  • Publication number: 20240122976
    Abstract: The present invention provides an immune effector cell that comprises a chimeric antigen receptor (CAR) specific for a tag of a tagged polypeptide, wherein said polypeptide binds to an antigen of a target cell, and a chimeric costimulatory receptor (CCR) specific for a further antigen.
