cells is significantly enhanced, and the killing activity against tumor cells is also enhanced.
